We have inherited this alarm system and were left an alarm code although I am not familiar with the operation.
Today, during the gales, we had a power surge and the alarm went off.
Despite entering the code we were given, the alarm continued to sound for about 5 minutes and then went off of its own accord. However, the external light continues to flash.
I have downloaded the user manual but the panel responses dont seem to match what should be happening.
If I enter our code (which I assume to be correct), all I get is a single buzz from the panel. It is the LED type and the power LED is on but no other LED is lit. I have tried to reset it with no joy... the external strobe light continues to flash.
Does anyone have any ideas, however obscure?
