Choosing Door Alarms

Door alarms sound a warning when a door is opened or is held open too long, including Hoyles fire exit and door-held-open alarms and STI multifunction door alarms.

Door held open alarms

The DW304, DW305 and DW306 sound when a door stays open longer than an adjustable delay, set between 30 seconds and 7 minutes. The DW304 and DW306 are typically used on kitchen doors in student accommodation, to stop smoke from cooking drifting into corridors and causing fire alarm activations, and reset as soon as the door is closed.

Frequently asked questions

What is an alarmed door?

An alarmed door is a door fitted with an alarm that sounds when it is opened, often a fire exit kept for emergencies. The alarm deters misuse and warns staff, while the door still opens normally for escape. A sign on the door usually warns that it is alarmed, and a key can silence the alarm for authorised use. The range here includes fire exit door alarms with key control.
