With the Sita 200 plus system a high technology approach has been adopted, with a microcomputer in each detector implementing a large degree of distributed intelligence. The system can support 200 Multipoint combined detector/sounders on a single loop. Each one not only provides detection, but also the option of a built in sounder. Integrity of the system is maintained by way of a built-in isolator in each device. Sita system intelligence has been harnessed in such as way that it equipment used is very easy to install, commission and maintain.

The system has been designed to high specification and quality standards, and is intended to fully comply with new EN54-2 and EN54-4 standards and EU directives.


  • Fast short circuit isolator in every device
  • 15 combinations of smoke & heat detection modes
  • Multi stage alarms - pre alarm feature
  • Auxiliary digital inputs and outputs are available at any Addressable Multipoint device
  • Automatic continuous calibration
  • Addressable Multipoint detector is monitored for all failures of sensor chamber - warning is indicated when a smoke detector head requires servicing
  • Maintenance is easy with the unique disposable optical chamber, designed as a cost effective solution to cleaning and re-calibration.

All modes are compliant with European detection type specifications, and are suitable for use in installations compliant with BS5839 : Part 1 :2002
