What about a time delay "silence" circuit of some sort, whereby hitting a "silence" button will drop out the entire circuit for a minute or 2 then reset itself and power the alarms back up, providing of course they are not battery back-up. Could even incorporate an indicator and a smaller much quieter piezo buzzer that will sound during the duration of the "silence" period.
