Exterior Door Electrified Exit Device Application

Secure your building's primary access points with our Exterior Door Electrified Exit Device Applications. Engineered for durability and high-frequency use, these configurations pair weather-resistant electrified exit hardware with ruggedized exterior keypads or card readers. This setup allows for secure, credentialed entry from the outside while ensuring a code-compliant mechanical exit from within—making it the ideal solution for main entrances, employee side-doors, and gated courtyard access.

System Operation: 

This application provides high-security perimeter control by managing exterior access while maintaining a fail-secure state during power loss .

• Door normally closed and locked by electric latch retraction exit device.
• Door released on exterior side by remote switch (card reader, keypad)
• Door released on interior side by exit device.
• The electric latch retraction provides remote latchbolt retracting ability.

Operations Summary:

• Secured State: The door is physically locked from the exterior (or "unprotected") side. The latch is extended, and the exterior lever is rigid.
• Authorized Entry: A user presents a valid badge to the card reader or enters a code into the keypad.
• Hardware Release: The system sends power to the electrified exit device or exit trim. This "unlocks" the lever, allowing the user to turn it and retract the latch manually.
• Relatching: Once the door closes and the access control timer expires, the exterior lever returns to its locked state.
• Free Egress: Occupants exiting the room simply press the push bar. The latch retracts mechanically, providing an immediate exit regardless of the building's electrical status.
• Fail-Secure Security: In the event of a power outage, the exterior side remains locked (fail-secure), while the interior remains free for exit.
