The default configuration for both Mode 1
and Mode 2 is On When Call Active. Note
that the exact action of the visual indicator
when it’s active will follow the Intensity,
Action, and Color configuration param-
eters, described next in this guide.
The Always On configuration can be
useful for a number of purposes. One
example is to make it easier to observe
the action of the visual indicator as its
intensity, action, and color configurations
are selected. “Forcing” the visual indica-
tor to be active simulates what will occur
when a call signal is active. This configura-
tion choice also allows the visual indicator
to serve as a general-purpose, local, or
remotely-controlled indicator or “beacon.”
Informing users about a “closed set” or
“rehearsal in progress” situation could be
easily accomplished.
Minimum On Time
Choices are: Follow Call, 2 Seconds,
4 Seconds, and 6 Seconds
The Minimum On Time configuration can
be useful in situations where it’s important
for users to be aware that a call signal has
been received. In the Follow Call configu-
ration the on/off status of the visual indica-
tor will directly respond to an incoming
call signal. So, as an example, a very short
(e.g., less than one second) call signal will
result in a very short “burst” of light from
the visual indicator. The Follow Call setting
is the default for both Mode 1 and Mode 2.
It might be the correct setting for some ap-
plications, but may allow situations where
users can be unaware that call activity
took place.
The configuration choices for two, four, or
six seconds ensures that the visual indi-
cator will light for a “reasonable” amount
of time. Selecting one of these values will
ensure that the visual indicator will acti-
vate for a minimum period of time. As an
example, if set for four seconds and a call
signal is received for three seconds, the
visual indicator will stay active for an extra
one second. (It would stay enabled for four
seconds.) Should, in this same example,
the call signal remain active for five sec-
onds the visual indicator will immediately
turn off at the end of the five seconds. (The
five second call signal would exceed the
four second minimum on time.)
Technically, the three minimum time
choices could be considered to provide
non-retriggerable one-shot actions. This
is effectively a logical “OR” function with
the call signal and either a two, four, or six
second timer serving as the inputs. The
call signal also serves as the timer start trig-
ger. (But ignore this description if you’re a)
not an engineer and/or b) don’t appreciate
this kind of obscure technical stuff!)
Intensity
Choices are: Low, Medium, and High
The brightness (amount of lumens) emit-
ted by the visual indicator can be selected
using the Intensity configuration. Select the
value that’s appropriate for the application.
The default intensity value for both Mode 1
and Mode 2 is High.
Action
Choices are: Continuous, Slow Flash,
Fast Flash, and Pulse
The four Action choices allow the character
of the visual indicator to be selected. Select
the configuration that best fits the applica-
tion. When selected for Continuous the
visual indicators will light steadily whenever
it is enabled. (Remember, depending on
