3-1. UNPACKING.
After unpacking the Model 300MB, examine
it for damage that may have occurred in transit. If
the equipment has been damaged, do not attempt to
install or operate it, file a claim immediately with the
carrier stating the extent of the damage. Carefully
check all envelopes, shipping labels and tags before
removing or destroying them. Before attempting to
install the CommCenter, be sure that all parts listed
in the KIT CONTENTS LIST have been supplied.

3-3. INPUT CONFIGURATION.
The CommCenter can be configured for remote
activation in four ways:
• Normallyopenlatchingcontacts.
• Normallyopenmomentarycontacts.
• Normallyclosedlatchingcontacts.
• Normallyclosedmomentarycontacts.
The unit is factory set to be activated by clos-
ing a normally open latching contact between the
associated input and circuit ground. When activated
the message will continue to loop and repeat. It will
stop as soon as it is deactivated. When configured for
momentary activation, the message will continue to
loop and repeat until the input is deactivated. Upon
deactivation of the input, it will play the entire mes-
sage before stopping.
Each of the six inputs can be individually con-
figured by moving a two position jumper on a three
position header. See table 3-1 for a list of the Priority
Tones, their associated jumper designation and their
marking as shown on the printed circuit board silk-
screen.
3-4. CONTROL CIRCUITRY.
A. The control circuitry in the CommCenter
has a built-in priority level feature. If a given mes-
sage is already sounding when a higher priority
message is activated, the higher priority message
automatically overrides the lower priority message.
When the higher priority message is deactivated, the
lower priority message is initiated as long as it is still
activated. The messages are prioritized with Priority
Tone 1 having the highest priority down to Prior-
ity Tone 6. The cascade input has the lowest level of
priority.
Failure to follow all safety precautions and
instructions may result in property damage,
serious injury, or death to you or others.
