Protechtor Lp Gas Detector Troubleshooting
No 'end of life' circuitry, it's just the normal life expectancy of the sensors. But that's normally the maximum expected life span, they can and do fail sooner. The gas detectors we carry on our fire trucks normally last a year or two before we have to change sensors (at $150 a pop).
First Alert CO detectors are now advertising a 7 year life expectancy. Dust, insects, household sprays, and other factors can shorten the life of the sensor. John: The manual I posted a link to ( ) shows a specific alarm light code for 'end of life'. Either the sensor output is screwy at that time, or there is a timer. With the new supercapacitors and ultra low current consumption circuitry, such a timer could run 5 years disconnected from the 12 volt supply.
