Call Drop Flash
This feature helps to inform you who has recently
called. In a fast-paced environment, you will receive
a quick messages from other Intercom users. The cor-
responding
Listen
indicator will continue to flash even
after the caller has dropped the call. The default drop
flash time of 5 seconds will give you a chance to glance
at the IP Intercom panel and easily determine who has
recently called.
Trigger Level
This setting is communicated to all other IP-Inter-
com stations. It controls the priority of this IP-Intercom
station when it is calling another IP-Intercom station.
When any IP-Intercom station listens to multiple sources
simultaneously, those with lower “trigger level” will be
muted or dimmed by another IP-Intercom user with a
higher priority.
The possible settings for Trigger Level are:
1. IFB
2. Low Priority (Mute IFB)
3. Low Priority (Dim lower priority sources, Mute
IFB)
4. Default (Dim lower priority sources; Mute IFB)
5. Above Normal (Dim lower priority, Mute Low
Priority and IFB)
6. Above Normal (Dim low priority, Mute Low Pri-
ority and IFB)
7. High (Mute lower
priority sources)
8. Highest (Mute low-
er priority sources)
Dimming and mut-
ing of external sources
is configured on the
Ext Sources page (de-
scribed in the next sec-
tion).
Dim Level
This setting speci-
fies the degree of dim-
ming. It is variable
from 0 (no dimming)
to full mute. Any Dim
Level greater than 99
dB is considered to be
equivalent to MUTE
and the * symbol will
be displayed.
