same time with the panel microphone gain set to maximum, feedback
may occur even if the speaker mute (see the “Speaker Mute” section,
next) is set to maximum. In this case, it will be necessary to turn the
panel microphone gain down. Similarly, in some noisy environments it
may be necessary to turn the panel microphone gain down and have
the operator talk more closely into the microphone.
To adjust the panel microphone gain:
1. Remove the panel cover.
2. Use a small screwdriver to adjust the control marked “P1” on the
Main PCB. See Figure 10.
3. Reinstall the panel’s cover.
SPEAKER MUTE
When a panel microphone and a speaker are used together, feedback
is possible. To reduce this possibility, the panel software will mute (turn
down) the speaker level by some predetermined amount when both
the microphone and speaker are enabled. The speaker mute can be
adjusted from 0 to 15 dB; its default setting is 6 dB.
Refer to the Eclipse Configuration System Instruction Manual for
instructions on muting the speaker.
PAGE VOLUME LEVEL
When Page Override is assigned to a label, the audio level at the
destination panel(s) is predetermined. This function allows talking to
someone even if his panel’s volume control is off. Two things will
happen when a panel activates such a label:
• If the destination speaker was off, it will turn on.
• The panel’s speaker output will be at the predetermined level
regardless of the “Intercom” volume control setting, unless this
control is set higher than the predetermined level.
The page volume level can be adjusted within a range of 0 to 10,
equivalent to the front-panel control settings of 0 equals off and 10
equals full pot. The page volume level’s default setting is 5.
Refer to the Eclipse Configuration System Instruction Manual for
instructions on using Page Override.
PANEL-TO-MATRIX CARD BAUD RATE
The RS-422 serial data communication between a panel and other
devices can operate at standard (19.2 k baud, the default) and
long-line (9600 baud) baud rates. Use long-line only if encountering
problems with the standard baud rate.
The baud rate is set from the configuration program and the panel
automatically adapts.
