Step 6: Replacing Cards in the CP-220A
a) When inserting a card, carefully guide it into the
designated slot, being sure that its electronic
components are facing
toward the left.
Once the card
reaches the edge connector, push it firmly until it snaps
into place.
b)
Reinstall the CP-220A's front panel and top cover at this
time by reversing the sequence covered earlier in Step 1.
The Front Panel of the
CP-220A
The front panel of the CP-220A contains all of the controls
and features necessary for an operator at the Central
Station to use the Receiver and interpret the information it
produces.
FIGURE 1-5
The front panel of the CP-220A provides a
display that produces all the necessary
information needed by an operator to
process alarm, trouble, and supervisory
messages received from the Central
Station's subscribers. To its right is a keypad
that is used primarily to program the
CP-220A with an operating configuration
desired by the Central Station. On the left
side of the unit, a loudspeaker, a volume
control, and a headphone jack provide the
operator with the ability to "listen in" to the
activities surrounding the conditions that
have caused alarms from designated
subscribers. Finally, a series of 8 indicators
(LEDs) correspond to the activities of up to 8
Line Cards placed in the receiver. See the
text for additional details.
Fluorescent Display
Prominent on the face of the CP-220A is a 40-character
fluorescent display, which, among its other attributes,
furnishes information about alarms and other messages sent
by the subscribers to the Central Station. The display also
provides date and time information and assists in the
programming of the receiver.
Front Panel Keyboard
An 18-key keyboard is located at the right side of the
receiver. Its primary purpose is to perform the programming
operations that configure the CP-220A for the requirements
of your Central Station.
