1.3 FUNCTION OF THE EXTINGUISHING SYSTEM
The ARMANfire System is designed as a fixed fire suppression system, where the extinguishing agent
is stored in a pressurised vessel with nitrogen at an operating pressure of 18 bar. The nitrogen acts
as the propulsion gas expelling the extinguishing agent, as well as compensation for natural micro
leakages over time. The valve of the vessel is maintained shut by external pressure coming from
the Easydetect sensor tube.
The Easydetect sensor tube is a linear thermal detector mounted inside a defined enclosure (LPCB
certified volumes of up to 2m3) covering all risks within it to ensure rapid fire detection. If a fire
occurs in the enclosure, the sensor tube that is pressurised with nitrogen, (18 bar internal pressure,
as in the pressurised vessel) bursts due to the continuous heat rise. After it occurs, the extinguishing
agent is discharged from the same hole that the fire has produced in the Easydetect sensor tube.
Enclosures may only be operated with a properly installed and fully functional
extinguishing system so to avoid fire propagation to adjacent enclosures in case of a
fire.
Notes to take into consideration regarding ARMANfire systems:
• Regular visual inspections of the vessel pressures on the pressure gauges ensure the system
function and operation outside the service intervals.
• The extinguishing agent is clean agent in gaseous form when discharged, FK-5-1-12, it is
colourless, odourless and electrically non-conductive. It is non-toxic and leave no residue
upon discharge.
• The main extinguishing mechanisms of clean agent is by removing enough heat from the
fire and interrupting the combustion chain reaction.
1.4 DIRECTIVES FOR USERS OF THE SYSTEM
1.4.1 INSTALLERS AND SERVICE PERSONNEL

2.2 APPLICATION LIMITS
Direct low-pressure application fixed fire suppression system, ARMANfire, is used for the protection
of small unoccupied defined enclosures such as electrical switchgear cabinets, server racking
and similar installations from small local flaming fire sources. The system uses a single method of
detection and delivery of the extinguishing agent to the fire ignition point., called Easydetect
tubing, a heat sensitive pneumatic detection tubing.
The ARMANfire system is intended solely to provide improved local fire protection that may occur
within enclosures of a defined volume and prevent possible fire propagation to adjacent
enclosures. It is not intended for use as whole room or building fire protection system. To guarantee
complete fire protection always, applicable fire safety codes shall be followed.
Limitations in the use of FK-5-1-12 extinguishing agent:
Agents may be used for extinguishing fires of all classes within limits. Unless relevant testing has
been carried out to satisfaction, FK-5-12 shall not be used on fires involving:
a) Chemicals containing their own supply of oxygen, such as cellulose nitrate;
b) Mixtures containing oxidizing materials, such as sodium chlorate or sodium nitrate;
c) Chemicals capable of undergoing autothermal decomposition, such as organic
peroxides;
d) Reactive metals (such as sodium, potassium, magnesium, titanium and zirconium),
reactive hydrides, or metal amides, some of which may react violently with some gaseous
extinguishants;
e) Environments where significant surface areas exist at temperatures greater than the
breakdown temperature of the extinguishing agent and are heated by means other

Compensation volume
This is the volume of the propellent gas (Nitrogen) inside the cylinder above the extinguishing
agents.
The compensation volume has the following functions:
oProvide energy required to expel the extinguishing agent at the corresponding
extinguishing pressure.
oCompensation of micro leakages (e.g. natural diffusion through plastic and seals
due to permeability).
In case of excessive leakage, the compensation volume will shrink, and the extinguishing effect
will be reduced due to insufficient pressure. To prevent this, regular servicing is essential. In
addition, AIRfire recommends installing pressure gauges with electric contact to monitor the
pressure levels and to sound an alert signal in case of a drop of pressure below a minimum.
3.2 Cylinder valve (code: 0742A0)
This pneumatically actuated cylinder valve is the main component of the system due to its
connection between the Easydetect sensor tube and the cylinder. The valve will open upon a
drop-in pressure inside the sensor tube (burst due to heat rise/ flame) and opens allowing the
discharge of the extinguishing agent.
The valve includes a dry contact that provide electrical signal when the ball valve lever is closed.
That is why they must be connected to the fire alarm panel so to provide an alarm status when
the system is closed for maintenance procedures for example.

If during servicing the ball valve lever (B) is closed, it must be ensured that the valve
will be reopened later; otherwise the suppression system is out of service and not
available in case of a fire. By employing the valve lever position monitoring dry contact
this risk can be avoided. If the valve is closed a signal is emitted.
3.3 Easydetect sensor tube (code: 125101)
Polymeric tubing with thermal detection capabilities. Easydetect sensor tube is made of high-tech
polymers especially developed for the use as a thermal linear detector in automatic fire
suppression systems. Due to thermal material properties and the inner over-pressure the sensor
tube bursts when touched by a flame or subjected to excessive heat increase.
Technical Specifications:
Marking:
The maximum Easydetect sensor tube length from the container outlet to the end of
any single detection tube run shall not exceed 10 m.
Only using AIRfire Easydetect tube and installing as indicated in this document, rapid
and efficient fire detection without the risk of false alarms is guaranteed.

4.1 Goods reception
1. Check all the material is according to delivery documentation. If you have any doubts do
not hesitate to contact with AIRfire.
2. Carefully unpack the cylinder storing it in a safe place without removing the cap until
necessary. Carefully place the components of the system for easy manipulation.
WARNING: The cylinder is under pressure and must always be manipulated with great
care. The ball valve must always remain closed and secured during manipulation and
storage.
4.2 Mounting of the cylinder
The pressurized cylinder must be mounted and fastened securely in a vertical and upright position
for operation.
Specific ARMANfire brackets supplied by AIRfire or its distributors shall be used.
Horizontal mounting is not permissible as in this position the dip tube will only collect and expel a
fraction of the extinguishing agent not guaranteeing extinguishing of the fire.

floor bracket available. This bracket can be fixed to the floor.
4.3 Installation of the Easydetect tube
4.3.1 Position/ routing instructions
The Easydetect tube must be installed as close as possible to the fire hazards within the enclosure,
so that it may react rapidly upon flame detection. However, ensure that the tube is not mounted
too close to heat sources, this would result in accelerated degradation of the tube material
provoking unintended system activation.
Limits for sensor tube installation:
The end of the Easydetect tube not connected to the valve must be terminated with
an end-of-line adapter or plug. Use only AIRfire tube fittings, which are tested and
approved for the intended application.
