INSTALLATION INSTRUCTIONS
55 SERIES ELECTRIC STRIKE
55-ABC Universal Strike Pak for
multiple cylindrical and mortise
lockset applications.
55-A for cylindrical locksets
With 1/2" to 3/4" latch.
SDC 55 Series heavy duty electric strikes are designed
for use with cylindrical and mortise locksets and mortise
exit devices. Several faceplate configurations eliminate
the need for centerline relocation, making them perfect
for new or retrofit construction.
FEATURES:
Non-handed
No Centerline relocation
Up to 3/4” latch and 1” deadbolt
1/8”Horizontal alignment adjustment
Field selectable Fail-Safe/Fail-Secure
Field selectable 12/24VDC
Stainless steel, corrosion resistant
Tamper resistant heavy duty construction
Plug-in connector
Fits ANSI 115.1 frame prep. with face modification
Patent pending
OPTIONAL MONITORING OUTPUTS:
LCM (Keeper Deadlocked Monitor)
Signals keeper is closed and deadlocked and/or unlocked.
LBM (Latch Bolt Monitor)
Signals latch is extended into strike and/or retracted.
DBM (Deadbolt Monitor)
Signals deadbolt is extended into strike and /or retracted.
55-B / 55-C For mortise
locksets with up to a 3/4" latch
55-D / 55-E / 55-F for mortise
locksets with latch and deadbolt
INSTALLATION
1. Verify lock compatibility, refer to page 2 and Fig. 6, page 4.
2. For proper frame preparation, refer to template drawings,
Fig. 4 & 5, page 4.
2. Factory supplied in Failsecure mode. For Failsafe mode refer
to Fig. 2, page 3
3. Determine minimum wire gauge required. See wire gauge chart below.
4. CAUTION! Before connecting power wires check for proper operating
voltage at opening with a volt meter. Voltage must be within +/- 10%
of strike operating voltage for proper operation.
5. Configure strike for 12 or 24VDC operation. Refer to pigtail power
connector wiring in Fig. 1, Page 3. Connect wires to power source.
6. To install the strike into the frame opening:
A) Position the wiring either down or up or toward the back of the
hollow metal frame. Make sure wires are completely clear of strike,
so they are not pinched when mounting strike in the frame.
B) Insert mounting screws through the faceplate and secure into
mounting tabs.
7. After installation check horizontal alignment. There should be 1/32”
allowable movement when the door is pulled toward the keeper.
8. ALIGNMENT ADJUSTMENT: Loosen mounting screws, shift strike
body behind faceplate horizontally as shown in Fig. 3A, page 3,
then tighten mounting screws.
9. For excessive horizontal alignment issues, remove shim filer bar from
the keeper as shown in Fig. 3B, page 3
10. The Electric Door Strike MUST be installed in such a way and in such a
location so as not to impair the operation of an emergency exit or panic
hardware mounted on the door.
