Greetings, Got a strange one here..8 year old FBII -2P 1 LCD key, I street smart remote keyswitch, 4 combo pir/micro motion detectors, 4 glass breakage detectors, 1 7 amphr battery, 2 sirens
Here's the thing about 10 days ago it started displaying "Low Battery" ..
Ok, the Battery was changed.. 6 hours later it displayed "Low Battery" Again..
Another Battery was installed just in case the first one was faulty.. again 5-6 hours later "Low Battery"..
voltages were DC output 11.50 to 12.00 (ideally should be 12.50 to13.50) current off battery 45 ma.. with AC 150 ma without AC ( about right with the load listed) current off panel 150 ma with or without AC.. ( again about right with the load listed)
Removed all motions, sound, remote keyswitch and sirens.. (only thing on panel was keypad)15 minutes again it displayed "Low Battery"
Being frustrated we removed panel and replaced it with a boxed brand new FBII 2T. (only thing on panel was keypad) Low and behold 15 minutes later it too started beeping "Low Battery"...
No one seems to have an explanation as to what's going on here..
I put it out here wondering if anyone might have some other ideas or suggestions to try and remove this Gremlin .....
((Yes the one common point between both panels is the Keypad))
Problem is I can't figure how the keypad could cause a low battery indication to the panels sensing circuit..
