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

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
Siemens Building Technologies Fire Products
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

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

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)

HFC 227ea Extinguishing agent
Page 33 November 2006 Building Technologies© Siemens Switzerland Ltd 2006
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

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

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
Page 49 November 2006 Building Technologies© Siemens Switzerland Ltd 2006
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
