Sdc 423MUL1G Electric Strike Release Timer Exit Device

Product Description

The SDC - SECURITY DOOR CONTROLS 423MUL1G is an electric strike release and timer unit designed for access control and life-safety door hardware applications. It provides timed release functionality, allowing door strikes or locking devices to cycle open for a controlled interval before returning to the secured state. Licensed electricians and access control technicians typically specify and install this device as part of a broader exit or entry control system. The 423MUL1G ships as a single unit and is categorized within exit devices and push button control hardware.

This release and timer device is suited for commercial door openings where timed electric strike operation is required, such as office entry vestibules, stairwell doors, and controlled-access corridors. It integrates into low-voltage access control panels and can support code-compliant egress requirements when paired with the appropriate locking hardware. The finish designation 630 indicates a satin stainless appearance, making it appropriate for exposed hardware applications where aesthetics matter alongside function.
