Honeywell AG6 Fault

[Trav]

With my Optima Compact not active my AG6 Sounder started sounding with gaps. No tamper indication on panel and being aware of dodgy tamper switch I have previously shorted it out as the box is mounted where there are masonry gaps.
Not aware of any power issues..Any help or ideas appreciated.

Tamper switch ...water damage ....power issues ....faulty battery ....ect ect

 

[Trav]

Thanks, no evident water damage anywhere, tamper switch already bypassed/shorted. No known power issues. Do you mean the panel battery, not the AG6 ? The AG6 Instructions mention the sounder being triggered by the backup battery only but panel has power.

What’s the panel output for the bell feed ? Post a picture of the panel pcb ....

 

[Trav]

See attached PCB pic. I've checked panel fuses, all ok. When measuring across bell + & - seeing measure of 0.5V.

 

[sparkymarka]

You measure across bell + and A

 

[Trav]

Measuring across bell + & A getting 12V. All led's on AG6 functioning as they should be. Alarm system has been working all ok until this problem occurred.

Pull the mains fuse ....what happens ?

 

[Trav]

Mains feed isolated, all functioning ok on back up battery, panel, AG6 led's etc. Possible intermittent Bell Box fault ???
