SECO-LARM Surface-Mount Electric Rim Strikes
2SECO-LARM U.S.A., Inc.
The SECO-LARM Surface-Mount Electric Rim Strikes are designed with the strength and durability for use
with rim-type exit devices with a Pullman latch bolt (3/4" throw for the SD-998C-D3Q, 1/2" throw for the
SD-998C-D3AQ). The strikes feature 12/24 VDC operating voltage, selectable fail-safe/fail-secure operation,
horizontal adjustment, and a surface-mount metal housing, eliminating the need for frame cutting during
installation.

Installation:
1. Set either fail-safe or fail-secure operation. See "Selecting
Fail-Safe/Fail-Secure," below.
2. Measure the center line of the latch, labeled "Y" (see Fig.1).
3. With the door closed, measure and mark the latch line on the door
frame, labeled "X" (see Fig. 2). This will correspond with the inside
of the strike keeper as shown in Figs. 3 and 4.
4. Remove the four cover screws, and remove the cover.
5. Using the strike as a template centered on the latch center line "Y,"
and so that the inside of the strike keeper is aligned with the door
latch line "X," mark and drill the two outer mounting holes and the
cable access hole.
6. Make the wire connections (see "Wiring Diagram" on pg. 4) and
then mount the strike to the frame with the Philips flat-head screws.
Check the location and ensure that the door latches properly and
adjust the strike horizontally as needed.
7. Tighten the two mounting screws and mark the locking hole
locations (the two inner holes, see Fig. 5).
8. Remove the strike and drill the two locking holes. Insert the blind
nuts into the locking holes. Reinstall the strike as before and lock
into place with the hex socket head cap screws into the blind nuts.
9. Replace the cover and reinstall the screws.

Electric strike does not activate
Dismount the strike and check that the wiring connector is connected properly.
Ensure the wiring connector is connected to a 12 or 24VDC 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 or push-button switch) 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.
Strike makes a buzzing sound Connect the strike to a DC power supply.
