Product specifications

FIRST FIX
A
ll system wiring should be installed to meet BS 5839 Part 1 and BS 7671 (Wiring Regulations).
Other national standards of installation should be used where applicable.
Cable types and limitations
Consult Clause 26 of BS 5839 Part 1: Fire detection and fire alarm systems for buildings - code of practice
for system design, installation, commissioning and maintenance, for detailed information on cables,
w
iring and other interconnections.
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 fire-resistant screened cables throughout
t
he installation.
Correct cable glanding is essential and due regard should be made to any system specifications which
demand a certain cable type.
Mains wiring
The requirement for the Mains supply to the fire panel is fixed wiring, using three core cable (no less than
1mm
2
and no more than 2.5mm
2
) or a suitable three conductor system, fed from an isolating switched 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.
(As an alternative to a switched fused spur, a double pole isolating device may be used providing it meets
the appropriate national wiring regulations - see diagram below.)
Do not drill any additional holes
for cable entry in this shaded area.
This is where the PCBs and
backup batteries will be located.

Planning the cable layout in the panel
The detector and sounder circuit cabling is classed as extra low voltage and should be segregated away
from Mains voltages. Careful planning is needed to ensure this, see figure 2 (below) for guidance. Drill
centre points are provided in the panel base to aid drilling tools. Cut out suitable holes in the panel using
a hole saw directed by a pilot bit in the centre of the hole saw. Always ensure that if a hole is cut out it is
filled with a good quality cable gland. Any unused holes must be securely blanked off.
