DETECTION SYSTEM REQUIREMENTS
SECTION IV —SYSTEM DESIGN
UL EX.3470 ULC CEx747 Page 4-53
4-1-06 REV.3
Once the fire suppression system design has been determined,adetectionsystemdesignmustbecompleted.This section containsguidelinesandlimitationsfordetectionsysteminstallation.
Detector Identification
The two types of detectors are distinguished from each other bytheirlocationinthedetectionsystem.
1.The Terminal Detector (Part No.56838,15375,or 417368)isthelastinaseriesofdetectors,or the only detector used in asingle-detector system.This detector is thus named becauseitisatthepointatwhichthewireropeends,or ‘erminates’
2.A Series Detector (Part No.56837,15373,or 417369)is anydetectorlocatedin-line between the regulated release mechanismandtheterminaldetector.
Detector/Pulley Elbow Quantity
The quantity of detectors used in the system will vary dependingonthestyleofdetectorused.
1.Conduit runs,pulley elbows,and number of detectors per systemmustbewithintheapprovedsystemguidelines.The followingrequirementsmustnotbeexceeded:
Clip on Style 12 18Detector
Hinge Style 5
Detector
Scissors Style 15 20Detector
2.If hinge style detectors are mixed in a system with either clip-on or scissor style,4 series and 1 terminal is the maximumnumberallowed.If clip-on style are mixed with scissor style,the maximum allowed is 11 series and 1 terminal.
NOTICE
When using the “clip-on”style detector,the terminaldetectormayusethe‘hinged”stylemountingbracketwiththe“clip-on”style linkage.This is only allowed with the terminal detector.
No other linkages are allowed to be mixedwithotherbrackets.When using this option,the total number of “clip-on”style detectors (11seriesand1terminal)is still allowed.
3.If hinge style detectors are mixed in a system with either clip-on or scissor style,the maximum length of wire rope must notexceed103ft.(31.4 m)and the maximum number of pulleyelbowsmustnotexceed8.If clip-on style are mixed with scissorstyle,the maximum length of wire rope must not exceed125ft.(3.81 m)and the maximum number of pulley elbowsmustnotexceed18.
4.If the hazard requires more than 15 detectors,up to five 101RemoteReleases(Part No.32381)can be used for systemactuation.Each 101 remote release allows the use of a maximumof15“scissor”style detectors (14 series and 1 terminal)for a total of 75 detectors if needed.
Detector Placement Requirements
EXHAUST DUCTS
Each exhaust duct must have at least one detector installed in theductentrance,located in the airstream of the cooking vapors,or atamaximumof20ft.(6.1 m)into the duct opening.See Figure 98.
NOTICE
When gas appliances are used and the fluegasesfromtheburnerareexhaustedintothe
dLict,the detector must be kept out of the airstreamoftheseexhaustgases.These gasescanbeveryhotandcouldactuatethesystemunnecessarily.
Duct openings that are long and narrow or largeenoughtorequiremultipleductnozzlesmayrequireadditionaldetectors.
ELECTROSTATIC PRECIPITATOR
If an electrostatic precipitator is located at or near the base of theexhaustduct,it is necessary to locate a detector below the precipitator,at the base of the duct,and also locate one in the duct,lust above the precipitator.See Figure 99.
When installing the detector bracket and system conduit,makecertaintheydonotinterferewiththeoperationoftheprecipitator.

There are three types of R-102 Restaurant Fire SuppressionSystems:
1.Single-tank System
2.Double-tank System
3.Multiple-tank System
The type of system required for the particular installation will bedeterminedthroughtheguidelinescoveredinSystemDesign.”Additional equipment which may be required to complete the systemdesignisexplainedinthe“System Components”section.Additional devices covered are:remote manual pull stations,mechanical and electrical gas shut-off valves,electrical switches,and pressure switches.
Single-Tank System
The R-102 single-tank system is available with a stainless steelenclosureandconsistsof:
1.ANSUL AUTOMAN Regulated Release Assembly (ElectricalorMechanical)
2.Nitrogen Cartridge and/or Carbon Dioxide Cartridge
3.ANSULEX Low pH Liquid Fire Suppressant
4.Discharge Nozzles
5.Detection Components
6.Additional Devices (As Required)
The regulated release assembly contains the regulated releasemechanism,agent tank,expellant gas hose for agent tank hookup,and enclosure knockouts to facilitate installing detection systemandadditionalequipment.Refer to “System Components”sectionforindividualcomponentdescriptions.
Double-Tank System
The R-102 double-tank system is available with a stainless steelenclosureandconsistsof:
