detectors is advanced in design, improved in performance and has unique features that benefit the installer and the end user. The range includes ionisation and optical smoke detectors, heat detectors as well as a multisensor. All have an unobtrusive profile, a zero insertion force base, user friendly addressing and extended data and alarm features. A manual call point, an isolating base, sounders, beacons and other compatible products are also available. These detectors have been carefully researched and developed by the design team and the range has undergone rigorous testing to ensure that it meets not only European and other standards but also the demands of today’s high technology environments. This Product Guide aims to provide engineers with full information on XP95, in order to be able to design optimum solutions to fire protection problems. 2 Application of XP95 Detectors The choice of detector from the XP95 range follows the well established principles of system design. 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. 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. 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. 3 Addressing and Communications Each XP95 device responds to interrogation and commands from the 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. 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. 2 MAN3037-3 XP95 PRODUCT GUIDE Table 1 - Response characteristics of smoke and heat detectors. 4 Approvals & Regulatory Compliance The XP95 range of detectors and manual call points is approved by a large number of third party certification bodies around the world. These include detector approvals to EN54:2000 with LPCB, VdS, DIBT, BOSEC, AS1603 with Activfire, AS7240 with SAI Global and to UL268 and 521 with UL. XP95 detectors comply with the requirements of a number of European New Approach Directives, such as the EMC Directive 89/336/EEC and the Construction Products Directive 89/106/EEC. All XP95 products will comply with the marking requirements of the WEEE Directive, 2002/96/EC. Australian Standards Currently there are two standards in Australia for point type smoke detectors, the older AS1603.2 standard, and AS7240.7 – which has been adopted from the ISO7240.7 standard (this standard is heavily based on the European EN54.7 standard). AS1603.2 requires the nominal sensitivity (S) of the detector to be between 0 and 15 %Obs/m, with the maximum sensitivity being greater than 0.5S or S-2 and a minimum sensitivity being less than 1.5S or S+2. The test method is specified in AS2362.17 – which states the smoke is produced by burning untempered hardboard (masonite) and the spread of the smoke is unassisted. In practise the smoke does not disperse evenly and tends to “clump” together, and therefore it is not uncommon to get a “spread” of obscuration levels. AS7240.7 does NOT require the sensitivity of the detector to be within a set range. The detector is tested with 4 “test fires” (smouldering wood, smouldering cotton, flaming plastics and flaming heptane) – and the detector must go into alarm before the end of test condition. The end of test condition is an obscuration level (obscuration level is different for each “test fire” type). The obscuration threshold of the detector is determined (using an aerosol generated from pharmaceutical grade paraffin oil) to verify the repeatability, directional dependence and reproducibility of the detector meets the requirements of the standard. The test apparatus used to determine the sensitivity uses wind to assist the dispersion of the aerosol. As the composition of the “smoke” between AS1603.2 and AS7240.7 is different and the test apparatus is different – the resulting threshold sensitivities between the two standards differ. Generally the sensitivities measured under AS1603.2 are higher (up to 5%Obs/m) than measured under AS7240.7. A reason for this is that the smoke spread under AS7240.7 is uniform – as it is wind assisted. It should be noted that under AS7240.7 – the performance of the detector is determined by the response to the 4 test fires, NOT the threshold sensitivity level.

Interrupt Warning: Notification that an XP95 manual call point or XP95 Mini Switch Monitor (interrupt) has been operated. Analogue Value Report: Status continually reported. Input Bits Reporting: Field devices advise control equipment of actions they have taken. For smoke and temperature detectors, these confirm compliance with the output command bits. Bit information depends on device type. Automatic Type Identification: The device being interrogated replies with a 5 bit type code, allowing up to 32 device types. Address Confirmation: The 7- bit address (up to 126 devices per loop) of the detector responding is confirmed back to the control unit. XP95 Device Flag: Tells the control equipment that more information is available. Alarm Flag: For accelerated alarm reporting.
