The SDC 1190AI is a fail-safe heavy-duty concealed mortise bolt lock designed for access control. Key operational requirements include a 24VDC power supply and the use of the included PR-1000 Power Regulator to manage heat and extend solenoid life. Proper installation requires precise mortising of the door or frame and alignment of the strike plate.
Installation Instructions
The lock can be installed in two configurations: Overhead Horizontal or Sidejamb Vertical.
Overhead Installation (Horizontal)
- Examine the top rail of the door to locate the strike plate. Mark the door and header.
- Attach the adhesive cutout template to the header, aligning it with your marks.
- Center punch tab-mounting screw locations and counter-sink for #10 screws.
- Saw or rout out the cutout area.
Sidejamb Installation (Vertical)
- Locate the center of the door height on the lock stile jamb.
- Mark the door stile and jamb for the strike plate.
- Attach the adhesive cutout template to the jamb, aligning the top of the cutout with your mark.
- Center punch and counter-sink for #10 screws, then saw or rout the cutout.
Finalizing Installation
- Attach mounting tabs inside the cutout.
- Connect power supply leads to the lock leads (refer to wiring diagrams).
- Insert the lock into the cutout. For horizontal installation, the bolt end must be nearest the lock stile. For vertical, the bolt must be at the top.
- Secure with #10-32 machine screws.
- Use the strike plate as a template to mark and drill screw holes, then attach the strike.
Auto Relock Switch (ARS) Adjustment
The ARS is factory-set for a 1/8" clearance between the top of the door and the transom bar or head jamb. If the gap is wider:
- Loosen the lock nut.
- Turn the switch assembly clockwise until the proper adjustment is reached.
- Tighten the lock nut securely.
Wiring and Power Regulator
The PR-1000 Power Regulator is included to reduce power consumption and heat. It is highly recommended for continuous duty applications.
- Input Voltage: 12/24 VDC/VAC (+/-10%). Note: 1190A operates at 24VDC only.
- Follow the specific wiring diagram provided in the manual for "Wiring with PR-1000" to ensure correct solenoid and switch connections.
Troubleshooting
- Bolt does not project: Check voltage and alignment of the strike.
- Bolt projects but chatters: Voltage is too low.
- Bolt will not retract: Strike is mis-aligned.
Practical help
Common problems
Bolt does not project
Check voltage and alignment of strike.
Bolt projects but chatters
Voltage is too low.
Bolt will not retract
Strike is mis-aligned.
Before use
- Verify 24VDC power supply.
- Ensure proper alignment of the strike plate.
- Check door gap clearance (1/8" recommended).
- Confirm PR-1000 regulator installation for heat reduction.
