CH-M

Multi-Zone Gas Detection Control Hub

Our CH-M Multi-Zone Control Hub is designed to monitor any size area for vehicle emissions and control Car Park Ventilation Systems to provide the ultimate fixed gas detection system.

Limitless Possibilities

Offers complete flexibility with fully configurable zones, relays, setpoints, delays, and outputs, allowing customization to specific requirements. Additionally, the system’s scalability via relay expansion packs enables easy expansion as needs grow.

Increased Control

Provides advanced control options, including on-demand ventilation control based on gas concentration, timer schedules, or user input through a 7” full-color LCD touch screen interface.

Maximum Detection

Offers extensive monitoring capabilities by supporting up to 128 CO and/or NO2 sensors, ensuring comprehensive coverage and detection of potential hazards.

Enhanced Durability

Ensures resilience against harsh environments with NEMA 4X water and dust resistance rating, providing long-term reliability even in challenging conditions.

Intelligent Connectivity

Facilitates seamless integration with Building Management Systems (BMS) through BACnet IP and Modbus RTU communication protocols, enabling centralized control and monitoring.

Simplified Installation

Streamlines the installation process with customized factory programming and configuration for every job, reducing setup time and ensuring optimized performance from the start.
