Hi All,
I’ve finally gotten around to wiring out Honeywell Galaxy 20 alarm system. The Bell Boxes have been on the wall for about 3 yrs and were installed by our electrician. I decided it’ll be worth testing the bell boxes to confirm they are working as expected. The rear box is working, connected to 12v psu I get slow alternate flashing LEDs. I can then operate the strobe and sounder by grounding the appropriate wire. The front bell box however is not working. When connected to 12volts the sounder goes off for ~5secs and the left hand led flashes. Looking at the instructions this indicates a tamper fault. However if I measure the resistance between the tamper wire and 0v wire I get ~2.5ohm, which is almost identical to the rear box. Do you think this is actually a fault or could it be because the onboard battery needs charging? Unfortunately I do have a set of ladders to reach the bell box.
Any advise great fully received
Nick
