SigTEL EVCS Wiring Overview
Install the EVCS
Location
Site all equipment indoors in well-lit areas, free from obstruction. If background noise exceeds 40 dB, use
an acoustic hood. Site control unit(s) in the control room or lobby, 1.4 metre 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
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-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
correctly; ECU-8 internal connections are B to B, C to C. ECU-8 to ECU-8S (optional) is A to A, D to B.

Wiring and Cable Entry
See Fig 1 above for cable types. Install all wiring in accordance with the current edition of the IEE Wiring Regs (BS 7671), or relevant national
standards. Use enhanced fire-rated cables between outstations and control equipment.
Test Outstation Lines
Test all lines for faults before terminating outstation lines to the ECU-8/ECU-8S. In addition, test outstation lines using a FITT telephone line
tester (see component list above).
CAUTION: DO NOT use an Insulation Resistance Tester (Megger) with any devices connected as they will be destroyed.
Fit Outstations
See Fig 1 above for cable type. Maximum recommended cable distance is 1 km, beyond which audio quality may degrade. For wiring and
connection details refer to Type A outstation instructions (Doc. No. DAU0000001) and Type B outstation instructions (Doc. No. DAU0302000).
Connect Outstation Lines to the Control Equipment
Do not connect outstation lines to the ECU-8, or optional ECU-8S, until they have been tested, fault-free and suitable cable glands fitted.
Connect outstation lines directly to the Exchange PCB (see Fig 2 left). Connect screens to the earth terminal in the back of the enclosure.
