CONVENTIONAL DETECTORS
When would I use a multisensor?
Multisensor smoke detectors have a heat
sensing element which makes them more
sensitive if a fire develops heat as well as
smoke. This speeds up the response of
the detector in certain fires where heat is
generated rapidly, for instance in test fire
TF5, which is an open, flaming liquid fire
in which n-heptane is burned.
Multisensor smoke detectors are
recommended for open flaming fire risks.
If there is any doubt as to whether an
optical detector or a multisensor smoke
detector should be used it is wise to fit a
multisensor smoke detector.
Where would there be a need to install
heat detectors?
Heat detectors should be used if it is not
possible to use smoke detectors. This
will be the case for example in kitchens
and smoking areas and where normal
industrial processes produce substances
which could be mistaken for smoke by
a smoke detector, eg, flour mills, textile
mills or loading bays with diesel-engined
vehicles.
The type of substance encountered here
would cause frequent false alarms if
smoke detectors were fitted, so a heat
detector is used instead.
Should I use optical detectors to detect
smoke in all applications?
Optical detectors have long been
recommended as good general purpose
smoke detectors. Laboratory tests
have been carried out to compare the
performance of optical detectors in
the standard test fires described in the
European standard EN54.
The results of these tests are given in
Fig 1. The graph shows the acceptable
response in terms of smoke density which
is given as ‘m’ on the y axis. Detectors
must respond before the end of test which
is an ‘m’ = value of 2. The performance
of Orbis detectors is given as a solid line
which shows how evenly the optical
detectors respond to the test fires.
If detectors respond too quickly (the lower
shaded portion of the graph) they may be
too sensitive and hence likely to generate
false alarms.
If detectors respond too slowly (the upper
shaded portion) they are in danger of not
changing to the alarm state before the
end of test.
An even response in the centre is the
ideal response.

How are heat detectors classified?
EN54 classifies heat detectors according
to the ambient temperature in which
they will be working and according to
whether they may be tested as ‘static’
detectors (changing to alarm at a preset
temperature) or ‘rate-of-rise’ (changing to
alarm at a preset increase of temperature).
Heat detectors may also be marketed
without either classification; but then the
detection characteristics are unknown.
All Orbis heat detectors are tested and
classified as either static or rate-of-rise.
So what is the best way to choose a heat
detector?
To make things easier we have produced
a flow chart which is shown on page 10.

WHERE TO USE OPTICAL
SMOKE DETECTORS
Optical smoke detectors have always
been recognised as good detectors
for general use. They are regarded as
particularly suitable for smouldering fires
and escape routes.
The performance of Orbis optical
detectors is good in black as well as in
white smoke. In this respect Orbis is
different from traditional optical smoke
detectors which perform far better in white
smoke than in black.
Orbis optical detectors are also designed
to reduce significantly the incidence of
false alarms through over-sensitivity to
transient phenomena.
Orbis optical detectors are recommended
for use as general purpose smoke detectors
for early warning of fire in most areas.
ORBIS OPTICAL SMOKE
DETECTOR
The sensing technology in the Orbis
optical smoke detector is significantly
different in design from previous optical
detectors. A full description is given in
the section ‘How do orbis optical smoke
detectors work?’ but the advantages of this
system and its associated algorithms are:
•improvedsensitivitytoblacksmoke
•compensationforslowchangesin
sensitivity
•extraconfirmationofsmokebefore
the alarm signal given
The algorithms are used to verify signals
from the sensing chamber, to filter out
transients and to decide when the detector
should change to the alarm state.
All this combines to increase detection
reliability and reduce false alarms.
HOW DOES THE ORBIS
OPTICAL DETECTOR WORK?
Orbis operates on the well established
light scatter principle. The remarkable
optical design of the Orbis optical smoke
detector allows it to respond to a wide
spectrum of fires.
The sensing chamber of the Orbis optical
smoke detector contains an optical sensor
which measures back-scattered light as
well as the more usual forward-scattered
light. Sensitivity to black smoke is greatly
improved.
The detector is calibrated so that Orbis
is highly reliable in detecting fires but is
much less likely to generate false alarms
than earlier smoke detectors.
The stability of the detector–high
reliability, low false alarm rate–is further
increased by the use of algorithms to
decide when the detector should change
to the alarm state. This removes the
likelihood of a detector producing an
alarm as a result of smoke from smoking
materials or from another non-fire source.

WHERE TO USE
MULTISENSOR SMOKE
DETECTORS
Multisensor smoke detectors are
recognised as good detectors for general
use but are additionally more sensitive to
fast burning, flaming fires–including liquid
fires–than optical detectors.
They can be readily used instead of optical
smoke detectors but should be used as
the detector of choice for areas where
the fire risk is likely to include heat at an
early stage in the development of the fire.
As with Orbis optical smoke detectors
the increased reliability of detection is
combined with high immunity to false
alarms.
The multisensor smoke detector has two
sensors, one for smoke, one for heat and
the alarm decision is derived from either
sensor or a combination of both. The
multisensor is a development of the Orbis
optical detector described in the previous
chapter and goes further in its capabilities
of fire detection.
The optical sensor is identical to the
one in the Orbis optical detector. Its
sensitivity is, however, influenced by a
heat sensing element which makes the
detector more responsive to fast-burning,
flaming fires.
ENVIRONMENTAL
PERFORMANCE
The environmental performance of the
multisensor detector is the same as that of
the Orbis optical smoke detector.

HEAT
DETECTOR
Part Number ORB-HT-11001-APO
WHERE TO USE HEAT
DETECTORS
Heat detectors are used in applications
where smoke detectors are unsuitable.
Smoke detectors are used wherever
possible since smoke detection provides
earlier warning of fire than heat detection.
There are, however, limits to the
application of smoke detectors and these
are described in the section ‘features of
Orbis’ on page 4.
Heat detectors should be used if there is
a danger of nuisance alarms from smoke
detectors.
ORBIS HEAT DETECTOR
The Orbis range incorporates seven heat
detector classes to suit a wide variety of
operating conditions in which smoke
detectors are unsuitable.
The European standard EN54-5:2001
classifies heat detectors according to the
highest ambient temperature in which
they can safely be used without risk of
false alarm. The classes are identified by
the letters A to G. (Class A is subdivided
into A1 and A2.) In addition to the basic
classification, detectors may be identified
by a suffix to show that they are rate-of-
rise (suffix R) or fixed temperature (suffix
S) types.
All heat detectors in the Orbis range are
tested as static or rate-of-rise detectors
and are classified as A1R, A1S, A2S, BR,
BS, CR and CS.

CHOOSING THE
CORRECT CLASS OF
HEAT DETECTOR
Heat detectors have a wide range of
response characteristics and the choice of
the right type for a particular application
may not always seem straightforward.
It is helpful to understand the way that
heat detectors are classified as explained
earlier and to memorise a simple rule: use
the most sensitive heat detector available
consistent with avoiding false alarms.
In the case of heat detectors it may be
necessary to take an heuristic approach,
ie, trial and error, until the best solution
for a particular site has been found. The
flowchart (Fig. 3) will assist in choosing
the right class of heat detector.
If the fire detection system is being
designed to comply with BS 5839–1:
2002 heat detectors should be installed
at heights of less than 12 metres with the
exception of class A1 detectors, which can
be installed at heights up to 13.5 metres.
HOW DO ORBIS HEAT
DETECTORS WORK?
Orbis heat detectors have an open-web
casing which allows air to flow freely
across a thermistor which measures
the air temperature every 2 seconds. A
microprocessor stores the temperatures
and compares them with pre-set values to
determine whether a fixed upper limit–the
alarm level–has been reached.
In the case of rate-of-rise detectors
the microprocessor uses algorithms to
determine how fast the temperature is
increasing.
Static heat detectors respond only when
a fixed temperature has been reached.
Rate-of-rise detectors also have a fixed
upper limit but they also measure the rate
of increase in temperature. A fire might
thus be detected at an earlier stage than
with a static detector so that a rate-of-rise
detector is to be preferred to a static heat
detector unless sharp increases of heat are
part of the normal environment in the area
protected by the heat detector.
ENVIRONMENTAL
PERFORMANCE
The environmental performance is similar
to that of the Orbis optical smoke detector
but it should be noted that heat detectors
are designed to work at particular ambient
temperatures (see Fig 3).

TIMESAVER
BASE®
Part Number ORB-MB-00001-APO
INSTALLING ORBIS
Orbis has been designed to make
installation fast and simple. Fig 4 shows
the TimeSaver mounting base as it is seen
from the installer’s point of view.
The E-Z fit fixing holes are shaped to allow
a simple three-step mounting procedure:
•Fittwoscrewstothemountingbox
or surface
•PlacetheOrbisbaseoverthe
screws and slide home
•Tightenthescrews
The base offers two fixing centres at 51
and 60mm.
A guide on the base interior indicates
the length of cable to be stripped. Five
terminals are provided for the cables,
four being grouped together for ease of
termination.
The terminals are:
•positiveIN
•positiveOUT
•negativeINandOUT(common
terminal)
•remoteLEDnegativeconnection
•functionalearth(screen)
The terminal screws are captive screws
and will not fall out of the terminals.
The base is supplied with the screws
unscrewed in order to avoid unnecessary
work for the installer.
The end-of-line resistor or active device
should be connected between the OUT+
and COM– terminals.
If it is required that all detectors be fitted
with their LEDs facing the same direction
the bases must be fitted to the ceiling
observing the marking on the exterior
which indicates the position of the LED.
The bases may be connected as shown in
Fig 5 where remote LEDs, if required, are
connected to the associated base.
Fig 6 shows how to connect one remote
LED to more than one base so that an
alarm in any of the detectors connected
will switch the remote LED.
In many installations bases with diodes
are specified in order that an active end-
of-line device may be fitted. Diode bases
are marked ‘OD’. Loop continuity testing
is facilitated as there is a continuity device
in the base. The continuity device enables
power to pass through every base in a loop
to ensure that each is connected correctly.
Once a detector is fitted to the base the
continuity device is automatically locked
permanently open so that the power flows
through the detectors.
FITTING ORBIS
DETECTOR HEADS
When the bases have been installed and
the system wiring tested, the detector
circuits can be populated.
Two methods are suggested:
1. Apply power and fit the detectors one
by one, starting at the base nearest
the panel and working towards the
end of the circuit. As each detector
is powered up it will enter ‘StartUp’
and flash red (see next page for a
full description of this feature). If the
LED does not flash, check the wiring
polarity on the base and ensure there
is power across IN+ and COM–. If the
LED is flashing yellow the detector
is not operating correctly and may
require maintenance or replacing
(see DirtAlert and SensAlert® below
and the section ‘Maintenance and
servicing’ on page 15).
2. Fit all detectors to the circuit, apply
power and check detectors by
observing the LED status of each
device. The StartUp feature lasts for
4 minutes so it may be necessary to
reset or de-power the circuit to allow
all detectors to be observed. The LED
status is the same as method 1.

The TimeSaver Base® is a design
that provides installers with an open
working area with fixing holes shaped
to allow a fast mounting procedure.
The relay base incorporates a single-
pole voltage-free changeover contact
for switching ancillary equipment. The
maximum contact rating is 30V 1A.
When the detector changes to the
alarm state, the relay is energised,
causing the contact to change state.
The contact will remain in this
condition until the detector is reset.
A base is available which allows Orbis
detectors to be used in ‘Sav-Wire’
detection and alarm systems. Care
should be taken to connect Sav-Wire
bases correctly as shown in fig 9.
The Orbis Heater base is designed
to be used in cold climates where
environmental conditions could
result in either icing or condensation
affecting the operation of detectors. It

CONVENTIONAL DETECTORS
In the case of heat detectors a fast test is
defined as a sample which recognises a
rise of 10°C within one minute. Since
sampling takes place every 2 seconds an
Orbis heat detector will respond within
about 4 seconds.
Smoke or Heat Testing
Smoke or heat testing Orbis detectors is
aided by the FasTest® feature. A detector
will react rapidly to the correct stimulus if
applied within 4 minutes after power up.
Choose the appropriate test function on
the control panel and reset the detector
circuit. This should place the detectors
into FasTest®. Apply smoke or heat as
appropriate and the detector should
enter the alarm state within 4 seconds.
The panel may sound the alarm and reset
the zone automatically (refer to control
panel’s instructions). If not, silence the
alarm and reset the panel. Repeat the
procedure as necessary.
Note that the multisensor detector will
respond to either smoke or heat while
in FasTest®.
MAINTENANCE AND
SERVICING
Detectors should be checked regularly
at the intervals indicated by the locally
applicable code of practice. Apollo
recommends that detectors be checked
at least once a year.
One of the features of Orbis is FasTest®
which makes it possible to carry out
a functional test, using smoke or heat,
within about four seconds. If detectors
appear not to be functioning correctly
they should be returned to Apollo for
testing.
If detectors are externally dirty they
can be cleaned carefully with a damp
cloth using a small amount of industrial
alcohol.
DirtAlert™
Orbis detectors have drift compensation
to compensate for changes caused by the
environment. The most usual change is
contamination.
If the detector is dirty to the point where
it can no longer compensate, its LED
will flash yellow while it is in StartUp.
Maintenance checks should therefore
include removing a detector from its base
and re-inserting it or pressing reset on the
panel to initate StartUp.
COMMMISSIONING
MADE EASY
Orbis has been designed with a number
of features that make commissioning
easier and that save time.
StartUp
When Orbis detectors are powered up
they automatically enter a phase known
as StartUp and in which they stay for 4
minutes. After this they revert to normal
operation. If the detector is reset, ie, if
power is disconnected for one second
or longer, the detector will always enter
StartUp for the first four minutes after
power has been restored. The detector
LED flashes red once a second to indicate
that it is in StartUp.
What StartUp indicates
StartUp is used to check that the positive
and negative cables are connected in the
correct polarity and that power has been
applied to the detector. If this is the case,
the LED will flash red once a second.
StartUp will not check whether the IN+
and OUT+ connections have been
transposed. This is not a problem if
standard bases are used as the detector
will operate normally.
If, however, diode bases are used and
a detector is removed from a base with
transposed positive connections none
of the detectors beyond this point will
operate.
FasTest®
Orbis detectors incorporate a test facility
known as FasTest®.
In normal operation Orbis smoke
detectors do not change to the alarm
state at the first sensing of smoke. If
they did, they could be too sensitive and
cause false alarms. Algorithms determine
the point at which the detector changes
to alarm.
This could slow down routine
maintenance during which detectors are
tested by means of smoke or a smoke-
simulating substance.
In order to avoid such a problem Orbis
detectors have FasTest, a facility which
is automatically available during StartUp
and which modifies algorithms so that
testing is possible within 4 seconds.
The problem of testing is even more
acute in the case of heat detectors as they
absorb a great deal of heat during testing.
Orbis heat detectors also incorporate
FasTest®.
A flashing yellow LED is not a sign
that the detector needs to be replaced
immediately. The decision to replace
should be taken by the service engineer,
taking the environment of the detector into
account. If the detector is not replaced it
will evenually cause false alarms.
When deciding how long to leave the
detector on site in such a case, the
following rule of thumb may be used:
installation time + 25%
For example, if a detector had been
installed for four years when the LED
flashed yellow, it could be left in place
for up to 12 months.
Dirty detectors can be returned to Apollo
for cleaning and recalibration.
