Installation (Telephone sockets)

Product performance,
systems compatibility

Master Sockets: for use as the first socket
outlet on a direct exchange or PABX line. They
contain surge protectors (for line protection
against electrical surges) and capacitors.

Secondary Sockets: For use as extension
sockets when connected on the same master
line as a Master Socket.

Wiring regulation restrictions

Domestic installations: Any number of MK
sockets may be installed thereafter, with a
maximum of 5 telephones normally being
allowed on one exchange line.

Industrial and commercial installations: MK
telephone sockets are suitable in all situations
after the PBX/PABX has been installed by a
recognised installer. For key systems and other
‘special’ systems, the manufacturer’s instruc­tions should be referred to.

Installation tools required

MK IDC insertion tool List No. 400 or 22630
(not supplied with product).

Cable Management

Logic Plus Telephone and TV sockets can be mounted in a
variety of MK trunking systems.

See MK catalogue for further details.

Installation (TV sockets)

Product performance,
systems compatibility

Non-isolated products are intended for direct
connection to a single or two separate TV/FM
aerial downleads: These units must NOT be
used in multi-outlet aerial distribution systems.

Isolated products are intended for such use
and provide the necessary safety isolation,
rated at 2000V AC, against a fault occurring
within any mains powered product used
elsewhere in the system (it is intended that
each unit be fed from a separate ‘T’ box con­taining electrical padding and attenuation).

Method of installation of TV and FM aerial
connection by using MK co-axial socket outlet
and only one down lead.

1. Connect co-axial plugs to the ends of TV

aerial and FM aerial cables in loft.

2. Plug into frontplate of co-axial socket

outlet situated in loft.

3. Run a length of co-axial cable from back of

this outlet to the back of the outlet
situated in the living room, then plug TV or
FM radio into frontplate as normal. This is
a very simple neat solution which works
well technically.

Use of cable clamp

Sharp bends in the cable must be avoided
during installation. The single TV/FM socket is
fitted with a cable clamp that can be fixed on
either side of the termination position to
facilitate this.

Safety information

None of the above products should be
installed into the same fixing or mounting
boxes as mains rated cable.
