MANUAL : DOM 00/07 (ii) Issued: July, 2000 Revision No.: MANUAL is intended for use with Pyrogen Industrial Fire Suppression Systems. Thesystems are designed as fixed systems for unoccupied and normally unoccupied systems for total flooding applications shall comply with the requirements of thefollowing Standards:- AS/NZS 4487:1997 Australia/New Zealand Standard Pyrogen Fire Extinguishing Systems; and- AS/NZS :1997 Australia/New Zealand Standard MAINTENANCE of Fire Protection Equipment Part 16: Pyrogen Fire Extinguishing Aerosol SystemsFor the protection of a specified risk area a specific advice and approval may berequired from an appropriate Approval who design, operate, own and maintain these systems should read the entireManual.

3 Specific sections would be of particular interest depending on one sresponsibility. If there should be any questions regarding this MANUAL , please contactour representatives from a Pyrogen office below or contact the nearest PyrogenAuthorised required persons who install and commission Pyrogen systems must beapproved by the Appropriate Authorities. System Design Approval Certificates must becompleted and sent to a Pyrogen office for endorsement prior to supply and installationof a Pyrogen Fire Suppression companies may also be required to supply details to the Approval Authorityprior to each installation and provide a Commissioning Certificate upon completion ofthe installation in the specified risk Pyrogen Fire Suppression System requires minimal MAINTENANCE , mainlysupervision of electrical circuitry, however the system should be inspected at regularintervals to provide maximum assurance that your fire suppression system will operateeffectively and safely.

8 : 1. TerminologyThe following definitions apply to this document:Actuating mechanism: automatic or MANUAL activation leading to the physical dischargeof the : an extinguishant consisting of finely divided solid particles and gaseous matter,these being combustion products of solid aerosol-forming generator: same as Pyrogen generatorAggressive environment: where environmental variables such as temperature and/orvibration undergo cycling at or close to the extreme limits of the Pyrogen atmosphere may also be a authority: a Minister of the Crown, a government department, or other publicauthority having power to issue regulations, order or other instructions having the forceof law in respect of any subject covered by an Industry Standard or, in the case wherenone of these apply, the owner or the owner's and approval: approved by, or the approval of, the appropriate : performing a function without the necessity of human Switch: a device that can be operated before a person enters aspace protected by Pyrogen fire suppression system to prevent automatic release of fireextinguishing aerosol.

9 Normal detection sequence is A fires: fire involving solid materials, usually of organic nature. Can be furthercategorised into surface burning fires and deep-seated fires. Deep-seated firessmoulder and may combust slowly beneath the surface of the B fires: fires involving liquids or liquefiable C fires: fires involving E fires: electrically energised F fires: fats and cooking reaction: a reaction resulting from the activation of a solid aerosol-formingcomposition, which produces fire extinguishing MANUAL : DOM 00/07 1-2 Issued: July, 2000 Revision No.: device: a device to control the sequence of events leading to the release of element: a heat absorbing concentration (g/m3): the mass of Pyrogen aerosol per m3 of enclosure volumerequired to extinguish a specific type of fire, including a safety Factor (g/m3): the mass of Pyrogen solid aerosol-forming composition per m3 ofenclosure volume required to achieve the design quantity: the mass of Pyrogen solid aerosol-forming composition necessary toextinguish a fire in a particular risk, including a safety : aerosol produced from Pyrogen : same as Pyrogen time: the period during which the extinguishant is required to maintain aminimum effective Work.

10 Grinding, welding, thermal or oxygen cutting or heating and other relatedheat-producing or spark-producing : the prevention of ignition of a flammable or explosive atmosphere byestablishing a suitable concentration of drawing: a plan of the risk clearly indicating the as-installed location of allPyrogen generators, controls and MAINTENANCE isolate : requiring human intervention to accomplish a : the supervision of the operating integrity of an electrical control feature of occupied area: an area where, under normal circumstances, humans unoccupied area: an area that is not occupied by humans under normalcircumstances but may be entered occasionally for brief device: any component involved between actuation and release: release of extinguishant initiated by detection system or manualoperation under normal MANUAL : DOM 00/07 1-3 Issued: July, 2000 Revision No.
