Seco Larm hl-951r1-sq 900mhz Rf Receiver 1800ft

Product Description

The SECO LARM hl-951r1-sq is a single-channel 900MHz RF receiver designed for wireless control applications requiring long-range, reliable signal reception. Operating in the 900MHz band with digital modulation, it delivers improved interference immunity and stronger signal penetration in environments with heavy obstructions. The unit supports a line-of-sight range of up to 1,800 feet (550 meters), making it well suited for large properties, commercial lots, and industrial facilities where standard-frequency receivers fall short. Installation is handled by licensed low-voltage technicians or security system integrators.

This receiver is part of the SECO LARM ENFORCER HL-Series and is paired with compatible HL-Series 900MHz RF transmitters. The 900MHz operating frequency provides better obstacle penetration compared to 433MHz and 315MHz alternatives, which makes it a practical choice for gate access, door control, and other wireless activation systems in residential, commercial, and light industrial settings. Its single-channel configuration suits straightforward one-device control applications.

Key Features

• 900MHz digital modulation for improved interference rejection and signal penetration
• Single-channel RF receiver for wireless activation control
• Up to 1,800-foot line-of-sight range for long-distance applications
• Designed to pair with SECO LARM ENFORCER HL-Series 900MHz transmitters
• Suited for gate control, door access, and wireless relay activation

Compatibility

Designed for use with SECO LARM ENFORCER HL-Series 900MHz RF transmitters. Confirm transmitter and receiver series compatibility before installation, as 900MHz HL-Series components are not interchangeable with other SECO LARM frequency lines.

Installation Notes

Installation should be performed by a qualified low-voltage technician or licensed security system integrator familiar with RF access control systems. Power down all associated control equipment before wiring the receiver to any relay or control panel input. Mount the receiver in a location that maximizes line-of-sight distance to the transmitter and minimizes physical obstructions between the two units. Follow all applicable local electrical codes and manufacturer wiring guidance during installation.
