Bouton de libération de porte d'urgence réglable
A protected green manual release unit that interrupts or signals the access-control circuit when emergency door unlocking is required.
- Resettable Operation
- Protective Clear Cover
- Dual Status Indicators
- Emergency Release Contacts
Introduction de produit
The resettable emergency door release button provides a deliberate manual action independent of normal credential control. Lifting the clear protective cover and pressing the center panel changes the internal contact state so the access system can release its fail-safe lock or register an emergency command. A reset key returns the mechanism after the event, eliminating the glass fragments and consumable insert associated with traditional break-glass units.
Key Features
A clear hinged cover helps prevent accidental activation during routine corridor activity.
The resettable mechanism can be restored with a service key after inspection.
Separate contact sets and red/green indicators support local and controller status feedback.
