Integrated Automatic Fire-Extinguishing System


Integrated automatic fire-extinguishing system (AFES) is intended for fire protection automation for pump stations and tank farms.

Protected Facilities

  • reservoirs of up to 50000 m3;
  • pump station premises.

Actuated equipment

  • fire water tanks;
  • foam dosing tanks;
  • water and foam supply pumps;
  • valves;
  • light and audio alarm systems;

Main Features

  • reception of electrical signals from manual and automatic fire detectors with indication of number of the activated sensor or fire loop;
  • monitoring of manual annunciator loops operability along their whole length with automatic detection of a break or short circuit;
  • automatic release of fire extinguishing agent to the protected object (actuation of the necessary pumps and opening of shutoff valves);
  • delaying of fire extinguishing agent release to the premises where people are possibly located;
  • shutdown of automatic actuation of the fire fighting equipment with keeping the possibility of local (manual) actuation;
  • automatic monitoring of operability of operational unit electric circuits, circuits of the warning system and sensors of technological parameters;
  • automatic monitoring of levels in fire water and foamer tanks;
  • switching of warning (light/audio) of fire at a protected object;
  • visualization of all operating procedures, state of annunciators or fire loops, current values of monitored parameters on operator's workstation screen or fire post operator's panel;
  • storage and displaying of operations and history logs for the indicated period at operator's workstation or operator's panel.


AFES has centralized architecture on the basis of PLC with CPU hot redundancy feature. Redundant data communication channels with conversion to optical fiber medium are used to provide communication between system elements. Scanning of fire detectors and annunciators is realized on the basis of dust-ignition-proof construction MS-AP signalling devices in Exd case or ia level circuit, which allows for considerable reduction of cabling due to approximation of intellect to a controlled facility. Upper level or the system is realized on the bases of redundant input/output servers.


  • Flexibility

The system can be completed by modules allowing solving different fire protection tasks. Additional protected zones and fire fighting algorithm can be added without PLC reprogramming, using service functions provided by the system.

  • Functionality

The system components provide for additional operation modes (simulation, testing and masking) and other features, such as unauthorized access protection and event logging to monitor personnel actions.

  • Compatibility

AFES features compatibility with an array of industrial controllers from various vendors.
