Page 4: Introduction
MAN2285-9 1 Introduction FastSense 25 incorporates a patented ‘artificial intelligence‘ known as ClassiFire ® , which allows the detector to configure itself to optimum sensitivity, alarm thresholds and minimum nuisance alarms for any environment. ClassiFire intelligence also monitors the detector chamber and dust separator for contamination, continually adjusting the appropriate operating parameters to counteract the negative effects of such contamination. -

Page 18: Chart Recording
MAN2285-9 Detector sensitivity is based on the fast histogram during FastLearn and is thereafter based on the currently active slow histogram. However, although the positions of the alarm flags are based on the slow histogram, sudden changes in smoke density are picked up by the fast histogram so that early warning is given. Sensitivity: The current absolute sensitivity of the detector in percentage obscuration per metre (% obs/m) Mean: The current mean value of smoke density, taken from the currently “active”... - Page 19 MAN2285-9 chart recording to be loaded.

Page 21: Sampling Pipe Design
MAN2285-9 6 Sampling Pipe Design Above ceiling sampling with exposed detector Simple designs with short sampling pipes produce the best results. Complex sampling pipe runs should be avoided with the FastSense 25 detector. The use of ‘T’ branch-pipes is not recommended. Always locate the sampling points in positions to which smoke may reasonably be expected to travel. -
Page 22: Pipework
MAN2285-9 Above ceiling sampling with detector mounted in ceiling void Sampling Hole Sampling Pipe FastSense 25 False Ceiling Always locate the sampling points in a position to which smoke may reasonably be expected to travel. This may sound obvious, but, for example, do not expect ceiling mounted sampling points to operate satisfactorily if air flow prevents the cool smoke from an incipient fire from reaching ceiling level. -
Page 23: Installation
MAN2285-9 7 Installation Before installing the detector the local standards 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. The detector will normally be mounted at a level where there is easy access to the unit for configuration and programming. -
Page 24: Docking Station
MAN2285-9 7.1 Docking station The basic principle behind installation of the FastSense 25 is that all wiring and pipework is installed using a docking station. This is a convenient feature which means that the detector can be dismounted or replaced without disturbing any wiring or installed pipework. -
Page 25: Mechanical Installation
MAN2285-9 Fitting the pipe adapter 7.1.1 Mechanical installation The docking station is connected to the installed sampling pipework and fixed to the wall or mounting surface using 3 off screws of a type appropriate to the mounting surface.

Page 34: Commissioning
MAN2285-9 10 Commissioning 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. For instance, the test for a computer room (which should be a relatively clean environment) would be very different from, say, a flour mill, which would probably have a high level of airborne particulate content. -
Page 35: Maintenance
MAN2285-9 11 Maintenance FastSense 25 is a very low maintenance detection system. If required, external cleaning of the unit should be performed using a damp (not wet) cloth. Do not use solvents as these may mar the front panel label. The only part that may require field replacement during servicing is the dust separator assembly. - Page 36 MAN2285-9 the system tests. During the “Aspirator and flow” test, the detector fan will suddenly slow down, but this is a normal part of the test and no cause for alarm. If any problems were found during the diagnostic tests, the nature of the fault will be indicated in the “Status” column.

Page 37: Optional Extras
MAN2285-9 12 Optional Extras 12.1 Addressable Protocol Interface Card (APIC’s) General An Addressable Protocol Interface Card (APIC) can be fitted to a FastSense detector to decode detector information and relay it to and from an FACP. That is to say an APIC can be used as a single loop interface unit, or when used with a command module one APIC can be used to communicate data to and from up to 126 FastSense units (via the one APIC module.) If a FastSense unit is fitted to a command module the loop is connected to the BUS connections on the... - Page 38 MAN2285-9 When first ordering APIC cards, it is advisable to check with Ampac that an APIC with the required communication protocol is available before ordering. Address settings There are two address switches on the APIC, SW1 and 2. If only a single loop address is required, both switches are set to the same address, e.g if the sensor address is 4 then both SW1 and SW2 are both set to address 4.
