Alarm Lock's, Sirenlock model 715 is a non-handed, delayed egress, electronic exit door locking push bar system. Arming is accomplished by actuating the deadbolt using a 1-1/8 rim cylinder (not included). When armed, depressing the push bar will release the deadbolt and sound an immediate alarm, however the deadlatch will prevent the door from opening until the 15-second exit delay has expired. Provisions are made for instant alarmed exit in the event of actual emergencies, such as smoke, fire, power failure, etc., using auxiliary detection equipment. The 715 has a standard aluminum finish and is equipped with a remote interface and alarm indicator relay. A standard 9V alkaline battery is provided and should be installed at all times for proper operation of the unit. An LED on the control box indicates that the unit is armed. Instant 95 dB dual piezo alarm. Easy-to-install, surface mount unit in a standard panic bar deadbolt/deadlatch design. Monitoring output for simultaneous use of CCTV camera, secondary siren, remote monitoring console, etc. Smoke detector input can be used to power existing system or standalone smoke detector(s).
