The intercom system shall be a Bogen Model PI35A.
The PI35A shall provide instantaneous intercommuni-
cation and background music (or other program) for
up to 25 speaker-equipped stations. A 20-watt inter-
com amplifier shall feature a frequency response that
has been shaped for maximum intelligibility. A built-in
35-watt program amplifier shall ensure that program
material and/or emergency announcements are clear-
ly heard and easily understood. The front panel shall
include step-by-step instructions and color-coded
guidelines for easy access and operation.
Complete facilities shall be provided for distributing
program material from microphones, CD player, or
other background music source. Distribution shall be
accomplished by simple push-button selection, follow-
ing color-coded guidelines. Emergency announce-
ments shall take precedence over program distribu-
tion and shall be accomplished with a single push-but-
ton selection and a built-in console microphone.
Provision shall be included to permit the distribution
of a time signal to all stations.
Optional paging facilities shall permit emergency all-
call paging from a remote telephone or microphone.
Telephone paging captures system priority and over-
rides all system functions except the emergency
page feature.
The PI35A shall include a built-in time tone that can
be sent to the entire system, supervisory tone to sig-
nal unauthorized monitoring from the control panel,
and monitor speaker to monitor a program or listen
to a station.
A room selector panel shall be provided to select
intercom and program functions for each station. Calls
from stations shall be initiated through call-in switch-
es and shall be announced at the control center by
light and tone annunciation. Provisions shall be made
for two-wire hook-up or voice call-in wiring.
The PI35A shall be enclosed in a space-saving console,
finished in an attractive simulated wood grain finish.
The system shall provide a 25-volt balanced output
and operate from a
1
20V AC, 60 Hz source. Maximum
power consumption shall be
1
00 watts. Dimensions
shall be 20-
