EACIE Evacuation Alert Control and Indicating Equipment
4 CABLING REQUIREMENTS
All installation wiring must be checked and tested before termination at the panel. Always isolate the
panel's mains and battery backup supplies before cable termination at the panel.
4.1
Mains Wiring
Mains wiring must be installed in accordance with all applicable national, regional or local standards. In the
UK this is BS 7671 IET Wiring Regulations and BS 8629 Clause 15.
Mains wiring should be standard or enhanced fire-resistant and segregated from extra low voltage field wiring.
The general requirement for the 230V, 50Hz mains supply to the EACIE panel is fixed wiring, using 3 core cable
2
(no less than 1mm
and no more than 2.5mm
fused spur, fused at 3A or a 6A Type B circuit breaker to IEC/EN 60898-1.
The mains supply MUST be exclusive to the panel and be reliably earthed at the indicated earthing post.
The number of isolating devices between the incoming power supply to the building and the EACIE panel's PSU
should be kept to a minimum.
As an alternative to a switched fused spur, a double-pole isolating switch (B) with 3mm air gaps on the
contacts & switching L & N only, may be used in the mains feed from the Main Distribution Board (A) to
the EACIE panel (C), providing it meets the appropriate wiring regulations - see diagram below.
4.2
Field Wiring
Separated or Safety Extra-Low Voltage (SELV) field wiring includes loop circuits and auxiliary inputs/outputs.
SELV field wiring must be installed in accordance with the relevant national, regional or local regulations.
In the UK this is the BS 7671 IET Wiring Regulations and BS 8629 Clause 15.
2-core screened, enhanced fire-resistant cable (≥ 1mm
only shields the data moving up and down the cables from outside interference but is essential to ensure
compliance with EMC regulations. All screens must only be terminated to the earth bar provided in the panel's
chassis.
Screened cables such as FP 200™, Firetuff™, Firecel™ and MICC may be acceptable provided they meet
national standards / the system specification as applicable.
4.3
Testing of Field Wiring
Check the continuity of the loops (including screens), loop earth faults, loop crossover faults and the resistance of
all other field wiring as appropriate to ensure they are free from faults.
DO NOT test wiring with an insulation tester (Megger) with any electronic equipment connected as the
500V test will destroy these devices and invalidate the warranty.
