Releasing Capabilities for the FS-250


Releasing Features

• Releasing capabilities– Sprinkler (pre-action/deluge)– Clean agent – FM-200

• Will require additional module (FS-REL)• The FS-REL has:

– 2 releasing circuits– Each rated at 1.5A (3A total output power)– 4 open collector outputs (200ma per circuit)

• Large numbers for countdown timer• UL listed w/ all FM approved solenoids


Releasing Features

• On board relays now programmable– Alarm– Trouble– Supervisory– Power Fail – Pre-Alarm– Pre-discharge– Discharge

• Same options for open collector outputs

Important points to note

• New model number for releasing: FS-250-REL. Consists of– FS-250-CON2

• FS-MB2 and FS-DB2– FS-REL– FS-NPE(2)– FS-250-ENCL

• FS-RPT (Releasing Power Transformer) must be used – Only 3A are available for NACs– If OC’s are used it takes away from the total power out of the

releasing card– 3A for NACs and 3A for releasing card


FS-250 Releasing Programming Options

• Devices used for releasing must be assigned to a releasing group• Group activation features:

– Any 1– Any 2-10– Any 1 smoke and any 1 thermal– New option on TRI = Thermal

• Additional input usages– Abort– Manual release

Releasing Zone Threshold


Abort Types

• ULI Standard UL Type delay timer– If an input module is programmed for ULI, when it is activated it

will continue to count down until the timer reaches 10 seconds. At that point the timer will stop as long as the abort switch is active. When the abort switch clears the timer will restart at 10 seconds

• IRI Type Delay Timer– Functions identical to the ULI timer with the exception that the

Abort timer will only function if it is activated and held before the second activation of a cross zone


Abort Types

• NYC type delay timer– If a module is programmed for NYC, when it is activated it will

change to the timer value plus 90 seconds. The timer will not start as long as the abort switch is held

• AHJ Local Jurisdiction delay timer – Once the timer is started activating this module will restore the

timer to its full time. The timer will not start as long as abort is held. Releasing the abort switch will start the timer. Re-activating it will restore it to its full time

Gas extinguishing systems are specified to extinguish a fire at an early stage to avoid damage or shut down costs!

→ early activation of the gas extinguishing system is a must !

Advanced fire protection

Professional active fire protection calls for professional passive and organisational fire protection.

Passive fire protection• realisation of sealed fire compartments• minimisation of fire loads• reduction of protected area sizes and concentration of risks• autonomous ventilation and air conditioning systems and use of fire

dampers• elimination of overpressure if created during discharge

Organisational fire protection• limitation of access to critical risk areas• internal and external alarm organisation

Basic fire protection objectives - Segmentation


Determining the right extinguishing concept

Extinguishing concept mainly depends on:

• risk situation given by the hazard scenario and the fire load(personal safety / availability of fire brigades / etc.)

• customers protection objective(why does the customer want to have a fire protection system)

• national regulations(usually do not meet all customer demands but assure basic protection)

• fire class

Fire classes

Cooling effectEvaporation of water absorbs

considerable heat from the fire.

The smaller the water drops,

the faster the cooling effect.

Suffocating effectIf the oxygen in the air drops

below 2/3 of the normal

content, the fire is suffocated.

Chemical / Physical effectDestruction of the HFC 227 /Novec 1230 / Powdermolecules reduce the

oxygen in the flame.(temperature reduction)

Sinorix™ 227 Extinguishing System


HFC 227ea, heptafluoropropane (C3F7H) halonfluorocarbons (HFCs)

HFC 227ea Extinguishing agent


Fire extinguishing principles with HFC227

Two basic cooling effects:

1. Direct cooling of the flame→ reduction of heat by heat absorption

2. Indirect cooling effect→ reduction of oxygen transfer to the flame

For each extinguishing concept both cooling effects are present;one is always dominating and the other is supportive.

→ This applies for all extinguishing agents!

Sinorix™ High pressure technology:

→average extinguishing time with high pressure: 15 s after end ofdischarge

• reduced damage to highly valued equipment

• less risk of expensive shut down costs due to operational loss.

• no risk of critical concentrations of by-products after fire extinguishing

• Provide fast and total evaporation of the extinguishing agent already during discharge which leads to a perfect homogenisation in

the extinguishing sector

total flooding and object protection - single and multi sector installations- closed objects only if minimum holding time of 10 minutes is

guaranteed

modular & pre-engineered systems- no need of hydraulic calculation software- cylinders are located inside protected area or close by

engineered systems- use of VdS calculation software- cylinders are stored in one central battery within a limited distance

to the protected area

Application of Sinorix™ Hardware


HFC 227ea has been used as a pharmaceutical since 1942propellant for anti-asthmatic sprays

no toxic effect if released into protected areaHFC 227ea is a pharmaceutical product

no critical concentrations of by-products after fire extinguishing if used correctly

chemically inert and clean- no remaining residues after discharge due to complete

evaporation- no interactions with installed equipment

Toxicology of the HFC 227ea


best usable for most fire classes class A (solids)class B (flammable liquids) and C (flammable gases)

fires with some limitationsvery fast extinguishing

discharge time < 10sextinguishing time ~ 10s - 15s after end of

dischargeelectronically non conductive

excellent use to protect electronic riskslow temperature reduction during discharge

Approvals of HFC227ea System


HFC 227ea Extinguishing agent

Halonfluorocarbons are world-wide used and accepted as substitutes to Halon 1301 for industrial and fire protection applications.

• HFC 227ea is not destroying the stratospheric ozone layer (ODP = 0)

• global warming potential of HFC 227ea does not contribute to thetotal emission basket following Kyoto protocol (GWP ~ 2900)

• no toxic effect if released into protected area

• no critical concentrations of by-products after fire extinguishing if used correctly / chemically inert and clean

• no pending ban of the product despite a rumour placed on some markets


Possible dangers of HFC 227ea

Concentration to low→ forming of HF and danger for persons and installations

Concentration to high→ exceed of NOAEL / LOAEL level NOAEL: 9.0 Vol-%

LOAEL: 10.5 Vol-%

Proper design is necessary!After installation no changes in the room can be accepted.


Design concentration for HFC 227ea Agent

Corporate policyAs a minimum requirement, we follow ISO & CEN 14520.

HFC 227ea (including safety factor)

• class A fires: 7,9 Vol% FM200

• class B fires: 9 Vol% FM200 (n-heptane)

• electronic risks: 8.5 Vol% FM200

Higher risks than class B may not be protected by HFC 227ea.

Extinguishing Effect with Novec 1230 Agent

Extinguishing Phenomenasimilar to FM200the large Novec 1230 agent molecule is split in 18 smaller fractions (molecules)

due to thermal effects close to the fire leading to a volumetricexpansion and limitation of the oxygen transport to the fire: the fire is going to be extinguished


Environmental effect of Novec1230

Outstanding Environmental Parameters Close to a Natural Gas

GWP – Value = 1no global warming potential

ALT – Value = 5 to 7 daysminimum atmospheric stability

ODP – Value = 0no negative impact on stratospheric ozone layer

chemical structure: no HFC (Halonfluorocarbon)not affected by any laws and restrictions based upon Kyoto Protocolsuch restrictions are already in the market and or some markets under preparation


Application of Novec1230 System

Excellent System Solution in Addition to Natural Gases for Environmental Sensitive Markets with Restrictions on HFC`s→ customer is demanding for environmental friendly gas

strong limitation on the available cylinder storage spacerelease of overpressure is not possible

e.g. nuclear power plants or room far below ground floormodular system is demandedinstallation of natural gas pipe system during Halon replacement

is very cost intensive
