So alarm in the lounge was bleeping so I duly changed the battery (it is electric and battery). Still it kept bleeping intermittently. Went on the internet and the advice was to turn off the electricity with the battery out and then turn on electric and put battery back in. Did that 3 times. It seems alarm is past it's best so have ordered a new one online. Until the replacement one arrives, how can I stop the old one bleeping. Have removed alarm with battery and electric connection. Help! Noise is driving me slowly mad!
