Mounting the Enclosure

Mount the enclosure using the four 0.312-inch(8 mm) diameter holes located on the mountingflanges with -inch (M6) hardware. The ICS

remote subset amplifier is not supplied withconduit or cable openings.

Remove the front panel and drill or punch entryopenings in the rear section of the enclosure.Refer to Figure 2 for the suggested locations.There must be a minimum of inch (13 mm)of material between entry holes.

The station is suitable for top or bottom entryper Figure 2. However, GAI-Tronics

recommends bottom entry only whereverpossible.

For specific details including mounting holedimensions, refer to Figure 2. When mountingthe enclosure, use caution to avoid damagingthe internal components.

The suggested mounting height for all stationenclosures is 48 inches (1219 mm) to the center

of the bottom mounting holes of the enclosure.

NOTE: In ICS Page/Partystations with an

installed 70V/100V speaker output option,bottom wire entry is limited on the bottom left

side of the enclosure. Refer to Figure 2.

Field Wiring

The ICS Page/PartyStation provides terminal blocks for field wiring. Each connection for the systemcable has two terminals for daisy-chain wiring. Attach #6 spade lugs to the wires before attachment to theterminal blocks for the most secure connection.

The terminal blocks on the remote amplifier Termination PCBA are labeled to coincide with the color

code used on GAI-Tronics 60029 series multi-party cable or 60038 series single party cable. Refer toFigure 3 for a sample wiring diagram.

In certain circumstances where paging audio induces feedback, muting the speakers of two or more

stations during a page, referred to as mutual muting, can eliminate such feedback problems. This functionis enabled by connecting the spare orange wire between stations to terminal block TB4-2 or TB5-2.

Figure 3. Typical ICS Page/PartyStation Wiring Diagram

After all wiring and cable connections have been completed, place the front cover on the rear enclosure,

being careful not to pinch any cables. Secure the front cover using the four screws and washers provided.Torque the screws to 1012 in-lbs (1.131.36 n-m).

Jumper Settings

Speaker Mute

The station can mute the speaker amplifier during page operation to eliminate feedback. P11 in the ENposition (default) mutes the speaker during page activation. P11 in the DIS position allows broadcast tothe speaker during paging.

Speaker Gain Setting

P9 can limit the maximum speaker output level. P9 in the HI position (default) represents a 30-watt

maximum output. P9 in the LO position represents a 2-watt maximum output.

WARNINGMaximum output power may exceed rated speaker wattage resulting in speaker

damage.The P9 2-watt speaker gain setting is designed for use when the external speaker is placed in a quietenvironment, such as an office. The 2-watt setting allows for more minute volume adjustments to thespeaker. However, this affects the internal speaker output volume for desktop units as well.

7/26/2019 42004-726L2F

10/30




09/13

For such applications, the use of a GAI-Tronics No. 12506-001 Remote Volume control is recommended.

This allows the P9 speaker gain setting to be left at the 30-watt setting, while allowing maximum controlof the external speaker volume. This configuration will also not affect the internal speaker volume levelof the desktop unit.

Level Adjustments

Transmit Level

The Transmit Level potentiometer, R34, adjusts the signal level from the handset or optional auxiliary

headset microphone to the page or party lines.

Receiver Volume

The Receiver Volume potentiometer, R5, adjusts the signal level to the handset receiver from the page orparty lines.

Speaker Volume

The Speaker Volume potentiometer, R91, adjusts the signal level to the speaker from the page line. The

default setting is 4 watts for an 8-ohm speaker and 2 watts for a 16-ohm speaker.

Warning Maximum output power may exceed rated speaker wattage resulting in speaker damage.

Attach the Front Panel

After all adjustments have been completed, place the front cover on the rear enclosure, being careful notto pinch any cables. Secure the front cover using the four screws and washers provided. Torque the

screws to 1012 in-lbs (1.131.36 n-m).

OperationFor paging and subsequent party line conversation, the station operator lifts the handset on the remotesubset, selects a free party line using the five-position rotary selector switch (if equipped), and presses thehandset pressbar. The station operator pages the desired individual and designates the party line on whichthat individual should respond. The individual then responds by approaching the nearest ICS Page/Partystation, selecting the appropriate party line and lifting the handset. Full-duplex communication can then

be held on the party line without broadcasting over the speakers. After the conversation is complete, allparties should place the handset back on hook.

Options

The ICS remote subset amplifier station options can be factory installed or field installed in some cases.The field installable options include ICS SmartSeries, VLC, and RTU.

ICS SmartSeries

General

The 69552 SmartSeries PCBA adds microprocessor control to the ICS Page/Partystation, providing

additional sensor and monitoring capabilities. SmartSeries and VLC PCBAs cannot be installed in thesame station.

Features

When used with or without ADVANCE head-end equipment:

Ambient Level Sensing (ALS) circuitry automatically changes the local speakers paging volume inresponse to varying background noise. (Not available when 70V/100V speaker output option isused.)

Off-hook timeout prevents noise being introduced to a party line by electronically placing the handseton-hook after 8 minutes

Page timeout limits a single page broadcast to two minutes, freeing the page line for emergencies

When used with ADVANCE head-end equipment:

Station monitoring of key components (including handset, amplifier and local speaker) provides fastnotification of any faults. (Local speaker monitoring is not available when 70V/100V speaker

output option is used.)

Ability to accept supervised contact closure inputs and provide a supervised relay output (requiresRTU option)

Installation and Adjustments

Opening the Station



box interior now face you. This configuration presents the easiest access for troubleshooting and settingadjustments.

Installing the SmartSeries PCBA

Remove power from the station.

Remove all jumpers on the Main PCBA P4 connector.

Align the SmartSeries PCBA with four mounting holes to the right of the Main PCBA with the edge ofthe SmartSeries board under the Main PCBA. Secure the SmartSeries PCBA with the four screws

provided.

Install the provided 34-pin ribbon cable from P4 of Main PCBA to P4 of SmartSeries PCBA.

Reapply power to the station.

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). Eachswitch contains 16 settings, labeled 0F. A small arrow on each switch indicates the setting.

The station address is determined by the high address setting followed by the low address setting. Forexample, 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. Record the address assigned for each station in the system for your

records. If the SmartSeries PCBA is installed in a system without an ADVANCE head end, set theaddress 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, turn R91 fully counterclockwise. Listen for a single beep from the speaker indicating thespeaker amplifier is in the Minimum Level Adjustment mode. If the page line is in use immediately afterthe 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 lastadjustment. The factory default setting for minimum level is 4.0 watts nominal into an 8-ohm load.

7/26/2019 42004-726L2F

13/30




09/13

ALS Offset Level

The ALS offset level allows the output of the speaker amplifier to maintain a set difference or offsetbetween the ambient noise level and the speaker output level. To set the ALS offset level, turn R91 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 tomake the offset level adjustment. If the page line is inactive immediately following the beep tones, acontinuous tone is activated to make the offset level adjustment. After the tone is activated, all page lineactivity 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. The ALS offset level mustalways 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, force the station into theVLC mode by having someone execute a page from a station programmed by the MCU to activate theVLC function. During the page, turn the R91 control fully counterclockwise, and listen for two beeptones 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 5seconds after the last pot adjustment.

NOTE: The system must be equipped with an ADVANCE head end to activate the SmartSeries VLC

function.

Speaker Impedance Supervision

When this feature is configured, the station will supervise the speaker line for changes in the speaker lineimpedance. To perform this function the station must be calibrated for the impedance of the speaker(s)

attached. If the station has never been previously calibrated, the station will report a speaker fault within15 minutes of being configured for this feature. The station may be calibrated either locally at thestation or remotely by a system command from the ADVANCE head end. See the ADVANCE System

Programming Manual for details of remote calibration.

To perform a local calibration, first ensure that the station is configured for speaker impedance

supervision. Next, set the station's address to 0x02. Wait until you hear a single-beep tone at the attachedspeaker. This should occur within 20 seconds. This tone indicates that a successful calibration was

performed.

If instead a double-beep tone is heard, this indicates that the station attempted to calibrate but wasunsuccessful (the attached impedance is out-of-range). If a tone is not heard, the station may not be

configured for speaker impedance supervision or there is an open connection to the speaker.

After hearing the single beep tone, set the address back to its original value to resume normal station

operation with the new calibration value.NOTE:If this feature is used, then jumper P9 of the Main PCBA must be in the HI (default) position.

FSK Signal Gain

The FSK Signal Gain, R13, adjusts the FSK transmit signal strength. It is set at the factory and shouldnot be adjusted by the installer.

Attaching the Front Panel

After all adjustments have been completed, place the front cover on the rear enclosure, being careful not

to pinch any cables. Secure the front cover using the four screws and washers provided. Torque thescrews to 1012 in-lbs (1.131.36 n-m).

Operation

Paging with ADVANCE Head End

Paging and party line operation with the ICS SmartSeries option is similar to standard station operation.

The main differences are that when the handset pressbar or the headset page switch is pressed, a steadywait tone will be heard in the handset/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/headset earpiece.

Paging without ADVANCE Head End

Paging and party line operation will be similar to standard station operation.

Station Time-out Features

The ICS SmartSeries option 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 usedwithout an ADVANCE head end, the page duration limit is fixed at 2 minutes.

The ICS SmartSeries option supports an off-hook limit that sets the maximum duration that the stationmay 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 usedwithout an ADVANCE head end, the off-hook limit is fixed at 8 minutes.

50 kHz Alignment

The 50 kHz alignment, R5, adjusts the receivers frequency for VLC operation. It is set at the factory andshould not be adjusted by the installer.

Speaker Mute

P26 allows for the installer to mute the speaker audio during VLC operation or normal operation. In the50kHz position, the audio is muted during a VLC broadcast. In the NORM position, the audio ismuted during normal operation. To operate the unit without the muting feature, remove P26.

Audio Alignment

To set the normal speaker output level, set DIP switch SW2-1 to the off position. Set SW2-2 to theon position to enable a reference test tone. Adjust R91 on the Main PCBA (refer to Figure 6 forlocation) to the desired audio level. To mute the audio, turn R91 fully counterclockwise and put P26,

MUTE, in the NORM position.

NOTE: If LED2 on the VLC PCBA is on, indicating the system VLC tone is present, this adjustment

cannot be made.

To set the VLC controlled speaker output level, set SW2-1 to the on position. Set SW2-2 to the onposition to enable a reference test tone. Adjust R12 on the VLC PCBA to the desired audio level. Tomute the audio, turn R91 fully counterclockwise and put P26, MUTE, in the 50KHz position.

Troubleshooting

Opening the Station

Remove the four screws from the front panel and turn it to the right so that the interior surface faces you.Allow the wiring and ribbon cables to remain connected. Using two of the screws just removed, mountthe front panel to the back boxs right-side mounting holes. The front panel interior surface and the back

box interior now face you. This configuration presents the easiest access for troubleshooting and settingadjustments.

Front Panel PCBA Jumper Settings & Adjustments

The front panel PCBAs are protected by a universal shield. Most potentiometer adjustments and jumpersettings can be made without removing the shield. Refer to Figure 17 for adjustment locations.

P4 Standard Jumper Configuration

For standard operation, without options, P4 requires jumper installation for proper operation. See Figure17 for jumper locations.
