Timed open door Alarm

    Hi.

    I have been asked to find an off the shelf solution to the scenario below if possible.

    We have a fire exit / loading bay door that keeps being left open.

    Ideally we need an alarm with a variable timer that sounds 2 - 5 minutes after the alarm is triggered by the opening door. Once the door has been closed the alarm needs to be silenced and then automatically reset.

    Most of the alarms I can find need to be reset each time they are triggered. Worse comes to the worse I can make a simple read switch to timer to buzzer but my boss would prefer a pre built solution sadly.

    Any help is very welcome

    The first I found, seems to fit the bill:

    "Door left open alarm" brings up a decent selection on Google

    It certainly does. Your googling skills are much better than mine. Thanks.
