We had a power out in the early hours of the morning-the Cooper 9751 alarm system which was unset gave out a beep warning to say the power was off. I did a reset to stop the internal warning beep. About 3 hours later the external bell went off-I could not reset it as the Keypad indicated no power to it-all I could do was let the battery drain down.
The system was set up that the external bell was turned off. Power came on and now back to normal
Any ideas on how this or why it happened and how to stop the bell from ringing?
