Honeywell 301-EMRP-RFSA Remote Panel

The Honeywell 301-EMRP-RFSA Remote Panel is a high-performance gas detection expansion module designed specifically for demanding mechanical and chiller room environments. This unit serves as the direct replacement for the legacy VA301EMRP-RFSA-20 and VA301EMRP-RFSA models, offering seamless integration with the 301-EM controller via a robust RS-485 Modbus communication protocol. Engineered to help facilities meet ASHRAE 15 and B-52 code compliance, this remote panel provides critical visual and audible alerts through its integrated high-intensity strobe and horn, producing 65 dBA at 3 feet to ensure technician safety during refrigerant leaks.

Equipped with a backlit LCD display and an intuitive keypad, the 301-EMRP-RFSA allows for the monitoring of up to twenty zones when networked. The hardware features four DPDT relays (rated 5A at 30 VDC or 250 VAC) and three additional 24 VDC outputs for external accessories. Built into a durable NEMA 1 rated ABS-Polycarbonate enclosure, the panel supports a communication distance of up to 1,000 feet from the main controller using shielded 24 AWG cabling, ensuring reliable refrigerant gas monitoring across large-scale industrial or commercial HVACR footprints.

• Code Compliance: Facilitates meeting ASHRAE 15 and B-52 safety standards for mechanical room gas detection.
• Legacy Compatibility: Engineered as a drop-in replacement for VA301EMRP-RFSA-20 systems, minimizing downtime during upgrades.
• Flexible Alerting: Integrated horn and strobe provide immediate localized notification of alarm levels A, B, or C.
• Industrial Durability: Rugged ABS-Polycarbonate enclosure protects internal electronics in operating temperatures from 32°F to 100°F.
• Advanced Networking: Supports RS-485 Modbus for reliable data transmission over long cable runs up to 1,000 feet.

Is the 301-EMRP-RFSA compatible with older Vulcain controllers?
Yes, it is designed for the 301-EM series and replaces older VA301EMRP models. Ensure your controller firmware is compatible for full feature support.

What type of cable is required for the communication bus?
For optimal Modbus communication and to prevent signal interference, we recommend using twisted and shielded 24/2 AWG cable (such as Belden 9841).

Can I program the alarm thresholds directly on this remote panel?
While the 301-EMRP-RFSA displays status and concentrations, the primary programming and relay logic are typically configured at the 301-EM main controller.
