Detex EAX300GRY Surface Mount Battery Powered 100DB Door Prop Alarm with Internal Magnetic Door Contacts and Back Box Gray Finish

The Detex EAX300GRY is a battery-powered door prop alarm that monitors unauthorized door propping in commercial buildings. This surface-mount unit installs on interior doors where propping creates energy loss or security concerns. The 100dB alarm activates when doors remain open beyond the preset time delay, helping facility managers maintain proper door closure for HVAC efficiency and perimeter control.

The EAX-300 series uses internal magnetic door contacts with intelligent sensing that automatically determines door handing during installation. The tampered-resistant housing mounts on either the door or wall frame. A patented plastic template ensures accurate alignment of the magnetic contact system. The alarm silences immediately when the door closes, eliminating wait times for manual reset.

Door prop alarms support NFPA 101 egress requirements by ensuring exit doors remain unobstructed while preventing unauthorized propping that compromises building security. These devices work within IBC Chapter 10 means of egress provisions that require doors to operate properly during emergency evacuation.
