1 Interactive Fire Alarm System ID: AutroSafe_intro_eng,

2 Milestones in the development of Fire Alarm System by : 1959: The first fully transistorised Conventional Fire Alarm System in the world (BS-10) 1969: The first low voltage smoke detector (BJ-1) 1979: introduces the first Analogue Addressable Fire Alarm System (BS-3) 1989: launches the first Analogue Addressable Fire Alarm System with active handling of detector signals (DYFI) 1999: delivers the first self-verifying Fire Alarm System capable of controlling itself, interactive AutroSafe SelfVerify 2

Operator s Panel Connected to AUTROLON Operates/controls the whole Fire Alarm System, or parts of it All panels have 16x40 character information displays Repeater panel Connected to AUTROLON Controls part of the Fire Alarm System Information Panel Connected to AUTROLON System information only Loop Controller Connected to AUTROLON Controls detector loops and I/O-functions 8

9 Complete range of products for any application Series Units Heat detectors Optical smoke detectors High sensitive smoke detectors Multisensor smoke detectors Manual call points Interface/ address units Sounder Series 200 Standard Interactive Addressable units Series 300 With SelfVerify functions Series 500 With special protection for marine-, offshore-, exi-applications 9

10 SelfVerify, why? Statistics from Offshore: 40% of all critical faults are faults on detectorchamber or electronics. Depending of system type, some or none of these failures are not detected. 45% of all critical faults are functions left disconnected after manual testing. 5% are detectors painted over and hence do not function. Life Cycle Cost: Depending on system type, test periods, etc: Savings 30 70% Same type of faults are expected on landbased systems, savings in Life Cycle Costs are however not supposed to be the same. Better service should mean savings. 10

11 Onshore security Why Self Verification onshore Same failure rates expected Inhibit problem, due to testing Higher system reliability. Simpler and more reliable maintenance Onshore cost. Not the same figures, but still possible to reduce cost on service 11
