About Remote Disable
Systems using 702, 703, 704, and 705 Keypad models support a configurable Input Signal. Using this Input Signal requires installing a Battery/Alarm Box (Item/Order #704045).
Note: Although 701 locks do not support configuration, they include an input signal that controls the Remote Disable (Lockout) function.
Remote Disable Behavior in Multi-Lock Systems
In a multi-lock system, Lock #1 monitors the Input Signal. When the signal is asserted, Lock #1 performs one of the following actions based on its configuration:
- Ignored: The Input Signal has no effect on system operation.
- Remote Disabled / Lockout (Default): The system blocks all open requests for all locks, regardless of which lock the user attempts to open.
- Time Delay Override: The system cancels Time Delay for all locks. Any lock can open immediately if the user has open privileges and enters valid credentials. If a lock is in the Delay Period or Confirmation Window, the system cancels the delay and allows immediate access.
- Dual User Override: The system ignores Dual User requirements, allowing a single user to open a lock or access menus.
Remote Disable Using the Alarm Box
When installed with the Alarm Box, the system can disable the lock opening sequence by asserting a signal at the Alarm Box. An external alarm or control system typically provides this signal to prevent the lock from opening.
Operational Notes and Limitations
Observe the following conditions when using the Remote Disable feature:
- Remote Disable does not prevent users from accessing menus on a display keypad.
- The system must receive the asserted signal before user authentication to recognize the Remote Disable condition.
- Duress combinations continue to trigger the alarm signal, even when Remote Disable is asserted.
- On display keypads, the system shows the message “Lock #x NOT open” when Remote Disable is asserted. The value x represents the lock targeted for opening.
Note: LA GARD software and the Alarm Box are not UL evaluated.
