SECO-LARM Mini Electric Door Strike
SECO-LARM U.S.A., Inc. 3
Features:
Installation:
For Timely®interior door frames (see Fig. 1):
The no-cut door strike should fit into the door strike cutout of
Timely interior door frames without making any new cuts or
screw holes. However, in rare cases because of how the door
latch was installed, it may be necessary to cut out a small piece
of the frame, or drill new screw holes.
For non-Timely®interior door frames:
1. Measure the center line (see Fig. 2):
a. Measure the distance from the floor to the center
of the door latch. Ignore the location of the
deadlatch pin when taking measurements.
2. Measure the latch line (see Fig. 3):
a. Measure the distance from the door latch to the
edge of the door jamb. This is the “door latch line”.
3. Align the included mounting template to the latch line
and center line (see Fig. 4).
4. Using the template as a guide, cut a hole in the frame
to fit the door strike. In most cases, the surface-mount
no-cut strike plate will work.
5. In the rare case where a deeper cut into the frame is
needed to match the door latch, use the template to
cut out space for the low-cut strike plate.
6. Mount the electric door strike with the appropriate
strike plate into the hole to ensure it does not interfere
with the closing of the door, and that it properly
catches the door latch. Make adjustments if needed.
Wire the electric door strike (see Fig. 5):
1. Connect the two wires of the electric door strike to
the wires from the access control or egress device
(keypad, pushbutton switch, pushbar, etc.), and
insulate with electrical connectors or electrical
tape. Polarity is not important. Make sure no bare
wires are exposed.
2. Conceal all wires in the door frame.
3. Tightly mount the electric door strike to the frame
with the included door frame mounting screws.

Electric strike does not activate
Unmount the strike and check that the two wires are
connected properly
Ensure the wires are connected to a 12VDC source
Use a multimeter to test that the strike is receiving the
proper voltage and amperage. If it is not, it may be
necessary to use heavier gauge wires, or increase the
output of the power supply
Make sure the activation device (keypad, pushbutton
switch, etc.) is working properly
Door does not open when the electric strike
is activated
Check that the door latch is operating properly and
replace if necessary
The position of the electric strike may need to be adjusted
by moving it or adding washers or shims
