Installation of Door Entry Systems
The
is designed to be wall-mounted in a convenient indoor location.
The
, containing the speech unit, is available with either a surface or flush-mounting back box.
Normally this would be mounted on an outside wall near the front door, and if possible in a sheltered location.
The
is designed for use on an inward opening door fitted with a surface
night-latch type lock. This should be installed with a small amount of play on the door as operation will be impaired if too
tight.
For optimum speech clarity, it is strongly recommended that this system is installed using
twisted-pair telephone cable (eg type CW1308 or CAT5e). Use one of the pairs for the R & O connections between the
speech unit and the telephone.
For cable distances greater than 50m or for other lock releases contact Technical Support.
Connect all items by following the diagram overleaf. It is strongly recommended that a single telephone
be connected at a time and fully tested before proceeding to the next.
The speech unit has two controls at the rear for adjustment of speech levels:
Volume A:
Speech level at the Entrance Panel
Volume B:
Speech level at the Telephone
If feedback is experienced (a howl or whistle) turn both controls to 'off' and then slowly adjust each up in turn until a
satisfactory level of speech is attained.
No speech/ insufficient speech: Initially establish correct operation of the Speech Unit by
disconnecting all telephones and re-connecting a single telephone with a short length of cable (R O T only); Reconnect
the telephones one at a time until the fault re-appears. Note: speech will be impaired if one or more telephones are left
off the hook.

electrical cupboard, close to a 230V AC electrical supply. It must be wall-mounted onto
plasterboard, wood or a similar non-conductive material.
Connections to the 230V AC mains supply must be carried out by a qualified electrician or
similar competent person, and made in accordance with accepted safety practices. A two-
pole switch ( as provided by a Consumer Unit or Switch-Fuse) must be included to isolate
both Live and Neutral during Installation or Maintenance . The transformer is protected by
fuses; always replace these with the correct type and rating.
Use only mains cable to BS6004 or equivalent, within the following specified limits:
