Seco-Larm SK-1011-SDQ Indoor Access Control Keypad, 1000 Users, 1A Relay Out, 12-24 VAC/VDC

The SECO-LARM SK-1011-SDQ is a reliable, feature-rich indoor access control keypad designed for easy installation and everyday security.

It supports up to 1,000 user codes plus 50 temporary visitor codes, which can be programmed for one-time or limited-time use. The keypad works with both 12–24 VAC or VDC power, making it flexible for integration with a wide range of access control setups.

The unit provides a Form C relay output rated at 1 A @ 30 VDC, programmable from 1 second up to 99,999 seconds (nearly 28 hours). It also includes a tamper output (N.C. 50 mA @ 24 VDC max) and a push-to-exit input for convenient egress control.

All programmed data is stored in non-volatile EEPROM memory, so settings are retained even during power loss. The SK-1011-SDQ mounts easily into a single-gang back box (flush or surface) and includes a bright backlit keypad for visibility in low-light areas.

Other key features include:

• Wrong-code lockout for added protection

• Real-time clock for scheduled access

• Data I/O for integration with external devices

• Full programming directly from the keypad—no external programmer needed

Operating temperature ranges from -4 °F to 158 °F (-20 °C to 70 °C) with humidity tolerance up to 95% non-condensing. Compact dimensions (4-5/8″ × 2-7/8″ × 1-½″) make it ideal for both retrofits and new installations.
