Out of the blue, my keypad began blinking and beeping at the power light, which indicates "Low battery or blown fuse". I replaced the battery and the keypad fuse but the light still blinked. By accident, I decided to turn off the power and turn it back on and found this would stop the blinking----this seems to be a re-set button. However, exactly every 24 hours, the blinking and beeping re-occurs and I must go through the routine of turning off the power and turning it back on. Any ideas? This is model Z1100.
Sounds like the charging circuit might be shot on the panel, measure voltage across the red and black bettery leads without the battery hooked up, should read between 12.6 and 13.2 (if memory serves correctly), anything in the 2 to 11 volt ranges and the power supply is dead, if the panel reads no voltage then one of your other fuese may be blown (and there is one in line of the + battery lead (again if memory serves correctly).
The Moose panels check the battery every 24 hrs (from power up or last check) so if you turned the panel on at 5 am then around 5 am the next morning it's gonna start beeping as long as it thinks it's got a bad battery.
Hope this helps.
