NAPCO GEM-P800 has to be reset after each usage?

Nope. No batteries. Four wires - a 12v pair and a normally closed contacts pair.
I'm suspicious of the sensor since I have another one of these sensors in another room and it works fine.
Is there any place online where I can buy a replacement IR sensor?

The system is 10 years old and I don't think any of the sensors other than the smoke detectors have batteries. I don't have the original parts list; so, I don't know the model number of the IR sensor. I suspect it is powered by the system (?) and is not wireless, as I stated above. The part number I listed above is the only one I could find online that seemed close to what I have.

Another seemingly strange occurence: If I arm and disarm after reseting the system, all works OK. I only get the zone 5 beeper after I have armed and been away from the house for an hour or two and then come home and disarm.

I will check it for a battery just to be sure.

So the trouble light is on and it bleeps at you.
Kind of makes me think its trying to tell you something is wrong with zone 5.
Got the manual?
Try replacing the battery in the detector on zone 5 you might be surprised at the results.
