That is, the optimum detector type will depend on the type of fire risk and fire load, and the type of environment in which the detector is sited. Each XP95 device responds to interrogation and command from central control equipment. It communicates to the panel information on status, command bits, type, location, and other information that allows an alarm to be raised even when the device is not itself being interrogated. Message error checking is also provided. The devices are compatible with Series 90, Discovery ® and XPlorer systems and control equipment to aid maintenance, extension and upgrade of existing systems. For general use, smoke detectors are recommended since these give the highest level of protection. Smoke detectors from the XP95 range may be ionisation, optical or multisensor types. It is generally accepted that ionisation types have a high sensitivity to flaming fires whereas optical detectors have high sensitivity to smouldering fires. As a result of this, ionisation types are widely used for property protection, and optical types for life protection. These general principles still apply to XP95 detectors although the availability of a multisensor in the range offers more choice to the system designer. page 4 The multisensor is basically an optical smoke detector and will therefore respond well to the smoke from smouldering fires. The detector also senses air temperature. This temperature sensitivity allows the multisensor to give a response to fast burning (flaming) fires, which is similar to that of an ionisation detector. The multisensor can therefore be used as an alternative to an ionisation detector Where the environment is smoky or dirty under normal conditions, a heat detector may be more appropriate. It must be recognised, however, that any heat detector will respond only when the fire is well established and generating a high heat output. Unless otherwise specified, devices described in this guide are suitable for indoor use only. A unique, patented XPERT card provides simple, user friendly and accurate identification of detector location whereby a coded card, inserted in the base, is read by any detector once it is plugged in. All the electronic components are in the detector but the location information is held in the base. The address card simplifies and speeds up installation and commissioning. Addressing errors during maintenance and service are eliminated. The XP95 manual call point continues to use DIL switch addressing, but its interrupt feature also provides automatic reporting of its location in the interrupt mode. The XP95 detectors provide an alarm facility that automatically puts an alarm flag on the data stream and reports its address when the pre-set EN54 thresholds are exceeded. The devices provide great flexibility in system design with the control equipment determining the characteristics of the system. A large and growing range of compatible control equipment is available from many sources - details are included in Apollo publication PP1010, which is available on request.

Stainless steel wiper contacts connect the detector to the terminals in the mounting base. Inside the detector case is a printed circuit board that has the ionisation chamber mounted on one side and the address capture, signal processing and communications electronics on the other. The ionisation chamber system is an inner reference chamber contained inside an Part Number 55000-500 outer smoke chamber (Fig 1). The outer smoke chamber has smoke inlet apertures that are fitted with an insect resistant mesh. The radioactive source holder and the outer smoke chamber are the positive and negative electrodes respectively. An Americium 241 radioactive source mounted within the inner reference chamber irradiates the air in both chambers to produce positive and negative ions. On applying a voltage across these electrodes an electric field is formed as shown in Fig 2. The ions are attracted to the electrode of the opposite sign, some ions collide and recombine, but the net result Sectional view - XP95 Ionisation Smoke Detector is that a small electric current flows between the electrodes. At the junction between the reference and smoke chambers is the sensing electrode that is used to convert variations in the chamber currents into a voltage. When smoke particles enter the ionisation chamber, ions become attached to them with the result that the current flowing through the ionisation chamber decreases. This effect is greater in the smoke chamber than in the reference chamber and the imbalance causes the sensing electrode to go more positive. The voltage on the sensing electrode is monitored by the sensor electronics and is processed to produce a signal that is translated by the A/D converter in the communications ASIC ready for transmission when the device is interrogated. Fig.2 Diagram showing lines of equipotential for the XP95 Ionisation Smoke Monitor ELECTRICAL DESCRIPTION The detector is designed to be connected to a two wire loop circuit carrying both data and a 17V to 28V dc supply. The detector is connected to the incoming and outgoing supply via terminals L1 and L2 in the mounting base. A remote LED indicator requiring not more than 4mA at 5V may be connected between +R and -R terminals. An earth connection terminal is also provided, although this is not required for the functioning of the detector. When the device is energised the ASICs regulate the flow of power and control the data processing. The ionisation chambers are energised and the ultra low leakage sensor ASIC provides a conditioned analogue signal to the analogue to digital (A/D) converter within the communications and processing ASIC. When smoke enters the ionisation chambers through the integral gauze, the voltage at the sensing electrode increases to produce an analogue signal. An A/D conversion of the signal from the ionisation chambers is carried out once per second or when either the detector or preceding address is being interrogated. Whenever the device is interrogated this data is sent to the control equipment. EN54 threshold alarm levels are calibrated within the processing ASIC. If the device is not addressed within 1 second of its last polling and the analogue value is greater than 55 the alarm flag is initiated and the device address is added to the data stream every 32 polling cycles from its last polling for the duration of the alarm level condition, except when the alarming device is being interrogated. This can provide a location identified alarm from any device on the loop in approximately two seconds. The detector is calibrated to give an analogue value of 25±7 counts in clean air. This value increases with smoke density. A count of 55 corresponds to the EN54 alarm sensitivity level. See Fig 3. Counts of 8 or less indicate fault conditions. Count levels between 45 counts and 55 counts can be used to provide an early warning of fire. Fig.3 Typical response characteristics - XP95 Ionisation Detector Fig.4 Typical temperature response - XP95 Ionisation Detector page 7 ENVIRONMENTAL CHARACTERISTICS XP95 ionisation smoke detectors are designed to operate in a wide variety of environments (See Figs 4 to 6). There are only small effects from temperature, humidity, atmospheric pressure and wind. Detectors are well protected against electromagnetic interference over a wide frequency range. The XP95 ionisation detector, like all ionisation detectors, has some sensitivity to air movement (wind). The extent to which the analogue value will change depends on the wind speed and on the orientation of the detector relative to the wind direction. Relatively small changes in wind direction can cause significant changes in analogue value.

The detectors, independently tested by the National Radiological Protection Board (NRPB), conform to all the requirements specified in the ‘Recommendations for ionisation smoke detectors in implementation of radiation standards’ published by the Nuclear Energy Agency of the Vibration, Impact & Shock: To EN54–7:2000 Electro-magnetic Compatibility: See page 21 for full details IP Rating: 23D Approvals & Regulatory Compliance: See page 21 for full details Dimensions: (diameter x height) Detector: 100mm x 42mm Detector in Base: 100mm x 50mm Weights: Detector: 105g Detector in Base: 161g Materials: Detector Housing: White polycarbonate V-0 rated to UL 94 Terminals: Nickel plated stainless steel Wind Speed: 10m/s maximum technical data For wind speeds up to 1m/s (200ft/min) the change in analogue value will not exceed 5 counts. Continuous operation in wind speeds greater than 2m/s (400ft/min) is not recommended. However, wind speeds up to 10m/s (2000ft/min) can be tolerated for short periods and will not under any conditions increase the probability of false alarms. Atmospheric Pressure: Automatic compensation by dual chambers to maintain sensitivity up to a height of 2000m above sea level Organisation for Economic Co-operation and Development (OECD) 1977. There is no limit to the number of ionisation smoke detectors which may be installed in any fire protection system within the UK. See Certificate of Approval No. TA1 of 1999 issues by the HSE for further details. Storage regulations depend on local standards and the legislation, but, in the UK, the number of ionisation smoke detectors in any building or premises shall be less than 500. See Certificate of Approval No. TA3 of 1999 issued by the HSE for further details. At the end of their recommended working life 0832 of ten years, ionisation smoke detectors should be returned to Apollo for safe disposal or disposed of in an otherwise locally approved and environmentally safe manner.

XP95 OPTICAL SMOKE DETECTOR supply. The detector is connected to the incoming and outgoing supply via terminals L1 and L2 in the mounting base. A remote LED indicator requiring not more than 4mA at 5V may be connected between the +R and -R terminals. An earth connection terminal is also provided. XP95 Optical Smoke Detector Part Number 55000-600 In clear air the photo-diode receives no light directly from the IR LED because of OPERATING the angular arrangement PRINCIPLES and the dual mask.

An infrared light emitting diode within its collimator is arranged at an obtuse angle to the photo-diode. The photo-diode has an integral daylight-blocking filter. The IR LED emits a burst of collimated light every second. When the device is energised the ASICs regulate the flow of power and control the data processing. The optical ASIC is controlled by the communications ASIC and pulses the IR LED. The signal from the photo-diode is processed by the optical ASIC and transferred to the A/D converter in the communications ASIC where it is then stored. When smoke enters the chamber the photo-diode signal increases. The information to the A/D converter is updated once per second or when either the monitor or the preceding address is interrogated. Whenever the device is interrogated this data is sent to the control equipment. EN54 threshold alarm levels are calibrated within the processing ASIC. If the device is not addressed within 1 second of its last polling and the analogue value is greater than the EN54 alarm level the alarm flag is initiated and the device address is added to the data stream every 32 polling cycles from its last polling for the duration of the alarm level condition, except when the alarming device is being interrogated. This can provide a location identified alarm from any device on the loop in approximately 2 seconds. The detector is calibrated to give an analogue value of 25±7 counts in clean air. This value increases with smoke density. A count of 55 corresponds to the EN54 alarm sensitivity level. See Fig.9. ENVIRONMENTAL CHARACTERISTICS The XP95 optical smoke detector is unaffected by wind or atmospheric pressure and operates over the temperature range -20°C to +60°C. See Fig. 10.

OPERATING PRINCIPLES The XP95 heat detectors have a common profile with ionisation and optical smoke detectors but have a low air flow resistance case made of self-extinguishing white polycarbonate. The devices monitor heat by using a single thermistor network which provides a voltage output proportional to the Fig.11 The standard heat detectors, 55000-400 and 55000-420, respond to increasing air temperature in such a way that they are classified as an A2S device. See figure 13. Both devices will give 55 counts at 55°C. A high temperature CS heat detector, 55000-401, which can be installed in a typical ambient temperature of 55°C is available. See figure 14. This device will give 55 counts at 90°C.

The detectors are connected to the incoming and outgoing supply via terminals L1 and L2 in the mounting base. A remote LED indicator requiring not more than 4mA at 5V may be connected between +R and -R terminals. An earth connection terminal is also provided. When a device is energised the ASIC regulates the flow of power and controls the data processing. The thermistor provides an output over normal operating ranges that is proportional to the external air temperature. This voltage output is processed in the A/D converter and stored by the communications ASIC. It is transmitted to control equipment when the device is interrogated. When a count of 55 is exceeded the alarm flag is initiated and the device address is added to the data stream every 32 polling cycles from its last polling for the duration of the alarm level condition, except when an alarming device is being interrogated. This can provide a location identified alarm from any device on the loop in approximately two seconds. The detector is calibrated to give an analogue value of 25±5 counts at 25°C. ENVIRONMENTAL CHARACTERISTICS XP95 Standard Heat Detectors operate over the range -20°C to +70°C, the High Temperature Heat Detectors operate over the range –20°C to +120°C.

The sectional view (Fig.15) shows the arrangement of the optical chamber and thermistor. The processing algorithms in the multisensor incorporate drift compensation. The control panel must not have a drift compensation algorithm enabled. The sensitivity of the detector is considered the optimum for most general applications since it offers good response to both smouldering and flaming fires.

The base is loop powered, polarity sensitive and accepts the XPERT card to set the associated device address. Under normal operating conditions, a low impedance is present between the –IN and –OUT terminals of the base, so that power and signals pass to the next base in the line. In short circuit conditions the integral yellow LED is illuminated. The detector associated with the base remains active under short circuit conditions. Power and signals to the affected section are restored automatically when the fault is cleared. If a short circuit or abnormally low impedance occurs, the fall in voltage is sensed and the base isolates the negative supply in the direction of the fault. In applications where it is not necessary to use an isolating base for each detector, up to twenty devices (detectors and XP95 interfaces) may be installed between isolating bases, provided that their Isolation Indicator: Yellow LED, lit continually in isolation condition Current Consumption: at 18V 23µA at 28V 43µA at 18V and adjacent sector isolated 4mA total switch-on surge current does not exceed 20mA. Circuits may include spurs, which should be connected between the spare –OUT terminal and the base L2 terminal. Spurs connected in this way appear directly across the loop on the output side of the isolating base. Short-circuit faults on the spur therefore short circuit the loop and vice versa. The effect of such short circuits must be taken into account in the system design and may require the use of extra isolating bases. For further information on the use of XP95 isolators, please refer to PP2090 Short Circuit Isolation in XP95 and Discovery Fire Systems.

The isolators are wired to a loop between detectors or other devices. XP95 LOOP-POWERED BEAM DETECTOR Part Number: 55000-265 The XP95 optical beam detector has been designed to protect large open spaces such as museums, churches, warehouses and factories. It consists of three main parts: the transmitter, which projects a beam of infra-red light, the receiver, which registers the light and produces an electrical signal, and the interface, which processes the signal and generates alarm or fault signals. The transmitter and receiver are designed to be fitted on opposite walls approximately 30cm to 60 cm below the level of the ceiling. They can protect an area up to 100m long and 15m wide, a total of 1500m2. The interface contains the electronic circuitry needed to control the beam detector and communicate with the control panel via the XP95 loop. The beam detector is looppowered and needs no separate 24V supply. This not only eliminates the need for additional equipment, it also saves both cost and time in installation. ISOLATOR . LOOP-POWERED BEAM DETECTOR MINIDISC REMOTE INDICATOR LOOP-POWERED SOUNDERS . FLAME DETECTOR INTELLIGENT REFLECTIVE BEAM DETECTOR Part Numbers: 55000-268 (5-50m) 55000-273 (50-100m) The intelligent reflective beam detector is a compact detector for detecting smoke in large open areas such as atria, warehouses, theatres and churches. It also has a built-in 20D negative bidirectional short circuit isolator. The transmitter and receiver form a single unit mounted to a wall of the building. A reflector which returns the IR beam from the transmitter to the receiver is mounted on the opposite wall. In the event of smoke partially obscuring the light an imbalance between the transmitted and received light will occur. On interrogation by the control panel the detector will then transmit an alarm value. The intelligent reflective beam detector is an addition to the Apollo range and not a replacement for the XP95 loop-powered beam detector. The intelligent reflective beam detector is supplied in two versions: one for use at distances of 5–50m from detector to reflector and the other for distances of 50– 100m. The detector is non-latching and resets 30 seconds after an alarm event ceases and in 3 seconds after the removal of a fault. A termination backbox, part no 29600-241, is available. This allows easy first fixing of the cabling and terminations to the intelligent reflective beam detector. The termination backbox can be surface or flush mounted. MINIDISC REMOTE INDICATOR Alarms may be signalled visually by means of a flashing beacon. Combined sounder beacon units are available where both audible and visual signalling is required. The following types of device are available: Part Number: 53832-070 A light-weight, compact indicator for use in fire protection systems. The indicator may be used in all installations incorporating Series 60, XP95, Discovery and Intrinsically Safe detectors. It is only 20mm high and 80mm in diameter. It comprises two parts – the base, which is installed onto a wall or soffit and the lid, which is fitted to the base with a bayonet lock. LOOP-POWERED SOUNDERS, BEACON & SOUNDER BEACONS There are two types of looppowered sounder available, allowing fire engineers to specify not only the sound output but also the functionality of individual sounders. The 85dB(A) Low-Profile loop sounder is intended for use in confined spaces such as hotel rooms and corridors. It is designed to have a base and detector mounted upon it, but can also be used as a stand-alone sounder. The 100dB(A) loop sounder is intended as an open-space sounder, where a higher output is required. Ancillary Base Sounder Part Number: 55000-276 A local-area sounder with an integral base for a detector head. The sounder is switched by the detector remote output and needs no address of its own.
