LS042

Key Features and Functions

- Core Role: It ensures the fire door remains closed (to contain fire/smoke) under normal conditions and can be easily opened from the inside for emergency evacuation, complying with fire safety codes.

- Critical Design Traits:

1. Fire Resistance: Constructed with heat-resistant materials (e.g., stainless steel) to withstand high temperatures without failing.

2. Emergency Egress: Equipped with panic bars, push-to-exit mechanisms, or easy-to-operate handles, allowing quick opening from the occupied side without keys.

3. Self-Latching/Closing: Often paired with self-closing devices (like door closers) to automatically shut the door if it’s left ajar, maintaining the fire barrier.

4. Restricted Access (Optional): May have keyed locks on the exterior for security, but interior access must always be unobstructed for safety.
