push button for each telephone, a speaker grill and an integral keypad,
which is similar in style to the Model 216 keypad.

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. Diagram 4 shows
the wiring connections for the Door Entry Telephone System, including the
simple connections which interface with the CK108+ Coded Access
Controller.

chapters and ensure the section ‘Important Safety Information’ is read.
The Model 500D 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.
Tradesman button (optional)
This is used in conjunction with a time-clock to allow tradesmen access
during restricted hours. The time-clock should be 240V AC operated with
a voltage-free isolated contact. It should be mounted adjacent to the Power
Supply. Please read ‘Important Safety Information’.
