ADT 5890 PIR Motion Strange Behaviour

["Bob. Wells" <rwells118@xxxxxxxxxxxxx>]

Hello All,

    I have two Ademco 5890 PIR Motion Detectors (non PI). I have a Vista 20P
panel with a 5882 ENH receiver. One of the 5890's works normally as expected
with the shorting clip in both test and normal positions. The other works
correctly ONLY in the test mode. In the normal mode it will not signal the
receiver (no red or green flashing LED) and set off the alarm. Both 5890's
have pulse counts set to off. Both units have brand new Duracell 123 in
them. I would rather not have the LED light on the 5890thinking this might
waste battery life and also alert a potential intruder(not sure if that is a
good or bad point). I could just snip a lead to the LED but don't know how
this might affect the electronics. I'd rather make sure I am not overlooking
something simple first. Any ideas would be greatly appreciated.

Thank You,
Bob
