Visonic Wireless Siren

[stuart1875]

Hi was wondering if anyone could help, I've just installed my first visonic powermax complete intruder system and I have a problem with the wireless siren. What seems to happen is I enrol the siren using the selftest button and it operates normally then after a couple of days the siren doesn't sound under an alarm condition and seems to totally drop of the system. I'm now wondering if it's a dud battery or a possible pcb fault. I've tried using the diagnostic function to check and keep getting the (not ok) message and I've also measured the battery and it seems fine but I'm not sure if the draw is dragging it down once connected. If anyone can help it would be much appreciated.

WHat the signal strength to the bell. Could be a range issue. Might be worth temp fitting it by the panel to see how it performs. If all is ok you will need to relocate the bell.

COuld be battery but as they are monitored if expect a battery fault rather than it going missing.

Thanks for the comments Visonic want to look at the board, had a quick look myself and one of the ic's looks a bit smokey. Going to wait and see what they say.
