Interscan’s AccuSafe consists of up to ten sensor modules reporting to a single controller. Since the communications are Modbus TCP/IP, there is no limit on the distance between sensor modules and the controller. (Modbus RTU is also available.) Each sensor module is provided with an integral sample draw pump, for a quicker and more reliable response. And, data acquisition is built in. No additional software is needed. Temperature and relative humidity sensors are also included. Remote annunciators are also available.

The Sensor Unit can be provided with an integral concentration display and alarm indicators. In this configuration, the Sensor Unit can become a stand-alone gas detector. This is perfect for single-point applications in which a full Controller is not required.

  • Manage multiple controllers over your local network connection
  • Search and view available AccuSafe controllers in your network.  This lets you watch your sensors on your phone—or any authorized device—in real time.  You can also perform any controller function, including calibration and alarm settings.
  • Update controller or sensor unit software
  • Create, backup, and restore control panel configurations
  • Download recorded sensor data from any controller
  • Configure MQTT communication settings
  • AWS (Amazon Web Services) Web Control option.
