Question about Home
My alarm monitoring service tells me they are getting multiple sensor error readings from my smoke detectors. This occurs at the same time each morning. I have checked the voltage at the alarm panel where they are wired and it reads 3.7 volts. I checked the voltage at the last detector in the line with the 2k resistor and it measured the same voltage at 3.7 volts. Is this the cause of faulty sensors? They are and are 4years old and are GE model 511c. Any help would be greatly appreciated.
Before I can really try to answer, I would like to know what make/model control panel you have (ex: Honeywell Vista20P), the zone number of the affected smokes, and whether or not you get an indication of a problem on your keypad.

SOURCE: KNOCK SENSOR KEEP GOING OUT
Make sure you are not over torquing it. if you screw it in to much, it will give false readings and if it is not screwed in enough, it will also give false readings.
There's a delicate balance to be known and, if this sensor is over torqued or, not torqued enough, it will malfunction.
