Introduction
Integrated automatic fire extinguishing system (AFES) is
intended for fire protection of oil filed facilities.
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;
- Loop and flow line closing control;
- 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;
- Automatic monitoring of pressure in starting bottles, automatic
control of fire extinguishing agent weight for the
gas-extinguishing installations;
- 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.
Integrated automatic fire extinguishing system has centralized
architecture on the basis of programmable logic controllers.
Scanning of fire detectors and annunciators is realized on the
basis of dust-ignition-proof construction MS-AP signaling devices
in Exd case or ia level circuit, which allows for considerable
reduction of cabling due to approximation of intellect to a
controlled facility.
Benefits
The system can be completed by modules allowing solving
different fire protection tasks. Additional protected zones and
fire fighting algorithm can me added without PLC reprogramming,
using service functions provided by the system.
AFES is compatible with all types of fire alarm boxes.
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.
AFES features compatibility with an array of industrial
controllers from various vendors.
The system has all the necessary fire safety certificates and
permits for use of Rostehknadzor.
