SDC FS23MIV – Frequently Asked Questions

1) What makes the SDC FS23M series a dual failsafe electric bolt lock?
The FS23M features dual failsafe operation where both the lock and monitoring circuits fail to the secure unlocked position during power loss. The right-angle design provides space-saving installation in narrow door frames.
2) What door types and frame configurations work with this lock?
Compatible with hollow metal, wood, and aluminum doors in commercial frames. The right-angle bolt configuration works best in applications where frame depth is limited. Verify door weight capacity and frame reinforcement requirements.
3) How do I determine left-hand versus right-hand installation?
Stand on the secure side facing the door. If hinges are on your right, it's right-hand. If hinges are on your left, it's left-hand. This model is configured for right-angle mounting specifically.
4) What finishes are available for the FS23M series?
Standard finishes typically include satin chrome, dark bronze, and black. Finish availability may vary by model. Check specific model specifications for exact finish options and order accordingly.
5) What voltage and current requirements does this lock have?
Most FS23M series locks operate on 12VDC or 24VDC with current draw specifications varying by model. Consult the technical specifications sheet for exact power requirements and ensure adequate power supply capacity.
6) Does this lock meet fire and life safety code requirements?
SDC FS23M series locks are designed for egress applications and typically meet UL listing requirements. Verify specific model certifications and ensure installation complies with local fire codes and AHJ requirements.
7) What accessories and parts are available for the FS23M?
Common accessories include door position switches, request-to-exit devices, and mounting brackets. Check our access control section for compatible SDC accessories and replacement parts.
8) What are the basic installation requirements?
Installation requires precise mortising into door and frame. Use manufacturer's template for exact measurements. Ensure adequate wire gauge for power runs and proper grounding. Professional installation recommended for proper alignment and code compliance.
9) How do I adjust the bolt throw and timing?
Most adjustments are made through internal mechanisms accessed after removing the lock from the door. Follow manufacturer procedures for bolt throw adjustment and timing calibration. Avoid field modifications that could affect UL listing.
10) What other SDC electric bolt locks should I consider?
Consider the standard FS series for different mounting configurations or the SecureLock series for higher security applications. Browse our SDC collection for alternative models based on your specific door and frame requirements.
11) What field conditions affect lock performance?
Temperature extremes, humidity, and door sag can affect operation. Ensure proper door alignment and weathersealing. Consider environmental ratings when installing in exterior or harsh indoor environments.
12) What are the critical measurements I need before ordering?
Measure door thickness, frame depth, and backset requirements. Note handing and any existing mortise preparations. Verify clearances for bolt travel and access to mounting points. Use manufacturer templates for precise layout.
