SPS-31 Fire Alarm System

SPS-31 Fire Alarm System is a computer-aided analogue addressable system designed for collecting and processing data and automatic detection of fire and pre-fire situations, indication of alarm and warning signals on built-in TsPI, VPI, PSI-1 (2) displays and transmitting them to external circuits, as well as transmitting current information on fire-hazardous situation in monitored premises to interfaced devices with generation of recommendations for crew acting in fire situation.

The system includes:

  • TsPI Central Information Panel;
  • PSI-1 and PSI-2 data collecting and processing devices;
  • VPI external indication panel;
  • P-220, P-380 power supply units;
  • addressing device with intrinsically safe circuit for sensor power supply;
  • various types of sensors;
  • PV-D actuation unit control device.
