PAGING ELECTRONICS
VOICE-ACTIVATED RELAY
The VAR1 is a relay device that monitors audio activity over a wide range of input voltages and operates two
sets of C-Form relay contacts in response to detected activity. The VAR1 can be used to detect voltages as low
as signals directly from a microphone or as high as signals from 70V speaker systems. A low-level
output of the
detected audio, transformer-isolated from the input, is also available for use with other equipment.
The VAR1 can
also be used as a balanced, low-impedance MIC pre-amp
.
Product Features:
• Automatically adjusts paging level as
ambient noise levels rise and fall
• Balanced and unbalanced input and output
• AUX inputs bypass gain control feature
• Unbalanced stereo AUX inputs (summed
mono)
• Supports up to 4 sensor microphones
(one ANS500M included) wired in parallel
for large areas
• Sensor microphones can be located up
to 2,000 feet from control unit
• Only 2 wires needed for connection
of sensor microphones
• Microphone module includes an
adjustable mounting bracket for
precise positioning
• Connects easily between pre-amp and
power amp or to amplifier insert jacks
• Sensitivity and max boost control
• Adjustable ramp speed

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.
Product Features:
• Responds to 90V ring signals or external
contact closures
• Produces dual-frequency electronic
ringer tone
• Easily connects to any paging system
• Automatically mutes background music
while ringing
• Ringer volume control
• Compact size
• Low current draw
• No maintenance
• FCC Part 68 Registered
