Installation & Operational Guide

Special Note

The adhesive quick reference labels included with the Opera 104 system are intended as aids for use in conjunction with MF (tone) dial telephones with real time break recall only. Do not employ them when using non-MF dialling telephones. Where ‘R’ appears on the labels, a decadic ‘1’ will perform the same function.


Warning

This system is subject to legislation covering systems connected to the telephone network.


For this reason, and for your safety, please read this manual carefully before installing the OPERA 104 system.

1. System Description
1.1 Introduction

The OPERA 104 operates as an advanced local exchange, or PABX, for four telephones and a single exchange line and provides features and facilities only found on much bigger systems.


1.2 Description

The OPERA 104 enables the four extensions to share the exchange line in an ordered and intelligent manner. Its basic facilities are as follows:




  • Any extension can access the exchange line and make a call.

  • Any extension can make an internal call to any other extension.

  • An incoming call rings at all free extensions and can be picked up at any extension.

  • While on an external call, as an extension can put the call on hold and make a private enquiry call.

It can then transfer the external call to the second extension or return to the external call in private.



2. Installation Instructions
2.1 Warning


  1. Please read this section in details before installing the OPERA 104 and adhere to the instructions

  2. The OPERA 104 is approved for connection to BT PSTN exchange lines with DTMF or LD signalling via the exchange line master socket.

No attempt should be made to connect to it other than using the modular plug provided.

If there is no exchange line master socket available on the premises then one must be fitted by British Telecom, Mercury Communications Limited or Kingston-upon-Hull Telephone Department.



  1. Removal of the access cover is all that is required to access the extension terminals during installation.

  2. Do not remove the three sealed screws on the base of the OPERA 104 as this invalidates the warranty and could expose you to dangerous voltages by removal of the top cover.

There are no user serviceable parts in the OPERA 104 other than fuse replacement which is located in the mains plug.

  1. Do not connect the OPERA 104 into the exchange line or the mains supply until stated in the installation procedure.

  2. Avoid mounting the OPERA 104 or the extension sockets on damp walls or in areas exposed to damp or condensation. Maintain at least 50mm clearance from main electrical outlets in all cases.

  3. Use approved cable for all extension wiring and fix all installation wiring every 300m.


2.2 Installation Procedure
The following is a step-by-step guide to the OPERA 104 installation.
Step 1 Decide on a location to wall mount the OPERA 104.

  • The location should have good ventilation and, where possible, be

secured against unauthorised access to the OPERA 104.

  • The location should be free from damp or condensation. Avoid installing the system in areas plumbed for water, kitchens, bathrooms etc.

  • A mains power socket should be provided within two metres of the OPERA 104.

Step 2 Wall mount the OPERA 104.



  • Loosen the access cover screw and lift off the access cover.

  • Position the OPERA 104 template on the wall and mark the positions of the three retaining screws. Use three No. 8 screws provided.

  • Drill holes for retaining screws and insert screw in positions 1. Hang the unit on the wall.

  • Secure the Opera 104 by inserting the remaining screws on either side within the access area (positions 2 and 3).

Step 3 Plan the extension telephone wiring



  • For each extension telephone, a master line jack is required into which you plug the telephone.

  • To connect the line jack to the OPERA 104, an appropriate length of two-wire cable is required. Use approved cable.

As there are restrictions on the maximum length of his cable to guarantee correct telephone operation, never exceed 46 Ohms which is equivalent to 250m of 0.5mm copper wire.

  • Never route extension wiring outside the premises as this could expose the OPERA 104 to hazardous voltages such as lightning.

  • If less than four extensions are being installed then always install Extension 2 first and then, subsequently, Extensions 3 and then 4.

Step 4 Install the extensions for each extension telephone



  • Wall mount the extension telephone Master socket.

  • Prepare the two wires of the cable and connect to the master socket.

  • Route the extension cable to the OPERA 104 system observing good building wiring practice by maintaining at least 50mm clearance between the extension cable and mains power, exchange line or other building cable.

  • Prepare the cable and connect the two wires to the appropriate two extension terminals on the OPERA 104.

The four pairs of extension terminals are located in the access area and marked in groups of two and Ext2, Ext3, Ext4, Ext5.
Step 5 Install the exchange line

  • Route the supplied exchange cable from the OPERA 104 to the exchange line connection point.

Step 6 Test the PABX power fail operation



  • Replace the access cover and secure the access cover screw.

  • Connect the OPERA 104 exchange line into the exchange line socket.

  • Plug a telephone into the Ext2 socket.

  • Make a local call from Ext2 and check for normal operation.

  • Arrange for someone to ring you and check for normal operation.

Step 7 Test the PABX with mains power



  • Plug telephones into all extension sockets.

  • Plug the OPERA 104 into the mains socket.

  • Lift each telephone handset in turn and check for continuous dial tone.

  • Make a call to each extension by dialling the extension number from another telephone and check that the telephone rings, i.e. to ring Ext3, dial 3 from any telephone.

  • Have the calls answered and check speech path.

  • From each extension in turn dial ‘9’. Wait for exchange dial tone and make a local call.

  • Arrange for an incoming call and check that it rings at each free extension telephone.

Pick up the handset at a ringing telephone and check that you receive the incoming call.

Note: It is possible to connect a combination of DTMF and loop disconnect

telephones to the OPERA 104 when operating out of a digital

telephone exchange which accepts both loop disconnect and

multi-frequency signalling. Please note however that the OPERA 104 learns the type of signalling used at each extension. It is therefore necessary to power down the OPERA 104 when changing the type of telephone used at any extension.



3. Operation Guide
This section details the operation of the OPERA 104.
3.1 Power Fail Operation

In the even of a mains power failure, the OPERA 104 will allow normal operation of the Ext2 telephone only.

Fit a 3amp approved fuse in the plug.


REN (Ring Equivalence Number)

The REN of a BT line is 4 which means that a maximum of four telephones of apparatus with a REN of 1 could be connected in parallel.


The REN of the OPERA 104 exchange port is 1 which means that 3 telephones of REN 1 could be connected in parallel.
The OPERA 104 extension ports have a total REN of 1 which means that only telephones with a REN of 1 or less should be connected to the extensions.
WARNING
If a telephone is connected in parallel with the OPERA 104 exchange line, then:

‘During dialling, the OPERA 104 may tinkle the bells in the other telephones sharing the same line. This is not a fault and we advise you not to call the Fault Repair Service.’
