Modules and batteries for automatic gas fire extinguishing, models: MPGT – 40 “SMD” (65-40-32), MPGT – 50 “SMD” (65-50-32), MPGT – 60 “SMD” (65-60-32) , MPGT – 70 “SMD” (65-70-32), MPGT – 80 “SMD” (65-80-32), MPGT – 90 “SMD” (65-90-32), MPGT – 100 “SMD” (65-100-32), MPGT – 120 “SMD” (65-120-32), MPGT – 80 “SMD” (65-80-50), MPGT – 100 “SMD” (65-100-50), MPGT – 120 “SMD” (65-120-50), MPGT – 140 “SMD” (65-140-50), MPGT – 150 “SMD” (65-150-50) (hereinafter referred to as modules), as well as batteries that include the same type of MPGT modules and are connected by a common collector (hereinafter referred to as batteries).
According to the method of storage, GFFS are divided into modular and centralized (a group of modules assembled into a battery and connected to a common manifold. Modules and batteries refer to components of automatic fire extinguishing systems and are used for storing GFFS with a further automatic or remote or local launch method when class fires occur A, B, and E electrical equipment with a voltage not higher than permissible for a gas fire extinguishing agent.
Modules and batteries are operated and operational at ambient temperatures from minus 20°C to plus 50°C, climatic version UHL (NF) category 4, atmosphere type II, III according to GOST 15150-69.
Modules and batteries are manufactured in accordance with the requirements of these technical specifications TU 26.30.50-771-81888935-2023 “Modules and batteries for automatic gas fire extinguishing”, EAEU TR 043/2017 “On requirements for fire safety and fire extinguishing means”, SP 485.1311500. 2020, GOST R 53281-2009, GOST 12.2.003-91, GOST 12.2.007.0-75, GOST 12.3.046-91, GOST 15150-69 vessels used for storing GFFS must meet the requirements of TR CU 032/2013 Technical Regulations of the Customs Union “On the safety of equipment operating under excess pressure” according to design documentation approved in the prescribed manner.
The modules are designed for long-term storage and release of gas extinguishing agent in the event of a fire in a building (premises) or structure.
A group of modules combined into a single battery is intended for the centralized storage of a large volume of fire fighting fuel with the subsequent release of fire fuel in the event of a fire in large areas
The modules are used to extinguish class A, B and E fires of energized electrical equipment (the voltage at which it is possible to extinguish without shutting down the protected equipment must comply with the requirements of the normative and technical documentation for fire safety equipment).
The method of storing GFFS is modular or centralized.
The batteries have the ability to be connected to a single pipeline manifold, forming a centralized GFFS storage point.
Modules and batteries are used for fire protection of premises and equipment in a modular design for volumetric or local volumetric fire extinguishing.
Modules and batteries are classified as recoverable and serviceable technical products.
The design of modules and batteries meets the seismic resistance requirements in accordance with GOST 30546.1-98, GOST 30546.2-98 and GOST 30546.3-98 and has a design of 9 points on the MSK-64 scale.
Service life from the date of manufacture is no more than 30 years.
