Outlet-Box-Mount Key Switches
Reset fire panels, or open electromagnetic locks, electric strikes, and automatic door openers. These switches require a key to turn circuits on or off, limiting access and preventing accidental activation. The lock is not included; use a 1 1/4" long mortise lock with a standard cam.
Switches with a delayed start timer allow personnel to reach a door before it opens.
