The La Gard 39E is an electronic combination lock designed for security applications. Documentation details procedures for operation, combination changes, user management, and setup options including time delay and dual control modes. The lock utilizes a combination entry system and provides signaling to indicate valid or invalid entries, as well as user status. External signal integration is possible with the use of a La Gard Alarm Box, offering features like remote override and disabling lock operation.
Opening the Lock
The La Gard 39E lock is opened by entering a valid Manager or User combination. Upon successful entry, the unit will signal twice. Within four seconds of the double signal, the lock can be opened by rotating the keypad clockwise or turning the handle. An invalid combination entry results in three signals from the unit.
Manager Combination Procedures
Several operations require the Manager combination. To initiate these procedures, the Manager combination must be entered and the last digit held down until the unit double signals twice and the LED remains illuminated. This indicates the lock is in programming mode.
Changing the Combination
The Manager combination is required to change any combination – Manager or User. The process involves the following steps:
- Enter the existing combination and hold down the last digit until the unit double signals and the LED stays on.
- Press the “0” key.
- Press the User number (1 to 9) for which the combination needs to be changed. The unit will signal twice.
- Enter the new combination, then re-enter the new combination to confirm.
- If an error is made during the process, wait thirty seconds and repeat steps 1 through 4. A double signal confirms a valid combination entry, while a triple signal indicates the operation was unsuccessful.
Deleting a User
The Manager combination is also used to delete a user and their associated combination. The steps are as follows:
- Enter the Manager combination and hold down the last digit until the unit double signals twice and the LED stays on.
- Press the “3” key. The unit will signal twice.
- Press the User number (1 to 9) to be deleted. The unit will signal once.
- Deletion removes the user and their combination, but the user feature remains active and can be re-enabled.
- If a mistake is made, wait thirty seconds and repeat steps 1 through 3.
Checking User Status
The status of a user – active, disabled, available, or unavailable – can be checked using the Manager combination. The procedure is:
- Enter the Manager combination and hold down the last digit until the unit double signals twice and the LED stays on.
- Press and hold down the “7” key. The unit signals twice.
- Press the User number (1 to 9).
- The unit will signal to indicate the user’s status:
- One signal: User is active.
- Two signals: User is disabled.
- Three signals: User is available.
- One extended signal: User is unavailable.
- Press “0” to exit the user status check.
Setup Instructions and Features
The La Gard 39E offers several configurable setup options. These options require the use of setup software and may necessitate a lock code level of 39E v1.09 or higher.
Combination Length
The lock allows for a combination length of six to nine digits.
Time Delay
A time delay function can be enabled, allowing for a delay period of 1 to 99 minutes and an open period of 1 to 19 minutes. If the Time Delay On feature is not selected, the time delay function is inactive but can be enabled later using Manager instructions.
Dual Mode
When enabled, Dual Mode requires two combinations to operate the lock. Both the Manager and one additional active User must have valid combinations for the lock to open.
External Signals
The lock can be integrated with a La Gard Alarm Box (P/N 2789NC) to utilize external signals. These signals can be programmed to:
- Disable lock opening with a valid combination.
- Override the time delay function.
- Enable remote override functionality.
Note that only one type of external signal can be selected. The remote override function is only available if enabled using setup software and with lock code level 39E v1.09 or higher.
Important Considerations
The documentation emphasizes performing user management and combination changes with the door open. If a mistake is made during any procedure, a thirty-second wait is required before repeating the steps. The lock supports an external input signal via the Alarm Box, which can be configured to disable the lock, override the time delay, or enable remote override functionality. The availability of certain features, such as remote override, depends on the lock’s software version and configuration through setup software.
Conclusion
The La Gard 39E electronic combination lock provides a robust security solution with configurable features. Proper operation requires understanding the procedures for entering combinations, managing users, and utilizing the setup options. The integration with the La Gard Alarm Box expands functionality through external signal control. Adhering to the documented procedures, particularly performing operations with the door open and allowing for recovery time after errors, is crucial for maintaining the lock’s functionality and security.
