RECOMMENDED PREINSTALLATION CHECK
FOR SURFACE MOUNT STRIKE

1. Determine that door is properly adjusted; D oo r mu st operate
properly in order for system to provide best results.

2. Door must swing properly, without interfering with jamb or sill

3. The door should be equipped with a door closer and the door
clo s er “lat c h m ode” mus t ho l d do o r in a c o mple tely clos ed
po sition in orde r to avoid t he lock latch from ap plyin g press ure
against the releasing latch portion of the electric strike.

4. E lectrical wire conne ctions must be compl ete d a nd rea dy to
be terminated inside the frame.

5. Confirm that the power line in the f rame is the correct voltage
and that the switch works properly.

5. C onfirm pr oper cleara nce exists between t he end of t he lock
latch and jamb.

7. The ele ctri c do or s trik e m u st b e a lign ed p rope rly with loc k

INSTALLATION PROCEDURE:

CAUTION: TO AVOID ELECTRICAL SHOCK AND
INJURIES, BEFORE DOING YOUR WIRING, TURN OFF
THE POWER FROM THE CIRCUIT BREAKER.

1. Mark the end position of the exit devices latchbolt on the
doorframe. (take off the original strike if present). See
Figure 1.

2. Using the marks you just made as your guide, position
over the mark on the frame. Make sure that the
Auxiliary latch rides up properly over the edge, and
is engaged, and that the door is in the fully closed position.
See Figure 2

3. When you are confident with the position,
mark two perpendicular edges on the frame.
See Figure 3

4. Put aside the strike for a moment and place the spacer
supplied inside the marks you just made on the frame

5. Using the spacer as a template; mark the two mounting
holes and the wire exit hole. If you are using the optional
anchor pins, mark the anchor pin positions using the
spacer as a template. See Figure 4

Figure 1

With the door closed,
mark the p0sition of
the bolt on the frame.

Figure 2

Position on
the frame and mark
position.

6. Using a #7 bit, drill the two mounting holes and tap them
1/4-20.

7. Using a 3/4 inch diameter bit, drill the power wire exit
hole.

8. If you are utilizing the anchor pin system, use a #30 bit,
drill the four anchor pin holes.

9. Deburr any sharp edges around the holes after drilling,
so wires will not be accidentally cut or damaged while
installing.

10. Pull the power wiring down the door frame and through
the 3/4 inch diameter power wire hole.

11. Using the provided sealed crimp connectors, terminate
the quick connect socket assembly to the power wires.
See Figure 5 (NOTE: not polarized)

12. If you intend to use the anchor pins system, insert
them into the four holes on the back side. See
Figure 6. If you also intend to use the 1/8” thick spacer
plate, you can now slip the plate over the pins.

13. Snap together the power supply side connector coming
off the frame. Carefully push the
wires and connectors back into the frame.

14. Using the 2 mounting screws, mount the strike to
the frame.

15. Adjust the strike to the desired position and tighten the
mounting screws using the 3/16 inch Allen wrench.

Figure 4

Use the spacer as,
template to mark the
holes you desire to use.

16. Using the 3/32 inch Allen wrench turn the two
setscrews on the side until they support the
strike. DO NOT over tighten the setscrews.

17. Turn the power ON and test your installation.

18. Installation is now complete.

INSTRUCTIONS FOR CHANGING
FAIL SECURE TO FAIL SAFE
AND VICE VERSA:

To change the Fail Secure into a Fail Safe, open the mechanism
side (as shown on the right) by removing the mechanism cover
screws (3 places) and the cover. Lift the solenoid and gently pull off the
solenoid plunger. Replace the BLUE colored spring with the RED colored
spring. Pull off the actuator cam, and flip it to use the cam profile for Fail
Safe (the side without an “X” mark). Before closing the unit, make sure that
the wires are properly seated on the wire channel (see figure on right).
Save the BLUE colored spring for future use.

For changing from Fail Safe to Fail Secure, just reverse the above
procedure.

Use t he BLUE colo red
solenoid spri ng.

Turn the actuato r cam over
t o utilize th e Fai l Safe
si de of the ca m pro file.

Use t he RED color ed
solenoid s pring .

DO NOT OPEN

THIS SIDE.

Seat w ires properl y in
the housing channel so
the cover will seat flat.

Fail Secure

You should have
th e “X” mark
on top of the
ac tuator cam.

Configuration

(Standard)

TROUBLESHOOTING THE COMPLETED INSTALLATION

SYMPTOM: Electric release is not actuating:

1. Verify proper voltage is present AT STRIKE. If voltage
is present: the strike may have been affected during
the installation, or dirt or debris may be preventing
proper operation. Inspect electric release and clean.
DO NOT LUBRICATE SOLENOID.

2. If voltage IS NOT present:
Verify Circuit breaker is on
Verify voltage at the transformer/power supply output.
Verify that there are no additional, external switches or
devices which may be interrupting your circuit.
Check for damaged wiring or bad wire splices.

SYMPTOM: Door will not open but strike is working

• Check for other locks on door

Fail Safe

You should NOT
s ee the “X”
on top of the
ac tuator cam.

• Check for proper lock-latch engagement

• Check for excessive back pressure on door release

latch by following these steps:
Push the door from the outside to try and relieve
the bolt to latch pressure and actuate the strike.
While unlatched swing the door open. If the door
opens, then the bolt may be applying
pressure to the latch. Adjust the position
to relieve the pressure.

Possible remedies include:

• Re-adjust (or install) a door closer

• Remove door silencers

• Correct excessive door warpage

• Re-center electric release in jamb

• Remove or trim weather stripping around the door
