The Ultimate Failsafe for Access Control Systems
In any commercial building or secure facility, safety must always come first. If an access control panel, RFID reader, or exit button malfunctions during a power surge or emergency, personnel can become trapped inside. The Resettable Emergency Door Release acts as a direct, hardwired override. By pressing the panel, it physically breaks the electrical loop to your door locks, instantly releasing magnetic locks or electric drop bolts to ensure a safe and immediate exit.
Reusable Design Saves Time and Money
Traditional "break glass" call points require you to purchase and install replacement glass every time they are triggered or accidentally bumped. This modern emergency switch features a resettable plastic mechanism. Once activated, the front plate drops down to cut the circuit. To restore the system, simply use the included reset key to pop the plate back into its original position. It is 100% reusable, saving maintenance time and operational costs.
Fireproof Construction with Protective Cover
Built to meet strict safety requests, the entire housing is constructed from premium fireproof materials with an elegant sandblast finish. To prevent false alarms or accidental triggers by passing carts or personnel, this model comes equipped with a clear hinged protective cover. Users must lift the cover before pressing the emergency release, adding a crucial layer of intentionality to the activation process.
💡 Pro Tip from Our Technicians
"Wiring an emergency release correctly is critical for life safety. If you are using a fail-safe lock (like a standard magnetic lock that requires power to stay locked), you must wire this switch in series using the COM (Common) and NC (Normally Closed) terminals. When pressed, it breaks the circuit, dropping power to the lock. If you are building a custom access control system and aren't sure how to wire this into your power supply controller, drop by our Sham Shui Po store! Our team at Sun Cheong Computer Co. Ltd. will map out the exact wiring diagram for you on the spot."

FAQ Section
FAQ Section
- How do I reset the button after it has been pressed?Unlike traditional break-glass models, this resettable switch comes with a special reset key. Simply insert the key into the designated slot on the unit, and the front faceplate will pop back up into its original, armed position, restoring the electrical circuit.
- Does this button need its own power supply to work?No, this emergency release button is a passive mechanical switch. It does not require its own power source. It acts as a bridge (or a break) in the power wire that goes from your access control power supply to your electric lock.
- Can I use this with a 12V or 24V magnetic lock?Yes, absolutely. The internal microswitch is rated to handle a maximum of 3A at 36VDC. This makes it perfectly safe and compatible with standard 12VDC and 24VDC magnetic locks and electric strikes.
