Alarm Lock 715X28X88X48 Alarm Bar

48" bar alarm system featuring two alarm modes: continuous or 2 minute auto shutdown. Non-handed, delayed egress, electronic exit door locking system. Arming is accomplished by actuating the deadbolt using a 1-1/8rim 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.
