Duct Smart Sensor (DSS)

The new 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.

Top Key Features

  • BACnet and Modbus as standard
  • 24V AC/DC Power Supply
  • Pluggable terminal block, with two 24V and 0V connections for ease of termination
  • Optional multi colour display based on CO2 & TVOC levels (network writable)
  • UK MANUFACTURED

Overview

The new 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.

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.

With capacitive touch sensors providing either 1, 2 or 3 buttons on the front, the units can be fully configured to provide Temperature Set Point Adjust, Boost, and Fan Control facilities.

With the optional signature Flamefast multi-colour display, the sensor can provide a clear, bold indication of the air quality in the monitored space.
