6.1 NO Mode (Fail-Security) Operation
This electric drop bolt lock operates in NO Mode (Fail-Security). This means:
- When there is no power, or in case of a power failure, the lock remains in a locked state.
- The lock will only unlock when power is supplied to the lock and an authorized signal is received from the access control system (e.g., pressing a push button, using a remote controller, or entering a code on a keypad).
6.2 Time Delay Function
The lock features an adjustable time delay function, which controls how long the door remains unlocked after an authorized signal is received. The delay can be set to 0 seconds, 3 seconds, or 6 seconds.
To adjust the time delay, locate the small switch or jumper on the side of the lock unit (refer to Image 6.1). Move the switch or adjust the jumpers to select the desired delay setting (0s, 3s, or 6s).
