Fail Locked Mode:
In this mode, at loss of power, the lock’s latching mechanism will lock when the gate is closed
and remain in the latched/locked condition until power is restored or the mechanism is
disengaged by the manual override.
Fail Safe Mode:
In the fail safe configuration, when there is a loss of power to the lock, the latching mechanism
will not lock when the gate is closed and will unlock if the gate was previously secured.
Each unit can be converted from the fail locked to the fail safe mode (or fail safe to fail locked)
as required. If this is necessary, follow the step-by-step instructions provided in Section 6 GL1
Fail Locked to Fail Safe Trigger Conversion.
Note: The manual override is non-functional in the fail safe mode.
Electrical and Cover
Using the following instructions complete the installation of the lock mounting chassis to the
fence frame.
1. Verify that all necessary welding has been completed.
2. Route all electrical wiring through either the wire conduit coupling provided in the bottom of
the chassis or through the optional 1/2” (12.7mm) hole in the rear of the lock mounting
chassis. Note: If the conduit coupling is not used, a 1/2”-14 NPS conduit or pipe plug should
be installed and tack-welded into place to close the fitting.
3. Feed wires through the obround hole in the right side of the lock mounting chassis.
Wire Routing
4. Make all necessary wire connections at the terminal block on the PC Board. See Section 6,
page 9 for electrical wiring diagram.
Note: Ensure wiring does not interfere with the manual override cam lock if it is installed to the
right side of the lock.
5. After the electrical wiring has been completed, install the lock cover over the lock mounting
chassis by engaging the lip at the top/rear of the cover with the top edge of the mounting
chassis. Secure the cover to the mounting surface using two (2) socket head cap screws,
two (2) split lock washers and two (2) flat washers. Fully tighten the screws using a hex
wrench.
