I have Firex smoke alarm detectors for the bedrooms. (Apparently put in by
builder.) One went off
sporadically last night. There was no smoke. I noticed that the green
light blinks periodically, but I
saw, or thought I saw, it red periodically. Has anyone out there had a
Guess I will go down to Home Depot and get a new one, since documentation
says to replace every
10 years. The model has been discontinued, and when I tried calling the
company, Invensys, the
phone has been disconnected.
Sure would appreciate any suggestions....
What model is it? The green light usually indicates that AC power is
present. It should be a steady green light.......usually. The red
light usually indicates: 1) of unit self testing ( if flashes every
minute or so).... this is normal, and/or 2) if will flash every second
or so.......with also the audible alarm sounding- this indicates that
the unit is sensing a smoke condition.
If unit beeps every once in a while...............then this indicates
that the internal battery should be replaced. It is usually a 9 volt
I have attached a link to an operators manual for Firex smoke
alarms.............your model, if not there, should be very similiar.
This should help you out. You will have to zoom in to 100% in order to
read it. Hope it helps.
If it went off at a reasonable time, be happy. They always seem to
false alarm at around 3:30 AM. As cheap as they are, you are probably
best off replacing it, and they should all be replaced every 10 years
as someone else noted.
How do you know there was no smoke?
A neighbor had a smoke alarm going off sporadically, so he removed the
detector to get it repaired. I don't know where they repair
detectors, but nonetheless, days or weeks later a fire broke out in
the clock of his stove. Burned out the whole kitchen and smoke damage
elsewhere. Maybe water damage under the kitchen also.
These things are sensitve and will alarm when smoke levels are below
what your nose can sense.
