XP95 PRODUCT GUIDE
1
Introduction
The XP95 range of intelligent fire 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.

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.

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.
