Description

The CMD5B4 & 5 Series carbon monoxide detector uses an electrochemical sensor to monitor the carbon monoxide level and outputs a field-selectable 4-20 mA or voltage signal. The voltage signal may be set to 0-5 or 0-10 Vdc.

The sensing range and output may be scaled to either 100, 150, 300, 400 or 500 ppm via the on-board menu. A front panel LCD is standard to ensure easy setup and operation. 

It is available in either wall/surface  or duct mount configurations.

Other standard features include a back light for the LCD, a front panel test switch, status indication and an alarm buzzer. The test function may also be controlled remotely with a digital input signal.  The on-board menu allows local configuration of all device parameters. Optional features include one or two alarm relays and/or RS-485 network communication configured for either ModBus or BACnet protocol.

Options are available to add an LCD Display or Modbus Output instead of Analogue Output. If required, please select from the Recommendations Tab.

This makes it ideal to use with most Data Acquisition Equipment and Data Loggers, or by using the Modbus output straight into a Monitoring System, such as our Orchestrator software.
