    Specifications for the SECO-LARM SK-1123-SDQ Vandal Resistant Outdoor Access Control Keypad — a weatherproof (IP66), 1,100-user, dual-output keypad with anti-tailgating, duress-code, real-time clock, and mantrap features, all programmable directly from the keypad.

    Overview

    The SK-1123-SDQ supports 1,100 users across two Form C relay outputs (1,000 users on Output #1, 100 on Output #2), with 4~8 digit codes. Every feature — including duress codes, temporary visitor codes, scheduled access, and anti-tailgating — is programmed directly at the keypad, with no external programmer required.

    Key Features

    • 1,100 users over 2 outputs; codes may be 4~8 digits
    • Output #1 — Form C relay, 1A@30VDC, 1,000 users; Output #2 — Form C relay, 1A@30VDC, 100 users
    • Outputs programmable to activate for up to 99,999 seconds (nearly 28 hours)
    • Super user code gives admin access to the keypad
    • Up to 50 temporary visitor codes (01~50), programmable for 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 specific times
    • Up to 50 duress codes for Output #1 and 10 for Output #2 — signals a silent alarm under duress
