Page 8: Positioning Of The Detector
Installation 2.3 Positioning of the detector If the pipes are to be installed in rooms with different pressures, the detector should be located in the room with the lowest pressure. In a building where the ventilation system causes a substantial negative pressure, the detector should be located in the room in which the pipe system is installed. -
Page 9: Cable Entry
Installation 2.5 Cable entry The power supply and loop cables are fed in through the underside of the unit via threaded glands (2 such glands are provided). Threaded glands The unit is also supplied with 2 lead-in holes fitted with plugs. These can be removed as required. -

3.2 Guidelines for agricultural installations For guidelines for agricultural installations, reference is made to the insurance companies’ regulations for fire alarm systems. AutroSense 75 includes among the following: • maximum single pipe length is 46 m •... -
Page 15: Installing The Pipe System In The Roof/Ceiling
Installing the pipe system 3.3 Installing the pipe system in the roof/ceiling To cover a fire zone in a room, the exhaust/suction pipes should be located either directly under the ceiling panels or with a maximum distance of 100 mm to the panels, and laid out in one, two, three or four runs to cover the whole zone area. -
Page 16: Concealed Pipes
Concealed pipes should be secured to ceiling girders or support girders with standard pipe clamps or self-locking clips of nylon. 3.7 Connecting to the AutroSense 75 detector unit The 2 inlets on the top of the detector unit are designed for receiving 25 mm diameter pipes. -
Page 17: Commissioning The System
3. Check that the cables are free from external voltage. 4. If the AutroSense 75 detector unit is connected to a analogue addressable fire alarm system: - check that the interface board and detector is coded to the correct address 5. -
Page 18: Setting Addresses - Analogue Addressable System
Commissioning the system Setting addresses - analogue addressable system • Unscrew the detector cover. The detectors are equipped with 7 address switches marked with the following digital values: 1, 2, 4, 8, 16, 32 and 64. The correct address is found by summing the values of the switches that stand in the OPEN position. -
Page 19: Power Supply
Commissioning the system 4.5 Power supply When all pre-commissioning checks have been completed and the addresses (analogue addressable system only) and switches for air- flow monitoring have been set, then the unit can be connected to the power. • Connect up the 24V DC supply (taken from the external 24V DC outlet on the control panel). -

Commissioning the system 4.7 Final installation tasks • Replace the top cover. IMPORTANT: Ensure that the top cover is replaced correctly to avoid “false” air entering the detector. • Tighten up the 6 screws. Installation & Commissioning Handbook, , P-ASENSE75/IE 980302, 7483 Trondheim Page 19... -
Page 22: Final Testing
Final testing 5. Final testing 5.1 Alarm test / testing of smoke transport time and symmetry • Introduce a puff of smoke (or use an environmentally friendly test gas) into each pipe. • Note the time it takes to give alarm (= smoke transport time). The time lapse should not exceed 120* seconds. -
Page 23: Fire Simulation Test
Final testing 5.3 Fire simulation test To ensure that the aspirating detector functions properly, and to check the integrity of the pipe system, a fire simulation test should be implemented. This test should be as realistic as possible, and the fire should involve the same type of material that can be expected to be found in the monitored fire zones. -
