How Does the Emergency Door Release Work?
The EBELCO E-108E-G uses a microswitch to change the electrical circuit state when the break-glass element is activated.
Normal Condition
The unit remains in its configured standby contact state.
Emergency Activation
The glass element is pressed firmly or broken, changing the microswitch contacts.
Access Control Response
The connected release circuit changes state, allowing a compatible access control system to release the door lock when correctly wired.
Reset
After testing or activation, the glass element can be replaced if necessary and the mechanism reset using the designated key.
The exact unlocking response depends on the selected NO/NC contacts and the connected lock and control circuit.
Applications
Access Control Systems
Used as an emergency release input in compatible electronic door access control installations.
Electromagnetic Door Locks
Can be connected to a compatible electromagnetic lock release circuit, subject to the approved wiring design.
Commercial Buildings
Suitable for access-controlled doors in offices, commercial facilities and other indoor environments.
Hospitals and Institutional Buildings
Can be considered for appropriate emergency door release arrangements where required by the project design.
Security-Controlled Doors
Suitable for compatible controlled-access doors where a manual emergency release interface is required.
Why Choose EBELCO E-108E-G?
Emergency Manual Release
Provides a clearly defined manual activation point for emergency door release circuits.
Flexible Wiring
The SPDT microswitch provides COM, NO and NC contacts for compatible circuit configurations.
Test Key
Allows the microswitch mechanism to be tested and the unit reset without unnecessarily replacing the glass during routine testing.
Compact Surface Mounting
Its 89 × 89 mm front dimensions allow installation in a compact wall-mounted arrangement.
Access Control Integration
Can be incorporated into a compatible door security system alongside electromagnetic locks, access control panels and other release devices.

The actual wiring must follow the manufacturer’s diagram and the approved system design. The release device must not be assumed to provide direct power to a lock; it typically changes the state of a control circuit.
Important Installation Notes
- Install in an appropriate indoor location.
- Follow the manufacturer’s wiring diagram.
- Verify the operating voltage and current rating of the connected circuit.
- Select NO or NC contacts according to the approved access control design.
- Test emergency release operation after installation and during scheduled maintenance.
- Ensure the complete door release arrangement complies with applicable fire and life-safety requirements.
An emergency door release unit is one component of the overall safety arrangement. Its presence alone does not establish that a door or building complies with all applicable emergency-egress requirements.
