Detex Corporation, an industry leader in the manufacture of life safety and security door hardware for commercial buildings, offers battery-powered alarm systems that guard against propping doors open. For educational facilities, the system assures that doors left open by mistake or intent won’t defeat the whole security system.
The EAX-300 Door Prop Alarm can be field-set for door prop times ranging from one second to four minutes, with a 15-second default. After the time selected, a 100-decibel alarm alerts staff, then silences when the door is closed so there is no need to wait for a key-holder to arrive. The alarm is powered by a 9-volt battery and has a low battery/LED alert.
