How it works
Four steps at the door
Push
Someone pushes the exit device or door.
Alarm & countdown
A local alarm sounds and the countdown starts, with a voice message on SDC ExitCheck.
Door releases
After 15 seconds (30 where approved) the door unlocks.
Staff reset
The lock is reset by key or keypad.
Life safety first: SDC delayed egress locks release immediately in an emergency, and a signal from the fire alarm system releases the lock. SDC notes that all installations must be approved by the local Authority Having Jurisdiction.
