Detex Corp. of New Braunfels, Texas, releases the EAX-300, a battery-powered door-propped alarm that sounds an alert when a secured door is propped open.
Powered by a 9V battery, the alarm can be field-set for door-open times ranging from one second to two minutes, with a 15-second default. A 100-decibel alarm alerts users, then silences when the door closes, eliminating the need to wait for a key-holder to arrive at the scene.
A patented plastic template indicates alignment with the internal magnetic door contact for accurate installation, according to the company.
