Surface-Mount Electric Rim Strikes
SECO-LARM U.S.A., Inc. 3
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.
Selecting Fail-Safe/Fail-Secure
1. Remove both locking screws #1.
2. Loosen both sliding screws #2, slide to
the desired fail safe or fail secure setting
(factory default), and retighten.
3. Reinsert and tighten locking screws #1 to
lock the desired fail safe or fail secure
setting.
