Display Control Keypad (Model 8345)
The Display Control Keypad (see Figure l-2) is the
primary way of communicating with the CCU, and
at least one of them is required for every system.
Up to 8 keypads (maximum of 5 of them Display
type) may be used in a single system (maximum of
4 for UL Listed systems). The dealer/installer can
completely program the System 8300 through the
Display Control Keypad; the user can perform the
User-Level programming operations with it.
Figure 1-2 Display Control Keypad
In addition to the status-indicating LED’s, the
Display Control Keypad has a Liquid Crystal
Display (LCD) which provides specific status
information, visual feedback, and guidance during
programming. Audible feedback, error tones,
chimes, alert tones, and phone/intercom audio are
provided by the built-in audio system; unnecessary
sounds can be silenced with the Volume control on
the case. Pushbuttons provide programming,
alarm entry, and protection level setting. Built-in
backlighting makes the it possible to read the
display and see the pushbuttons in total darkness.
The Display Control Keypads can be used as
Listen-In devices to allow the monitoring service
to listen following an alarm report.
NOTE:
This service may not be provided by all Monitor-
ing Services.
Control Keypad (Model 8340)
The Control Keypad (see Figure l-3) is similar to
the Display Control Keypad in that it accepts
Access Codes and allows the user to change the
system’s level of protection (unless the need for
bypassing complicates the issue). In addition it
provides audible and LED alarm information. But it
does not display written information, or give the
ability to program the system (beyond the OFF,
DAY, NIGHT, and AWAY levels of protection), and
doesn’t have phone or intercom capability. Since
it may be used in places where unnecessary
sounds from the system are not desired, there is a
switch provided on the Control Keypad which will
turn off audible signals other than alarms), so the
keypad may be used in areas where such sounds
would be distracting or offensive (baby’s room in
a home, an office or sales area in a commercial
installation).
