Description

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 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.

Operation
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 moke 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.

Application
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 stablished and generating a high heat output.

Unless otherwise specified, devices described in this guide are suitable for indoor use only.

Device Addressing
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.

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.
