Description
Introducing the SK-4131-SPSQ Split Series Keypad with Proximity Card Reader—a rugged indoor access control solution that combines card, code, or both for secure entry. Built for commercial environments, its vandal-resistant stainless-steel faceplate and split-controller design deter tampering while delivering flexible, reliable authentication.
- 3‑in‑1 access method: supports proximity card, PIN code, or a combination of both for versatile authentication.
- Split‑Series security: keypad and controller are physically separate to prevent tampering through the keypad path.
- Vandal‑resistant construction: heavy-duty stainless-steel faceplate with a coated backing to endure demanding indoor usage.
- Voltage and power: 12–24 VDC auto-adjusting operation; built-in 750 mA power supply for the keypad.
- User and card capacity: up to 1,000 codes and/or proximity cards for output #1; 100 codes/cards for outputs #2 and #3; supports up to 50 temporary visitor codes for output #1.
- Relay outputs: Output #1 Form C relay (5A @ 24VDC max); Outputs #2 and #3 Form C relays (1A @ 24VDC max); programmable activation up to 99,999 seconds.
- Tamper and security features: tamper output NC dry contact; anti-tailgating with door sensor input; interlock input for mantrap applications.
- Programmability: all features programmed directly from the keypad; no external programmer required; EEPROM memory preserves settings during power loss.
- Alerts and visibility: keypad illuminates on press with backlight programmable to FULL or AUTO in standby; built-in door chime for audible feedback.
- Mounting and installation: designed to mount to a standard single-gang back box; surface-mount back box included for flexible installation.
- Advanced access control: programmable egress input with optional warning alarm and delayed egress; door sensor input for anti-tailgating; interlock input for a second keypad (mantrap readiness).
- Connection: simple three‑wire connection between keypad and controller for reliable signaling.
- Duress codes: up to 50 duress codes for output #1; 10 duress codes for outputs #2 and #3.
The SK-4131-SPSQ is ideal for office buildings, secure laboratories, healthcare facilities, warehouses, and multi-tenant environments where robust physical security and flexible access control are essential. Use cases include granting temporary access to contractors with time-limited codes, deploying separate door controls across zones via multiple outputs, and implementing mantrap configurations for enhanced perimeter security. Its durable build, intuitive keypad programming, and EEPROM-protected data make day-to-day security management straightforward while delivering peace of mind for facility managers and security teams.
