BACnet Sensor Range (BAC)
The Flamefast BACnet sensor range can be supplied with any combination of Carbon Dioxide (CO2), Temperature & Relative Humidity, and the BACnet MS/TP interface allows for the sensors to be integrated with much larger systems over a simple two wire network.
Top Key Features
- 24V AC/DC Power Supply
- Pluggable terminal block for ease of installation
- Optional traffic light readout
- Automatic object configuration
- 3x 0-10V outputs (Network writeable)
- UK Manufactured
Overview
The Flamefast BACnet sensor range can be supplied with any combination of Carbon Dioxide (CO2), Temperature & Relative Humidity, and the BACnet MS/TP interface allows for the sensors to be integrated with much larger systems over a simple two wire network.
With the optional signature Flamefast traffic light display, the sensor can provide a clear, bold indication of the air quality in the monitored space.
As default the three 0-10V outputs will provide a full scale linear output for the CO2, Temp & RH levels, however these analogue outputs can be rescaled or configured to be controlled over the network, negating the requirement for separate local controllers.
There is also the option to assign each of the analogue outputs to any of the sensor values, and the on board relay can be configured to activate based on CO2, Temperature or RH levels, or all can be controlled over the network.
This cost effective and versatile sensor is ideal for any application, including natural and demand controlled ventilation as well as for integrating with our range of gas safety systems.
