Seco Larm hl-951t1-sq 1-button 917mhz Rf Transmitter

Product Description

The SECO LARM hl-951t1-sq is a single-channel, 1-button RF transmitter operating at 917MHz in the HL-Series product family. Designed for access control and remote activation applications, it generates over 20.28 nonillion possible codes, making code-cracking or accidental code duplication effectively impossible. The unit supports a wide input voltage range of 10 to 24 VAC or 9 to 48 VDC, giving installers flexibility across a broad range of control panel configurations. A built-in PCB antenna eliminates any external antenna that could be adjusted, vandalized, or damaged in the field. Licensed electricians and access control technicians are the primary installers for this device.

This transmitter fits residential and light commercial access control systems where a compact, weather-resistant RF trigger is needed. Its waterproof IP68 rating makes it suitable for outdoor mounting locations exposed to rain, moisture, or wash-down conditions. The unit supports up to 99 button codes per channel and offers five individually programmable output modes, allowing one device to serve a variety of activation scenarios. A built-in RF signal strength and site survey test mode helps technicians identify the optimal installation location before final mounting. It is compatible with all HL-Series transmitters of the same 917MHz frequency.

Key Features

• 917MHz operating frequency with over 20.28 nonillion possible codes to prevent code duplication or cracking
• Wide voltage input: 10 to 24 VAC or 9 to 48 VDC for multi-application compatibility
• Waterproof IP68 rating for outdoor and harsh-environment installations
• PCB antenna — no external antenna required, adjusted, or exposed to damage
• Five individually programmable output modes and up to 99 button codes per channel
• RF signal strength and site survey test mode for optimal placement
• DIP-switch programming — no jumper cutting required

Compatibility

Compatible with all HL-Series transmitters of the same 917MHz frequency. A 868MHz CE-compliant version is also available for applicable markets.

Installation Notes

Installation should be performed by a licensed electrician or qualified access control technician in accordance with applicable NEC guidelines. Disconnect and de-energize the control panel before wiring the transmitter to the power source. Use the built-in site survey mode to verify RF signal strength at the intended mounting location before committing to final installation. The IP68 waterproof rating requires that all conduit entries and enclosure seals be properly maintained to preserve the environmental rating.
