1About this Guide
This guide is aimed at suitably qualified technicians experi-enced in the design and specification of fire detection and alarm systems, who have also received training.
1.1What this Guide Covers
This guide is for use when designing a fire detection system using addressable detectors, or replacing addressable detectors in an existing system.ers to information on detector choice, and detector siting.This guide is an overall guide to the FC460 addressable detectors.This guide only includes information common to all FC460 detectors. There are more specific leaflets available cover-ing particular types of FC460 detector. These specific leaf-lets include ordering information.
1.2What this Guide does not
This guide does not provide installation information. This is because the detectors simply dock to detector bases, and installation details are provided for the bases.Operating modes of the detectors are set using system application and configuration tools, so only a brief overview is provided in this guide.This guide does not provide information where this is cov-ered by local regulations. For example specific detector sit-ing stipulations are expected to be covered by local regula-tions, so they are excluded from the guide (however brief guidelines are provided).
Reference GuidesThere are a number of system level guides available for download from the fireclass.co.uk website. These support the design, installation and use of fire alarm systems.

2Introduction to the Detectors
The detectors are for use in an addressable system which uses the FireClass Digital Protocol, where a number of detectors are placed in key areas around the building.The function of the detector is simply to quantify environ-mental variables and provide the resulting numerical value to the fire alarm control panel.The fire alarm control panel processes the detector values and assesses whether an alarm needs to be issued.Depending on the detector variant, the environmental vari-ables monitored will be either one or a combination of the following:Smoke density.Concentration of Carbon Monoxide (CO).Figure 1 shows a typical detector and highlights some of the features that are discussed later in the document.
The capabilities of detectors are indicated with a suffix to the detector number. So for example the FC460H is a heat only detector, while the FC460P is an optical smoke detec-tor. These suffixes are shown in Table 1.
The FC460 series detectors are compatible with the
Table 2 shows the types of functionality that are present in the various detectors.
?Self Monitoring? refers to the characteristics or design fea-tures of the detector that allow faults to be detected. For the various sensors these are as follows:Fig. 1: Detector Communications1 ?Status Indicator

For the heat (temperature) sensor there is a normal out-put level to be expected, around ?ambient? tempera-For the CO sensor, the integrity of the sensor cell is con-stantly checked. For the optical (smoke) sensors, the optical chamber is periodically stimulated.
The detectors support a self-test feature.For the self test, fire conditions are artificially simulated within the detector. The detecting sensors will then react as if there were an actual fire.
This indicates as follows:Yellow flashing indicates a detector fault. However, this behaviour can be enabled/disabled as per the settings in the panel configuration software.Red flashing indicates normal operation (flashes on detector poll). However, this behaviour can be enabled/disabled as per the settings in the panel configuration software.Red continuous indicates detector in alarm.
The detectors are capable of driving a Remote LED.
2.3.5Functional Base Compatibility
The detectors are compatible with the range of sounder bases.
The detectors support the ability to compensate for the affects of contamination due to dust and dirt. This prevents an increase in the likelihood of false alarms, extending the operational life of the detector. This function applies only to those detectors with a smoke sensor.
The detectors are addressed by using the FC490ST Loop
The detectors comply with the following standards:Construction Products Directive (CPD), fulfilling the requirements of:?EN 54-5:2000 + A1:2002 – Heat Detectors?EN 54-7:2000 + A1:2002 + A2:2006 – Smoke DetectorsCEA 4021 (2003) – MultiSensor DetectorsVdS 2806 (1999) – Fire Gas DetectorsProduct family standard EN 50130-4 in respect of Con-ducted Disturbances, Radiated Immunity, Electrostatic Discharge, Fast Transients and Slow High EnergyEN 61000-6-3 for Emissions

3 Detector Mode SelectionFC460 Series Detectors

3Detector Mode Selection
Your choice of detector will be determined by the demands of the application.Table 3 is for guidelines only and specific situations are likely to require variations on the suggested detector types. Real situations may require detector combinations to cover all likely risks. Tables 3 and 4 are for guidelines only and specific situa-tions are likely to require variations on the suggested detec-tor types. Customer knowledge of relative impact of false alarm vs undetected fires should be considered.In Tables 3 and 4, the Night and Day columns represent low false alarm risk and high false alarm risk. Although this usu-ally follows a day/ night pattern, it may be configured for any time. For example the car deck of a ferry would be con-figured for Day during vehicle loading and Night once all the passengers had left the car deck, thus achieving opti-mum protection for that area.
