    Product information for the SECO-LARM SK-1131-SPQ Indoor Illuminated Keypad with Proximity Reader — a full-featured access control keypad supporting up to 1,200 users across 3 outputs, with a built-in 125kHz proximity card reader.

    Key Features

    • Built-in 125kHz (EM125) proximity reader.
    • 4 programmable access modes for all 3 outputs: card only, code only, card + common user code, or card + unique user code.
    • 1,200 users over 3 outputs (codes 4–8 digits): Output #1 – Form C relay, 1A@30VDC, 1,000 users; Output #2 – Form C relay, 1A@30VDC, 100 users; Output #3 – Transistor ground, 100mA@24VDC, 100 users.
    • Outputs can be programmed to activate for up to 99,999 seconds (nearly 28 hours).
    • Super user code for admin access.
    • Up to 50 temporary visitor codes (one-time or limited-time use, 1–99 hours).
    • Programmable egress input with optional warning alarm and delayed egress.
    • Real-time clock to auto-disable access at scheduled times.
    • Duress codes: up to 50 for Output #1, 10 each for Outputs #2 and #3 — trigger a silent alarm if a user is forced to open the door under duress.
    • 12–24 VDC/VAC auto-adjusting operation; all programming done directly from the keypad, no external programmer needed.
    • Mounts to a standard single-gang back box (surface-mount back box included); durable stainless steel faceplate.
    • Tamper output: N.C. dry contact, 50mA@24VDC max.
    • Illuminated keypad with programmable status LEDs (FULL/AUTO/OFF backlight modes).
    • Mantrap mode (only one of two doors open at a time), door-sensor input for anti-tailgating, door-propped-open and door-forced-open warnings.
    • EEPROM memory protects programmed information in case of power loss.
