Liftmaster Monitored Wireless Edge Kit NEMA 4X (Sentex)
The Sentex Liftmaster LMWEKITU kit is designed to meet 2016 UL 325 requirements and features innovative low-energy Bluetooth transmission with a long range of up to 130 feet. It includes integrated diagnostics and installation protections for up to eight entrapment points. The receiver accepts up to four transmitters, while the transmitter supports up to two wired resistive edges. This configuration supports robust monitoring for residential and light commercial gates, offering reliable edge sensing paired with Bluetooth simplicity for setup and maintenance.
Liftmaster Monitored Wireless Edge Kit (FAS)
This Liftmaster LMWEKITU kit from FAS focuses on wireless edge sensing with a multi-channel Bluetooth transmission system that eliminates interference and provides a reliable 130-foot range. The package typically includes a wireless edge receiver and transmitter, designed for easy installation with minimal wiring. Its modular approach supports expanding edge points as needed, making it suitable for gateways with multiple safety edges or doors that require a monitored edge system for enhanced safety.
Linear SGEKDC Safety Edge Kit
The Linear SGEKDC kit is a UL325-compliant option for gate applications, featuring one SGET transmitter and one SGER receiver. It supports two channels for up to two edges and transmitters per receiver. The receiver operates on 12-30 VDC and includes two output relays for wiring to gate controls. A low battery alert is provided before failure, ensuring ongoing safety coverage for monitored gates, including termination at 10K during normal conditions and a shorted state during sense or power failure.
Miller Edge MWRT12 Wireless Kit
The Miller Edge MWRT12 kit includes a single-channel receiver (MWR12) and transmitter (MWT12). Batteries are included, and the transmitter has a nominal response time of 30 milliseconds. Operating at 318 MHz, the system offers a maximum range of up to 100 feet under optimal conditions. This compact kit is suitable for straightforward gate edge sensing with reliable performance in a smaller installation footprint.
INSL24UL-MC DC Edge Guard Kit
The INSL24UL-MC kit targets industrial-grade operations, suitable for heavy-duty gate systems up to 2200 pounds and 70 feet in length. It includes a complete edge guarding ecosystem with a S505AL Edge Guard and LMRRUL retro-reflective photocell for enhanced safety and functionality. The package lists two remotes (811LM), a KPW250 wireless keypad, and gateway components, with a goose neck pedestal and MRIN riser kit to support rugged outdoor installations. This kit is designed for demanding environments where safety-critical edge detection must perform under challenging conditions.
Buying Guide: Key Considerations For Wireless Safety Edge Kits
- UL325 Compliance: Confirm the kit is UL325-compliant to ensure the edge devices meet safety standards for automatic gates and door operators.
- Range And Interference: Consider the environment; Bluetooth-based systems can offer robust performance up to about 130 feet, while other frequencies may encounter interference in dense settings.
- Monitored vs Non-Monitored: Monitored edge kits provide status signals and diagnostics, reducing the risk of undetected edge failures. Non-monitored kits may be simpler but offer less visibility into edge health.
- Edge Points And Channels: Evaluate how many entrapment points you need to cover and how many channels the receiver supports for multiple edges.
- Power And Wiring: Some kits are battery-powered or DC-powered with 12-30 VDC receivers. Assess compatibility with your gate operator’s power supply and wiring constraints.
- Environmental Durability: For outdoor installations, choose kits with weather-resistant enclosures (e.g., NEMA ratings) and components rated for outdoor use.
- Diagnostics and Alerts: Look for systems offering battery status, fault detection, and remote diagnostics to simplify maintenance.
- Compatibility: Verify compatibility with your specific gate operator model and existing safety devices like photocells or reflectors.
- Expansion Potential: If you anticipate future expansion (more edges or additional sensors), select a kit with scalable transmitter/receiver configurations.
- Installation Complexity: Some kits come with pre-wired edge supports and simple mounting options; others may require more extensive wiring or professional installation.
When evaluating these wireless safety edge kits, buyers should weigh the balance between installation simplicity, safety coverage depth, and long-term maintenance. The five highlighted options provide a spectrum from compact residential kits to heavy-duty industrial configurations, each with distinct strengths in monitoring, range, and compatibility with gate operators.
