3. Setup and Installation
3.1 Pre-Installation Checklist
- Verify door frame material and dimensions. A minimum 1-3/4 inch frame is required.
- Ensure appropriate power supply (12VDC or 24VDC) is available.
- Gather necessary tools: measuring tape, drill, appropriate drill bits, screwdriver set, wiring tools.
3.2 Mounting the Lock
- Carefully measure and mark the desired location for the lock body and strike plate on the door frame and door edge, respectively.
- Create the necessary cutout in the door frame for the lock body. The SpaceSaver design allows for a simple cutout.
- Secure the lock body into the cutout using the provided fasteners. Ensure it is flush with the frame surface for proper operation and aesthetics.
- Install the strike plate on the door edge, aligning it precisely with the bolt mechanism of the lock.
3.3 Wiring
The SDC 1091AIV supports both Failsafe and Failsecure configurations. Determine the required operation before wiring.
- Failsafe Operation: The lock will unlock when power is removed. This is typically used for egress doors where safety requires the door to open during a power failure. Connect the power supply according to the Failsafe wiring diagram provided with the product packaging.
- Failsecure Operation: The lock will remain locked when power is removed. This is typically used for security applications where the door must remain secured during a power failure. Connect the power supply according to the Failsecure wiring diagram provided with the product packaging.
- Ensure all electrical connections are secure and insulated to prevent short circuits.
3.4 Adjustments
The lock features an adjustable auto relock switch. Refer to the detailed instructions in the product packaging for specific adjustment procedures to fine-tune the relock timing.
4. Operating Instructions
The SDC 1091AIV Electric Bolt Lock operates in conjunction with an access control system or a simple switch, depending on the installation configuration.
- To Unlock (Failsafe): Apply power to the lock. The bolt will retract, allowing the door to open. Removing power will cause the bolt to extend, locking the door.
- To Unlock (Failsecure): Remove power from the lock. The bolt will retract, allowing the door to open. Applying power will cause the bolt to extend, locking the door.
- The adjustable auto relock switch will automatically extend the bolt after a set delay once the door is closed and aligned with the strike plate.
5. Maintenance
Regular maintenance ensures optimal performance and longevity of your SDC 1091AIV Electric Bolt Lock.
- Inspection: Periodically inspect the lock body, bolt, and strike plate for any signs of wear, damage, or misalignment. Ensure all fasteners are tight.
- Cleaning: Clean the exterior surfaces with a soft, dry cloth. Avoid using abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish.
- Lubrication: If the bolt mechanism appears stiff or noisy, a small amount of silicone-based lubricant can be applied to the moving parts. Do not over-lubricate.
- Wiring Check: Annually, inspect wiring connections for any signs of corrosion or loose terminals.
6. Troubleshooting
If you encounter issues with your SDC 1091AIV Electric Bolt Lock, refer to the following troubleshooting guide:
| Problem | Possible Cause | Solution |
