ABSTRACT:
An attachment is provided which can be retrofitted to conventional smoke alarms to make it possible to deactivate the smoke alarm in order to avoid operation of the alarm as a result of intentionally produced smoke which does not represent the threat of fire. The attachment provides a signal that the smoke alarm has been deactivated, the signal serving to remind occupants that the alarm is deactivated. Particularly advantageous embodiments make it simple and easy to replace the battery of the smoke alarm.
