2-Button 900MHz Long Range Remote Control with 3 Channels, 5 Output Modes, and IP68 Waterproof Housing
The Seco-Larm HL-951T2-SQ is a 2-button, 3-channel 900MHz RF transmitter that provides long range wireless control up to 1,800 feet (550 m) line-of-sight for gate operators, door strikes, barriers, lighting, and relay-based automation. The dual buttons give independent control over two devices or trigger both simultaneously on a third channel, and five individually programmable output modes let installers configure each channel for momentary, latching, timed, or conditional operation through the paired HL-Series receiver. The IP68 waterproof housing and internal PCB antenna make the transmitter durable enough for daily outdoor use in security and access control installations.
The HL-951T2-SQ uses advanced digital modulation with over 20 nonillion possible code combinations, making the signal virtually impossible to intercept or clone. Each channel supports up to 99 programmed button codes, so a single HL-Series receiver can manage access for up to 99 users per channel without a separate access control panel. Switch-based programming (no jumper cuts required) and a built-in RF signal strength test mode simplify installation and site verification.
Where the HL-951T2-SQ Fits
- Multi-device gate and door control where one button opens the main gate and the second button controls a pedestrian gate, garage door, or secondary entry point, all from a single transmitter in the vehicle or on a keychain
- Commercial parking and access systems where up to 99 transmitters per channel can be enrolled on a single HL-Series receiver, providing managed access for tenants, employees, or authorized vehicles without additional controller hardware
- Wireless automation triggers where each button activates a different relay output for lighting, irrigation, signage, or alarm functions, with five programmable output modes giving full control over how the receiver responds to each press
What the HL-951T2-SQ Delivers
- 1,800 ft (550 m) line-of-sight range: The 917MHz frequency delivers long range signal transmission with strong obstacle penetration. Internal PCB antenna eliminates breakable external parts and maintains consistent RF performance.
- 2 buttons, 3 channels, 5 output modes: Button 1 and Button 2 each control their own channel, and pressing both simultaneously activates a third channel. Five programmable output modes per channel (set at the receiver) cover momentary, latching, timed, and conditional responses.
- 99 transmitter codes per channel: The paired HL-Series receiver stores up to 99 unique transmitter codes per channel, making it practical for multi-user gate and parking access without a separate access control panel.
- IP68 waterproof with LED indicator: Fully sealed housing rated for submersion. The LED indicator confirms transmission and assists with programming and signal strength testing during installation.
- 20+ nonillion code combinations: Advanced digital modulation generates over 20 x 10^30 possible codes, making the transmission immune to code grabbing and brute force attacks used against consumer-grade rolling code systems.
