Operation (continued)
3. General
• If the batteries are fitted and the power is removed to the IEGL at any time during its operation, the lock will revert to its pre-selected
state of either unlocked or locked. The IEGL has been designed to operate with high quality disposable alkaline batteries and may not work
correctly with alternatives. Should the batteries become flat the lock will sound an alarm to indicate a battery change is required
• If the batteries are not replaced once they have become depleted, the IEGL will automatically revert to the Fail Maintained state; i.e. in the
event of a power failure the lock will stay in the position it was in before the power was removed
• The three monitors can be used to provide door and bolt position information regardless of the locks configuration
• Manual operation of the IEGL is available by removing the cover to allow access to the lock mechanism. The supplied key can be used to
open and remove the cover and once access is available a screwdriver can be inserted into the centre of the large gear and turned to move
the bolt pin in or out.
Clockwise turning of the large
gear will retract the bolt pin.
4. Alarms
• To offer instant feedback about the locks state, the IEGL has an on board beeper which sounds at various times. The table below details the
different alarms expected from the IEGL
Locked confirm
Unlocked confirm
Failure to lock / unlock
Battery replacement
Diagnostic
• If the Failure to lock / unlock alarm has been sounded it is important that the cause of the obstruction is investigated immediately. As the
alarm sounds to indicate the bolt pin has not completed its correct action, it is possible that the gate is unsecured so the security of the
building is at risk. Any obstruction that is identified needs to be cleared so the lock is free to operate as normal
1 short beep
2 short beeps
5 long beeps
5 short beeps sounded 5 seconds after a lock activation and repeated every 10
minutes until the batteries are replaced
Various beeps – used for service
Anti-clockwise turning of the large
gear will extend the bolt pin.
