Hello. I have 3 Bosch DS282THS' with a 680ohm terminating resistor hooked to an M1G with FW 4.4.4.
I test the detectors individually and they go into alarm and the monitored voltage on Zone 16 (set with the 2 wire jumper) goes from 12.2v to 9.6v, but the panel doesn't show a fire alarm.
Am I missing something?
I do notice that while my version of the manual says the M1 supports this model of detector with the 680ohm resistor, newer versions of the manul do not list this detector and now call for an 820ohm resistor. So, I did the same test with an 820 EOL and the M1 still doesn't report an alarm. I don't remember what the voltages were though.
I sent this in to Brad via email, but thought the folks here might point me in the right direction in the interim.
Thanks
