All models are designed with intelligent logic circuit allowing the bolt to
keep retracting until the door is properly closed.
A. When the swing-through door is closed, the relock delay time begins
and the reed switch in the lock detects the sensor magnet in the strike
plate.
B. The bolt projects after relock delay time expires and keeps projecting
until the door is closed in the correct position and locked.
C. After the bolt is projected to lock the door, the current draw will drop
to the normal state.
D. The reed switch will automatically switches off at the same time when
the door is locked.

Mortise Mount Installation (For Hollow Metal Doors)
Please refer to the particular template for each specific
cutting size and location to drill the screw holes.
Installation Instructions
Ensure that the door frame can accommodate the lock body.
Also check if it is possible to place the wires inside the door
frame.
Ensure that the double action door swings back to the correct
position so the dropbolt can lock up immediately.
Check if the regulated power supply or controller provides the
correct current draw (Pull-in current: 0.9A/12VDC, holding
current: 0.3A/12VDC).
DO NOT OIL OR LUBRICATE
This product must be used in conjunction with a quality
floor spring or door closer to ensure positive realignment
on closing.
Warning:
The connection of an incorrect voltage may result in damage and
is not covered by the product warranty. Select the appropriate
power supply cable to ensure if the lock receives sufficient power
to operate. This product has been designed for use in weather
protected areas and normal circumstances, hence it does not
require any maintenance.

Installation Instructions
1. Make sure the installation location and clean the surface of
glass.
2. Take off the sticker on the back of the spacer and attach to
glass. Each VGL bracket is 14mm width and spacer is
1mm thickness. Add more spacers if needed according to
glass thickness. Use silicon to secure the VGL bracket firmly.
3. Tighten the set screws with the Allen wrench, secure the
dropbolt to the glass bracket, and then install the cover.
Caution:
1. It is suggested to attach the spacer to the inside of the door.
2. Tighten the set screws lightly to prevent breaking the glass.

Trouble Shooting
Problem Possible Cause Solution
Dropbolt is not activated
when the door is closed
Bolt keeps projecting
Bolt cannot retract
The gap between the strike plate
and the dropbolt is large
Low voltage /current
Low voltage/current
Dropbolt is not locked properly
Strike plate is misaligned
Change the sensing range to less than 5mm.
Check the output voltage and the current draw.
(Pull-in current: 0.9A/12VDC)
Check the output voltage and the current draw.
(Pull-in current: 0.9A/12VDC)
Adjust the door closer or the door hinge so that the
door is closed in the correct position.
Use on single action doors If the door hinge
cannot be adjusted.
Move or sway the door to release the bolt to open the door.
Use on single action doors If the door hinge cannot be adjusted.
