Purpose, composition and main characteristics of the automatic powder fire extinguishing unit

2.1. APCP is designed for automatic detection and extinguishing of fire centers when the controlled fire factors exceed the established threshold values in the protected area. The CPA also notifies the facility personnel and/or fire department about the fire.

2.2. The APCP consists of:

powder fire extinguishing module MPP10007 3 pcs.

powder supply lines, set 3

cable network

equipment for automatic fire detection and starting of modules based on "Dozor16" PPKOP

"Output" annunciator - 3 pcs;

"Leave powder" annunciator - 3 pcs.;

thermal fire detector IP 1034/1IB 16 pcs.;

fire detector manual IPR -3SU 3 pcs;

device for manual electrical starting of URP7 3 pcs.

device for galvanic isolation and provision

"intrinsic safety" of a loop UPKOP of 13511 4 pieces.

2.4. Automatic fire detection and start-up equipment of modules based on "Dozor16" PPKOP is designed to build and monitor the status of alarm loops and start-up circuits, generate indication control signals and external devices, and output starting pulses to fire extinguishing modules.

Characteristics of protected premises

3.1. The following shall be protected:

manual painting chambers - 3 pcs. Dimensions 1.5 * 1.2 * 2m. The area of each chamber is 1.8m2, the volume is 3.6m3. Classification of an explosive zone by PUE - V-1a

paint preparation area, area 15 m2, volume 60m3. Classification of an explosive zone by PUE - V-1a

thermal radiation drying chamber, dimensions 10 * 1.5 * 2m. Possible temperature range 80180so. Classification of explosive area according to PUE - V-1b.

Classification of explosive zone by PUE within a radius of 5 m from open openings of all chambers - V-1b.

Main technical solutions adopted in the project

5.1. In automatic mode PPKOP "Dozor16" performs constant cyclic polling of connected devices, analyzes the status of alarm loops and start-up circuits.

5.2. Loops passing through controlled zones (2 loops each in the zone) are logically combined into fire extinguishing directions:

drying chamber thermal radiation - direction 1

paint chambers - direction 2

paint preparation area - direction 3.

5.3. When laying alarm loops through explosive areas, the CPCP 13511 device provides galvanic isolation of the loops and the type of explosion protection "intrinsically safe circuit."

5.4. In one of 2 alarm loops of each direction, a manual fire detector is included to manually generate the "Attention" signal in this direction.

5.5. At actuation of one fire detector in alarm loop the control equipment of automatic control system generates signal "Attention" with indication of direction in which actuation occurred. Sonic and light annunciators of PPKOP "Dozor16" are switched on. The signal "Attention" is transmitted to the PCP and/or the fire department room of the enterprise.

5.6. When two fire detectors operate in different loops of the same fire extinguishing direction, the control equipment enters the "Fire" state. "Leave powder" light-and-sound annunciator of this direction is ON. Commands for disconnection of supply units and de-energizing of process equipment are generated. If the automatic control system is in the "Automatic on" state, a thirty-second count of the delay in the release of the fire extinguishing agent (the time required to evacuate people) begins.

5.7. Upon completion of thirty-second delay of PPKOP "Dozor16" outputs electric pulse to starting device MPP100.07 of direction in which detectors were activated, opening of membrane occurs, working gas is supplied from cylinder to module housing. After increasing the pressure in the housing to the operating value, the membrane is opened and the fire-extinguishing powder in a fluidized state enters the distribution pipeline and then through the sprayers to the protected area.

5.8. The modules for each fire-fighting direction can also be started manually from PPKOP "Dozor16" or from the manual starting device of URP7.

Attention! Starting from URP7 is performed without delay.

5.9. On the doors to the protected rooms there are contact detectors that turn off the automatic start of the installation when they open. Indication of disabled state is displayed on "Automatic ON" annunciator located in front of inputs to protected rooms.

5.10. Automatic start mode is restored by introduction of code from PKP16 or from monitoring panel of BPN PPKOP "Dozor16."

5.11. Given the presence of high temperatures in the drying thermal radiation chamber and at the request of the customer, explosion-proof fire detectors "Pulsar 2012" are used to detect possible fire centers in the chamber.

5.12. The design of fire extinguishing plants completely eliminates the possibility of the fire extinguishing agent entering the protected room before the plants are activated, which guarantees the safety of personnel in these rooms.

5.13. Fire extinguishing powder by the degree of exposure to the body refers to low-hazard substances of hazard class IY in accordance with GOST 12.1.00776. Irritating effect: on the mucous membrane of the eyes - weakly expressed, on the skin - absent. Powder compositions used are not toxic, do not corrode metals in dry form. After a fire, the powder can be removed with a vacuum cleaner or washed away with water.
