Troubleshooting:

Problem:

Deadbolt does not activate
when the door closes.

Deadbolt activates when
the door is closed, but
does not lock the door.

How to reset unit.

For any other problems

Possible cause:

The sensor in the lock body
is too far from the magnet
in the strike plate.

Deadbolt may not be
properly going into the
deadbolt hole in the door.

Solutions:

• Try adjusting the strike plate, lock body position, or shims.

• Make sure the deadbolt is going into the hole and not hitting the
strike plate. If not, you must reposition the strike plate.

• If the deadbolt is going into the hole, it may be hitting the bottom of
the hole (if it is in a wooden door). In this case, drill a deeper hole.

• When testing, if necessary, reset the unit by grounding the orange
wire momentarily.

• Replace the unit, and test again. A problem unit can also be substituted
for a working unit in another door frame to see if it works there.

Optional Mounting Brackets Available for SD-997B Series :

Mount the deadbolt
and strike plate on
the door jamb instead

Installation

1. Determine where the deadbolt will be mounted (see fig. 1).

2. Tape the templates to the door frame and door (see fig. 3)
A. Align the templates so that the deadbolt of the lock body template

is centered on the deadbolt hole of the strike plate template.

B. Make sure to leave enough room at the ends of the lock body

and strike plate templates for mounting the mounting tabs.

3. Door frame cut (see fig. 4)
A. Cut out the space for the lock body.
B. Test the fit. The lock body should fit snugly inside the space.
C. Drill two 5mm screw holes as shown on the

4. Door cut and mount. (see fig. 4)
A. For wood doors:

1) Use a chisel to knock out a 3mm (
shown on the template.

2) Drill the magnet hole, 12mm (

3) Use four wood screws to mount the strike plate in the
chiseled space. The magnet should fit in the magnet hole.

4) Use a drill to drill out the deadbolt hole to a depth of 16mm (

B. For hollow metal doors:

1) Cut out the space for the strike plate.

2) Drill two screw holes for each of the two mounting tabs.

3) Use screws to fix the mounting tabs inside the hollow metal door.

4) Use screws to fix the strike plate to the mounting tabs.

5. Door jamb cut and mount (see fig. 4)
A. Cut out the space for the face of the lock body.

B. Drill one 5mm hole for each of the two mounting tabs.
C. Use screws to fix the mounting tabs inside the door jamb.

IMPORTANT – Push all the wires into the door frame. If
space is a problem, cut away part of the dust catcher inside
the frame, or carefully chip away part of the drywall, being
careful not to damage the wall.

F. Set the door lock delay timer (see fig. 8). This is the

time it takes the deadbolt to automatically lock after
the door is closed.

NOTE: For SD-997A-DQ & SD-997B-GBQ only – The

deadbolt automatically relocks 4 seconds after an
optional external push button (egress button) is
pressed, if the door was not opened.

The lock body has a sensor mechanism
wherein it can detect if the strike plate is in
close proximity (such as when the door is
closed). If the door was closed but somehow
the strike plate was not aligned properly, the
door monitor indicator may indicate that the

During this time the lock body may attempt multiple
times to relock the door and if it fails, it will stop to
prevent the solenoid from burning out.

However if the lock body and the strike plate are too far
apart, the lock body will not attempt to lock the door and the
deadbolt will not throw out.
