SigTEL EVCS Typical Wiring Overview

Install the EVCS

Location

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

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.

Wiring and Cable Entry

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

aximum recommended cable distance to the outstations is 1 km, beyond which audio quality may degrade. For wiring and connection details

refer to Type A outstation instructions (Doc. No. DC 0003819) 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.

Before commissioning the system ensure that all equipment is fully installed, connected and wiring tested. Check all

handsets are on-hook and no calls or faults are present on the system. The ECU-4/ECU-8 shows ‘System Healthy’ status

Naming Extensions

Select ‘Edit Phonebook’ option.

ACCEPT - moves to next character

END - moves to previous character & exits

DIRECTORY - saves changes

At the ECU-4/ECU-8, with the handset on-hook, select the ‘Edit Phonebook’ option by following the flow chart below. With an operator at the

ECU-4/ECU-8, go to each outstation in turn and make a call. At the ECU-4/ECU-8 lift the handset and press the ACCEPT button. The outstation’s channel

is opened for speech and automatically selected for editing. Check audio quality of the line and inform the operator at the ECU-4/ECU-8 your position.

They can edit the outstation name directly (see Naming Extensions below). Repeat this process for all remaining outstations but to avoid confusion only

call in from one outstation at a time. Outstations can also be manually named if you are sure of its location.
