Product Overview
The GL1 Electromechanical Gate Lock is designed to secure a wide
variety of vehicle and pedestrian gate applications where security and
weather resistance are required. The GL1 functions equally well in both
electrically and manually operated gate installations and can be used for
swing gates, sliding gates, stock cage gates or other applications.
Product Features:
• 2000 lbs holding force
• Operates under preload up to 100 lbs.
• Automatic dual voltage—no field adjustment required
• Manual key override (right or left hand)—Fail Locked only

• Self-aligning receiver (up to +/- 1/2" horizontally or vertically)
helps compensate for gate misalignment and sag
• Tamper proof cast housing
• Latch status monitor switch (SPDT)
• ½”-14 NPSM inside pipe thread
• Surface Mount
• Black finish

Installing the GL1 Electromechanical
Gate Lock
Installation Concerns
CAUTION: It is vital that all welding be completed prior to
making any electrical connections to the mounted
GL1. Welding in or around an electrically-connected
lock assembly can cause damage to the electronic
components.
• Installation should be performed by a qualified service person, who
conforms to all local codes and complies with The National Electrical
Code (or equivalent).
• The FMK-SL (Sliding Gate) and the FMK-SW (Swing Gate) mounting
bracket kits are recommended for installing the GL1.
• The GL1 must be mounted in the upright vertical position with the
conduit opening on the bottom.
• The GL1 should not be used for dual swing gates.
Perform a Pre-Installation Survey
Due to the variety of mounting configurations available with this product,
it is strongly recommended that an initial physical survey and
assessment be made of the actual area where the lock will be installed to
determine the optimal method of mounting prior to installation. The
following should be considered:
• Physical strength of mounting areas
structural integrity of mounting surfaces be strong enough to meet or
exceed the holding force of the lock.
• Protection of the lock from external attack
must be protected to a reasonable degree from potential damage
due to intruders or vandals.
• Convenience and accessibility of area to be protected
: It is recommended that the

assembly should be installed in a location that will not hinder or
create a potential safety hazard to authorized personnel routinely
accessing the protected area.
Because of the diversity in gate construction and installation
configurations, optimum mounting platforms may be achieved by welding
adequate size metal plates, channels or tubing to the fence frame and
the gate. Formed angle and brackets along with appropriately sized
fasteners may also be utilized to mechanically secure mounting
platforms for the lock and strike.
Figure 1, “Swinging Gate Mount,” Figure 2, “Sliding Gate Mount,” Figure
3, “Installation Spacing Dimensions,” and Figure 4, “Chassis Welding,”
show some basic mounting configurations on a chain-link style fence
frame and gate.

Perform the Cylinder Lock/Cover Hole Plug
Installation
NOTE 1: The GL1 provides for the additional function of an optional key-
operated cylinder lock. The cylinder lock can be installed to
either side of the lock cover, because the GL-1 lock latching
mechanism features an actuator lever that will engage the
cylinder lock from either side.
NOTE 2: IF the cylinder lock is not
(provided) must be installed on both sides of the cover.
1. SELECT the side of the lock cover that will be the most convenient
for the key access after installation if installing the optional manual
override.
2. INSTALL the optional cylinder lock.
NOTE: The following step is critical to the proper operation of the
mechanical override. The cam of the cylinder (“MS” type)
must come into contact with the actuator lever pin to
operate the release trigger of the lock mechanism when
the cover is assembled to the lock chassis.
a. ASSEMBLE the cam, as necessary, so that the key rotation
moves the cam to point toward the rear (opening) of the cover.
b. INSERT the cylinder lock with applicable spacer (i.e., Sargent
Number 90) into the applicable cover hole (see table below and
Figure 5, “Cylinder Lock Installation”).

c. SLIP the spacer over the cylinder lock and INSERT the cylinder
lock into the applicable side hole on the lock cover.
d. SLIP the lock mounting nut over the cylinder lock inside the
cover and THREAD the nut onto the lock body by hand.
e. TIGHTEN to secure the nut in place using the provided cylinder
nut tool.
f. INSTALL a cover hole plug in the opposite side of the cover, and
SECURE its retaining nut using the provided retaining nut tool.
NOTE: The following steps are performed if the cylinder lock is not
used.
3. INSTALL the two cover hole plugs (provided) through both sides of
the cover (see Figure 6, Cover Hole Plug and Retaining Nut”).
4. SECURE the cover hole plugs in place using the retaining nuts and
provided cylinder nut tool (see Figure 6, “Cover Hole Plug and
Retaining Nut”).

NOTE: The FMK-SL (Sliding Gate) and the FMK-SW (Swing Gate)
mounting bracket kits are recommended for installing the GL1.
1. IF not using one of the recommended mounting bracket kits,
THEN USE the included template to locate and install mounting
hardware.
2. INSTALL the lock chassis using the top two lock chassis mounting
positions.

versus distance:

3. ROUTE all electrical wiring through either the provided wire conduit
coupling in the bottom of the lock chassis or through the ½” [12.7
mm] hole in the rear of the lock mounting chassis (see Figure 7,
“Wire Routing”).
4. FEED wires through the hole in the side of the lock chassis opposite
to the cylinder lock, if installed.
5. IF there is no cylinder lock installed,
THEN FEED wires through either side of the lock chassis (see
Figure 7).

6. CONNECT wires to the terminal block on the PC board (see
Figure 8, “PC Board Terminal Block,” and Figure 9, “System
Connections”).

CAUTION: Lock cover must be installed straight on to avoid
possible damage to the PC Board.
1. INSTALL the lock cover over the lock mounting chassis by placing
the cover straight on and then sliding to engage.
2. SECURE the cover to the mounting surface using two (2) socket
head cap screws and two (2) split lock washers.
3. PLUG conduit fitting if not used, welding the plug for maximum
security.
