CS106 Combined Door Entry and Coded Access
35
Installation of the Door Entryphone System
From an electrical point of view, the combined systems may be regarded as
separate door entry and coded access systems with the exception of a common
lock release. The coded access system and its installation is described in detail
in the preceding half of this manual. The wiring diagram on page 42 shows the
wiring connections for the Door Entry Telephone System, including the simple
connections which interface with the C106 Coded Access Controller.
The Model 801 Door Entry Telephone
This is designed to be wall mounted in a convenient indoor location.
The Entrance Panel
The entrance panel, containing the speech unit, is supplied with either a surface
or flush-mounting back box. It should be mounted on an outside wall near the
front door, and in a sheltered location.
Extension Phones
Each apartment can have upto 3 extension phones (4 phones in total).
Tradesman button (optional)
This is used in conjunction with a time-clock to allow tradesmen access during
restricted hours. The time-clock may be 240V AC or 12V DC operated, but must
have a voltage-free isolated contact.
