1 ABOUT THIS PANEL
1.1 PRODUCT OVERVIEW
The QuickZone XL panel is available from 4 to 12 Conventional and/or Twin Wire (sav-wire) zones.
For the fire alarm engineer, the QuickZone XL has been designed to minimise labour costs by providing ample
room for tasks such as wiring and changing batteries. Activation is via key switch or access code, which means
you should always be able to work on the panel and the one man walk tests will help reduce the cost of
maintaining the fire alarm system.
Simplicity is one of the most important aspects when considering the end user of a fire alarm panel. The colour
coded buttons and the 3 step silence functionality gives non-technical people the confidence to correctly
manage their fire alarm system.
All inputs and outputs are fully programmable and there are options to have delays to the outputs. The
programming features of the QuickZone XL also include 3 different modes to help reduce false alarms. Local
fire authorities are demanding this type of functionality to reduce unwanted callouts from alarm receiving centres
As standard, all QuickZone XL panels provide two monitored sounder circuits, Fire & Fault VFCO relays, Fire &
Fault switched negative outputs, class change and an alert input.
A fully functional repeater panel is available via a plug in comms PCB.
QuickZone XL panels support a large range of conventional detectors including, Apollo, Hochiki & Nittan.
The panels are supplied with a 3.0 amp internal power supply module. This module complies with the
requirements of EN54-4 : 1988 and provides temperature compensated battery management charging.
QuickZone XL panels are approved to European standards EN54-2 & 4, Fire Detection and Alarm Systems –
Control & Indicating Equipment.

2 DESIGN CONSIDERATIONS
2.1 SYSTEM DESIGN & PLANNING
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 limited extent.
• 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.
Beacons
• Visual alarms such as beacons should always be mounted at a minimum height of 2.1m from floor level.
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.
A few handy tips

13
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).
2.1.1 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.
2.1.2 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.
2.1.3 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 undetaken to ensure devices are working within
specified limits.
2.1.4 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 unauthorised 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.

3.2 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 pcbs. These wrist
straps are designed to prevent the build-up of static charges, not only within a person’s body,
but on many other materials.
ESD damage is not always evident immediately; faults can manifest themselves at any time in the future.
All pcbs should be stored in static shielded bags (silvered) for safe keeping, when not mounted in the control
panel.
3.3 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.
3.4 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.

Typical panel layout
Drawing shows typical internal layout of the panel cabinet with two 3.2Ah, 12v batteries fitted
3.5 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.

3.6 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 optimise 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 AC Mains is connected before the batteries, the panel will show a Power Supply fault for up to 1 minute
until the monitoring cycle has finished polling. This is normal. If the fault doesn’t clear after 1 minute, check
connections.
3.7 BATTERY CHARGING VOLTAGE CHECKS
The battery charging voltage is factory calibrated to 27.3VDC +/- 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 & 0V supply output terminals. With the batteries disconnected the
voltage should be 27.6VDC +/- 0.2V @ between 11oC - 40°C.
c) To test the batteries, turn off the mains and see if the system will run on the batteries. Check the battery
voltage. This 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 17), 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.

4 SETUP & PROGRAMMING
4.1 TWIN WIRE MODE
What is Twin Wire?
Twin Wire is what is often referred to as Sav Wire. The technology enables sounders and beacons to be
connected to the same circuit as the detectors and call points. This can result in greatly reduced installation time
and cost.
How does it work?
In Twin Wire configuration the fire zone circuits reverse polarity in alarm condition to power the sounders and
beacons. For this reason the sounders and beacons need to be wired in opposite polarity to the detectors and
call points, i.e. zone positive wire connects to detector base and call point positive terminals but sounder and
beacon negative terminals.
Twin Wire systems require special ‘sav-wire’ detector bases and polarised call points but standard sounders.
Most modern, non-addressable, low current, polarised sounders, bells and beacons are compatible, Cooper
Fulleon, Besson, Klaxon etc.
To set Twin Wire mode for zones 1-4 on the main circuit
board, move switches 1-4 on the 7 way DIL switch located on
the main PCB to the ‘ON’ position.
Each zone can be independently set to Twin Wire, switch 1
relating to zone 1 etc.
To set Twin Wire mode for zones A-D on the zone extension circuit
boards, move switches A-D on the 4 way DIL switch located on the
zone card to the ‘ON’ position.
Each zone can be independently set to Twin Wire, switch A relating
to zone A etc.
