Chapter 2: Installation and assembly cool smoke from an incipient fire from reaching ceiling level. In this instance it is usually better to locate the sampling pipes directly in the airflow (for example in an air conditioning unit air intake). There is no substitute for carrying out smoke tests prior to installation of pipes to indicate suitable sampling point location.
Chapter 2: Installation and assembly In order for the installation to conform to EN 54-20, pipes must conform at least to EN 61386-1 Class 1131. Sampling pipes must have capped ends. The end cap should be drilled with a sampling hole normally between 4 or 5 mm (0.16 or 0.20 in.) diameter and free from burrs.

Demonstration mode In normal use, the detector remains in a reduced sensitivity mode for 24 hours while it gathers information about its environment.
Chapter 2: Installation and assembly Interfacing with fire alarm panels Because of the flexible nature of the detector and the many possible configurations, there are many options for interfacing the detectors to the fire panel. These include many third party interfaces available from various manufacturers.
Page 39
Chapter 2: Installation and assembly Connecting a detector network to a command module The total length of interconnecting cable between adjacent detectors in the loop should not exceed 1.2 km (3/4 mile). Use a 120 ohm screened twisted pair such as Belden 9841 24 AWG for all loop connections.

Chapter 3: Programming the unit The event log can also be viewed in the Log menu , which prints out the event log in reverse order, i.e., the last recorded event is printed out first. When the buffer that stores events is full (200 events are stored) and a new event occurs, the oldest event in the buffer is discarded.
Chapter 4: Commissioning Introduction This chapter covers the commissioning procedures for the detector. Before commissioning the detector the local standards of aspirating detection systems must be consulted. These standards differ widely 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 7. When the detector is still in FastLearn mode, exit the programming mode on the display by pressing <RESET> and set the detector into Demonstration Mode (see “Detector programmable functions” on page 46 for details). To do this, press and hold down the <RESET>...
Chapter 4: Commissioning Transport time verification The 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 checksheet.

As the detector “learns” the flow setup from the initial installation, this usually means that there has been some change in conditions.

Chapter 6: Maintenance Introduction This chapter contains maintenance instructions for the detection system. These procedures should be performed on a scheduled basis. In the event that system problems are found during routine maintenance, refer to Chapter 5 “Troubleshooting” on page 67. Scheduled maintenance The scheduled maintenance of the system should be performed at an established interval.
Page 75
Chapter 6: Maintenance Maintenance procedures The following paragraphs outline general scheduled maintenance procedures to be performed on an “as necessary” basis. Caution: Risk of equipment damage. Always turn the power off before servicing the detector. Visual check The visual check must be performed every six months. This check is to ensure pipe network integrity.
Page 76
Chapter 6: Maintenance Detector sensitivity test The detector sensitivity test must be performed within one year of installation and every alternate year thereafter. Example: • Year-one check • Year-three check • If years one and three are OK, go to five-year interval. The detector employs a self-monitoring, automatically-adjusting calibration for the system.
