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 SD-977A-DQ/SD-997BQ 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 (1/8-inch) deep space as
shown on the template.

2) Drill the magnet hole, 12mm (1/2”) wide by 6mm (1/4”) deep.

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 (5/8”).

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.
D.

SD-997A-DQ only: Insert the lock/unlock cylinder (see fig. 5).

E. Connect the wires, and insulate them (see fig. 7):

1) Red – Power input (+)

2) Brown – Power input (-)

3) Orange – Control wire (ground to release bolt)

4) Green – Door monitor, COM

5) Yellow – Door monitor, N.C. (active when door closed)

wires is critical. If you reverse polarity, the solenoid
will burn out!

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: 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 door is

closed but the deadbolt remains unlock. During this time the
lock body may attempt multiple times to lock 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.

IMPORTANT – The lock body and strike plate must be
properly aligned and next to each other in order for the
product to function properly.

G.

Pull the vinyl covering off the faceplate, and place the faceplate
over the face of the lock body. Use screws to fix the faceplate
and lock body to the mounting tabs.

6. For SD-997A-DQ only (see figs. 5 and 6)
Because the SD-997A-DQ offers fail-secure operation, the door
locks if power to the unit is cut. For such a situation, a separate
manual lock/unlock cylinder is provided for manual operation.
A. Insert the cylinder as shown in Fig. 5, and secure it to the

lock body with the provided long screw. Turning the key or
the manual knob will unlock the SD-997A-DQ manually.

B. Two separate templates are included for drilling holes in the

door frame for the key and manual knob.

C. A separate 3-pin connector for the SD-997A-DQ can be

connected to an alarm panel or annunciator to alert when
the door is locked or unlocked.

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.

Installation notes:

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.
