CH-S

Single Zone Gas Detection Control Hub

Our CH-S Single Zone Control Hub and Remote Sensors are designed to monitor vehicle emissions and control Car Park Ventilation Systems to ensure unparalleled fixed gas detection capabilities.

Available in 24V and 120V with dual gas detection (CO + NO2) built-in or without sensors.

Comprehensive Monitoring

Ensures safety by detecting hazardous hydrogen (H2), carbon monoxide (CO) and/or nitrogen dioxide (NO2) presence.

Greater Coverage

Allows monitoring of a larger area, up to 4 Sensors and 30,000 sq. ft., providing comprehensive surveillance and early detection.

More Control

Offers flexibility and customization options with user-adjustable setpoints, delays, outputs, and relays, along with manual fan activation, allowing tailored responses to varying conditions.

Enhanced Durability

Provides resilience against weather elements with rainproof water resistance and offers simple service and maintenance procedures, ensuring longevity and reliability.

Simplified Installation

Streamlines the installation process with preconfigured wiring, factory calibration, and customized programming, reducing setup time and complexity.

Effortless Upgrade

Seamlessly integrates with both new and existing building control systems, facilitating easy upgrades without significant infrastructure changes.
