Speco Technologies AWRT4 4-Button Long Range Transmitter

Overview

The Speco Technologies AWRT4 is a ruggedized 4-button long-range transmitter designed for professional access control installations. This pack contains 5 complete transmitter units, each featuring proven Digital Ultra High Frequency (UHF) 433 MHz technology for button-press transmission and dual-frequency support for presentation-mode credential reading at 125 kHz or 13.56 MHz. The AWRT4 delivers extended read range capabilities while maintaining compact, field-hardened design suitable for indoor, outdoor, and high-traffic deployment environments.

Key Features

• Extended Read Range: Up to 200 feet (60 meters) for button-press transmission; up to 3.5 inches (88mm) for proximity presentation mode
• Dual-Frequency Technology: 433 MHz UHF for button press, 125 kHz or 13.56 MHz for proximity card reading
• IP65 Weather Resistance: Electronics snap-sealed in weather-resistant polycarbonate enclosure with gray ABS keys; rated for outdoor deployment
• Compact Dimensions: 1.45" W × 2.5" H × 0.56" D (37mm × 63.5mm × 14.2mm), weighing just 0.7 oz (20g) per unit
• Rolling Code Encryption: Secure button-press transmission using rolling code and encryption protocols
• Integrated Red LED: Status indicator activated on button press for user feedback
• Convenient Carry Design: Built-in eyelet for secure attachment to key ring or lanyard
• Long Battery Life: Single replaceable CR2032 lithium 3.3V battery with standard replacement cycle
• Wide Operating Range: Rated -40°F to 122°F (-40°C to 50°C) for year-round deployment in variable climates
• Industry-Standard Wiegand 26-bit Compatibility: Integrates with AWRR44 proximity readers and standard access control platforms
• ETL Listed: Certified under UL-294 standard for Access Control System Units
• Multi-Certification: FCC, ICC, and CE approved; NDAA Section 889 Part B compliant

Integration and Compatibility

The AWRT4 is designed for direct integration with Speco access control readers supporting Wiegand 26-bit protocol. Button-press mode operates on 433 MHz with rolling code encryption, ensuring secure credential transmission over extended distances. Presentation mode supports standard proximity protocols at 125 kHz (Proximity®) or 13.56 MHz (HID iClass®, MIFARE®, and similar). This dual-mode architecture allows deployers to use the transmitter as either a long-range fob or a presentation-style credential reader based on system requirements and facility layout.

Package Contents

Pack includes 5 complete AWRT4 transmitter units. Each unit ships ready to deploy with integrated CR2032 battery installed and eyelet pre-assembled. No additional accessories or configuration required for standard access control installations.

Perspective based on aggregated IP Security Depot and affiliated engineering team experience.

The AWRT4 addresses a specific integration need in access control deployments where standard proximity readers fall short on range or where secured long-distance transmission is required. During evaluation for campus and industrial site deployments, this transmitter performed reliably across both button-press and presentation modes, with the 200-foot range proving particularly valuable for gatehouse and vehicle checkpoint installations.

Technical Highlights:

• Dual-Mode Operation: 433 MHz button press (200 ft range) and 125/13.56 MHz presentation modes eliminate the need for separate credential types in mixed-use environments
• Encryption and Security: Rolling code transmission prevents replay attacks and unauthorized credential replication in sensitive facility access scenarios
• Environmental Durability: IP65 rating and sealed enclosure ensure field reliability in outdoor gate controllers, parking access points, and weather-exposed areas; -40°F to 122°F operating range handles climate extremes

Deployment Considerations:

• Verify reader compatibility with AWRR44 and Wiegand 26-bit protocol before bulk deployment; test presentation frequency (125 vs. 13.56 MHz) against your installed reader base
• The 0.7 oz weight and eyelet design make these ideal for badge-on-lanyard or key-fob mounting in high-turnover environments such as healthcare, hospitality, and logistics operations
• Battery replacement (CR2032) is end-user serviceable; plan for annual replacement cycles in high-frequency use installations

For integrators managing mixed access control environments, the AWRT4 pack delivers proven UHF reliability without proprietary firmware dependencies. Stock the 5-pack for multi-door rollouts and retrofit projects where long-range credentials provide both operational flexibility and future-proof scalability.
