Simple Connections
Wiring consists of connecting the night
answer port of the telephone system to the
ringer inputs. The ring signal can be the
actual 90V ring signal or it can be from a
contact closure. The output of the NR100
connects to any paging system.If there is
background music in the system,that too is
fed to the NR100. When the night line
rings, the NR100 will suppress the back-
ground music and begin to feed the elec-
tronic ring tone over the paging system.
Background music will not be reapplied
until the line stops ringing to ensure that
no background music will be heard in be-
tween bursts of ring signal.
ANS501
with Sensor
Microphone
Bogen's Ambient Noise Sensor System electronically adjusts the level of a page
or background music in applications where ambient noise levels are continuously
changing. The ANS501 ensures that page announcements or background music are
intelligible even during periods of high ambient noise levels. The system includes
a sensor microphone module (ANS500M) that monitors the ambient noise level,
and a 12V DC power supply.

NR100
The NR100 converts any paging system into an
after-hours night bell alert system. The NR100
connects to the paging system’s amplifier and
emits a ringer tone through the paging system’s
speakers, thus eliminating the need for loud
old-fashioned bells positioned throughout a
facility. The NR100 is an efficient and easy way
to alert security or personnel of incoming calls
during non-business hours.
Music Bypass Input
Ambient noise controllers are a great benefit in
applications where ambient noise conditions
change significantly. Typically, these controllers
raise and lower all the inputs to a sound system.
However, there are instances where it may be
desirable to keep a certain input from changing
in response to ambient noise. A good example
of this is a restaurant or lounge situation where
background music is supplied at low levels to
make the area seem less empty during quiet
periods. Normally the background music is sim-
ply overpowered by the ambient noise of the
crowd as it builds and this is desirable since the
background music is of no real importance. It
would be undesirable in this situation to have
the background music increase in level as the
ambient noise increases since the background
music would only add to the ambient noise level
and annoy the patrons. The ANS501 provides a
special AUX input just for this type of applica-
tion. This input is mixed into the output of the
ANS501 after any level changes have been made
and will not change with the ambient noise
level. All other signals sent to the ANS501's
normal input, like paging announcements, will
have their level changed in response to changes
in ambient noise, but the AUX Input level
will re-
main fixed.
