The SP-J156 Emergency Door Release (also known as a Break Glass / Resettable Emergency Call Point) acts as an essential safety switch for access control systems. Mounted near emergency exit doors, it allows occupants to override electric locks manually in the event of power failures, fires, or system malfunctions.
It typically features a high-impact plastic housing with a clear protective front cover and a trigger mechanism that either uses resettable plastic/glass or a breakable glass element to switch the electrical contact from NC (Normally Closed) to NO (Normally Open), immediately cutting power to the lock.
