DESIGN CONSIDERATIONS
SYSTEM DESIGN & PLANNING - A few handy tips
What is a detection zone?
In order to direct those responding to a fire alarm signal, particularly the fire service, to the area of a fire, all
buildings, other than very small buildings, need to be divided into detection zones. Detection zones need to
be small enough for a fire to be located quickly.
• If the total floor area of the building is greater than 300m2, each zone should be restricted to a single
storey.
• If the total floor area of the building is less than 300m2a zone may cover more than a single storey.
• For voids above or below the floor area of a room, these may be included within the same zone of the
room, provided that the void and the room constitute a single fire compartment
• The floor area of a single zone should not exceed 2000m2.
Detectors
• A person searching a zone for a fire in a non-addressable fire system should not have to travel more
than 60m to identify the source of a fire
• The sensing element of a smoke detection device should not be less than 25mm and not more than
600mm below ceiling
• The sensing element of a heat detector should not be less than 25mm and not more than 150mm
below ceiling
• When mounted on a flat ceiling, smoke detection devices have an individual coverage of 7.5m radius.
However these radii must overlap to ensure there are no ‘blind spots’. Therefore individual coverage
can be represented by a square measuring 10.6m x 10.6m giving an actual coverage of 112m2per
device
• When mounted on a flat ceiling, heat detection devices have an individual coverage of 5.3m radius.
However these radii must overlap to ensure there are no ‘blind spots’. Therefore individual coverage
can be represented by a square measuring 7.5m x 7.5m giving an actual coverage of 56.3m2per
device.
Call Points
• A person should not have to travel more than 45m along an escape route to reach a Manual Call Point
(25m if disabled person to operate, or rapid-fire development is likely). Manual Call Points should be
sited at all stair wells and exits from the building.
• The frangible element of the manual call point should be positioned 1.4m (+/-200mm) from the floor
level. (Unless a wheelchair user is likely to be the first person to raise the alarm).
Sounders
• Sounder device cabling should be arranged so that in the event of a fault, at least one sounder will
remain operational during a fire condition.
• The minimum sound level should be 65dB(A) or 5dB(A) above a background noise which is louder
than 60dB(A) (if lasting more than 30 seconds) and at a frequency of between 500Hz and 1000Hz.
The maximum sound level should not be greater than 120dB(A) at any normally accessible point. This
may be reduced to 60dB(A) in stairways, enclosures up to 60m2and specific points of limitedextent.
• For areas where people are sleeping, sounder devices should produce a minimum 75dB(A) at the
bed-head with all doors shut. In buildings providing sleeping accommodation for a significant number
of people, all bedrooms should have both audible and visual alarms.
This guide is intended as an aid to
designers and installers of fire
detection systems. It is NOT to be
used as a substitute to BS5839
which should be read in full.

Approved Document Ref: UI-CFX-Plus-PS-02 Issue 1.0
DESIGN CONSIDERATIONS
Beacons
• Visual alarms such as beacons, should always be mounted at a minimum height of 2.1m from floor
level.
General
• Fire Alarm Control Panels should be installed at a location appropriate for staff and fire fighters
• All mains supply isolators must be double pole and suitably marked
• All joints to be fire resisting, junction boxes to be labelled ‘FIRE ALARM’.
• All cables to be fire resisting with a minimum cross-sectional area of 1mm2.
• Cable using trunking as a means of containment must be clipped using fire resistant supports WITHIN
THE TRUNKING.
• Zone charts should be fitted in all appropriate locations (adjacent to control equipment and repeaters).
CABLE TYPES & LIMITATIONS
To comply with EMC (Electro Magnetic Compatibility) regulations and to reduce the risk of electrical
interference in the system wiring, we recommend the use of screened cables throughout the installation.
Acceptable, commonly available, screened cables, which can be used on both the sounder and detector
circuits include, NoBurn™ FP200™, Firetuff™, Firecel™, MICC (Pyro™) or any other cable complying
with BS 6387 categories C, W, Z. Refer to BS 5839 pt1 clause 26 for detailed information on cables wiring
and interconnections.
CABLING
Suitable cables should be brought into the cabinet using the knockouts provided via a suitable cable gland
recommended for use with that cable. The screen or drain wire of circuits should be bonded to earth at
one location only, and should be continuous throughout the circuit. Drain wires should be terminated in the
cabinet using the earthing terminal provided.
CABLE LENGTHS
The maximum recommended cable length for a zone or sounder circuit is 1Km. This, however, is highly
dependent on the number and type of devices connected.
If in doubt, cable load and resistance calculations should be undertaken to ensure devices are working
within specified limits.
MAINS PROVISION
The mains supply to the fire alarm panel should be hard wired, using suitable three core cable (no less
than 1.0 mm² and no more than 2.5mm²) or a suitable three conductor system that meets the appropriate
national wiring regulations. The panel should be fed from an isolating switched fused spur, supplied directly
from the Main Distribution Board, fused at 3A. This should be secure from unauthorized operation and be
marked ‘FIRE ALARM’.
The mains supply must be exclusive to the fire panel.
As an alternative to a switched fused spur, an appropriately fused double pole isolating device may be
used providing it meets the appropriate national wiring regulations.
All system wiring should be installed to meet BS5839 Pt 1 : 2002 and BS7671
(Wiring Regulations). Other national standards of installation should be used where
applicable.

INSTALLATION
ESD PRECAUTION
Electronic components are vulnerable to damage by Electrostatic Discharges (ESD). An ESD wrist strap,
suitably grounded, should be worn at all times when handling PCB’s. These wrist straps are designed to
prevent the build-up of static charges, not only within a persons body, but on many other materials.
ESD damage is not always evident immediately, faults can manifest themselves at any time in the future.
All PCB’s should be stored in static shielded bags (silvered) for safe keeping, when not mounted in the
control panel.
GENERAL
Care should be taken with regards to avoiding the close proximity of high voltage cables or areas likely to
induce electrical interference. Earth links should be maintained on all system cables and grounded in the
control panel. The detection and sounder circuit cabling is classed as extra low voltage and must be
segregated away from mains voltage.
• Any junction boxes used should be clearly labelled FIRE ALARM.
• Any ancillary devices, e.g. door retaining magnets, must be powered from a separate power source.
• Any coils or solenoids used in the system must be suppressed, to avoid damage to the control
equipment.
MOUNTING THE CABINET
The site chosen for the location of the panel should be clean, dry and not subject to shock or vibration.
Damp, salt air or environments where water ingress or extremes of temperature may affect the panel must
be avoided. The temperature should be in the range -5° to +40°C, and the relative humidity should not
exceed 95%.
Before mounting the cabinet remove the main PCB.
Remove the power supply module connecting wires from the main PCB, taking care to note where to re-
connect them. The main PCB can then be carefully pulled off it’s mounting clips.
Secure the cabinet to the wall using the four indented holes in the back box. Ensure the box is mounted
level and in a convenient location where it may be easily operated and serviced.
External cables should be glanded via preformed knockouts at the top and rear of the cabinet. Remove
any knockouts and ensure the cabinet is clear of swarf etc. prior to refitting the PCB. Always ensure that if
a knockout is removed, the hole is filled with a good quality cable gland. Any unused knockouts must be
securely blanked off.
Knockouts should be removed with a sharp tap at the
rim of the knockout using a flat 6mm broad bladed
screwdriver.
Use of excessive force will damage the enclosure
around the knockout.

INSTALLATION
Typical panel layout
Drawing shows typical internal layout of a 12 zone panel with two 7.0Ah, 12v batteries fitted
MAINS CONNECTIONS
Do not connect the mains supply to the panel
until you are fully conversant with the layout
and features of the equipment.
A rating plate is attached to the power supply
module describing the nature of the supply
permitted.
The incoming mains supply should be brought
into the panel via one of the knockouts
provided.
A suitable cable gland must be used to secure
the outer sheath of the cable used. The earth
must first be connected to the primary earth
stud (peg) marked with a symbol, using
the ring crimp provided.
Sufficient earth lead should be left to allow Live and Neutral connections to be accidentally pulled from the
terminal block while leaving the earth connection intact.

INSTALLATION
CONNECTING THE BATTERIES
Batteries of even very small capacity are capable of delivering very high currents which can cause fire or
injury, therefore battery connections should be done with caution.
The panel is supplied with battery leads already connected to the battery terminals on the main PCB.
These leads are coloured red for +ve and black for -ve.
2 x 12v batteries should be connected in series
using the white jumper lead provided. See
diagram.
To optimize the service life of the batteries, the
battery charger output voltage varies with
temperature.
N.B.
In the event of mains failure, the battery charger
circuit will protect the batteries from full discharge
by disconnecting them when they reach below
19v. When the mains supply is restored the
batteries will be automatically reconnected.
NOTE:
If the mains is connected before the batteries, the panel will show a Power Supply fault for up to 1 minute
until the monitoring cyclehas finished polling. This is normal. If the fault doesn’t clear after 1 minute, check
connections.
BATTERY CHARGING VOLTAGE CHECKS
The battery charging voltage is factory calibrated to 27.3V DC +/- 0.2V @ 20oC. This should not normally
require adjustment. Where battery problems are experienced, the following information should be
considered.
a) If a battery is disconnected from the charger, no voltage will appear on the output leads or terminals,
due to intelligent battery controls.
b) Check the power supply voltage at the 28V& 0Vsupply output terminals. With the batteries
disconnected the voltage should be 27.6V DC +/- 0.2V @ between 11oC-40oC.
c) To test the batteries, turn off the mains and see if the system will run on the batteries. Check the
battery voltage, should be 26.8v for a good battery or 22v for a flat battery.
d) The power supply voltage can be adjusted using the potentiometer on the power supply module (see
page 9), checking at the 28v & 0v output terminals with a calibrated volt meter. Batteries should be
disconnected and the Access Level 3 DIL switch should be set to ‘ON’ (see page 20), which will
override the temperature compensation controls. Carefully adjust the voltage to 27.6vdc +/-0.2v.
When completed, switch off Access Level 3 DIL switch and re-connect the batteries.
e) When the panel is re-charging a low battery, it should be possible to see the voltage across the
batteries increase gradually. If this is not occurring, the batteries or the panel may be faulty.

SETUP & PROGRAMMING
NETWORK PANELS SETUP
The system can support up to 8 networked control panels, 1 x Master and up to 7 x Slaves.
Comms PCB
To run a network, a Comms PCB (TPCA05) must be fitted to each control panel. Any medium or large
CFX-Plus Pro-Sense panel from 8 to 32 zones with software version 4.0 and above may be used.
The Comms PCB fits into the control panel on top of the main circuit board where the ribbon cable from
the display board comms is normally plugged.
To fit the Comms PCB, power down the panel, un-plug the display board ribbon cable from the main circuit
board and plug the Comms PCB into the socket instead.
A socket is provided on the top of the Comms PCB to re-connect the display board ribbon cable.
Each panel to be included in the network is defined by setting a switch on the main PCB. In the case of the
CFX-Plus Pro-Sense 8-12 this is switch 7 on the 7 way DIL switch. OFF = Stand Alone mode, ON =
Network/Repeater mode.
With this switch in the ON position the panel will automatically recognise & operate the Comms PCB
(TPCA05).
