H-300 Series Gas Detectors

HVAC-R and Commercial Application

The H-300 line of addressable gas detectors provides a flexible solution for centralized monitoring of refrigerant gasses in residential or commercial spaces such as hotels, hospitals, apartment complexes and etc. It features a selection of fixed point detectors, available for A1, A2 and A3 refrigerants.

H-300 detectors are engineered to function seamlessly as a one-stop autonomous solution or a reliable field-level element of our advanced addressable systems. They offer an addressable (Modbus RTU) output option and two integrated SPDT relays.

The detectors are simple to install and maintain. The high-visibility light indication and local sound signalization allow for easy status monitoring, while the Modbus RTU communication offers real-time configuration and data monitoring on the supervisory level via BMS or HMI. All H-300 detectors are equipped with a self-diagnostic function, which constantly monitors the condition of the sensor and signal lines, and alerts in case of fault. 

Benefits:

  • Flexibility: The H-300 line of addressable gas detectors provides easy integration, regardless of project size. Power the H-300 detector locally (230VAC) or via the Modbus serial line (15-30VDC) to minimize cabling expenses and optimize installation layout. Use the two integrated SPDT relays to operate automation on the field level, while also taking full advantage of our addressable system functionality and modular architecture.

  • Cost-effective specification: H-300 detectors are designed to deliver maximum value and reliability. With a low initial investment, they effectively reduce project costs. Additionaly, the simplified calibration procedure and self-monitoring technnology streamline the maintenance process and result in substantial savings.
