4" Color Touch Panels with Audio
Light Sensor
The CP4/A is equipped with a photo-sensitive sensor that gives the panel the ability to
automatically switch the brightness of the display’s backlight between two settings: Normal Room
(NRM) and Dim-Room (DRM). The panel’s backlight is the amount of light emanating from the
buttons and LCD display.
Normal-Room mode
is equal to the brightness of the backlight directly selectable from
the
SET BRIGHTNESS
button in the Setup page.
Dim-Room mode
allows the user to directly select the brightness value of the backlight
from the Sensors Setup page >
ADJUST SENSORS
button.
Passive Infrared Sensor
The on-board infrared sensor provides motion detection that either "wakes-up" the CP4/A (Infrared
Wake) or sends an I/O signal to the Central Controller (Infrared Push/Release). This sensor is
mostly used for the illumination/non-illumination of the LCD, external backlit pushbuttons, and use
in the Push/Release control of room lights. The Adjust Sensors page displays a level indicator and
buttons that allow the user to change the following PIR settings: Infrared Wake, Infrared Push/
Release, Activation threshold.
IR Receiver
The CP4/A is equipped with an on-board IR receiver that is capable of receiving a one-way 38 KHz
signals (of AMX codes only). The properties for this receiver is capable of being set through
the
Using the Adjust Sensors Setup Page
section on page 34. The maximum range is 15 feet
(4.57 m) for the AXT and 22 feet (6.71 m) for the AXD unit. Reception angles vary dependant
upon the elevation and location of the installed panel.
Audio Tones
The CP4/A is equipped with a transducer that gives the panel the ability to both produce six
different audible tones and deliver sounds from other connected CP4/A panels. The tones are
enabled through the use of the
BEEP
AXlink Send_Command. Refer to the
BEEP n s
section on
page 45 for more detailed information about the tones and their specifications.
Speaker Volume
The speaker volume can be set through either the Speaker Volume section of the
Using the Adjust
Sensors Setup Page
section on page 34 or via the use of commands such as
SVOL
AXlink
Send_Command. Refer to the
Using the Audio and IR Device Setup page
section on page 37.
Microphone
The on-board microphone provides a user with the ability to transmit audio from one CP4/A touch
panel to another connected panel on a system. Refer to the
Wiring the Touch Panel
section on
page 21 for more information on panel wiring diagrams. These transmitted signals can be
configured to transmit to either specific panels or all panels on a system. The microphone volume
can be set through either the Microphone Adjustment section of the
