hi kofi,
Most alarms have a RESET button so that the alarm can be cancelled.

The method I use for false alarms is to have a low level alarm sound for say about 10seconds then the main loud alarm sound after that.
So when I get an alarm I can quickly check whats caused it and RESET it if required.

We would need to see your circuit diagram so that we can advise how to fit a RESET switch...
