The SD-7428-GSEQ allows for a controlled exit from a room protected by an electromagnetic door lock. To exit the room, press the large green button until the built-in buzzer sounds, at which time a programmed pre-exit delay timer begins. After the delay, the door unlocks and stays unlocked. To relock the door, use the included keys to turn the keyswitch.

Features:
* Programmable nuisance delay timer (0~3 seconds) to prevent accidental door unlocking
* Adjustable pre-delay timer (1~30 seconds until the door unlocks)
* 12~24 VDC Operation
* Form C relay outputs for lock relay and remote alarm relay
* Built-in 100dB buzzer
* Fits standard double-gang backbox
* Keyswitch to re-energize door lock
