2. FIRST FIX
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.
2.1 RECOMMENDED CABLE TYPES AND THEIR LIMITATIONS
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 1mm
2
cross section
On the Optima Panel the general recommendation would be to use standard fire resistant cable, such
as Firetuff
™
, FP200 or an equivalent. These cables are screened, and will provide good ECM
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).
2.2 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 inside the FACP.
2.3 DETECTOR CIRCUIT WIRING DIAGRAM
The Premier SX comes with one, two, four, six or eight Detection circuits (Zones). A maximum of 32
devices (i.e. smoke detectors, heat detectors, or Manual Call Points) can be fitted to each circuit.
ALL DEVICES MUST BE POLARISED.
