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 wooden frame door fitted
with a surface or mortice lock. This should be installed with a small amount of play on the door as operation
will be impaired if too tight.
This is used in conjunction with a time-clock to allow tradesmen access
during restricted hours.
For optimum speech clarity, it is strongly recommended that this system is installed
using twisted-pair telephone cable (eg type CW1308). Use one of the pairs for the R & O connections
between the speech unit and the telephone.
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:
VolumeA: Speech level at the Entrance Panel
Volume B: Speech level at theTelephone
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.
