Can anyone help me with PH508 everytime when I use ARM HOME or ARM AWAY the PH508 always sound for 1-2 second then off.
I tried set PH508's House code and Unit code same as system console but i just don't like the sound everytime when i pressed ARM button.
I tried set the same House code but with different Unit code but did not hear the sound from Power Horn.
What setting i really need? please help
thanks
-
One to two second sounds is not normal.
Are you using the older PS561 console in the DS7000 Kit or the new SC1200A console?
If it is the PS561 set the unit code to any unit number but the Security Light Unit Code. House Code to match the one set on the console.
It should only sound after an alarm starts flashing the lights for about two or more cycles.
If it is the SC1200A it has to be set to the Security Light Code or the Security Light Code +1 unit code.
What is the date code {small white round sticker} on the PH508?
-
its kind of bother me because at night when ARM home wake someone up while they sleep.
i am using 2 powerhorns date code 08G31
using SC1200
what is correct setting? i may just follow what you tell me been spent so much time tried fixed this issued
thank you
-
what do you mean by this " set to the Security Light Code or the Security Light Code +1 unit code."????? i don't use any light at all.
i don't know much about this very sorry asking this question.
thanks
-
I believe you may already have it set.
First or second Security Light Code is what X10 says is needed.
Example if you have it set to B House Code, Light Code 1. PH508 set to either B1 or B2 is what the settings should be.
I will see if I can find anything more on this as I know when X10 made the Radio Shack 49-1000 {very similar to the SC1200A} Powerhorns where a problem back in 2005.
I also know my old PH508s and 2010 PH508s act differently with a SC1200A.
Setup menu #7 OPTIONS. Page 26 of manual.
You can set the House Code the console uses and the unit code {called Light Code}.
If you didn't set it it will be A1 and A2. By default.
Page 35:
Any module set to that address will flash on an alarm.
On an arm home. Will go On and Off to indicate it was set.
On an arm away. Lights go on and go off a minute later after the exit delay times out.

Brian H,
Fist of all i would like to say thank you,
i have 3, PH508 date code 08G31 and 2)09A03
Also i notice after play aound with siren the console sound low pitch just sounds like someone sick with the soarthrout but to fix it i have to removed the battery and diconnect power adaptor for a minut then the sound return back to normal.
thanks million

I'm a bit confused here on PH508 there are Two dial:
1, Housecode
2, Unit Code 1-16
what light code??
thanks
-
SC1200A calls it a Security Light Code. Most would call them the House Code Unit Code Address.
Basically it is the address; House Code and Unit Code; a lamp module or wall switch is set to will flash with an alarm or go on and off to indicate arming.
If you never reset the House Code and Light Code {Unit Code Dial on Module} in the SC1200A Options menu.
The PH508 should be set to House Code A Unit Code 1. Since the SC1200 can control two addresses. The second is again House Code A and this time Unit Code 2.
So set the PH508s to A1 or A2 if you have not reset them in the options menu of the SC1200A.
-
i have done reset several times.
"SC1200"
House code A
Lightcode 1
"PH508"
Housecode to #??
Unit Code to #???
i just want to use one PH508 for now to see how it work.
-
Try A1. On each PH508 you want to add to the system.
If that doesn't work correctly. Try A2.
-
if i set to PH508 A1 the same as SC1200 A1 will work but the powerhorn will sound for a fer moments when arm the system this will wake someone up at night.
-

thanks for your time trying to help.

You are welcome.
We have been testing PH508s and SH10As with the SC1200A and various date codes act differently.
I think X10 was trying to get the Powerhorns to work with the Radio Shack 49-1000MC console they made for them. In late 2004.
Back then we has reports of them not working correctly. The SC1200A is not that much different than the 49-1000MC.
Thank you for all the data you provided on your date codes and results.
It will be added to our information.
I can make my modified timing component PH508 do exactly what yours is doing.
It was modified to trigger with fewer on off cycles in an feeble attempt to make it work with an SC1200A.
-
Just went back over your posts.
How did you make it go into the strange sound making?
-
i have no idea why make strange sound it happen twice when armed and i open the door the alarm will sound then i disarm the unit this is how the sound did change to lower tone on both chime and exit delay sound to fix it remove battery and unplug power to solve the problem.
would you please try to set your sc1200 and your ph508 the same Housecode and Lightcode you will hear the sound for the moment from ph508 when press arm home.
thank you
-
None of mine sound with an arm home or away when set to the required Security Light Codes. Like yours do.
I reset mine to A1 just on the chance my B1 B2 was different. It was not.
My older date code ones do sound with an alarm. 2002-2005
My two 2010 ones. Take a long time to trigger on an alarm. Then sound for 4 cycles. Stop for ten seconds. Then sound again for four cycles.
How yours act may depend on the date codes.
Not sure when the PH508 was redesigned. It may have been in the date code range you have.
Some of my tests along with other users comments are in these threads.

The strange acting sounds you get sometimes may indicate the SC1200A has a problem. maybe you should call X10 support and see what they think.
-
Descovered new problem the unit shown Low Batt i replaced new battery again now show Low Batt again for me nothing but problem.
i'm out of option.
-
i'm out of option.
Send it back, sounds like another example of the X10 customer being the final quality inspector.
-
With low battery all the time. Strange sounds for no reason and setting off powerhorns when armed.
Sounds like it is defective.
-
one final question
what is your SC1200 setting?
HouseCode??
Light Code??
what is your PH508 setting?
HouseCode??
Unit Code??
-
SC1200
House Code B
Light Code 1
PH508
House Code B
Unit Code 1
I also tried your settings.
SC1200
House Code A
Light Code 1
PH508
House Code B
Unit Code 1.
All the same. Never sounded the siren when armed home or away. With three PH508's and an X10Pro PSH01.
-
If you want to try a manual test.
Use the keyboard buttons.
With the PH508 on House Code A Unit Code 1
SC1200 House Code A Lights Code 1
Push the #1 key then On
Push the #1 key then Off.
If you continue the on off cycles. Eventually the PH508 should go into a full blown high low siren sound and continue until you stop the on off cycles.
-
your first setting my powerhorn will sound for the moment when arm.
your 2nd setting no sound at all from powerhorn only console
-
Well my second settings has a BIG typo in it. ???
With the House Code mismatch. It definitely would not have sounded.
For the second set try:
SC1200
House Code A
Light Code 1
PH508
House Code A
Unit Code 1.
-
SC1200
House Code A
Light Code 1
PH508
House Code A
Unit Code 1.
this setting everything works but the only thing that bother me is PH508 will sound for the moment just enough to wake someone up at night.
-
If the low battery LED still stuck ON?
If it is still make strange sounds sometimes? That require a battery removal and power cycle to correct.
A short Powerhorn sounding with an arm home or arm away. Is not normal.
I would consider calling X10 and getting a warranty exchange.
-
i tried all Three powerhorns they all acting the same maybe console that gave me the problem.
Oh! by the way with Low Batt LED some how one of my window sensor zone 10 maybe bad shown on console #10 now replaced with new one Low Batt went away.
now need to see what will be the next problem will let you know.
thanks million for your time for trying to help me

OK keep us in the loop.

i just found this from Kbase.x10 see below
How do I add a PowerHorn siren to my system?
When I alarm the system in the Delay mode, is my siren supposed to make noise?
Answer
Installing the Power Horn
Set the House Code dial to the same House Code as the Security System
Set the Unit Code dial to an unused code. If the Unit Code dial is set to the same as the main console, the horn will sound a few moments when you arm the system (which could unnecesarily awaken members of your household), and the alarm will sound whenever the lights flash. Plug the Power Horn into a convenient AC outlet, preferably an unswitched one to ensure that the Power Horn cannot be turned off accidentally.
Testing the Power Horn[/color]Press the ON button on any X10 controller or remote which corresponds to the same House Code and Unit Code as the Power Horn, hold the button pressed for several seconds. The siren will continue for 4 minutes, or until an OFF command is received.
Trigger the security system by pressing the PANIC button on the console or on a remote. The Power Horn will be activated automatically in the next 4 seconds after the alarm has been triggered and will continue for around 4 seconds after the system is disarmed.
-
That information sounds like an error.
It is for the OLD DS7000 Security Kit.
Where the console sends an All Lights On All Units Off to trigger a Powerhorn.
Look at page #44 of your manual. It says use the same House and Unit Codes. A direct conflict with what the X10 Kbase says.
The SC1200 sends the actual addresses only. So an unused unit code will not work.
Please try an unused unit code and let us know if the siren ever goes off on a panic or alarm.
-
well' then my old PH508's may not work with new SC1200 Console.
-
Yours are not that old, but maybe in the time period when they first did the redesign.
My old 2002 and 2005 are fine with the SC1200. No burps when armed and sirens are OK.
Now my 2010 ones also have no burps when armed, but the siren sounds for four cycles then stop for ten seconds and start the whole four cycles ten pause all over again.
You can try an unused Unit Code to double check if it would work or not.
-
will try another SC1200 to see how it goes this may take a week or two for another console.
-
Do you have any other X10 devices? Like a coupler repeater we forgot to ask about?
-
Just went back over your posts.
How did you make it go into the strange sound making?
Brian
When I was doing the earler Powerhorn settings testing and repeatedly triggering the system, I too experienced the "sick cow" sound from the console when triggered and also the entry chime on the console. After a few hours it just went away and now sounds normal. Maybe it just got tired :)
-
Thanks for the information.
So maybe it is just a quirk of the system.
I am still wondering why the Powerhorns momentarily sound with an Arm home or away for vlong.
Maybe it is a Powerhorn thing as with the older DS7000 Kit you set the Unit to a unused setting. As it sent the All Lights On, All Units Off commands.
The SC1200 only sends the two Light Code Addresses.
I know different Date Code PH508s act different on my SC1200A. Unfortunately I don't have any in the 08G31 to 09A03 date code range, vlong has, to try.
My 2002-2005 ones actually work OK. My two 2010 units. Sound for four cycles then stop for ten seconds then start again.
-

no other x10 device using with this console.
-
OK. I just wanted to cover more bases.
If you do get another SC1200. All of us would be interested if the Powerhorns act differently.
-
Brian H,
I will update once i get the new unit maybe in one week.
but i still think PH508 with older date code will not work with new console.
-
Well I can tell you my two 2010 ones are not 100% correct with my SC1200A.
Workable but not like they should be, or how I would expect them to act.
My real early 2002-2005 ones seem to be 100% OK with the SC1200A in its installed location, and all of them acted slightly different when the console was on my kitchen table during first tests.
If your second SC1200A does basically the same thing. Then we know there are PH508s. With in some date codes that sound briefly when the console is armed away or home.
-
will keep you inform to see how the thing act.
-
OK but I fear it will be the same.
Another user is reporting the exact same problem in the Security Problems and Troubleshooting Area.
If your second one does not, then we know it is a very close timing thing.
-
I will get the new Unit on 3-12-11

Hay Brian great job helping out! Say I have a contact at x10 a vice president and I plan on emailing him and informing him of these problems. If I get a response I'll post what he has to say.
So if you have a specific question let me know and I'll ask him that to. I'm thinking the powerhorns and the limited number of lights that can be flashed should be addressed. Let me know if I should add anything else.
Tom j.
-
You may tell him. Many of these things where also in the Radio Shack 49-1000MC console they made in late 2004 and never corrected.
If you do a search of the forums for 49-1000.
Reverse order if you want to see the older ones first.
Powerhorns where reported way back then.
The SC1200 is not updated much from the older 49-1000MC.

Anything else you want addressed how about the limited amount of lights that will flash limited to two per address. And if anyone else has concerns let me know.

Well if they went back to All Lights On and All Units Off like the older console.
Powerhorn problems would go away. Including brief beep when armed that some are finding.
IMHO. Your concerns are going to fall on Deaf Ears and nothing is going to change.
RS owners all cried about the samethings. The SC1200A where they had a chance to fix things. Didn't happen.
-
Brian H,
Got the new Unit SC1200 Today had the same problem so the problem has to be PH508.
-
I am sure it is a combination. The SC1200 sends out on and off commands to the Light Codes.
Some PH508s react too fast and make the noise. If the SC1200 sent out the All Lights On and All Units off like the old console. You could set the PH508 to an unused unit code. It would not sound on an arm but still sound with the All Lights On All Units Off cycles.
-
Maybe this has already been mentioned but for you PowerHorn lovers, you could use a PowerFlash to activate PowerHorns. Just need to find a trigger source in the SC1200, and kiss your warrenties good bye. I bet Brian H already has a PowerFlash trigger pinpointed.

If i set to different Unit code will get no sound. SC1200 and PH508 must set to the same HouseCode and the same Unit Code to have sound but the only problem was i have listen to the friken sound for the moment when press Arm home or Arm away. Now i have no idea
-
Yes I remember your problem.
My older 2002-2005 PH508 units do not sound when armed and trigger properly with a SC1200 alarm.
Both of my 2010 PH508 units also do not sound when the SC1200 is armed but during an alarm they are not 100% of what I expected. Four hi low siren sounds then a ten second pause. Then four more hi low sounds and another ten second pause.
Your 08G13 and 09A03 ones seem to be triggering with a single on off command when armed.
How would a new PH508 work for you as an option? Not to costly from some of the online dealers.
I don't honestly know if it would be a solution for you. As it seems signal timing is very critical when a SC1200 and PH508 are used together.
-
dave w; If we triggered a Powerflash to send the All Units Off All Lights On command cycles. I was thinking we could have signal collisions.
The Powerflash is not polite and I am almost 100% sure the SC1200 isn't. If it is still sending the On Off cycles to the Light Codes and the Powerflash the All Lights On All Units Off commands at the same time.

Brian seeing that you have first hand experience with the powerhorns how would you describe the problems that way I can just past it in the email and I won't miss anything. I'll post the reply, Thanks!!

See attached.
The problems in my rough tests show hardware version seems to play a role in how they act.
I don't have any of the Powerhorns that are reported to sound briefly when the console is armed home or away.
The ones that could get very annoying fast. ::)
I also don't have any that didn't trigger at all, but others here are having no trigger problems.

Ok I can include that in the email but let me get this straight there appears to be some compatibility issues. And are you saying that with some people the large power horns works perfectly? you said some people are having no trigger problems. Just not sure I understand and I want to make sure before I send this email off. Thanks

All depends on the Powerhorns Date Code. Things have changed over the years.
My real old ones are 100% OK.
Both my 2010 models trigger but are not a constant the normal high low sound. They sound four cycles then stop for ten seconds. Then again four more high low tones. Then stop again for ten seconds.
We have two threads here where arming the console causes the Powerhorn to sound and it should NOT sound on an arm action.
We also have a thread where even when set to a light code as required. They never get a siren sound, but I had then send the codes with the keypad and the Powerhorn DID sound!

well' now how do we know witch PowerHorn work %100 with new SC1200 :(

This might work for me then whats the date code on the really old ones you said work perfectly. I have 4 that are fairly old. And did someone say the MS10 have difficulty communicating with the new console, thanks for the clarification!

-
Yes rhea did say in one of the threads. The DS10As work more slowly and I believe less distance. He also said he was getting a momentary sound when arming in one thread and insinuated was OK in another one? ???
Sorry for the slightly different results but it look like exactly where in my house the console is and where the Powerhorn is changes things slightly. Retested this morning.
None of the PH508's I have work exactly like they do with the PS561 console in the DS7000 Kit. I would think the one second momentary pause on the older ones and louder sound. Would be acceptable to most users.
Tried them on both phases of the house. XTB-IIR running. Using two outlets. One on the same circuit as the console and the other outlet on the opposite phase. Results didn't vary enough to note.
Date Codes: 02H35, 05C10 and 05B09 {all older design. MUCH Louder than new ones} Took about ten seconds to trigger. Paused for 1 second then continuous high low tones.
Date Codes: 10L52 {PH508}, 10F25 {PSH01} {new design not nearly as loud as the old design} Took eight seconds to trigger. Four sets of high low tones. Pause ten seconds. Four more high low tones sets. Pause again for ten seconds.
I don't have any in the Date Code range. 08G31 and 09A03 vlong has or 07L52 rhea has. That where reported to sound on an arm function and none of mine sounded on an Arm.

OK I got it but Jeez, why do you think the reduction in range with the MS10a's?? :(
Tom j.
-
Newer design.
Closer to ideal RF frequency as it uses a saw device for frequency determination.
Antenna orientation comes to mind. The SC1200 has its wrapped around the case so it is horizontal unless on a wall and the older console has a nice metal external vertical antenna. I would like to see a DS12A and DS10A tested with an older console.
As for the delay in tripping. Well it would not be hard to have one model set to one detect and the other one two detects needed to send an alarm.

Let me make sure I understand is the range on the MS10a with the newer SC120 shorter then what you would get with the DS7000 console??

Well I don't know, but have seen other reporting poorer results with a DS10A over a DS12A.
I have been using DS10As along with a PS561 earlier.
When I received my first SC1200 kit, I just registered the existing DS10As.
Many of the DS10As started failing at random: either signaling a low battery or a door open, but only to the SC12A, the PS561 which is still in service did not detect a problem.
I suspected a range problem, so I installed a DS12A with an external switch, farther away than the DS10As, the DS12A never failed.
I exchanged the SC12A for another, and relocated it to a more central location (the house is a 20 x 35 rectangle on 3 floors). The SC12A still see problems with the DS10As, none with the DS12A. The PS561 has no problem with either.
One thing I noticed, when the DS10As fail, I can "revive" them by pushing the "Test" button. I suspect the nature of the signal is different than on an open/close than with the "Test" button. All my door/window sensors are set to a short delay".
Eventually, I plan to migrate to all new sensors.
-
Brian,
I received your PH508 it works.
thanks million :)

You are welcome.
The fact that the Date Code 2005 works for you. Gives me more information on how different versions are working.
When yours gets here. I will have another clue.

I really want to get at least one more from x10 but not knowing for the fact that it will work like your or not.
-
The new ones may not work like the 2005 one I exchanged with you.
I have a X10 PH508 Date Code 10L52 and an X10Pro PSH01 Date Code 10F25. Both bought in the last month from independent X10 dealers on EBay. At a very reasonable cost.
Both of them didn't make any noise when the console was armed away or home.
They did not work exactly the same when an alarm was set off.
They would take about ten seconds to sound.
Then sound for four High/Low tone cycles.
Stop for about ten seconds.
Then sound again for four High/Low Tone cycles.
Alternated between four sound cycles and ten second pause as long as the alarm was sounding.
Now if X10 has done things in the 2011 Date Codes. I can not say what a brand new one would do.
-
The new ones may not work like the 2005 one I exchanged with you.
I have a X10 PH508 Date Code 10L52 and an X10Pro PSH01 Date Code 10F25. Both bought in the last month from independent X10 dealers on EBay. At a very reasonable cost.
Both of them didn't make any noise when the console was armed away or home.
They did not work exactly the same when an alarm was set off.
They would take about ten seconds to sound.

well' looks like it become a door stopper for me then if x10 not try fix the problem.
-
Most folks may find the intermittent sound cycles OK but definitely not ideal.
Guess it is better than sounding with an arm on the console. ;)
-
I agreeded you.
-
Received the Date Code 09A03 PH508 today.
I can verify it does sound two Hi/Low Tone cycles with a SC1200 console "Arm Home" Function and Arm with the KR32 KeyFob Function.
-
so do you think it will be usless with the new console SC1200???
with old console works fine PS561
-
I have not formed an opinion on it when used with a SC1200A.
More tests will be done.
All it takes is one On/Off cycle or All Lights On/All Units Off to trigger it. Older ones need four or more one second cycles to trigger them. The newer 2010 ones also needed more cycles.
-
How is the volume level? As loud as the old ones?
-
Well I don't have a sound level meter, but my ancient ears say all the new design one are not as loud.
I know the 2009 and 2010 ones I have are not as loud.
Maybe vlong can give us his thoughts on the 2005 I swapped to him for the 2009.
-
yep, I noticed that 2005 was abit louder then 2009.
-
I am not surprised the 2005 I sent was louder. The older ones have a real audio output stage with a transformer driving the sounders. The new ones look like a pair of push pull transistors driving the sounder directly. I saw no audio output transformer in any of my 2009 or 2010 units.
I played with the 2009 today and compared it to both of the 2010 ones.
Both 2010 units have a firmware sticker of. P11021C PCB:042010=12014B
2009 unit firmware sticker P11021B PCB:042010=12014A
Can't read the values on the surface mounted resistors and caps so I don't know if there are different components between them.

Yeah, general purpose transisters are cheaper than transformers. I think those piezo alarms are high impedance, I wonder if the transformer acted as a step up xformer.
-
I made an error. :'
I was thinking of the SH10A that has the output transformer.
I just looked at an old PH508 and it didn't have any transformers for sound output.
It does have a plus and minus 30 volt power supply with reference to common.
-
Yeah, but if the new horns are not as loud as the old horns, you can bet X10 is trying to save a penny somewhere. :'
-
Well I am going to try a rough sound test.
No Sound Meter just compare with a scope. Signal from a computer style microphone with a new and old one.

Test of PH508 audio levels.
Altec Lansing ABM-100 Stereo Computer Microphone.
Heathkit IO-4540 Scope.
1X Probe.
Breadboard bias circuit for microphone. Using 2 AA batteries and 2.2K resistors.
Old 02H35 Hi Tone: .275V PP
Low Tone: .200V PP
New 09A03 Hi Tone: .125V PP
Low Tone: .100V PP
New 10F25 Hi Tone: .075V PP
Low Tone: .100V PP
Side note:
The XTB-IIRs signal was seen during triggering.
On the scope trace. Must have been radiating from the PH508s power transformer.

looks like the older unit louder then new one not sure why they keep on changing.
-
Many of the X10 modules are slowly being revised to use more modern components.
Many of the components in the older ones are obsolete or almost impassible to find.
The redesign with different parts changed things.
