Russian gaseous fire suppression abbreviations explained: AUGPT, MGP, GOTV, ZPU and KSID
AUGPT is the transliteration of the Russian abbreviation for an automatic gaseous fire suppression system. It detects a fire and discharges an extinguishing agent into the room automatically. Designs and product passports also use MGP for a gaseous fire suppression module, GOTV for a gaseous extinguishing agent, ZPU for a valve and actuation assembly, and around fifteen other abbreviations. We have collected them in one table and explained where each is used.
What do gaseous fire suppression abbreviations mean?
The table lists abbreviations commonly found in designs, estimates, module passports and certificates. They appear in the order a customer usually encounters them: the complete installation first, then its equipment, followed by alarm systems and calculations.

This is not an exhaustive list: each equipment manufacturer has its own component designations. If you encounter an unfamiliar abbreviation, check the product passport or the general information section of the design.
What is the difference between AUGP and AUGPT?
There is no technical difference: both refer to the same installation. The final “T” represents the Russian word for suppression. Both forms come from Russian design practice, where AUGP has historically been used. AUGPT is more common in searches: according to Wordstat data for September 2026, it receives 1,493 monthly searches in Russia, compared with 670 for “аугп”.
Use one form consistently throughout a design. This keeps terminology identical in the estimate, specification and as-built documentation, avoiding questions from the acceptance committee about whether they describe the same system.
MUGP refers to a modular gaseous fire suppression installation, a type of AUGPT in which the agent is stored in modules inside or beside the protected room. The alternative is a centralised installation. Its cylinders are assembled into a bank in a separate suppression station, with agent delivered to protected rooms through main pipework and selector valves.
What does an AUGPT consist of and how does it work?
An AUGPT has two parts: fire automation detects the fire and issues the command, and the technical part stores and releases the gas. It includes:
- smoke or heat fire detectors;
- a control panel that triggers warnings and issues the release command;
- warning signs, sounders and a manual release device;
- modules with gas and discharge valves;
- pipework and nozzles; ceiling-mounted modules have the nozzle directly on the valve;
- a pressure relief valve in the room wall.
The system always works the same way. Detectors sense smoke or heat, the control panel switches on the signs and siren, stops ventilation and holds a delay for evacuation. Then the actuator fires, the valve opens and gas fills the room through the nozzles: with halocarbons at least 95% of the design mass is released within 10 seconds. After extinguishing, the room is ventilated and the modules are sent for recharging. The activation stages are described in detail on the home page.
An AUGPT is maintained by an organisation with a permit from the Ministry of Emergency Situations: it checks the system to schedule, monitors the pressure and agent mass in the modules and keeps the maintenance log.
How are these terms named in Kazakhstan’s standards?
Kazakhstan’s standards rarely use abbreviations. In SN RK 2.02-02-2023 (PDF) and SP RK 2.02-102-2022 (PDF) the terms are written in full, and only SOUE is expanded in the terminology section (clause 3.2 of SN RK). GOTV appears just once in each document. When referencing a standard, designers should therefore search for the full term “gaseous fire suppression system installation”, rather than AUGPT.
| Term used in designs and product passports | Term used in Kazakhstan’s standards | Where to find it |
|---|---|---|
| AUGPT (АУГПТ) | Automatic fire suppression system installation; gaseous fire suppression system installation | SN RK, clause 3.49 and section 9 |
| MUGP (МУГП) | Modular fire suppression installation | SN RK, clauses 3.30 and 3.31 |
| Centralised AUGPT | Centralised gaseous fire suppression system installation | SN RK, clause 3.13 |
| MGP (МГП) | Fire suppression module | SN RK, clause 3.58 |
| Cylinder bank | Gaseous fire suppression cylinder bank | SN RK, clause 3.12 |
| Gaseous extinguishing agents | Gaseous extinguishing agent | SN RK, clause 9.1.3; SP RK, table 8 |
| NOK (НОК) | Specified extinguishing concentration, designated сн in the Russian standard | SN RK, clause 9.1.1; SP RK, appendix Д |
| KSID (КСИД) | Pressure relief opening or device | SN RK, clause 9.3.3; calculation according to appendix Е of SP RK |
| PPKP (ППКП) | Fire alarm control panel | SN RK, clause 3.42 |
| PPU (ППУ) | Fire suppression control panel | SN RK, clause 3.7 |
| IPR (ИПР) | Manual fire alarm call point | SN RK, clause 3.25 |
| UDP (УДП) | Remote actuation of the installation | SN RK, clause 3.56 |
The same documents define terms needed for calculations and acceptance. Installation response delay (clause 3.26) is measured from detector activation to the start of agent discharge. Spare extinguishing agent (clause 3.39) is stored on site to restore the installation after actuation. A nozzle (clause 3.62) is the device that releases and distributes the agent.
Where can you find abbreviations in a module passport and a design?
In a module passport, abbreviations appear in the product designation, specification table and component list. Floor-mounted FireStop modules use the designation МГП FS (65-70-40): the first number is operating pressure in kgf/cm², the second is cylinder capacity in litres, and the third is the nominal valve bore in millimetres.
The same table specifies the actuation method. Floor-mounted FireStop modules use ЭМ-Р and П-Р; ceiling-mounted versions use ЭМ-Р and ЭМ-А. ЭМ-А denotes electromagnetic actuation combined with autonomous temperature actuation. The component list includes the cylinder, siphon tube, valve assembly, pressure indicator or gauge, safety device, high-pressure hose and discharge nozzles.
In a design, abbreviations are collected in the general data and in the technological part of the AUGPT section. Under clause 9.1.7 of SN RK 2.02-02-2023, the technological part of a modular system contains information on the modules, distribution pipework and nozzles. The design and specifications of FireStop modules are shown on the pages for floor-standing and ceiling-mounted modules, while FireStop module passports and certificates are available in Documentation.
Frequently asked questions
What does GOTV mean in fire suppression?
GOTV is the Russian abbreviation for a gaseous extinguishing agent: a gas discharged into a room to stop combustion. FireStop modules use HFC-125, HFC-227ea and FK-5-1-12. HFC agents inhibit the chemical combustion reaction, while inert gases and CO₂ reduce the oxygen concentration. Read about their differences in “Which agent should you choose?”.
What does NOK mean in a gaseous fire suppression calculation?
NOK is the specified extinguishing concentration: the percentage of agent in the room volume at which combustion stops. SP RK 2.02-102-2022 designates it сн and lists values for each agent in appendix Д. For example, HFC-227ea requires 7.2% by volume for n-heptane fires. The agent mass in the installation is calculated from this concentration.
How does a gaseous fire suppression module differ from an installation?
A module is a single agent-filled cylinder with a valve and actuation assembly; an installation is the complete system built around it. It includes modules, pipework, nozzles, detectors, control panels, warning signs and alarm devices. A module can operate autonomously, but on site it is usually connected to suppression controls and an alarm system.
What does AGPT stand for?
AGPT is a Russian abbreviation for automatic gaseous fire suppression. It is an informal version of AUGPT that omits the word “installation”. It appears in commercial quotations and on websites. Design documentation should use the full installation name or AUGPT with an explanation on first use.
