I have a 20 year old security system that includes 3 smoke alarms, one is
the ion type the other two are optical sensors.
They all blink at regular intervals, seemingly indicating that all is well.
Or is it?
I suspect that the blinking lights only indicate that the circuits are
working properly. But, does that mean they will actually sound off in the
presence of fire/smoke??
How can I be sure that I can rely on them when there is a fire or smoke?
Just what does the blinking LED mean??
While googling, I noticed that some people recommend new smoke detectors
every ten years or so. Is there any rational need for this, or is it just an
urban myth? Many of my electronic components have lasted more than 20 years.
Why should smoke detectors conk out after ten years?
Its a myth to replace them by time, my security co wanted me to
replace them from a false alarm , when a spider or dust set a false
alarm, you gotta know techs make a kickback on selling stuff. Mine can
be tested with a magnet, but make smoke and see what happens. A
cigarette, a candle, a metal can with something small burning might do
Companies make their most money on new instals, and they all are
liars, on commission. A good system will last till an electrical part
failure or a sensor is crudded up with grease, do your own tests
first, my co wanted near 200 $ US a sensor, I said Good By for today,
I will check it out. That happened several times in the last 10 years
with Honeywell and my 3 false alarms.
So do your own test, its like your New car auto dealer selling you
1000$ worth of uneeded maintenance, which I have seen [ many times] ,
and they tried to pull on me.
Mine is hard wire, Honeywell, monitored, twice techs were out for
dust or spiders setting off false alarms and wanted 1000$ for new
sensors for what still works today. Gee I guess I gotta do a 08 check
over soon, Thanks for reminding me pal. But dont get suckered, test em
your self. Learn your set up. So you dont get suckered.
