Our alarm has taken to sounding with a 'Panic' notification from time-to-time despite there being no panic button installed. It has also alarmed with both zones indicated without any apparent reason: the last time it did this it took a long time for it to settle once the exit door had been closed, but I waited and it did settle.
The panel is a Scantronic 9448 and the only change has been the recent replacement of the bell box with a Honeywell AG6 sounder and strobe (the panel wasn't originally wired with a strobe output so, as the instructions suggest, 'ST-' was linked to' SW-').
Anyone got any thoughts on what might be going on? I don't want to upset the neighbours with false alarms.
