Fail-Secure Electric Strike Plate with Reversible Faceplate, 1,000-lb Jaw Strength, 500,000-Cycle Endurance, 8-16VAC/12VDC Operation, and Corrosion-Resistant Construction for Wood Door Access Control Installations
The Seco-Larm SD-994A-A1SQ is a fail-secure electric strike plate with a reversible symmetric faceplate for left- or right-hand wood door installations using cylindrical locksets. The SD-994A-A1SQ delivers 1,000-lb jaw strength, is tested to 500,000 cycles, operates on 8-16VAC or 12VDC, and features corrosion-resistant construction for long-term reliability in indoor access control systems.
The symmetric reversible faceplate measuring 5-7/8 x 1-1/4 x 1/8 inches eliminates the need for separate left-hand and right-hand strike models, allowing a single unit to serve any standard wood door installation. The fail-secure design keeps the strike locked when power is removed, maintaining door security during power outages or system failures.
Where the SD-994A-A1SQ Fits
- Access control systems on wood doors with cylindrical locksets where the electric strike replaces the standard strike plate to enable remote door release, the reversible faceplate fits both left- and right-hand doors without modification, and the 1,000-lb jaw strength secures the door against forced entry
- Fail-secure installations requiring locked-on-power-loss operation where the strike remains locked when power is removed to maintain security during outages, the 8-16VAC or 12VDC operating range connects to standard access control power supplies, and the 500,000-cycle endurance handles high-traffic commercial use
- Indoor commercial and institutional door applications where the corrosion-resistant body withstands daily use in offices, schools, and retail environments, the compact strike depth of 1-1/2 inches fits standard wood door frames, and the 10.3 oz weight installs without reinforcing the frame
What the SD-994A-A1SQ Delivers
- 1,000-lb Jaw Strength: Tested jaw strength of 1,000 pounds resists forced entry attempts and holds the door securely in the locked position. The 500,000-cycle endurance rating ensures reliable long-term operation in high-traffic access control installations.
- Reversible Symmetric Faceplate: The symmetric faceplate measuring 5-7/8 x 1-1/4 x 1/8 inches reverses for both left- and right-hand door installations. A single SKU covers both door orientations, simplifying inventory and eliminating wrong-hand ordering errors.
- Fail-Secure Operation: The strike remains locked when power is removed, maintaining door security during power outages, wiring faults, or system failures. The 8-16VAC or 12VDC operating range with 800mA at 16VAC and 750mA at 12VDC draw connects to standard access control power supplies and controllers.
- Corrosion-Resistant Construction: Corrosion-resistant body and internal components provide long-term reliability in indoor installations. The 3/4-inch latch depth and 21/32-inch keeper depth accommodate standard cylindrical locksets on wood door frames.
