XP95 Multisensor Detector For Marine


Brand Information

The XP95 range of analogue addressable fire detectors uses tried and trusted technology to give the best performance, and has unique features that benefit the installer and the end user. It is suitable for medium-to-large applications with simple installation requirements. As it operates using digital communication, XP95 has a high immunity from corruption, and is, therefore, often preferred in a large system where life safety is critical. XP95 products are frequently used in commercial, industrial, financial, government, IT/telecoms and healthcare applications.


The XP95 multisensor detector contains an optical smoke sensor and a thermistor temperature sensor whose outputs are combined to give the final analogue value. The multisensor construction is similar to that of the optical detector but uses a different lid and optical mouldings to accommodate the thermistor temperature sensor. The sectional view (Fig.15) shows the arrangement of the optical chamber and thermistor. The signals from the optical smoke sensing element and the temperature sensor are independent, and represent the smoke level and the air temperature respectively in the vicinity of the detector. The detector’s microcontroller processes the two signals. The temperature signal processing extracts only rate of rise information for combination with the optical signal. The detector will not respond to a slow temperature increase – even if the temperature reaches a high level. A large sudden change in temperature can, however, cause an alarm without the presence of smoke, if sustained for 20 seconds. 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. Note: in-situ testing of the multisensor should be carried out as for smoke 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 – particularly since restrictions on the transportation of ionisation detectors have been introduced. 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.

Maintenance & Service

Detectors should be maintained according to BS 5839-1 or other locally applicable code. Test equipment can be ordered from Apollo for testing smoke and heat detectors. Detectors should not be cleaned in the field except for careful removal of exterior dirt with a damp cloth. For cleaning and recalibration detectors should be returned to Apollo Fire Detectors or to the local distributor.
