PREMIER SX INSTALLATION MANUAL.
2. FIRST FIX
All system wiring should be installed to meet BS5839: Pt1: 1988 and BS 7671 (Wiring
Regulations). Other National standards of installation should be used where pertinent.

2.1 CABLE TYPES AND LIMITATIONS

To shield the Panel from outside interference and ensure compliance with Electro Magnetic
regulations, we recommend screened cables are used throughout the installation.
According to BS5839: Pt1: 1988 "Fire Detection and Alarm Systems for Buildings (Code of Practice
for System Design, Installation and Servicing)", there are two categories of cable:
Category 1: Required to operate for prolonged periods during Fire Conditions.
Category 2: Not required to operate for prolonged period during Fire Conditions.
Cables deemed suitable as Category 1 can be used as Category 2, but NOT vice-versa.
According to BS5839: Pt1: 1988, cables complying with BS6387 Categories C, W, Z (i.e. FP200
Firetuff, Firecell, MICC) can be used for both categories (1 & 2). All the aforementioned cables
are acceptable as being shielded providing they are properly terminated at the Panel. However, the
System specification may demand the use of a particular type of cable and due regard should be paid
to this fact.

2.2 MAINS WIRING

The requirement for the Mains supply to the Fire Alarm Panel is fixed wiring, using 3-core cable (no
less than 0.75mm² and no more than 2.5mm²) or a suitable 3-conductor system, fed from an isolating
double pole switch fused spur, fused at 3A. This should be secure from unauthorised operation and
be marked 'FIRE ALARM: DO NOT SWITCH OFF'. The Mains supply must be exclusive to the Fire
Panel. MAKE SURE ANY SPARE ENTRY HOLES ARE COVERED WITH THE PLASTIC
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.

2.3 DETECTOR CIRCUIT WIRING

Depending on the model purchased two, four, six or eight Detector circuit connections are available
on the Fire Alarm Panel. A maximum of 32 devices (i.e. smoke detectors, heat detectors, or Manual
Call Points) can be fitted to each circuit.
