What is Emergency Door Release With 2 Keys DPDT (2NO/2NC/2COM)

• 2 Keys: Two dedicated keys are required for operation (design varies by model: some need both keys to unlock, others allow either key for redundancy), which prevents unauthorized or accidental triggering of the emergency release function.
• DPDT (2NO/2NC/2COM): This refers to its electrical contact configuration:
• 2COM (2 Common Terminals): The core connection points for circuit current.
• 2NO (2 Normally Open Terminals): Circuits are open under normal conditions and close only when the emergency release is activated (to trigger related signals, e.g., door opening alerts).
• 2NC (2 Normally Closed Terminals): Circuits are closed under normal conditions and open when activated (to cut off power to related devices, e.g., door locks).

Main Application Scenarios

1. Commercial & Office Buildings: Fire exits, stairwell doors, or restricted access floors (ensures safe evacuation during emergencies while preventing daily unauthorized entry).
2. Industrial Facilities: Factory workshops, warehouses, or equipment rooms (matches with automatic door units or heavy-duty access locks, enabling emergency evacuation when power is off or systems fail).
3. High-security Venues: Banks, data centers, jewelry stores, or government buildings (dual-key design adds a security layer to avoid deliberate tampering with emergency exits).
4. Public Places: Hospitals, schools, or shopping malls (complies with fire safety codes, ensuring quick door release in emergencies without compromising daily access management).
