The SECO‑LARM SK‑910RD2‑4 is a 2‑channel RF receiver with dual‑frequency (433.92MHz and 315MHz) support, compatible with all ENFORCER SK‑series transmitters. It runs on 10‑24 VAC/VDC, features two 10A Form C relays, 5 output modes per channel, and stores 15 codes per channel with a 500ft (150m) range (1000ft with optional antenna).
• Operating frequency: 433.92MHz (315MHz with SK-91ERSD antenna)
• Channels: 2 independently programmable
• Memory capacity: 15 transmitter codes per channel
• Relay contacts: 2 × Form C, 10A @ 14VDC
• Operating voltage: 10-24 VAC/VDC
• Current draw: 16mA standby / 60mA active @ 12VDC
The SK‑910RD2‑4 is a 2‑channel RF receiver for remote control of doors, gates, lighting, lifts, and other devices. It supports simultaneous 433.92MHz reception and 315MHz reception (the latter requiring the SK‑91ERSD Extended Range Antenna). Standard range is up to 500 feet (150m) and up to 1000 feet (300m) with the optional antenna, compatible with all ENFORCER SK‑series transmitters.
Two independently programmable channels offer 5 output modes each: timed pulse (0.5‑99 sec or 1‑99 min), toggle, latch, and follow (validity). Each channel features a 10A Form C relay (NO/NC/COM) for direct control of electric strikes, magnetic locks, or motors, with a 2‑digit 7‑segment LED display for status indication and screw terminals for secure wiring.
Pushbutton programming simplifies transmitter pairing with no jumpers or switches, storing up to 15 codes per channel. The unit measures 107 × 23 × 60 mm, operates from 0°C to 75°C with 5‑95% RH, and is powered by 10‑24 VAC/VDC (16mA standby, 60mA active).
