Want to interface my DS7000 alarm with Smoke Detectors
« on: November 08, 2004, 11:44:15 AM »

I have a smoke detector (Frynetics Inc,
Lifesaver Model 1275) in every room of the
house.  These detectors are connected
together on a 3 wire set up, so that if one
alarms, they will all alarm.  The alarm is
so loud that no one could stay in the house
for more than a minute without ear
protection.

I would like to interface it with my X10
Alarm System.  If my X10 alarm system goes
off, I want it to set off my smoke detector
system.

Has anyone done this?  If so, I would
appeciate the info and diagrams as to how
you did it.  Not sure if I need to break
the third wire or bring in 120 volts into
the third wire when the X10 alarm goes off.

Any info would be appeciated.

Are these smoke detectors communicating with
each other via low voltage, or 120 volts? I
think I know a way to do what you're wanting
to do, but I need to know more about the
voltage/communication.

OK, checked it out.  The smoke detectors (
Frynetics Model 1275) are all fed by a 3
wire system from one 120 V AC supply on the
blk/wh wires.  The red wire is also
connected to all the red wires on each
detector.  Each unit has a 9 VDC battery in
it for back-up power.  When one unit
alarms, it sends 9 VDC between the red and
white wire.  So it appears I need a dry
contact picked up by the X10 system and
feed it with a 9 V battery.  Then when the
X10 alarm goes off, this dry contact module
needs to pick-up and set all of the smoke
detectors off.

So, I guess I got it figured out.  All I
need it the part number for an X10 unit
with a dry contact to feed my 9 V battery
to.  Anyone know that part number?

Sure. I was thinking it was something like
that...
You'll need a 'POWERFLASH INTERFACE' (PSC01)
This take a low-voltage and turns it into an
X-10 powerline command, so you could hook it
into the low-voltage loop and then when the
smoke detectors go-offm they'll trip this
thing and it will send an X-10 command down
the line. Seems to be a real neat unit. I
found it on the 'Pro' site, so try this link
and see if it will take you there. If not,
tell a salesperson that this is what you
need.

I hope this helps.

Oops. I've got it backwards! I thought you
wanted the smoke detectors to initiate X-10
commands in the event of smoke, not make
them go off if your security system trips.
In that case, I believe you'll need
the 'UNIVERSAL MODULE' (PUM01). This takes
an X-10 command and trips a dry-contact to
control a low-voltage device. I guess you
could address it to the address that is
supposed to flash the lights and then it
will set-off the smoke detectors for you.

Thanks Ken,
I think the UM506 or Pro PUM01 is the
module I am looking for.  I think the are
both the same module, just different
numbers.

The other Powerflash Interface Module
(PSC01 or PF284) looks also interesting.
Might want to use it also to enhance my
system.

Thanks for the info.
