General Operation
After installing the ICS Page/Party® Plug-in Amplifier in the appropriate 702, 703, 732 or 733 Series
Enclosure, the operation is as follows:
Single party operation (multi-party operation in parentheses):
For paging and subsequent party line conversation, lift the handset or connect the headset, (select a free
party line using the five-position rotary switch.) Press the handset pressbar or headset switch, page the
desired individual (indicating which party line and) release the pressbar or headset switch. To reply, the
paged individual (selects the party line and) lifts the handset. Full-duplex communication can then be
held on the party line without broadcasting over the speakers. After the conversation is complete, all
parties place their handsets back on-hook.
The ICS Page/Party® station incorporates a noise-canceling microphone to reduce transmitted ambient
noise. This requires the user to place the microphone as close as possible to their mouth.
NOTE: An ICS plug-in amplifier model equipped with an auxiliary jack allows the user to be hands-free
and mobile while maintaining communication when used with the Model 10401-201 Headset and 10416103 Extension Cord. When connected, the handset microphone is disabled.

ICS AC-Powered Page/Party® Plug-in Amplifiers with VLC
Models 751-001ICSVC, 701-302ICSVC & 701-304ICSVC
The Volume Level Control (VLC) PCBA allows the amplifier to remotely control the local speaker
volume level. When VLC is activated, a remote device transmits a 50 kHz signal over the page line. The
station detects the 50 kHz signal and switches to an alternate speaker volume setting.
VLC provides an “alternate” speaker volume setting that is activated by receiving a 50 kHz signal on the
page line. Examples of its use are muting office or crew quarters speakers until a high priority message or
alarm is broadcast and/or reducing outdoor speaker volume at night. It can prevent local handset paging
during emergency conditions, and can also provide a relay output, which requires an RTU configuration.

ICS SmartSeries AC-Powered Plug-in Amplifiers
Models 751-901ICS, 701-902ICS & 701-904ICS
The SmartSeries PCBA adds microprocessor control to the Page/Party® station, providing additional
sensor and monitoring capabilities, such as Ambient Level Sensing (ALS) circuitry that changes the local
speaker’s paging volume in response to varying background noise, an off-hook timeout feature that
prevents noise being introduced to a party line by electronically placing the handset “on-hook” after 8
minutes, and a page timeout limits a single page broadcast to two minutes, freeing the page line for
emergencies.
When used with ADVANCE head-end equipment, the amplifier can monitor key components (including
handset, amplifier and local speaker) providing fast notification of any faults. In addition, it can accept
supervised contact closure inputs and provide a supervised relay output (requires RTU option).

Setting the Address
For the SmartSeries option to function properly, each station in an ADVANCE system zone must be
given a unique address using the hexadecimal switches, S1 (Hi Address) and S2 (Lo Address). Each
switch contains 16 settings, labeled 0–F. A small arrow on each switch indicates the setting.
Make a note of the address of the existing amplifier and use the same setting for the replacement
amplifier. The address settings are accessed through holes in the bottom of the ICS SmartSeries
Replacement Amplifier.
The station address is determined by the high address setting followed by the low address setting. For
example, to assign an address of 05, the high station address is set to 0 and the low address is set to 5.
Valid address settings are 05 to FE. If the SmartSeries PCBA is installed in a system without an
ADVANCE head end, set the address to 04 (default).

ALS Minimum Level
The ALS minimum level is the lowest speaker output level that the station will maintain. To set the ALS
minimum level, remove the amplifier from the enclosure and connect the maintenance cable (sold
separately). Turn R91 on the Main PCBA fully counterclockwise. Listen for a single beep from the
speaker indicating the speaker amplifier is in the Minimum Level Adjustment mode. If the page line is in
use immediately after the beep tone, the page signal should be used to make the minimum level
adjustment. If the page line is inactive following the beep tone, a continuous tone is activated to make the
minimum level adjustment. After the tone is activated, all page line activity is ignored until completion
of the adjustment.
This test tone is used as a reference to adjust the speaker amplifier output level to the desired volume.
Adjust R91 to the desired output. The test tone automatically shuts off 5 seconds after the last
adjustment. The factory default setting for minimum level is 4.0 watts nominal into an 8-ohm load.
ALS Offset Level
The ALS offset level allows the output of the speaker amplifier to maintain a set difference or “offset”
between the ambient noise level and the speaker output level. To set the ALS offset level, remove the
amplifier from the enclosure and connect the maintenance cable (sold separately). Turn R91 on the Main
PCBA fully clockwise and listen for the two beep tones indicating that the station is in the Offset
Adjustment mode. If the page line is in use immediately after the two beep tones are heard, the page
signal should be used to make the offset level adjustment. If the page line is inactive immediately
following the beep tones, a continuous tone is activated to make the offset level adjustment. After the
tone is activated, all page line activity is ignored until completion of the adjustment. Adjust R91 to the
desired offset level.
NOTE: This adjustment should be made under maximum ambient noise level conditions. The ALS offset
level must always be set higher than the ALS minimum level setting.
SmartSeries VLC Level
When activated, the VLC overrides the ALS minimum level setting allowing the speaker volume to
change to a preset level during an emergency page. To adjust the VLC Level, remove the amplifier from
the enclosure and connect the maintenance cable (sold separately). Force the station into the VLC mode
by having someone execute a page from a station programmed by the MCU to activate the VLC function.
During the page, turn the R91 control on the Main PCBA fully counterclockwise, and listen for two beep
tones through the page speaker indicating the VLC Adjustment mode has been activated. After the two
beep tones, turn the R91 control to the desired speaker level using the live paging signal to adjust the
level. The station automatically exits the VLC Adjustment mode and reverts to normal operation 5
seconds after the last pot adjustment.
NOTE: The system must be equipped with an ADVANCE head end to activate the VLC function.
FSK Signal Gain
The FSK Signal Gain, R13 on the SmartSeries PCBA, adjusts the FSK transmit signal strength. It is set
at the factory and should not be adjusted by the installer.

Paging with ADVANCE Head End
Paging and party line operation is similar to standard Page/Party® operation. The main differences are
that when the handset pressbar or the headset page switch is depressed a steady “wait” tone will be heard
in the handset or headset earpiece. When the “wait” tone ends, a pre-announcement tone, if programmed,
will sound, and the operator may place their page. If the system is busy and the page is denied, the user
will hear a busy tone in the handset or headset earpiece.
Paging without ADVANCE Head End
Paging and party line operation is similar to standard Page/Party® operation with the addition of an
optional pre-announcement tone being generated by the station at the beginning of each page.
Station Time-out Features
The ICS SmartSeries supports a page duration limit that sets the maximum duration of each page. If the
page is still active when the page duration limit is reached, the page will be terminated. When used
without an ADVANCE head end, the page duration limit is fixed at 2 minutes.
The ICS SmartSeries supports an off-hook limit that sets the maximum duration that the station may be
kept off hook. If the off-hook limit is reached, the station will be placed electrically on hook. To reset
the timeout condition, the handset must be physically placed on-hook momentarily. When used without
an ADVANCE head end, the off-hook limit is fixed at 8 minutes.
