Honeywell 301-EMRP Remote Panel

The Honeywell 301-EMRP Remote Panel functions as a critical centralized monitoring and control hub for Honeywell 301-EM and 301-EM-20 controllers. Designed for commercial mechanical rooms and chiller plant gas detection, this panel provides real-time status updates via a high-visibility back-lit LCD and localized acoustic alarms. Featuring four programmable SPDT relays and three 24VDC outputs, it allows technicians to trigger remote strobes, exhaust fans, and horns from a distance. Communicating over a robust RS-485 Modbus connection up to 2,000 feet from the main controller, it’s a direct replacement for VA301EMRP and VA301EMRP-20 models. This gas detection remote display ensures compliance with ASHRAE 15 and B52 standards by providing a clear safety interface outside the monitored space, allowing for rapid diagnostics of refrigerant leak detection systems without entering potentially hazardous environments.

Key Benefits:

• Universal Compatibility: Works seamlessly as a drop-in replacement for legacy VA301EMRP-20 and current Honeywell 301-EMRP series hardware.
• Expanded Control Logic: Includes four internal relays to manage auxiliary HVAC ventilation or safety shutdowns based on gas concentration thresholds.
• Long-Distance Monitoring: Utilizes RS-485 daisy-chain architecture to extend monitoring capabilities throughout large facilities.
• Visual/Audio Alerts: Integrated 65dBA buzzer and backlit display provide immediate notification of low/high alarm levels and system faults.

Common Questions:

Can I use this unit to control fans directly?
Yes, the 301-EMRP includes four Form C relays rated for 5A at 250VAC, allowing for the direct integration of ventilation fans or external signal strobes.

Does this panel replace the main 301-EM controller?
No, this is a remote annunciator panel. It must be networked to a Honeywell 301-EM controller to receive sensor data and function as a secondary interface.

How many remote panels can be connected to a single system?
A standard 301-EM network typically supports multiple remote panels, provided the total distance does not exceed the RS-485 signal limits and power requirements are met.
