1.INTRODUCTION
THIS FIRE ALARM CONTROL PANEL IS CLASS 1 EQUIPMENT AND MUST BE
EARTHED
This equipment must be installed and maintained by a qualified and technically experienced person.
1.1 HANDLING THE PCBS
If the PCBs are to be removed to ease fitting the enclosure and cables, care must be taken to
avoid damage by static.
The best method is to wear an earth strap, but touching any earth point (eg building plumbing) will help to
discharge any static. Hold PCBs by their sides, avoiding contact with any components.
Always handle PCBs by their sides and avoid touching the legs of any components. Keep the PCBs away from
damp dirty areas, e.g. in a small cardboard box.
1.2 USING THIS MANUAL
This manual explains, in a step-by-step manner, the procedure for the installation of the Premier AD Range of
Fire Alarm Control Panels. For full operational and maintenance information, please refer to document
GLT.MAN-106 (USER MANUAL, MAINTENANCE GUIDE & LOG BOOK). It also contains a System set-up
table, and Installation Certificate, that must be completed by the Commissioning Engineer prior to system
handover.

2.PREMIER AD OVERVIEW
2.1 PANEL DESCRIPTION & DESIGN CONCEPT
The Premier AD is a 2-loop analogue addressable fire alarm control panel designed to EN54 part 2 &
4. It has 2 addressable loops, each capable of having 126 devices.
The Premier AD has 4 conventional sounder circuits, which are always configured as common
sounders. They will activate with an alarm from any zone.
The loop sounder outputs (loop powered sounders, & sounder circuit controllers) can be set up as
zonal, or common.
If the sounder is in a zone that contains a detector or input module, then that sounder will be zonal,
and will only activate with an alarm in that zone.
If the sounder is in a zone that only contains output devices, then it will be common, and will activate
with any alarm.
The exception to this rule is a priority Call Point, which will start all sounders, even if they are set up
as zonal.
It has been designed to give the advantages of an addressable system, with the simplicity of a
conventional system. To help achieve this, the Premier AD uses default values to cut out many of the
programming steps normally associated with addressable panels. It also uses its LEDs as the
Primary source of information, so in most cases, there is no reason to look at the screen, or access
any menus. The screen is simply there to identify loop device fault locations, and to help in setting up
the panel.

While all options are programmable on our larger Premier AL panel, the Premier AD uses
preconfigured settings for most options.
Device sensitivity and pre-alarm levels are preset.
To simplify configuration, there is no zone allocation programming. Instead each loop is split into 8
zones, and each device is assigned to a zone by the address set with its 8 way dip switch.
The loop sounder operation is either common or zonal depending on the sounders address.
This leaves only the device label to be programmed by the installer.

2.3 IMPROVEMENTS FROM V1 CPU CARD
This version of the Premier AD has an upgraded CPU board to the previous version. The
improvements include:-
•Real time clock
•Event Log (2048 events)
•Printer port (RS232)
•Repeater port on CPU card (for use with Simplicity Panel)
•Improved fault messages
•Improved call point identification (Panel now identifies a call point alarm immediately)
•Improved sounder base starting & stopping time
•Option to disable individual points or whole zones
•Detector LED & sounder can be operated from the menu to help identify devices
•Panel software version can be viewed through menu.
To determine which version of CPU card is fitted to a panel, compare to the pictures below:-
Old CPU – 3 large ICs New CPU – 2 small surface mount ICs
If the control panel has the OLD CPU card, then some of the options in this manual will not be
applicable. Contact your supplier to obtain Version 1 manuals.
The upgraded CPU card can be retrofitted to a Premier AD with an earlier version card. Contact your
supplier for details.
3. DESIGNING THE SYSTEM
Designing a Premier AD System is a fairly straightforward matter. It just takes a bit of thought to zone
allocation during the system design stage.
1. Decide on the zone allocation for the system. Each zone can have a maximum of 16 devices fitted.
Consider the simplified 3-storey building below.
GROUND FLOOR
FIRST FLOOR
SECOND FLOOR
ZONE 1: DEVICE ADDRESS 1 TO 16
ZONE 2: DEVICE ADDRESS 17 TO 32
ZONE 3: DEVICE ADDRESS 33 TO 48
ZONE 7: DEVICE ADDRESS 97 TO 112
ZONE 4: DEVICE ADDRESS 49 TO 64
ZONE 5: DEVICE ADDRESS 65 TO 80
ZONE 6: DEVICE ADDRESS 81 TO 96
The advantage of this method of zone allocation is that it simplifies the panel setup by eliminating a
programming stage.

PREMIER AD INSTALLATION MANUAL. Software Version :PANEL-R1578 & LOOP-R1062
Approved Document No: GLT.MAN-105A PAGE 5
Issue : 2.02 Authorised: GH Date: 16/07/2007
The main disadvantage of this method of zone allocation is the maximum zone capacity of 16 devices
If a zone has more than 16 devices it will need to be split into smaller zones.
Similarly, a zone with only one device would leave 15 empty addresses on that zone.
This will not cause a problem if it is considered at the system design stage.
2. Decide if the sounders need to operate common or zonal. If they are to be common, then there are
three options to decide between:
i. Conventional sounders connected to the 4 conventional sounder circuits
ii. Fyreye sounder bases connected to the addressable loop.
iii. Addressable stand alone sounders in a zone without any detectors, call points or
input units. (In the example above, zone 8 could be used for common loop sounders:
address 113 to 126, which allows 14 devices)
Each option has advantages & disadvantages. Check the Sounder option chart on page 15 for
information.
3. If zonal sounder operation is required, loop controlled sounders must be used. They should have
addresses within the zone that contains the detectors that will activate them. During an alarm, after a
preset delay of 3 minutes, all addressable sounders will start.
Note: The cabling to addressable sounders can be the same whatever method of operation is used.
The devices DO NOT have to be numbered sequentially on the loop. The sounders can be changed
between zonal and common, provided there are free addresses to change the sounder’s zones.
4. Whenever possible, give each device as descriptive a label as possible. The better the description,
the easier it is to locate in the event of an alarm. The panel allows 20 characters. It may be necessary
to use abbreviations to achieve the required label.
5. Keep the design of the system, and any changes to it well documented. This makes it easier to
trace any configuration errors during installation & commissioning.

4. FIRST FIX
4.1 Mounting the Control Panel
The control panel should be installed in accordance with the following recommendations:-
•The panel should be close to the main entrance of the building, so that it can be viewed
by any fire-fighting personnel entering the building.
•It should be fitted to a sturdy wall that will not flex unnecessarily.
•It should be mounted at eye level, in order for it to be viewed without need of a ladder.
•It should be installed in a dry, weatherproof place, preferably NOT in direct sunlight.
•It should be easily accessible, so that the responsible person can perform their regular
fire alarm checks.
4.2 RECOMMENDED CABLE TYPES AND THEIR LIMITATIONS
All wiring must be installed to meet BS5839: Pt1: 2002 and BS 7671 (Wiring Regs) standards.
Other National standards of fire alarm system installation should be adhered to where
applicable.
Screened cables should be used throughout the installation to help shield the Panel from outside
interference and ensure EMC compatibility.
The two categories of cable according to BS5839: Pt1: 2002, Clause 26 “Fire Detection and Alarm
Systems for Buildings (Code of Practice for System Design, Installation and Servicing)” are:
Standard fire resisting cable – to PH30 classification of EN 50200
Enhanced fire resisting cable – to PH120 classification of EN 50200
(Note that all cables should be at least 1mm2cross section
On the Premier AD Panel the general recommendation would be to use standard fire resistant cable,
such as GLT Exports Fire Defence Cable, Firetuff™, FP200 or an equivalent. These cables are
screened, and will provide good EMC shielding when properly grounded at the panel. Certain system
specifications may demand the use of a particular type of cable and due regard should be paid to this
fact.
Depending on the environment, the cables may need mechanical protection (such as a conduit).
4.3 MAINS WIRING RECOMMENDATIONS
The Mains supply to the FACP is fixed wiring, using Fire resisting 3-core cable (Between 1 mm² and
2.5mm²) or a suitable 3-conductor system, fed from an isolating double pole switch fused spur, fused
at 3A. IT SHOULD NOT BE CONNECTED THROUGH AN RCD. This should be secure from
unauthorised operation and be marked ‘FIRE ALARM: DO NOT SWITCH OFF’. The supply must be
exclusive to the Fire Panel. MAKE SURE ANY SPARE ENTRY HOLES ARE COVERED WITH THE
GROMMETS PROVIDED
For information on how to connect Mains to the Panel’s Power Supply PCB, see page 8.
Also refer to rating information on the mains cover inside the FACP.

5. MOUNTING THE FIRE ALARM PANEL
The Premier AD comes with many cable entry holes. If another entry hole is required, it is strongly
recommended that the panels door be removed to avoid accidental damage. Also, the termination
PCB should be removed and stored in a safe place. This would also help while fixing the back box to
the wall.
5.1 PLANNING CABLE ENTRY
Fig.2 below shows the location of the cable entries to facilitate planning of wiring (home runs) to be
brought to the panel.
The grommets can be easily removed by a push from inside the control panel box.
If a grommet is removed, fill the hole with a brass cable gland. If any knockout is removed, but
subsequently not used, it should be covered up.
The 230Va.c. Mains cable must be fed into the enclosure via one of the cable entries at the top right
corner of the back box. (Refer to “Connecting the Mains” on Page 8).
5.2 FIXING THE BACK BOX TO THE WALL

SUPPLY
Figure 3: Power Supply PCB layout and Mains connection details
6.2 CONNECTING THE BATTERIES
LINK WIRE
Figure 4: Battery location and connection details
The panel should be connected to 220-240V AC by a 3A
rated spur to the fuse box with 1mm2 to 2.5mm2 3-core
cable. Nothing else should be connected to this supply.
The cable should be fire resistant
The Live, Earth and Neutral connections are marked on the
PCB. The Mains is protected by a quick blow 20mm 2A
HBC fuse. (Also known as HRC)
The incoming mains cable should be kept separate from
the zone cables to help minimise mains interference.
Once the mains is connected, the protective cover should
be replaced BEFORE turning on the mains power. This will
minimise the chance of electric shock from the PCB.
MAKE SURE ANY SPARE ENTRY HOLES ARE
COVERED WITH THE PLASTIC GROMMETS PROVIDED
It is advisable to apply power to the panel before
connecting any devices, to check for correct
operation, and to familiarise yourself with the fire
alarm panels controls.
Although there are many sizes of suitable
battery, the sizes we usually recommend for
the Premier AD are 12V 7Ah, or 12V 12AH
To calculate the exact requirement, use the
equation in section 16, BATTERY
CONNECTIONS
The two batteries are wired in series.
The +ve of one battery is connected to the red
battery lead.
The –ve of the other battery is connected to
the black battery lead.
The –ve of the first battery is connected to the
+ve of the second battery using the link wire
supplied.
When fitting the batteries, take care not to
damage the temperature monitoring
thermistor. This is used to prevent
overcharging the batteries in high ambient
temperatures.

7 ADDRESSABLE LOOP WIRING
The Premier AD comes with two addressable loops. Addressable detectors, addressable call points, addressable
loop powered sounders and several other interface units can be connected to these loops. A MAXIMUM OF 126
DEVICES CAN BE CONNECTED TO EACH LOOP. We recommend that the first and last devices on a loop have
isolator bases fitted. Also the last device on each zone should have an isolator fitted. This is to prevent a short
circuit fault in one zone effecting another zone.

A maximum of 32 loop-powered addressable sounders or sounder bases are permitted on the loop. On the Premier
AD Panel, all Sounder Bases are always configured as common sounders.
Short circuit isolators should be used to prevent loosing the whole loop in the event of a single short circuit fault.
They should be fitted to each zone boundary, such that any short circuit will only affect the devices in 1 zone.
The termination of each wiring circuit must be as indicated on the main PCB (See page 31). The Earthing of the
cable screens should be as shown on page 17
Pre-Commissioning Cable Checks
1. +ve in to +ve out less than 24 ohms
2. -ve in to -ve out less than 24 ohms (may need to temporarily disable isolators to measure)
3. +ve to –ve greater than 500k ohm
4. +ve to Earth greater than 1M ohm.
5. -ve to Earth greater than 1M ohm.
6. +ve to –ve less than 50 mV pickup (on AC & DC scales)
Note that some Devices
(for example, a sounder
controller circuit) may
require a separate 24
volt supply to operate.
