4.1 Cabling Instructions

All wiring should comply with current wiring regulations or the applicable local wiring regulations. Note also the requirements of EN54-14 (UNE 23007/14)
for cabling and interconnection of a fire detection and alarm system.
For information on wiring inputs and outputs and wiring instructions to identify terminals, refer to Section 4.3, on Base PCBB wiring connections clause.
Use the following rules when installing cables:
1. Cables should be brought into the enclosure using the 20mm cable entry points provided on the top face and back of the enclosure. Ensure that all
openings in the enclosure are closed before connecting power to the panel to prevent inadvertent access to hazardous voltages.
2. Tails should be of sufficient length to connect to the appropriate termination points at the commissioning stage.
3. Cable conductor size should be a minimum of 0.5mm2. Terminals accept one 0.5 to 2.5mm2 stranded or solid conductor.
4. Cables should be screened or metal coated and the screens terminated into the earthing points provided within the enclosure to meet EMC requirements
defined by European Directives and to preserve the integrity of the screen connection.
5. Use insulation sleeving on the tails between the cable entry position and the earth post. Run the tails close to the rear wall of the back box.
6. The supply to the panel must be provided with a suitable and readily accessible, double-pole, mains-disconnect device. The mains supply must be
suitably fused and rated according to the specifications.
7. The cable entry points on the extreme left-hand side of the enclosure should be used for mains cable entry. DO NOT route mains cables using any
other cable entry points and ensure that the mains wiring is always separated from the low voltage wiring.
8. All low voltage cables should have a minimum 300Vac rating.
All cables (Mains supply, zone and sounders wiring) of fire alarm systems should be separated from other cables. The distance should be suitable to
prevent mutual interference or damage. "(EN 54-14, section. 6.11.1).
Cables must meet all the requirements specified by the manufacturer or supplier of the equipment. Pay attention to the load capacity and signal
attenuation data. It is essential to follow manufacturer instructions for each cable with respect to the elimination of voltage spikes "(EN 54-14, section
6.11.2)"
