SDC’s 490 series emergency release stations provide immediate unlocking of perimeter doors or interior doors that are equipped with fail-safe electric locks. The 490’s built in alarm may be used as a local door annunciator.
Specifically designed for emergency door release, 490 series emergency release stations may influence the approval of an electric locking system.
The 491 model may be preferred over a pull station since greater commitment is required to break the glass.
