The SDC 491 “Break Glass” Emergency Door Release is
ideal for immediate unlocking of perimeter doors or interior
work area doors that are equipped with fail-safe electric
locks.
The SDC 491 is specifically designed for emergency door
release and may influence the approval of an electric
locking system.
This type of Emergency Door Release may be preferred

break the glass.
