EAX-300 door propped alarm

Alert security when there is a door propped open with Detex Corp.’s battery-powered door propped alarm (EAX-300). The units require no electrical connection and can be field-set for door-open times ranging from one second to two minutes, with a 15-second default. A 100-decibel alarm sounds, then silences when the door is closed so there is no waiting for a key-holder to arrive. A 9-volt battery with low battery/LED alert powers the alarm.
