Loudspeaker
At the lower left of the front panel is a loudspeaker, which is
used with the CP-220A's
Listen-In
capabilities. Individual
subscriber accounts may take advantage of the
Listen-In
feature, in which the audible activities and conversations
surrounding alarm conditions from such subscribers can be
heard, recorded, and evaluated.
Listen-In
is particularly well
suited to Medical Emergencies, but can be used in
conjunction with virtually all types of alarms.
NOTE: Detailed information on the CP-220A's
Listen-In
functions can be found in
Section 2,
beginning on
page 2-34.
Headphone Jack
For private listening, the
Headphone Jack
will accept a
standard ¼ inch monophonic plug to which an 8-ohm
monaural headset is connected. When used, the headset will
silence the loudspeaker.
If necessary, stereo headsets (like those used with
Walkman®
-type products) that have 3.5mm-diameter stereo
mini-plugs (see "A" at the left) can be accommodated to
operate with the CP-220A by following the steps below:
1. For best performance with the CP-220A, the stereo
headphones you obtain should have an
impedance
as
close to 8 as possible.
2. Purchase an adapter that converts the headphone's
3.5mm stereo mini-plug to a ¼" monophonic plug (see "B"
at the left).
NOTE: An adapter manufactured by International
Components Corporation (Model
35-160) or its
equivalent will be suitable for this purpose. If
desired, call (800) 645-9154 or (516) 293-1500 for a
list of ICC distributors.
Volume Control
The Volume Control adjusts the volume level of the speaker
or, if used, the headset. It also affects the output level
obtained from the "Listen-In Audio" terminals on the rear of
the receiver (see Figure 1-6).
LED Indicators
Eight LED (Light-Emitting Diode) indicators are provided to
represent each of the 8 possible Line Cards that the
CP-220A is capable of using. Each LED, when lit, indicates
that there is activity on the corresponding Line Card. Under
typical conditions, it is normal for an LED to flash on and off
when processing data.
