Chapter 3: Installation Introduction This chapter provides information necessary to install the EX detector system. Installation consists of the following steps: 1. Determine the optimum location for the detector. 2. Mount the detector in the selected location. 3. Connect the detector to the sampling pipe network. Installation should only be done by factory-trained technicians in accordance with applicable installation requirements, standards, and codes.
Chapter 3: Installation Design Design limitations The EX detector is intended to provide incipient fire detection. It is suitable for the range of applications typified by noncompartmentalised rooms, or items of electronic or electromechanical equipment where it is desirable to achieve incipient fire reporting.
Page 26
Chapter 3: Installation There is no substitute for carrying out smoke tests prior to installation of pipework to indicate suitable sampling point location. Remember that cool smoke from an incipient fire does not behave in the same manner as hot smoke.

Chapter 3: Installation Installation Before installing the detector, the local standards for hazardous areas and for installation of aspirating detection systems must be consulted, as these standards differ throughout the world. Specific advice for one country may not be applicable to another. The following is a brief set of guidelines on installing detectors.
Chapter 3: Installation • Pipework should be metal and bonded to earth/ground to eliminate static electricity buildup. Selection of pipe is left to the site engineers, but the internal diameter should be between 20 and 25 mm. • The exhaust air from the unit must not be impeded in any way. If the unit is mounted in a different air pressure from where the air is being sampled (for example an air duct), then a pipe must be taken from the exhaust port back to the same air pressure zone as the sampling holes.

Chapter 3: Installation Mechanical installation The enclosure is connected to the installed sampling pipework and fixed to the wall or mounting surface using four bolts of a type appropriate to the mounting surface. It is essential that the sampling and exhaust pipes are properly screwed into the flame arrestors.
Page 32
Chapter 3: Installation Figure 10: Removing the display 4. Fit the cable glands, and then route the cables carefully up the sides of the detector assembly as shown in Figure 11 below. 5. Cut the cables to a suitable length. This should be the shortest possible length that will comfortably allow the plugs to fit their respective sockets.
Page 33
Chapter 3: Installation Power supply connections The power supply cable should be of three-core screened type and should be led through cable gland 1 or 2, leaving about 170 mm of the cable extending from cable gland 1 or 100 mm from cable gland 2. Note the orientation of the terminal block.

Chapter 3: Installation Figure 13: Signal connections (1) RS-485 (SenseNET terminals) (2) APIC address terminal (not currently supported) Final installation Slot the power and signal terminal blocks into the relevant sockets on the detector PCB (they will only click fully home in the correct orientation), replace the front display using the four M3 pan-head screws provided and replace the enclosure lid.
Chapter 3: Installation Figure 14: Final installation Interfacing Setting the device address In order to identify itself to a PC or Command Module, each detector on a SenseNET network needs to have a unique address ranging from 1 to 127. The detector address is simply set on the red DIP switch SW1 at the top right of the opened detector on the main circuit board.
Page 36
Chapter 3: Installation segment 1 through 7. (Segment 8 is not used.) An example is shown in Figure 15 below. The address equates to 00100011 in binary, or (1 x 1) + (1 x 2) + (0 x 4) + (0 x 8) + (0 x 16) + (1 x 32) + (0 x 64) = 35.
Chapter 3: Installation Connecting an EX detector to a SenseNET/RS-485 detector network Up to 127 detectors may be linked in a single SenseNET bus, supporting a total length of cable of up to 1.2 km. This can be extended with the use of RS-485 repeaters.
Chapter 3: Installation It may be easier to join the input and output wires for each bus and screen Note: connections together and to solder or crimp a single wire or connecting ferrule to each wire pair so that they are easier to fit into the screw terminals. If this is done, it is recommended that bare wire joints be insulated to prevent possible shorting of the data bus, which will cause a dropout of data on the SenseNET bus.
Chapter 3: Installation connected via an RS-232 serial cable. Complete instructions on how to install, launch and use the the Remote Configuration Software are provided in the Remote Configuration Software User Manual under separate cover. SenseNET The SenseNET software is available for purchase. SenseNET software can configure and manage a large network of detectors with a simple, streamlined graphical user interface from a computer connected to a detector or command module via an RS-232 serial cable or RS-485 converter interface.

Chapter 4: Commissioning Commissioning Before commissioning the detector, the local standards of aspirating detection systems must be consulted. These standards differ throughout the world, and specific advice for the market in one country may not be applicable to another. Commissioning strategy will initially depend upon the environment in which the detector is installed.

Chapter 4: Commissioning Suction pressure verification All sample hole suction pressures should be measured and recorded on the checklist. Measured suction pressures less than 0.5 inches of water are not acceptable. Use the following method to measure sampling point suction pressures (as illustrated in Figure 19).
Chapter 4: Commissioning Transport time verification Maximum transport time verification test is the measure of the amount of time it takes for the detector to respond to smoke that enters the pipe at the sampling point furthest from the detector. The results of this test and the calculated maximum transport time from PipeCAD must be recorded on the checklist.
Chapter 4: Commissioning Wire burner test The wire burner test is considered the most representative test of incipient fire hazard detection in telecommunications or computer room environments. The test is performed by applying a voltage to a piece of PVC-insulated cable. Smoke is produced from the overheated PVC insulation by evaporation and condensation of the plasticizer.
