Re: Napco Magnum 900 False Alarms - Fire

["Crash Gordon" <webmaster@xxxxxxxxxxxxxxxxxxxxx>]

I've never had a heat go bad on it's own...usually someone tries to take it
down and breaks the little center thing. In the attic (if I can be convinced
to install one there) I put 200 degree fixed, same in garages, in the house
I put 135 degree rate of rise.

I believe the 900 was 12v like most residential alarms, not 24v. If you
replace the smokes use all the same type, and you'll have to look up the
current draw in alarm for all devices and check the Napco 900 specs and see
where you're at with battery calcs and if the panel can handle all your
devices. If it can't  you can add a secondary aux power supply AND battery
for other devices (not the smokes). Heats don't draw anything so they dont
come into play when making your calculations. But, if you replace the heats
with smokes..do the calcs.

Heats are property saving devices, smokes are life safety...oranges and
tangerines.

It doesn't take as much as you would imagine to set off a heat.
I'd never put a smoke (not a normal one anyway) in an attic.

If the attic heat is a rate of rise...maybe you'd get a false out of
it...kinda doubt it though.

FIRST replace the system battery...my guess is that is part of your problem.
Then clean the smokes for now,,,but they should be replaced, imo.

good luck!

| Looks like my smokes are not AC but rather being fed off the 24v alarm.

| the whole lot since it's been quite a few years.  I did notice that I
| had a heat detector in the attic, round disk about 4" with a smaller
| round thing in the center.  Same one that I have in the kitchen.  The
| other heats are all over the house (including bedrooms) and maybe 1" in
| diameter with a smaller disk in the center.  I never felt comfortable
| with these since it would take a pretty big fire to actually set one
| off.  I had put free standing smoke detectors in all of the bedrooms,
| but would like to add smokes in place of these heats.  Since all of
| this stuff would be powered from the alarm are there calculations
| needed to not overload the 24v that the alarm produces.  What I'm
| meaning to say is that if I just swapped the heats to smokes would that
| overload the alarm?
|
| Also, is it possible that the heat in the attic is toast and when the
| nightly cold air gets to it, could that be setting off the alarm?  Or
| possibly the one in the garage?  Every where else is pretty much heated
| space.
