Rafiki Catalogue - AFA Fire and Security
INTELLIGENT FIRE TECHNOLOGY
Located in Cwmbran, South Wales, Rafiki Protection Ltd is a fully integrated R
& D and manufacturing centre. Producing unique products to meet the
demands of the Fire Protection market for over 10 years, Rafiki development
has been focussed around the “Multipoint” multi-criteria detector which was
first launched in 1994.
Programme of
continual product
developments…
Multipoint technology is at the core of all Rafiki systems. This multi-criteria
detector is available to integrate as part of an intelligent conventional 2-wire
system, and also intelligent addressable systems. Due to the advanced micro
processor control the Multipoint detector uses, along with optical smoke and
high specification thermistor sensors, it gives a highly accurate fire decision.
Rafiki systems have focussed development on finding solutions to the problem
of “nuisance alarms” – where the detector recognises a source of a fire like
phenomenon but it isn’t a “true” fire situation. The Twinflex 2-wire system and
the Sita 200 plus addressable system use pre-alarm features to allow for
‘nuisance alarm filtration’ which Rafiki term as “Checkpoint” technology.
Rafiki’s broad range of products can be categorised as follows:

Fire detection & alarm systems BS5839
Risk assessment
The ‘Fire Precautions (Workplace) Regulations’ require any business
employing five or more persons to hold a written ‘Fire Risk Assessment’
and ‘Emergency Plan’. This must then be periodically reviewed.
The local fire brigade can enforce compliance, and close any building
that does not meet this act.
In the event of a fire in a building without a written ‘Fire Risk
Assessment’, those responsible may face fines and imprisonment,
and/or private litigation.
What the law requires you to do:
A fire risk assessment
should identify:
•
Possible hazards.
•
Sources of ignition.
•
Persons at risk of fire.
•
Means of escape.
•
Fire detection and
alarm systems.
•
Fire fighting facilities.
•
Routine procedure in
the event of fire.
•
Any difficulties with the
above and plans to put
them right.
Intelligent Fire Technology
•
Complete a fire risk assessment for your work place (considering
all employees, the public, disabled people and people with
special needs).
•
Identify and record any significant findings or persons at risk.
•
Provide and maintain fire precautions.
•
Provide information, instruction and training.
•
Nominate persons responsible to implement your emergency plan.
•
Consult employees about the above nominations and your
proposals to improve fire precautions
•
Inform other employers who may have work places in the building
about any significant risks which may affect their safety and cooperate with them to reduce/ control these risks.
•
If you are not an employer, but control premises which contain
more than one workplace, you are responsible for complying with
the fire regulations.
•
You must establish a suitable means of contacting the emergency
services.
•
Your employees must co-operate to ensure the workplace is safe
from fire and its effects.
1
System zoning
In order to aid identification of the source of a possible fire, the
protected building should be divided into ‘zones’. When deciding on a
suitable zoning scheme for a building, consideration should be given
to the size, any existing fire routines, escape routes, zone accessibility,
and structural fire compartmentation.
The following guide lines should be observed:
•
If the total floor area of the building is less than 300m2 then the
building needs only one zone, regardless of the number of
storeys.
If the total floor area is greater than 300m2:
•
The maximum area for a zone is 2000m2.
•
If a stairwell (or similar) extends beyond one floor it should be a
separate zone.
•
If a zone covers more than one fire compartment then the zone
boundaries should follow the compartment boundaries.
•
The search distance in order to ascertain the position of the fire
should not exceed 30m. Remember that the use of Remote
Indicator lamps may help to reduce the distance travelled.
•
If a building is divided between occupiers, zones must not be
shared between them.
Manual call points
A ‘Manual Call Point’ is a device which enables personnel to raise an
alarm in the event of a fire incident by pressing a frangible element to
activate the alarm system.
Manual Call Points should be installed at a height of 1.4m above floor
level at easily accessible, conspicuous positions, on exit routes, at the
entry to floor landings of staircases and at all exits to the open air.
Manual Call Points should be spaced so that one may always be found
within a maximum distance of 30m apart.
Automatic detectors
When deciding on the type of detector to be used in any area it is
important to remember that the detector has to discriminate between a
genuine fire and the normal conditions existing therein, e.g. smoking in
staff rooms, steam from ensuite bathrooms, kitchen fumes, vehicle and
forklift truck fumes in warehouses, etc.
Generally all types of detectors should be sited on the ceiling at the
highest point of the area to be covered. Detectors mounted at greater
heights have a reduced efficiency and in these cases further advice
should be sought.

Intelligent Fire Technology
Smoke detectors general
Detection in apex roofs
In open spaces under flat horizontal ceilings, every
point should lie within 7.5m of a smoke detector.
If the ceiling is pitched or sloping, smoke will tend to
rise towards the highest point (apex) of the roof,
therefore detection should be placed in the apex. As
the slope tends to reduce the delay before smoke or
heat reaches the detectors, it is permissible to use a
greater spacing between the detectors mounted there.
Smoke detection should be generally avoided in the
following areas to avoid unwanted alarms. They
should be protected by means of other detectors such
as heat detectors.
•
Contamination in dusty areas may cause
unwanted alarms and reduce the life of the
detector.
•
Damp or humid conditions such as showers,
bathrooms and external areas should be
avoided as the water vapour may cause
unwanted alarms and reduce the life of the
detector.
The spacing of the smoke detectors in the apex only,
may be increased by 1% for every degree of slope of
the ceiling up to a maximum of 25%.
Fire alarm sounders
•
Detectors should not be mounted where gases,
vapours or fumes are present.
•
Detectors should never be used at low
temperature where ice or condensation can affect
detector sensitivity.
•
Kitchens, garages, welding shops and boiler
houses should generally be avoided.
Heat detectors general
In open spaces under flat horizontal ceilings, every
point should lie within 5.3m of a heat detector.
Fire Alarm sounders should be installed throughout the
building with an even distribution, to generally provide
a minimum sound level of 65dB(A) or 5dB(A) above
any background noise which is likely to persist for
more than 30 seconds.
Where the alarm may have to arouse sleeping persons
e.g. hotel bedrooms, nursing homes, etc, a minimum
sound level of 75dB(A) is required, at the bed head
with all the doors shut.
All fire alarm sounders in a building should produce
the same sound, distinct from any other audible
warning devices in the building.
Where fire alarm sounders are required in extremely
noisy areas e.g., machine shops, it may be necessary
to install additional ‘Visual Indication Beacons’.
Cabling
Heat detectors are designed to either detect a rapid
rise in temperature or to operate at a fixed
temperature. Although they provide a slower response
time than smoke detectors they do provide a method
of protection for areas where smoke detectors cannot
be used.
Heat detectors should not be used for the protection of
life or where extensive property loss may be expected.
‘Rate of rise’ heat detectors
‘Rate of Rise’ heat detectors respond to both rapid
increases of temperature and to a fixed top
temperature.
The operation of a Fire Alarm and Detection System’
depends on the cabling and connections between the
components. It is essential that connection between
Manual Call Points and Detectors function correctly
when they are operated.
Cables within the system are required to function
correctly for significant periods after being attacked by
fire. These include the power supply cables to the
control panel, the detection circuits and the fire alarm
sounder circuits. Thus the cables chosen must be
correctly rated to withstand these conditions.
‘Fixed temperature’ heat detectors
Fixed temperature heat detectors are available with
different temperature settings, and are normally
installed in kitchens, boiler rooms, etc.

User responsibilities
Introduction
Annually
The responsible person is required under BS5839 to
undertake certain tasks with respect to the testing and
maintenance of the fire alarm system.
Each device on the system should be tested for correct
operation as before.
The responsible person is also required to liaise with
the building maintenance personnel to ensure that their
work does not impair or otherwise affect the operation
of the fire alarm system, and to ensure that a clear
space is maintained in the vicinity of detectors, and
call-points remain unobstructed and conspicuous.
Routine Testing
The responsible person should also ensure that the
following routine testing is carried out. If there is a link
to a remote monitoring centre it will be necessary to
advise the centre prior to a test. On larger systems it
may be necessary to isolate building services
interfaces to avoid disruption to the occupants. In any
case the panel should provide audible and visual
indication that parts of the system are disabled.
Any defects should be recorded in the log book and
reported to the responsible person. A certificate of
testing should also be completed and given to the
responsible person.
Action by the user after a fire
Advise the servicing company and arrange for the
system to be tested by them. A certificate of testing
should be issued to confirm the system operation
following the inspection and any remedial work that is
necessary.
Action by the user after any false alarm
The user can assist the servicing company in the
identification of false alarms by observing the
following:
Daily
•
Always make a note of all illuminated indicators
and messages displayed at the control panel.
Check that the panel indicates normal operation and
that any fault is recorded. Also check that the recorded
faults have been dealt with.
•
Try and identify the activated device, ie. Do not
reset the system until the area of the incident has
been inspected.
•
Record any other incidents occurring at the same
time which could affect the system, eg. power
supply failure, building works, etc.
Weekly
Every week, a different Manual Call Point should be
operated to test the ability of the control equipment to
receive a signal and sound the alarm. The results
should be recorded in the log book.
The service organisation will be more likely to trace
the false alarm if the above information is available.
Biannually
Action by the user following a fault
The system should be checked by a fire alarm service
organisation. This may be the system installer or an
approved maintenance company, and is normally
arranged via a maintenance agreement which
specifies the number of visits and the level of service.
The agreement should also cover non-maintenance
visits, eg. call outs to attend faults, etc.
The standard specifies a number of maintenance tasks
which include a visual inspection of the installation to
ensure that there are no alterations or obstructions
which could affect the operation of the system, and
functional checks to confirm the operation of the
system.
Any defects should be recorded in the log book and
reported to the responsible person. A certificate of
testing should also be completed and given to the
responsible person.
4
Intelligent Fire Technology
When a fault is reported by the control panel, the user
should note all illuminated LEDs, and the circumstances
at the time the fault occurred, and report to the
servicing company.
The service company will be able to advise if the
system is still able to respond to a fire alarm or
whether extra vigilance should be observed until the
fault is rectified. Faults should not be left unreported.
Multipoint Detector
central to all Rafiki systems
Multi-criteria detector, micro-processor control and
integral sounder
The Multipoint detector offers the
following modes of detection:
SMOKE 1
Used where ionisation detectors are normally
fitted especially when there are high ceilings or
a risk of free burning fires (chemical stores
etc), or fires that need to be detected extremely
quickly
SMOKE 2
Used where optical detectors are normally
fitted when there is a risk of a smouldering fire
and for escape routes
SMOKE 3
This setting is designed for use in areas that
are prone to nuisance alarms. The reduced
sensitivity linked with a time delay feature
means that a higher concentration of smoke
needs to be present for a constant time period,
before a fire decision is made. This setting, for
example, is ideal for hotel bedrooms with ensuite shower rooms, the end user can change
the setting from smoke 2 to smoke 3 if
nuisance alarms are becoming a problem –
whilst still offering optimum protection of a
smoke detection setting, especially if this is
what has been specified.
HEAT 1 (Rate of Rise)
Used where a standard rate of rise detector
would normally be used
HEAT 2 (Standard Fixed Temperature 58ºC approx)
Used where a standard fixed temperature heat
detector would normally be fitted, suitable for
kitchens etc
HEAT 3 (High Fixed Temperature 90ºC approx)
Used where a high fixed temperature heat
detector would normally be fitted, suitable for
boiler rooms etc.
Intelligent Fire Technology
The “Multipoint” detector has set new standards in detector technology,
using microprocessor control even as a conventional detector and
offering the installer a full range of detection capabilities with audible
warning in one compact device. Specifiers and installers who choose
the Multipoint detector, do so secure in the knowledge that the fire
detection performance of the detector can be matched to the
environment in which it is installed – and changed any time during the
lifetime of the installation. The mode of detection required can be
simply changed by configuring the DIL switch in the detector electronics
module (also configurable via commissioning software on addressable
systems). All modes are compliant with European detector type
specifications, and are suitable for use in installations compliant with
BS5839: Part 1: 2002, Part 6 2004 if used in conjunction with a
“Twinflex Plus” system.
The Twinflex Intelligent conventional detector can be set to any one of
the above modes as well as a Combined Mode (Smoke 2 & Heat 2)
where a smoke or heat source can trigger a fire decision. This means
the end user is given optimum fire protection, even if the installer is
unsure of the use of the particular area where the detector is sited. As
part of the Twinflex system all Twinflex products including the Twinflex
Multipoint detector feature an End of Line switch, which negates the
need for End of Line resistors.
The Sita Intelligent addressable detector is able to offer all the opposite
choices for detection, set to one mode, or a combination of any listed
to give a choice of up to 15 different settings. It is set via a PC when
programming the system. The Sita Multipoint also has an in-built loop
isolator as well as an I/O for local control and switching – see the
“Sita” section for further details.
The Multipoint Detector also has the unique benefit of an optional full
specification integral sounder. A 90dBA output can be achieved. The
Twinflex Intelligent conventional detector can be set to 3 different sound
patterns, as well as switched off, with 2 sound output levels. The Sita
Intelligent addressable detector has 7 different sound patterns and 3
volume settings.
To ensure the detection capabilities of the Multipoint are never
compromised it self-calibrates every 6 hours. It continuously monitors
for dust contamination, until, over a period of time depending on the
environment it reaches a point where the chamber becomes saturated.
Before this can develop into a false alarm situation, the panel will
indicate that a Multipoint needs attention on both the Twinflex and Sita
systems. To make maintenance easy, the Multipoint features a
disposable optical chamber. This means the chamber can be simply
thrown away, and replaced economically when necessary.

Intelligent Fire Technology
The Twinflex conventional fire alarm system
incorporating the Multipoint combined smoke and
heat detector with built-in sounder means the whole
system can be installed using only one pair of wires
Using the Multipoint detector as part of the Twinflex 2-wire fire alarm
system means that when a detector is wired in, a sounder is too - with
no extra wiring, therefore greatly reducing the number of points that
need to be installed and the time it takes to install. As Multipoint offers
7 different modes of detection, the installation is made even simpler as
this one device suits all applications. Whatever type of detection is
required, for any part of the installation it can be selected by the flick
of a switch at the time of commissioning. 3 different smoke modes, 2
fixed temperature heat modes, a rate of rise mode and a combination
smoke or heat mode can be selected.
As the Multipoint detector is
available with or without a full
specification integral 90 dBA
sounder (for only a marginal cost
difference) no extra devices need
to be purchased when audible
warning is required. (As the
audibility levels recommended in
BS5839 Part 1:2002.) If extra
sound is required, or, for areas that
do not require detection, then a
choice of several different stand
alone sounders can be used on the same two wires, as well as a call
point /sounder combined unit and a sounder beacon.
The panel has the ability to differentiate between call point or detector
alarm, can accommodate 32 devices per zone, has separate fault
monitoring display for each zone, one man walk test facility and zones
are configured without the need to use resistors or capacitors on
unused zones. To make the Twinflex system even more flexible, Rafiki
can also provide a special Output Unit. It can be situated anywhere on
the zone circuit, and is ideal for connecting to plant shutdown, door
release mechanisms etc.
Repeater panels are also available for the Twinflex system, which use
key switch access and have the facilities of silence, sound alarms and
reset.

manufactured in alternative colours if
required.
Whilst in alarm the flashpoint
synchronisation is uniquely reset every
10 seconds to ensure that the beacon’s
flash rate remains in absolute
synchronicity across the entire system.
Installation is made simple by first
fixing the base and then simply
plugging in the unit.
As with all Rafiki sounders the
flashpoint features an anti-tamper
mechanism to ensure that the device is
only released with the use of the head
removal tool.

Twinflexplus
Eliminates the problem
of nuisance alarms!
What is Twinflex Plus?
With the increasing number of new buildings and conversion of
properties to flats and bed-sits along with greater pressure on
environmental officers to actively enforce the requirements of BS5839 part
6, (The code of practice for fire detection and alarm systems in
dwellings), organisations are constantly looking for a reliable early
warning fire alarm system without the disruption of nuisance alarms. To
satisfy this ever increasing market and tackle the problem of nuisance
alarms, the Twinflex – plus system has been developed.
The revolutionary 2 wire
intelligent conventional fire
detection system – now
incorporating “Checkpoint”
technology and the Multipoint
detector
The key to the system technology is the, already proven, “Multipoint”
multi-criteria detector offering seven different selectable modes of fire
detection in one device, plus a built in 90dBA alarm sounder. Any of
which may be selected at installation by way of DIL switch in the detector.
Each device has the additional facility of a built in end of line fault
monitoring feature eliminating the need for separate modules and call
points have the feature of an optional integral sounder. The biggest
advantage, from an installer’s point of view, is that the system does not
require separate sounders and in addition only requires one pair of wires
to operate all devices on each zone, drastically reducing equipment
requirements, installation time and therefore cost.
What is Checkpoint?
Alarm selection, the main feature of the
Twinflex plus is the ability to set a prealarm in individual rooms or apartments
but at the same time instigate full alarm
should fire be detected in any communal
area. This is made possible by a detector
sounder “logical link” feature. This is the
first time that this feature has been made
available on a conventional system and is
beneficial where two stage alarms are
required.
At the planning stage of installation fire
zones are designated as “dwelling” or “communal”. Detectors in dwelling
zones (e.g. apartments, hotel rooms etc.) are enabled with the “logical
link” feature. This then allows the control panel to be, simply,
programmed with a variable time alarm confirmation period
(1-5
minutes at one minute increments). In the event of a fire being detected in
a dwelling only the local (room) sounder will operate to alarm occupants
of that particular dwelling. The control panel will then carry out a number
of checks over this period (which may be 2 minutes, for example ) to
confirm the detector is still in alarm and is a genuine fire, not a false
alarm generated by cooking fumes, steam etc. If at the end of this
checking period the detector ceases to signal alarm the control panel will
automatically reset the detector/sounder and the system will revert to its
normal state.
If, however, at the end of the confirmation check the detector is still
generating an alarm signal the control panel will instantly sound all
alarms in the building for full evacuation. Detectors sensing fire, or, call
point activation (in any zone) in communal areas instantly generate a full
alarm throughout the building. The control panel meets all the
requirements of EN54-2 and EN54-4:1997. The detector meets the
requirements of EN54-5 and EN54-7 :2000. The sounder meets the
requirements of EN54-3:2001.
Intelligent Fire Technology
NOTE: Twinflex Plus panels are configured to have “Dwelling” or
“Communal” zones at the time of commissioning. Dwelling zones are then
set with the “checking” period - between 1 and 5 minutes.
Rafiki advises that this panel should only be installed and configured by
qualified fire alarm installers or equivalent personnel.

How to use the Twinflex Plus system in an
installation
At the planning stage, fire zones are designated as either
“Dwelling” or “Communal”. Multipoint detectors in the dwelling
zones have the facility to use “checkpoint” technology.
“Checkpoint” technology is the ability to select a checking period for
individual detectors to confirm the smoke/heat detected as a
genuine fire not an unwanted alarm.
This checking period can be selected between 1 – 5 minutes at
commissioning stage after consultation with fire officers or other
authorised bodies.

When a detector alarm is activated on this type of zone, the control
panel enters the fire state and the alarms are activated immediately
throughout the installation.
Single Dwelling per Zone (Zonal confirmation alarm)
eg flats with more than one room
When a detector alarm is activated on this type of zone, all
sounders on the zone are activated and then the control panel
carries out the configured number of confirmation checks. If the
detector alarm is confirmed, the control panel enters the fire state
and the alarms are activated throughout the installation; if the
detector alarm is rejected, the sounders on the zone are silenced,
and the detector in alarm is reset.
Multiple Dwellings per Zone (Local confirmation alarm)
Dwellings requiring a single detector/sounder, e.g. hostel; hall of
residence; hotel rooms; bedsits.
When a detector alarm is detected on this type of zone, the integral
sounder in the detector that generated the alarm signal is activated
and then the control panel carries out the configured number of
confirmation checks. If the detector alarm is confirmed, the control
panel enters the fire state and the alarms are activated throughout
the installation; if the detector alarm is rejected, the sounder is
silenced, and the detector reset.

required.
Whilst in alarm the flashpoint
synchronisation is uniquely reset every
10 seconds to ensure that the beacon’s
flash rate remains in absolute
synchronicity across the entire system.
Installation is simple by first fixing the
base and then simply plugging in the
unit.
As with all Rafiki sounders the
flashpoint features an anti-tamper
mechanism to ensure that the device is

The Sita 200 plus control panel may be
programmed utilising the PC based Sita
OSP programming software.
Sita OSP is the name given to the high
level software package written to
enable the individual configuration of
the Sita 200 plus fire alarm system.
The windows based program allows
the system to be set up for each
application, including the setting of
detection modes, subsequent actions to
be taken and individual sound
patterns.
Much thought has taken place to
implement operations in as simple a
way as possible whilst not losing
flexibility through over simplification.
Complicated arrangements with three
alarm stages may be arranged as
required in order to tailor system
operation to the client’s building or
safety procedures.

Replacing a contaminated detector is
quick, simple and cost effective when
using the Multipoint.
The unique design of the Rafiki
Multipoint detector allows a
contaminated optical chamber to be
easily replaced on site.
The Twinflex and Sita systems offer a
contamination warning at both the
control panel and the device for a
period of time before a chamber has
reached the point where contamination
can lead to false alarms.
A replacement chamber may easily be
installed, allowing the Multipoint to recalibrate itself within minutes to retain
optimum detection performance.

Powerful software gives the capacity to build a
system of up to 32 panels, each with 4 loops,
making Sita Multipoint detector technology
available to customers with systems with up to 50,000 devices. The
Quadnet panel offers extension to the established Sita intelligent
addressable range of products using the existing Sita protocol.
Quadnet has been designed using resources of a renowned design
company, and significant customer feedback, to produce a high
specification system with many unique features. Its appeal will attract
consultants, clients, installers and engineers alike. The standard black
hi-gloss finish of the Quadnet panel has been chosen to reflect the
“state of the art” technology which it encases, the idea being it is a
panel to enhance its surroundings, rather than be hidden away. If,
however, a different look is required the Quadnet panel can be
manufactured in many different finishes including brushed aluminium,
walnut and marble. Commissioning software, the panel menu and key
pad layout are installer friendly, along with ease of access for cable
entry and terminations, making Quadnet a popular choice for
engineers and the end user.
