Wiring and Cable Entry

N/O C N/C 0V +24 OP3 OP2 OP1
See Fig 1 above for cable types. Install wiring in accordance with the relevant national, regional or local regulations (in the UK this is the IEE
Wiring Regs BS 7671 and BS 5839 Part 1. Use enhanced fire-rated cables from the controller to the outstations / NC951 and the power supply.

Test Extension Lines

Test all lines for faults before terminating extension lines to the control unit. Also, test outstation lines using a FITT EVC line tester (see
component list above).
CAUTION: DO NOT use an Insulation Resistance Tester with any devices connected as they will be destroyed and the warranty will be void.
Fit Outstations & NC951 Interface
to Earth terminal
Maximum recommended cable distance to the outstations is 1 km, beyond which audio quality may degrade. For wiring and connection details
N/O C N/C 0V +24 OP3 OP2 OP1
refer to Type A outstation instructions (Doc. No. DCM0003819) and Type B outstation instructions (Doc. No. DAU0302000).

Connect Extension Lines to the Control Equipment

Do not connect extension lines to the ECU-4/ECU-8, or optional ECU-8S, until they have been tested, fault-free and suitable cable glands fitted.
Connect extension lines directly to the Exchange PCB (see Fig 2 left). Connect screens to the earth terminal in the back of the enclosure.

Location

6.1
Site all equipment indoors in well-lit areas, free from obstruction. If background noise exceeds 40 dBA,
use an acoustic hood. Site control unit(s) in the control room or lobby, 1.4 metres above final floor level
(FFL). Fit Type A (fire telephone) outstations in fire fighting lobbies and fire access points, 1.3 to 1.4
metres above FFL. Fit type B (disabled refuge) outstations in disabled refuges, 0.9 to 1.0 metre above FFL.

Mounting

7
Remove base PCBs before first fix installation to protect them and expose the base mounting holes.
Wall mount the control units, either surface or semi-flush. Fix the base securely onto a wall using No.8
round-head, or countersunk screws. If an optional ECU-8S is fitted make the interconnections to the
ECU-4/ECU-8 using supplied looms and short length of steel conduit (25 mm OD, max. length 60 mm).
After mounting, remove any dust/swarf and re-install base PCBs. Ensure all connecting looms are refitted.
