Important - For vertical mounting of SD-997B series only, wires must come out
the top of the unit.
For single door
Mounting Location
Can be mounted opposite the door hinges, or on the header or
on top of the door away from the hinges. Mounting on the bottom
of the door is not recommended because of the possibility of dirt
and dust buildup. (see fig. 1)

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 (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-GBQ 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)
{
*
6) Blue – Door monitor, N.O. (active when door open)
IMPORTANT – Correct polarity of the red and brown wires is
critical. Incorrect polarity will burn out the solenoid !
*
Connect to an alarm control panel or warning device to show if
the door is open or closed.

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-GBQ & 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
SECO-LARM U.S.A., Inc.
3-Pin
Electric Deadbolt Installation Manual
door is closed but the deadbolt remains unlock. 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.
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-GBQ only (see figs. 5 and 6)
Because the SD-997A-GBQ 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-GBQ 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-GBQ 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.
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.
