Multi zone Technical Specifications

SV22
– a multi zone system

SV22 system – also called a multi-zone system – is a fire protection solution that with the same cylindere battery protects several zones / spaces.

Select SV22 for multi-zone fire protection

In an SV22 system, the number of bottles needed to fireproof the largest zone is dimensioned. This means that if you have e.g. a desire to fireproof 3 zones, where the largest is of 30 cylinders, the next of 20 cylinders and the last of 10 cylinders, then we put together a system of 30 cylinders that can protect one of the 3 zones in case of fire. You cannot protect all 3 zones at once. The advantage of an SV system is that in the mentioned case you save 30 cylinders compared to if you had chosen a Stand Alone solution. It makes this solution more economical.

Turnkey automatic room extinguishing system

Ci IV8-300 Manosw-plug

Discharge valve for use in Inergen fire extinguishing systems.

The valve has built-in pneumatic activation for inter-system activation, back pressure activation and mechanical activation interface.

The discharge outlet is connected internally to the Pneumatic Actuator (PA) via a check valve (the check valve allows pressure from the discharge side to enter the actuator side), this allows for the discharge port to be used as activation port also (back pressure), hence eliminating the need for PA circuitry between valves connected to the same manifold. When more than one manifold is used, the PA system must be connected to at least one IV8 valve on each manifold.

The port for the PA function works as both inlet and outlet, hence the same connection is used on both pilot and slave cylinders, and the pilot cylinders can be placed anywhere in the line of IV8 valves. All equipment connected to the PA connection must be rated at 300/400 bar.

The standard valve is classified as a Type 2 valve, as it has a built-in burst disc which relieves pressure to the open.

Hose Dn10-400 1,5 Ci Disc Elb

The DN10 pressure hose is used for connection between the discharge valve and the manifold, and qualifies as a type 1 connector in accordance with EN12094-8.

The hose is used in the Control Inert system, SV systems and older INERGEN systems.

Ci IS8B Solenoid actuator

The Solenoid actuator is part of the Control Inert (Ci) series and is designed to activate the Ci IV8 valves, either directly or with the use of either Ci PA8 or SV CiV adapter.

The Ci IS8B has superior performance with regards to shock, vibration and reliability, as it utilizes neodymium magnets, hence reducing the number of moving parts to a minimum.

The Ci IS8B is available either as a standard solenoid or as a solenoid with built-in manual activator. It features a built-in End Of Line resistor allowing monitoring of the complete activation circuit. A built-in current limiter reduces the power consumption after it has been activated.

Ci IS8 NFPA switch

The Ci IS8 NFPA switch is for monitoring of the assembly of the Ci IS8B (solenoid actuator) and the Ci IV8 valve.

It is possible to see electrically via the switch if the two units are disassembled or assembled.

The cable from the switch can be connected to a control panel, which indicates if the two units are disassembled.

SV22 zonekit ISO” calibr CiV

A kit containing components for distribution of INERGEN to one zone in the SV22 system.

The zone kit is designed to be controlled by using the SV CiV Start kit

If “-8” is added to the item number a calibrated orifice will be supplied. Non-calibrated orifices are

supplied with an orifice of ø8.7mm.

SV CiV Start kit

Kit containing components for the installation of one SV CiV control valve on a Ci IV8 discharge valve. The SV CiV is always installed with an appropriate Ci actuator (Ci IS8, Ci PA8 or Ci IM8) connected to it.

The SV CiV is used to activate a Ci IV8 discharge valve and the selector valve connected to it, when the actuator (Ci IS8, Ci PA8 or Ci IM8) is activated.

If the Ci IV8 valve is actuated using back pressure (from the manifold) or the built-in PA system (see Ci IV8 datasheet), the SV CiV will not open.

The SV CiV control valve inlet is connected internally to the Ci IV8 valve, therefore it requires no external gas pressure supply.

SV Test port kit

Test port to be fitted between a control valve and a selector valve for testing the opening pressure of the selector valve and the leak tightness of the control line.

The kit features a check valve that is only open when the test equipment is fitted, hence eliminating potential human errors.

SV22 End plug kit

A kit containing components for blinding off openings which must be closed in the SV22 installation.

The end plug (pos. 15) features a built-in burst disc to prevent over pressurisation of the distribution manifold in case of extreme heating applied to the manifold with closed selector valves.

SV22 Pipe pressure switch kit

This kit is used when a signal for pressurization of the pipe system is required.

The adapter is fitted directly into the SV22 outlet between the selector valve and the pipe adapter.

The adapter features 3 outlets and the pressure switch may be placed in any of these to achieve proper positioning. The unused outlets must be blinded off by the supplied blinding plugs.

If “-8” is added to the part number, special requirements regarding resistance and pressure can be delivered. These specifications are to be supplied by the customer.

Cylinder 80L -300 bar

Steel cylinders with Inergen and Ci Hand Wheel Valve for use in Fire Eater Inergen fire suppression systems. We offer the following cylinders:

200 bar in the sizes:

200 and 300 bar in the sizes:

30L
50L
80L
140L

IN-20 ISO Nozzle calibrated

The nozzle is designed to control the flow using a single orifice with dimensions from Ø1mm to Ø36mm.
The nozzle is designed to disperse the flow laterally (360°) and slightly away from the mounting surface (ceiling/wall).
The nozzle orifice must be calculated specifically for each installation.
Each nozzle must be calibrated and marked individually and permanently with the orifice diameter.
An uncalibrated nozzle is delivered with a 3 mm orifice.
A calibrated nozzle can be ordered with a -8 after the item no.
For example 210204-8 is an IN-15 ISO Nozzle Calibrated.
IMT-calculation or info on the needed orifice diameter must follow orders for -8 item nos.

IN-1/2″ Silencer T2

The IN Nozzle silencer is designed as an add-on to Fire Eater Inergen nozzles to protect equipment sensitive to acoustic noise, eg. hard discs and similar equipment.

The improved performance of the FSN (Flow System Nozzle) is achieved by letting the gas pass through the sound absorbing mesh in two stages.

The flow through the nozzle is not affected by the silencer, as Fire Eater’s calculation software IMT (which is UL listed and FM approved) is based on chocked flow across the nozzle. Adding the silencer to the nozzle does not change the choked flow, neither changes the pressure upstream of the nozzle orifice.

All data specification for the silencer is when used with Fire Eater mono-orifice nozzles.

Use of non-authentic Fire Eater nozzles in combination with the silencer is not advisable, unless it has been tested and verified by Fire Eater.
