DESCRIPTION
Our Model DP3 Flush Mount Door Phone is specifically designed for
connection to a Telephone Technical Services DOOR STATION
CONTROLLER. It can be FLUSH MOUNTED or SURFACE MOUNTED if
the optional SMK3-V or SMK3-H Surface Mount Kit is used (see p14).
Up to two of our Door Phones can be connected to the one DOOR
STATION (CONTROLLER). This allows for a Door Phone to be located
at two different locations. In this situation, the Door Phone devices are
connected in parallel (see wiring directions page 13).
DP3 is available with a 316 Marine Grade Stainless Steel fascia plate,
which has been coated with a tough transparent protective polymer
material, or with a Brushed Aluminium front fascia plate.
Our DP3 units incorporate a ‘touch sensitive’ switch, in order to further
improve it’s long term reliability. This switch is activated by a brief touch.
All DP3 units are designed to be highly WEATHER RESISTANT and they
have proven to be reliable over long periods of time, providing they are not
exposed to direct rain. Whenever your Door Phone is likely to be
exposed to RAIN, an optional DOOR PHONE COVER or a SURFACE
MOUNTING KIT with Rain Deflector should be used (see pages 14-15)
All DP3 models can be mounted either horizontally or vertically but for
aesthetic reasons, they are also available with the BELL of the Touch
Sensitive trigger area orientated in a Horizontal or V ertical Orient ation.
There are 4 Models of DP3 :
DP3-AV Aluminium Fascia - Vertical Orientation
DP3-AH Aluminium Fascia - Horizontal Orientation
DP3-SV Stainless Fascia - Vertical Orientation
DP3-AH Stainless Fascia - Vertical Orientation
DP3 incorporates a 10mm (Aluminium Fascia) or 12mm (Stainless S teel
Fascia) hole which is sealed with strong transparent perspex plate which
will allow you to fit a Digital Camera behind the Door Phone plate. T wo
threaded mounting studs are provided for this purpose.
We alternatively offer a Model DP4 Door Phone which is the same as
DP3, but includes an integrated, Low Light, High Resolution Digital
Colour Camera, in a sealed plastic enclosure (see page 5).
