HONEYWELL RANGE2000 Gas Detection System

🧾The HONEYWELL RANGE2000 is a fixed refrigerant-gas detection system from the Honeywell gas-detection portfolio, designed for continuous leak monitoring of refrigerants — primarily ammonia (NH3) in refrigeration plants, cold stores, food processing and chiller rooms — with alarm and ventilation interlock outputs.

• ✔Fixed refrigerant-gas detection system
• ✔Continuous monitoring of refrigerant leakage — primarily ammonia (NH3) applications 
• ✔Controller-based architecture: central control unit with remote gas sensors
• ✔Standard 4–20 mA sensor signal interfacing
• ✔Multi-level alarm outputs for ventilation / shutdown / alarm annunciation
• ✔Suited for refrigeration plants, cold stores, food processing and chiller rooms
• ✔Honeywell gas detection portfolio 

• ✔Product Line: Honeywell
• ✔System Type: Fixed gas detection / refrigerant leak detection
• ✔Target Gases: Ammonia (NH3); other refrigerant gases 
• ✔Architecture: Central control unit + remote sensors
• ✔Sensor Signal: 4–20 mA
• ✔Alarm Outputs: Multi-level alarm / relay outputs
• ✔Application: Refrigeration, cold storage, food processing, mechanical rooms

• ✔Install sensors at refrigerant-leak-prone locations (near valves, flanges, compressor rooms) per the system layout and applicable standards (e.g. EN 378 / safety codes for ammonia plants).
• ✔Mount the control unit in a protected area; route sensor cables separately from power conductors with proper shielding.
• ✔Configure alarm setpoints (pre-alarm / alarm levels) according to the plant's risk assessment and local regulations.
• ✔Verify the ventilation and shutdown interlock wiring during commissioning — alarm outputs must trigger the intended actions.
• ✔Perform periodic sensor calibration (zero/span) and bump tests per the maintenance schedule to maintain detection reliability.
