Using the System
(continued)
Microphone peak detection:
Both microphones have peak detection circuits that allow the headend to monitor peak values for
a given time period.
Variable gain:
Both microphones have variable gain circuits that allow the headend to choose whether to use standard
gains of ultra-high sensitivity mode, which allows the security team to listen in to each
Talk Back
unit to
locate small sounds within the space. This feature works hand-in-hand with a remote Push-To-Talk
feature that will activate the microphone in a given room, even if no one presses the button. This is
highly beneficial in situations where people may be hiding in the area, and motion detection may not
pick them up, but audible noise can.
Speaker relay:
The speaker relay connection goes to a special Lencore Speaker that is relay activated. This connection
provides a switched 24vdc signal that either activates the local speaker or not. This signal is triggered
by the security office page to the given room. This will allow a signal speaker on a channel of 8
speakers to be enabled, based on the zone/room page. This allows a single OP channel to service
multiple rooms and still be able to enable a single speaker on the run.
