Overview

The new Duct mounted Smart Sensor from Flamefast Controls is one of the most versatile sensors available, with unrivalled levels of flexibility and a wide range of network writable inputs and outputs, effectively doubling up as a controller.

With the ability to accurately monitor Carbon Dioxide (CO2), Total Volatile Organic Compounds (TVOC), Temperature and Relative Humidity, you can monitoring multiple parameters discretely in return air ducts, without the need for multiple devices.

BACnet and Modbus are provided as standard, as are two 0-10V inputs to allow monitoring of external devices with an analogue output. With the optional I/O module, the Smart Sensor can also provide 3x 0-10V outputs, 1x Digital Input and 1x Relay Output, all of which are network writable, so can be driven remotely to control a wide range of HVAC systems
