Say Dennis seems like you have a defective <BR>unit plan and simple, I had a similar <BR>problem with a unit that was almost a year <BR>old I replaced 2 times for various problems <BR>and I haven't had any problems since, that's <BR>going on two years ago. Yep you could say <BR>some of x10 stuff is junk but they should <BR>really have better quality control for <BR>something as important as an alarm system. <BR>If someone had broke in on the day it went <BR>out they could have cleaned me out. <BR>Tcj <BR>

EXTERNAL ALARM FOR 49-1000
PART LIST
all from Radio Shack
1. Diodes 5 1N4003 4 is for
bridge, 1 is to put across relay
coil(protects FET from
Voltage spikes)
2 . Capacitor 2 .1@50v 1 across bridge
output and 1 across fet gate to source
3 Trimpot 1 20k ohm Radio Shack
may have this in mixed assortment bag.
4. MOSFET 1 IF510 Radio Shack has this.
5. Relay 1 12v dc relay Radio Shack
6 12 Pwr Sup 1 12v dc power supply with
at least 500MA out ( I used 1AMP)
7. Siren 1 Any 12vdc siren
within current limits of pwr sup& relay
ASSEMBLY
1.Open 49-1000 and solder a pair of 24 awg
wires to piezo sounder in
Parallel with the existing ones. Route wire
pair thru one of many holes in back cover
then replace back cover on 49-1000.
Use a piece of perf board to assemble parts on.
2. Make a bridge rectifier with 4 of the
diodes(if not sure how, get a tech book)
3. Connect the 2 wires from alarm to the ac
in on the bridge rectifier.
4. Connect a .1 capacitor across + and –
output of bridge
5. Connect the 20k trimpot across + and –
output of bridge also(cw &ccw)
6. Connect one end of a 1k resistor to wiper
of trimpot.
7. Before fet is put in circuit, put a
voltmeter plus lead on wiper of pot and - lead
To – bridge. Trigger the alarm and adjust
the output to 15vdc at the pot wiper.Turn
alarm off and Continue assembly
8.Connect open end of 1k resistor to gate of
fet.
9. Connect one end of a .1 cap to gate of fet
and other end to minus of bridge.
10 Connect source lead of fet to minus of
bridge also.
11. Connect a diode across the coil of the relay.
12. Connect the anode side of the relay coil
and diode to the drain of the fet.
13. Connect cathode(end with band) side of
the relay coil and diode to the +12 volt
Power Supply
14. Connect minus side of 12 power supply to
minus of bridge.
15. Also connect +12 volt to a contact on
relay that is normally open.
16. Connect the wiper for that contact to
the plus on the external siren
17. Now ground the minus side of the siren
back to the bridge minus.
Assembly is now complete

Correction to Parts list
Mosfet is IR510 not IF510
-
Dennis be sure to return your defective unit
asap it has a 1 year warrenty. Hopefully the
second one will do the trick.

Is there any way I can get Robert D to draw a
schematic of the project he describes
(External Alarm RS 40-1000)?
Some of us simpke folks would like to have it
but don't know enough electronics to
understand what he is doing.
-
I would draw a schematic but don't know how to
post it on this site
-
Robert D.
My email address is icebluemale at
hotmail.com. I would most definately like a
schematic. Also...Does the external siren
beep when you arm and disarm the system as
does the console alarm (this would be a plus
for me)?
-
No, the only time you hear the external alarm
is when there is an actual alarm.
-
I saw you guys talking about the external
siren... Is there finally a siren you can
use with this? or no?
-
Robert D
Send me a copy of the schematic if you have
one drawn up.
My e-mail address is :
bill.salisbury@us.army.mil
I think I can build the project if I can see
what it looks like.
Thanks
Bill salisbury

Just want to keep this thread alive.

Okay I am alittle upset myself Seems how I
ordered 2 PH508's today an hour before I
found this website. I to Like my RS system.
So I will ask my fellow electroinc tech's.
Has any body tried to hard wire the Siren
on, and then plug it into a lamp module????
Does anyone have a schematic so I could
try???

I'm sure everyone knows about the GE SIMON 3
Security System, but if you don't, check it
out on www.homesecuritystore.com It's a
really good alarm system, and it uses the x-
10 powerhorns. It doesnt have range
problems, or any other types of problems
like my RS system has... I have ordered it,
and eventhough it costs about 500 dollars
after buying all the additional sensors and
wut not, it is still very worth it.
-
As a tip for people with range problems
(problem zones) I have extended the internal
antenna with a piece of wire routed out the
back through one of the exisiting holes.
Works great......
-
I have herd about doing that from resolving
range problems, but I still think its too
much work ... lol
-
Rob; I have not seen a full schematic. I
have seen modification information on adding
the external relay to it in the PC board
area where the parts are missing. I have
limited schematics in hand scratch for the
power supply used to drive the relay.
Strange one as the positive side is around
24 volts while the transistor that pulls the
other side of the realy low connects to a -
15 volt regulator.
I still have not found a relay thet matches
the hole pattern and has the proper pinout.
Tht Shack sells one that fits but has the
incorrect pinouts?
www.pigselectronics.com
In their tech tips has this mod and one to
cut the ON OFF cycles needed to trip it.
-
Thanks Brian H. That looks like a good
website. I would much rather mess with the
horn and leave the keypad alone. With that
information I will have to see how the horns
react when they get here. You could hard
wire the 7volts and make the alarm run
continous(controling them with a light
module), if changing the capacitor value
dosent work...Now that knot in my stomach is
starting to go away..
-
I tried a smaller cap as a test. With a remote control you can send the on off cycle of address [house and unit] or all lights on all units off on the house code. I got a value of one cycle and the RS unit made it chirp. Problem maybe given earlier in thread. Is the RS sends a on off code on two in line addresses. My guess is the second address is enough to disrupt the cycle count and it doesn't trigger. The PH508 has a powertransformer in it unlike most X10 line derived modules. A dimmer module with the triac output may not work well with a power transformer; and we know a appliance type doesn't respond to the all lights on commands, that a DS7000 sends but would on the on off address sent by the RS Console. Downside of an appliance module is the small sensing current always there that keeps some low voltage supplies on slightly. Mods aviable for those too.

Brian H. ,
Have you ever put a 75watt light bulb in
series? Yes I said series. In my TV repair
days you would put a light bulb in series
with a tv that had a fuse blowing problem
(short). While the short exisited in the tv
the light bulb would glow bright, but not
allow the fuse to blow. When you removed the
short(you get my drift). This would add
alittle resistance to the circuit so the
module would act properly...
-
OH yes the light bulb trick. I have also got
my fingers too close to the Horizontal
output tube [gave my age didn't I?}. I also
did two way radio repairs for a time.
Nothing like a 125 watt transmitter being
keyed by the owner while you are fixing the
antenna!
-
I still havent received my sirens yet, but
got to play with the lamp module some. I
didnt realize that it flashed the lights
when you armed it for home. I dont think I
could deal with two 1 second blasts of siren
right before going to bed. So I dont think I
will hard wire them on and plug them into a
lamp module. I think that is why they
designed them not to go off until after a
few cycles. I will have to see how they act
when I get them. I have heard that they dont
work at all too that they only sound for 10
seconds.
-
Unless X10 has changed them. They sound as
long as the on off cycle on the address or
the All Lights; ON All Units Off from the
DS7000 console or 4 minutes if the cycle is
longer than 4 minutes. The RS unit doesn't
send the codes needed to trigger them
properly. With C12 changed I did get the RS
to chirp the sirens. Note they don't sound
like a real siren either. More like a LOUD
two tone warble for the PH508 and more like
Cricket on Speed for the SH10A.
-
how does the siren(ph508) sound normally????
I got mine yesterday and have been playing
with that CAP. There is also a resistor in
parallel with it. Depending on how you set
up your leads, there is 14 volts riding on
that Cap when its pulled down to 7 I can get
a steady loud tone out of the siren. I
assume that when it works normally it pulses
that tone???? Quickly????? It appears that
that cap also plays with on time as well....
-
Normally it has a two tone sound. One when
the ON signal is sent and one when the OFF
is sent. That is after the normal 2-4 cycles
to trip it.
-
This is interesting. When I got home
yesterday I pluged in my siren with a var.
resistor across the Cap. With a lamp module
pluged in next to it to make sure I had a
signal. After playing with the resistance
and getting no results. I went to the output
pin 5 of the 78566. I was getting no control
pulses out of that chip. I might just have
to jumper in the signal from the lamp
controler after all to see what it does..Yes
I love to tinker!!!!
-
that the ph508 and rs49-1000 work together
is false advertising. I can see that I
wasted my money just like many others on
this forum. I think radio shack should
take these back or else we should all file
a complaint against radio shack!!! I
wonder if there is a way we could all do
this together. Mariano
