Digital Feedback Elimination
Eliminates the acoustical feedback loop created by the
telephone handset and the paging speaker, while provid-
ing high-capacity, high-quality recording and playback of
audio pages. Ability to record a message while another is
played. Stacks up to 8 messages for playback. 120 seconds of total audio
memory. Automatic or externally controlled unit operation for recording, play and
stop. Activates recording by loop start trunk, 4-wire dry loop, audio trigger or
DTMF. Digital recording and playback of pages, 30-second maximum message
length. Adjustable delay times between messages. Message repeat, abort,
stop, and pre-page tone options. Zone control DTMF tones stripped from mes-
sage and regenerated. 8- or 600-ohm output impedances. Easy installation and
low maintenance. Volume control. Wall-mountable.
Night Ringer
Converts any paging system into an after-hours night
bell alert system. Connects to the paging system's
amplifier and emits a ringer tone through the paging
system's speakers. Responds to 90V ring signals or
external contact closures. Produces dual-frequency
electronic ringer tone. Automatically mutes
background music while ringing. Ringer volume control. Compact size.
Low current draw. No maintenance. FCC Part 68 approved.
Ambient Noise Sensor System
Automatically adjusts the paging level in response to
changes in the ambient noise of an area. Small
sensor microphones monitor the ambient noise levels
in an area served by a single amplifier. Will adjust (boost or reduce) the input
signal levels to the amplifier to ensure that the paging announcements will be
heard at an audible, clear and comfortable level over the current ambient noise.
Supports up to four small sensor microphones (one ANS500M included) for
large areas.
Voice-Activated Relay
A relay device that monitors audio activity over a wide range
of input voltages and operates two sets of C-Form relay con-
tacts in response to detected activity. Can be used to detect
voltages as low as signals directly from a microphone or as
high as signals from 70V speaker systems. Two sets of C-
Form (both N.O. and N.C.) relay contacts respond to audio activity. Four levels
of input trigger threshold adjustment. Adjustable release delay - 0.25s to 25s.

Attenuators
Allows the output level of a group of loudspeakers to
be set from a wall-mounted volume control, without
affecting overall amplifier volume settings. These
rugged attenuators have 10 levels of sound control,
plus an off-setting. Mounts in standard electrical box.
