ADDRESSING AND COMMUNICATIONS
Each XP95 evice respon s to interrogation an comman
from central control equipment. It communicates to the
panel information on status, comman bits, type, location,
an other information that allows an alarm to be raise
even when the evice is not itself being interrogate .
Message error checking is also provi e . The evices are
compatible with Series 90, Discovery®an XPlorer systems
an control equipment to ai maintenance, extension an
upgra e of existing systems.
A unique, patente XPERT car provi es simple, user
frien ly an accurate i entification of etector location
whereby a co e car , inserte in the base, is rea by
any etector once it is plugge in. All the electronic
components are in the etector but the location information
is hel in the base. The a ress car simplifies an spee s
up installation an commissioning. A ressing errors
uring maintenance an service are eliminate .
The XP95 manual call point continues to use DIL switch
a ressing, but its interrupt feature also provi es automatic
reporting of its location in the interrupt mo e.
The XP95 etectors provi e an alarm facility that automatically
puts an alarm flag on the ata stream an reports its a ress
when the pre-set EN54 threshol s are excee e . The
evices provi e great flexibility in system esign with the
control equipment etermining the characteristics of the
system. A large an growing range of compatible control
equipment is available from many sources - etails are
inclu e in Apollo publication PP1010, which is available
on request.
APPLICATION OF XP95 DETECTORS
The choice of etector from the XP95 range follows the
well establishe principles of system esign. That is, the
optimum etector type will epen on the type of fire risk
an fire loa , an the type of environment in which the
etector is site .
For general use, smoke etectors are recommen e since
these give the highest level of protection. Smoke etectors
from the XP95 range may be ionisation, optical or
multisensor types. It is generally accepte that ionisation
types have a high sensitivity to flaming fires whereas
optical etectors have high sensitivity to smoul ering fires.
As a result of this, ionisation types are wi ely use for
property protection, an optical types for life protection.
These general principles still apply to XP95 etectors
although the availability of a multisensor in the range
offers more choice to the system esigner.
The multisensor is basically an optical smoke etector an
will therefore respon well to the smoke from smoul ering
fires. The etector 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 etector. The multisensor can
therefore be use as an alternative to an ionisation etector
Where the environment is smoky or irty un er normal
con itions, a heat etector may be more appropriate. It
must be recognise , however, that any heat etector will
respon only when the fire is well establishe an
generating a high heat output.
Unless otherwise specifie , evices escribe in this gui e
are suitable for in oor use only.

is that a small electric current
flows between the electro es.
At the junction between the
reference an smoke chambers
is the sensing electro e that is
use to convert variations in
the chamber currents into a
voltage.
When smoke particles enter
the ionisation chamber, ions
become attache to them
with the result that the current
flowing through the ionisation
chamber ecreases. This
effect is greater in the smoke
chamber than in the reference
chamber an the imbalance
causes the sensing electro e
to go more positive.
The voltage on the sensing
electro e is monitore by
the sensor electronics an
is processe to pro uce a
signal that is translate by
the A/D converter in the
communications ASIC rea y
for transmission when the
evice is interrogate .
XP95 IONISATION SMOKE DETECTOR
XP95 Ionisation Smoke Detector Part Number 55000-500
OPERATING
PRINCIPLES
The XP95 ionisation smoke
etector has a moul e
self-extinguishing white
polycarbonate case with
win resistant smoke inlets.
Stainless steel wiper contacts
connect the etector to the
terminals in the mounting
base. Insi e the etector case
is a printe circuit boar that
has the ionisation chamber
mounte on one si e an
the a ress capture, signal
processing an communications
electronics on the other.
The ionisation chamber
system is an inner reference
chamber containe insi e an
Fig.1 Sectional view - XP95 Ionisation Smoke Detector
outer smoke chamber (Fig 1).
The outer smoke chamber
has smoke inlet apertures
that are fitte with an insect
resistant mesh.
The ra ioactive source
hol er an the outer smoke
chamber are the positive
an negative electro es
respectively. An Americium
241 ra ioactive source
mounte within the inner
reference chamber irra iates
the air in both chambers to
pro uce positive an
negative ions. On applying a
voltage across these
electro es an electric fiel is
forme as shown in Fig 2.
The ions are attracte to the
electro e of the opposite
sign, some ions colli e an
recombine, but the net result

ELECTRICAL
DESCRIPTION
The etector is esigne to
be connecte to a two wire
loop circuit carrying both
ata an a 17V to 28V c
supply. The etector is
connecte to the incoming
an outgoing supply via
terminals L1 an L2 in the
mounting base. A remote
LED in icator requiring not
more than 4mA at 5V may
be connecte between +R
an -R terminals. An earth
connection terminal is also
provi e , although this is
not require for the
functioning of the etector.
When the evice is energise
the ASICs regulate the flow
of power an control the ata
processing. The ionisation
chambers are energise an
the ultra low leakage sensor
ASIC provi es a con itione
analogue signal to the
analogue to igital (A/D)
converter within the
communications an
processing ASIC. When
smoke enters the ionisation
chambers through the integral
gauze, the voltage at the
sensing electro e increases to
pro uce an analogue signal.
An A/D conversion of the
signal from the ionisation
chambers is carrie out once
per secon or when either
the etector or prece ing
a ress is being interrogate .
Whenever the evice is
interrogate this ata is sent
to the control equipment.
EN54 threshol alarm levels
are calibrate within the
processing ASIC. If the
evice is not a resse
within 1 secon of its last
polling an the analogue
value is greater than 55 the
alarm flag is initiate an
the evice a ress is a e
to the ata stream every 32
polling cycles from its last
polling for the uration of
the alarm level con ition,
except when the alarming
evice is being interrogate .
This can provi e a location
i entifie alarm from any
evice on the loop in
approximately two secon s.
The etector is calibrate to
give an analogue value of
25±7 counts in clean air. This
value increases with smoke
ensity. A count of 55
correspon s to the EN54 alarm
sensitivity level. See Fig 3.
Counts of 8 or less in icate
fault con itions. Count levels
between 45 counts an 55
counts can be use to provi e
an early warning of fire.
ENVIRONMENTAL
CHARACTERISTICS
XP95 ionisation smoke
etectors are esigne to
operate in a wi e variety of
environments (See Figs 4 to
6). There are only small
effects from temperature,
humi ity, atmospheric
pressure an win . Detectors
are well protecte against
electromagnetic interference
over a wi e frequency range.
The XP95 ionisation etector,
like all ionisation etectors,
has some sensitivity to air
movement (win ). The
extent to which the analogue
value will change epen s
on the win spee an on
the orientation of the
etector relative to the win
irection. Relatively small
changes in win irection
can cause significant changes
in analogue value.

XP95 Optical Smoke Detector Part Number 55000-600
OPERATING
PRINCIPLES
The XP95 optical etector
uses the same outer case as
the ionisation smoke etector
an is istinguishe by the
in icator LED which is clear
in stan by an re in alarm.
Within the case is a printe
circuit boar which on one
si e has the light proof
labyrinth chamber with
integral gauze surroun ing
the optical measuring system
an on the other the a ress
capture, signal processing an
communications electronics.
An infrare light emitting
io e within its collimator is
arrange at an obtuse angle
to the photo- io e. The
photo- io e has an integral
aylight-blocking filter.
The IR LED emits a burst of
collimate light every secon . Fig.7 Top section - XP95 Optical Smoke Detector
In clear air the photo- io e
receives no light irectly
from the IR LED because of
the angular arrangement
an the ual mask. When
smoke enters the chamber
it scatters photons from the
emitter IR LED onto the
photo- io e in an amount
relate to the smoke
characteristics an ensity.
The photo- io e signal is
processe by the optical
ASIC an passe to the A/D
converter on the
communications ASIC rea y
for transmission when the
evice is interrogate .

the smoke level an the air
temperature respectively in
the vicinity of the etector.
The etector’s microcontroller
processes the two signals.
The temperature signal
processing extracts only
rate of rise information for
combination with the optical
signal. The etector will not
respon to a slow temperature
increase - even if the
temperature reaches a high
level. A large su en change
in temperature can, however,
cause an alarm without the
presence of smoke, if
sustaine for 20 secon s.
The processing algorithms in
the multisensor incorporate
rift compensation. The
control panel must not have
a rift compensation
algorithm enable .
The sensitivity of the etector
is consi ere the optimum
for most general applications
since it offers goo response
to both smoul ering an
flaming fires.
Note: in situ testing of
the multisensor shoul be
carrie out as for smoke
etectors.

XP95 20D ISOLATING BASE
OPERATING
PRINCIPLES
The XP95 20D isolating base
senses an isolates short
circuit faults on XP95 loops
an spurs. The base is loop
powere , polarity sensitive
an accepts the XPERT car
to set the associate evice
a ress.
In short circuit con itions
the integral yellow LED is
illuminate . The etector
associate with the base
remains active un er short
circuit con itions. Power
an signals to the affecte
section are restore
automatically when the
fault is cleare .
ELECTRICAL
DESCRIPTION
Un er normal operating
con itions, a low impe ance
is present between the –IN
an –OUT terminals of the
base, so that power an
signals pass to the next
base in the line.
If a short circuit or abnormally
low impe ance occurs, the
fall in voltage is sense an
the base isolates the negative
supply in the irection of
the fault.
In applications where it is not
necessary to use an isolating
base for each etector, up to
twenty evices ( etectors
an XP95 interfaces) may be
installe between isolating
bases, provi e that their
total switch-on surge current
oes not excee 20mA.
Circuits may inclu e spurs,
which shoul be connecte
between the spare –OUT
terminal an the base L2
terminal. Spurs connecte
in this way appear irectly
across the loop on the
output si e of the isolating
base. Short-circuit faults
on the spur therefore short
circuit the loop an vice
versa. The effect of such
short circuits must be taken
into account in the system
esign an 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

XP95 ISOLATOR .LOOP-POWERED BEAM DETECTOR
MINIDISC REMOTE INDICATOR
LOOP-POWERED SOUNDERS .FLAME DETECTOR
XP95 ISOLATOR
Part Number: 55000-720
Base Part Number: 45681-211
‘Stan -alone’ isolators,
which have their own bases,
may be use instea of
isolating bases. The
isolators are wire to a loop
between etectors or other
evices.
XP95 LOOP-POWERED
BEAM DETECTOR
Part Number: 55000-265
The XP95 optical beam
etector has been esigne
to protect large open spaces
such as museums, churches,
warehouses an factories. It
consists of three main parts:
the transmitter, which projects
a beam of infra-re light,
the receiver, which registers
the light an pro uces an
electrical signal, an the
interface, which processes
the signal an generates
alarm or fault signals.
The transmitter an receiver
are esigne to be fitte on
opposite walls approximately
30cm to 60 cm below the
level of the ceiling. They
can protect an area up to
100m long an 15m wi e,
a total of 1500m2.
The interface contains the
electronic circuitry nee e
to control the beam etector
an communicate with the
control panel via the XP95
loop.
The beam etector is loop-
powere an nee s no
separate 24V supply. This
not only eliminates the nee
for a itional equipment, it
also saves both cost an
time in installation.
INTELLIGENT REFLECTIVE
BEAM DETECTOR
Part Numbers:
55000-268 (5-50m)
55000-273 (50-100m)
The intelligent reflective
beam etector is a compact
etector for etecting smoke
in large open areas such as
atria, warehouses, theatres
an churches. It also has a
built-in 20D negative bi-
irectional short circuit
isolator.
The transmitter an receiver
form a single unit mounte
to a wall of the buil ing. A
reflector which returns the
IR beam from the transmitter
to the receiver is mounte
on the opposite wall. In the
event of smoke partially
obscuring the light an
imbalance between the
transmitte an receive
light will occur. On
interrogation by the control
panel the etector will then
transmit an alarm value.
The intelligent reflective
beam etector is an a ition
to the Apollo range an not
a replacement for the XP95
loop-powere beam
etector.
The intelligent reflective
beam etector is supplie in
two versions: one for use at
istances of 5–50m from
etector to reflector an the
other for istances of 50–
100m.
The etector is non-latching
an resets 30 secon s after
an alarm event ceases an
in 3 secon s after the
removal of a fault.
A termination backbox, part
no 29600-241, is available.
This allows easy first fixing of
the cabling an terminations
to the intelligent reflective
beam etector. The
termination backbox can
be surface or flush mounte .
