1.4 Installation.
1.4.1 Siting Requirements.
•Avoid locations that expose the equipment or cabling to
excess heat, dust, humidity and especially damp or
condensation; e.g. do not install any parts in bathrooms.
•Avoid locations close to other electrical equipment such as
motors or switch gear. Do not install extension sockets within
50mm of a.c. mains sockets. Do not run extension cables
close to mains electrical cables.
•Remember when selecting the location of the first extension
socket box (EX2), that this is the only phone that will work
during a power failure.
The cable lengths between the various parts of Sapphire are:
Distribution: to mains power socket = 1.2m
Box to exchange line socket = 3m
to Master Terminal = 3m
to extension sockets = 200m (maximum)
1.4.2 Cable Routing.
Besides the siting requirements opposite, remember the following:
•Choose a route for each cable that is safe from damage
by feet, doors or other hazards.
•Use cable clips to secure the cable at a minimum of
300mm intervals.
•Do not run the extension cables closer than 50mm to
mains power supply cables.
•Allow sufficient spare cable (200mm) at either end for
final connection and for reconnecting if necessary.
•A separate cable must be used for each extension.
Multicore cable must not be used.
1.4.3 Master Jack Sockets.
The extension Master Jack socket must be mounted vertically on
a wall surface. For each extension:
1. Remove the cover from the Master socket box by releasing the
two retaining screws.
2. Choose and breakout a cable entry point for the extension cable.
3. If necessary mark, drill and plug two fixing screw holes in the
wall.
4. Screw the socket box to the wall and feed in the extension cable.
5. Remove approximately 50mm of cable sheath. If the socket
has screw terminals bare 5mm of the wire ends.
6. Connect one wire to terminal 2 and the other wire to terminal 5
of the socket. If the socket uses IDC slot connectors use the
proper wire insertion tool. Do not use any other edge to insert
the wires as this will damage the terminal slot.
7. Secure the cable using the cable clamp.
8. Replace the socket box cover.

TECHNICAL NOTICES
Sapphire is approved for connection to telecommunication sys-
tems operated by British Telecommunications plc, Kingston Com-
munications or Mercury Telecommunications Limited., subject to
the following conditions.
1. The Sapphire Telephone System is suitable for connection to Exchange
lines which provide Loop Disconnect (LD) or Multi-Frequency (MF) signal-
ling. Sapphire is connected to the exchange line by means of an attached
cord fitted with a jack plug that complies with BS6312 (1+5 systems) or will
be hardwired (2+8 systems).
2. Only telephones which have been approved to BS 6317 (1982) may be
connected to Sapphire (these always carry the circular green approval la-
bel). Sapphire must be used with Timed Break Recall (TBR).
3. Interconnection directly or by way of any other apparatus, of ports marked
in accordance with BS 6301 paragraph 4.3.1(a) with ports not so marked,
may produce hazardous conditions on the BT network. Advice should be
sought from a competent engineer before such a connection is made.
4. The Sapphire system is designed to operate with a mains supply of 240V
ac. 47-63Hz with a maximum power consumption of 20W.
5. The system is not suitable for use as an extension to a payphone.
6. Wiring from the Sapphire Distribution Box to the extensions must be con-
fined to the same premises. The extension cable must not exceed the
length of 200 metres and a loop resistance of 34 ohms. A separate cable
must be used for each extension, multi-core cables must not be used.
7. Where installations include the use of external exposed cabling, protec-
tion against induced over-voltages must be provide by gas discharge tubes
(Protectors type 14A or 15A), mounted in suitable housings and located be-
tween each exterior extension or exchange line and Sapphire. Only the local
telephone authority may install this equipment.
8. It is permitted to connect Sapphire as a satellite to a PBX (Private Branch
Exchange). However, satisfactory performance cannot be guaranteed with
every possible combination of host and subsidary system.
9. The Sapphire has a Ringer Equivalence Number (REN) of 1 and the ex-
tension port has a REN of 2. REN is a number which is assigned to items of
telephone equipment, in order to prevent telephones overloading the line
and causing misoperation of the ringers. The maximum REN value con-
nected to an exchange line is 4.
10. Refer all servicing to qualified personnel or to the Customer Servicing
Department at the address given on the back of this handbook.
11. The line cord and mains cable must be disconnected before remov-
ing the cover of the Sapphire Distribution Box.
12. The Sapphire System must be installed and operated in an environment
within the following specific limitations:
Temperature:Operating
–
0°C to 40°C Humidity: <95°
Range Storage
–
20°C to 70°C (Relative)

1.4.4 The Distribution Box.
Mount the Sapphire Distribution Box on a wall, as shown below.
Allow a clearance of 75mm between the base of the box and any
surface below. The diagram below also shows the spacing for the
fixing holes.
Caution: Electronic parts in the Distribution Box may
be damaged by static electricity discharges. Do not
touch any of the electronic circuitry during installation.
1. Remove the Distribution Box cover by releasing the retaining
screw. Only remove the cover when absolutely necessary.
2. Mark on the wall the centre positions of the two fixing holes
(Use the guide shown opposite). Drill and plug the holes using
the two plugs provided.
3. Screw in the right-hand roundhead screw until the screw head
is within 2mm of the wall.
4. Place the Distribution Box over the right-hand screw so that the
key hole slot engages with the screw. Adjust the screw to hold
the Distribution box firmly against the wall.
5. Insert and screw in the left-hand screw.
6. Fit a 13-amp plug with a 3-Amp fuse to the mains cable. Con-
nect the mains cable wires as follows:
– Blue to the pin marked N, Neutral or Black
– Brown to the pin marked L, Live or Red.
7. Do not connect the mains supply or exchange line at
this time.
1.4.5 Extension Cable to Distribution Box Connection.
The diagram below shows how the extension cables connect into
the distribution box.
1. Unscrew the retaining screws from the extension cable clamp
and remove the clamp.
2. Feed the first extension cable through the upper end of the ca-
ble slot.
3. Remove approximately 15mm of the cable sheath.
4. Bare 5mm of the wire ends.
5. Using a small screwdriver, attach the wires to the first pair of
screw terminals (EX2).
Warning:The extension connected to EX2, the upper
pair of terminals, is the Power Fail Phone extension
and must always be connected.
Repeat above steps for the remaining cables, attaching them to
remaining pairs of screw terminals; EX3, EX4 and EX5.
7. Replace the cable clamp. Ensure that the cable sheaths are un-
der the clamp before tightening the clamp screws.
8. Replace the top cover of the Distribution Box and screw in the
cover retaining screw.
1.4.6 Master Terminal Connection.
The Master Terminal connects to the Distribution Box using a D-
type plug. Finger tighten the plug retaining screws.
1.5 Checking the System.
Use the following sequence to check the Sapphire installation.
If the Sapphire fails one of the tests; switch Off the mains
power, unplug the exchange line and then check the Sap-
phire wiring.
1. Test all the extension phones by plugging each of them directly
into the exchange line socket and making a call.
2. Check that there are no wiring mistakes and plug all extension
phones into their sockets.
3. Plug in the Distribution Box mains lead and switch the power
On. Do not plug in the exchange line socket at this time.
4. Make an internal call from one extension to another. Check that
the ringer works correctly and that the speech is clear and
noise-free.
5. Repeat the above step for each extension.
6. Switch Off the Distribution box power and then plug the ex-
change line lead into its socket.
7. Check that the phone in the Power Fail socket (extension 2(1+5)
or 12(2+8)) is working by making an outside call.
8. Switch the mains power On again.
9. Make an external call from each extension by dialling [9].
10. Please note; in default the external line type is set to LD (see
1.5 on Sheet 3, Programming).
