Connector J6 on the Base16 PCBA connects ac power to the Bias Power Supply PCBA and receives +5 V dc and +/-15 V dc in return. The Base-16 PCBA uses the bias supplies and also passes them (as well as control, monitoring, and line signals) to the FSK Modem and Handset Amplifier PCBAs via J1, a 24-pin stacking connector. Connector J2 on the Base-16 PCBA connects the speaker transformer for the station’s speaker, and J3 connects optional external devices. The Handset Amplifier PCBA has connections to the handset and the hookswitch via spade terminal connectors E1 to E7, and it has connections to the front panel auxiliary jack and the Receiver Isolation PCBA via J2. Figure 3. Block Diagram Interfaces The assembly interfaces to the system cable, an external loudspeaker, and auxiliary devices via P1, a 16pin connector. All connections to the system cable are made by qualified installation technicians during system installation. Direct questions about these connections to GAI-Tronics’ Field Service Department. Other connectors on the Base-16 PCBA provide quick connect/disconnect of subassemblies. Connector J3 on the side of the Base-16 PCBA connects to devices such as the relay module in a SmartSeries® Station Remote Terminal Unit (RTU) enclosure. Installation The assembly plugs directly into any GAI-Tronics 700 Series enclosure such as the Model 703A (indoor), the Model 7325-101 (cast aluminum outdoor), or the Model 7335-001 (nonmetallic outdoor). It also plugs into a SmartSeries® Station RTU enclosure. When installing the assembly in this enclosure, you must also connect the 10-conductor keyed ribbon cable to J3 on the side of the Base-16 PCBA. Be sure that the red line on the edge of the cable lines up with J3-pin 1. Ensure that the connectors mate securely and then tighten the 4 captive screws on the corners of the front panel. \\s_eng\gtcproddocs\standard ioms - current release\42004 instr. manuals\42004-605l2b.doc 03/04 Model 701-804 SmartSeries® Handset Station with Auxiliary Jack Pub. 42004-605L2B Page: 5 of 16 Operation Handset Operation Page Announcement 1.

From a multi-party enclosure, select an available party line. —OR— From a page destination enclosure, select the desired destination. 3. Press the handset pressbar. 4. When the wait tone stops, make your announcement. If the page resource is already in use, you hear a busy tone. Release the handset pressbar, then try again. 5. Release the handset pressbar. 6. When the party answers, conduct your conversation. When you are done, replace the handset in the cradle. Party-Line Conversation 1. For party-line conversation from a multi-party enclosure, first select the appropriate party line. 2. Lift the handset from the cradle. 3. Conduct your conversation. When you are done, replace the handset in the cradle. Auxiliary Headset Operation NOTE This application requires the GAI-Tronics Model 10401-201 Headset/Microphone Assembly and Model 10416-103 Extension Cable. The auxiliary headset allows the user to make one-way page announcements and conduct two-way partyline conversations hands-free from up to 30 feet from the station, while providing noise reduction for hearing protection. When an auxiliary headset/cable assembly is plugged into the auxiliary jack, a partyline connection is automatically established (the same as lifting the handset). Notes: 1. Leaving the auxiliary headset plugged in for a long period of time may disable party-line communication. This is controlled by the off-hook time-out setting, which can be 1 to 25 minutes in 1minute steps (the factory default is 8 minutes), or 0 (disabled, or no time-out). This feature ensures that a station unintentionally left connected to a party line will not induce unwanted background noise onto the party line. If party-line communication is disabled, unplug the auxiliary headset, then plug it back in. 2. The handset has priority over the auxiliary headset. When the handset is lifted from the cradle while the auxiliary headset is in use, the auxiliary headset’s microphone and page switch are disabled, but the headset receiver remains active. \\s_eng\gtcproddocs\standard ioms - current release\42004 instr. manuals\42004-605l2b.doc 03/04 Model 701-804 SmartSeries® Handset Station with Auxiliary Jack Pub. 42004-605L2B Page: 6 of 16 Page Announcement To make a page announcement for a party-line conversation, perform the following steps: 1.

The following standard programmable features are also accessible from the User Level Adjustment control on the front panel: User Minimum Page Output Level (or Minimum Level)—the minimum page output level of the speaker amplifier. Default setting: 4 watts. User Offset Added to Ambient (or Offset Level)—the amount of gain added to the ambient level so that an incoming page is not lost in the noise. Default setting: 9 dB. \\s_eng\gtcproddocs\standard ioms - current release\42004 instr. manuals\42004-605l2b.doc 03/04 Model 701-804 SmartSeries® Handset Station with Auxiliary Jack Pub. 42004-605L2B Page: 8 of 16 How to Diagnose Assembly Faults The table below describes possible solutions for some common problems. Problem Any problem with station performance Possible Solution Remove the assembly from the enclosure and examine it carefully for obvious faults such as unconnected plugs, loose connections where the wires from the handset and hookswitch connect to the Handset Amplifier PCBA, and so on. Determine whether the fault is in the assembly, or in the system, by plugging in a known good spare assembly (set to the same address as the assembly removed). If the fault is in the assembly, remove it for repair. Note: When replacing the assembly, perform the following steps: 1. Set the address on the new assembly to 03. 2. Plug the assembly into the enclosure. 3. After about 10 seconds, remove the assembly. The station is now set up to request a download of configuration variables from the Master Control Unit (MCU). 4. Set the address to the correct address. 5. Plug the assembly back into the enclosure. The station initiates a configuration download request. The time required to complete the download depends upon system configuration and system activity, but several seconds is typical. Speaker volume needs adjustment Use the USER ADJ control to adjust the Minimum Level, Offset Level, or VLC Level (as appropriate). Refer to the Adjustments section of this document. Incoming handset speech level needs adjustment Use the RCVR VOL control to adjust the handset receiver volume. Refer to the Adjustments section of this document. Incoming headset speech level needs adjustment Use the AUX VOL control to adjust the headset receiver volume. Refer to the Adjustments section of this document. Outgoing speech level is too low for other users Use the XMIT LEVEL control to adjust the audio transmit level. Refer to the Adjustments section of this document. Acoustic feedback or speech distortion during page or party operation • If the problem affects all stations, the line may not be terminated correctly, may have loose connections, or a short to ground. Line balance connections are critical. • If the problem affects only this assembly, the problem may be with its sidetone setting. Contact GAI-Tronics’ Field Service Department. or The user hears himself when speaking \\s_eng\gtcproddocs\standard ioms - current release\42004 instr. manuals\42004-605l2b.doc 03/04 Pub. 42004-605L2B Page: 9 of 16 Model 701-804 SmartSeries® Handset Station with Auxiliary Jack Problem Feedback during page only Crosstalk Possible Solution • Check within the enclosure for a purple wire on terminal 7: this is the default setting for local speaker mute. If the wire is on terminal 8, then the speaker is un-muted and may be causing feedback. Connect the wire to terminal 7. • An adjacent speaker could be causing feedback. If an adjacent speaker is the source of the feedback, adjust the orientation of the speaker so that it is not aimed directly at the station. As a last resort, enable the mutual muting function of the station. This is done by interconnecting terminal 7 of the two stations with the spare orange wire in the system cable (if this wire is available). Likely to be external to the assembly and related to system cable faults. When the assembly is in an ADVANCE system, faults may be automatically detected, transmitted to the MCU in data messages, and printed out. Fault messages and possible solutions for their causes are described in the table below. Fault Message Watch-Dog timer Processor has reset xd times (Where x is the number of times the watchdog timer has reset the processor.) Stuck Contact on Polled Device Paging Pressbar Depressed Stuck Contact on Polled Device Handset Off-hook Cause and Effect Cause—The watchdog timer has forced the processor to reset. This occurs when the reset pins (J4) on the Base-16 PCBA are temporarily shorted or when the watchdog timer does not receive regular status pulses from U2 on the Base-16 PCBA. Possible Solution • Verify that the reset pins (J4) on the Base-16 PCBA are not shorted. • Replace the Base-16 PCBA. • Verify that neither the handset pressbar nor the headset page switch is stuck. • Replace the Handset Amplifier PCBA. • Replace the Base-16 PCBA. • Verify that neither the handset is off-hook nor the headset is connected. • Replace the Handset Amplifier PCBA. • Replace the Base-16 PCBA. Effect—The processor maintains a count of the number of resets. If the station is powered down, the count restarts at zero. The station still amplifies incoming pages. On the fourth and subsequent resets, the x value in the error message is 0. Cause—The station has been in page mode longer than the configured page limit. Effect—Station page is cut off. When the pressbar is released, a restore message is sent to the MCU. The station then resumes normal operation. Cause—The station has been in the off-hook state longer than the configured time limit. Effect—Station handset/headset operation is cut off. When the station is returned to the on-hook state, a restore message is sent to the MCU. The station then resumes normal operation. \\s_eng\gtcproddocs\standard ioms - current release\42004 instr. manuals\42004-605l2b.doc 03/04 Pub. 42004-605L2B Page: 10 of 16 Model 701-804 SmartSeries® Handset Station with Auxiliary Jack Fault Message Cause and Effect Possible Solution Supervised Audio Path Cause—The station failed its internal health check of the Handset Amplifier PCBA. • Replace the Handset Amplifier PCBA. • Handset Effect—The station disables the handset amplifier health-check function after the first failure. This is a non-restorable fault. Replace the Base-16 PCBA. Supervised Audio Path Cause—The station failed its internal speaker amplifier health check. Replace the Base-16 PCBA. Page Amp Effect—The station disables the speaker amplifier health-check function after the first failure. This is a non-restorable fault. Supervised Audio Path Speaker Voice Coil • Verify that the speaker wire is connected and intact. • Verify that the voice coil is connected and intact. • Verify that the Offset Level adjustment is set correctly. • Replace the Base-16 PCBA. • Verify that the page line is connected and intact. • Verify that the station is installed correctly. • Replace the Base-16 PCBA. Cause—This message is the same as the “Polled device” fault, except that the affected station has been defined as an end-of-line station in the MCU configuration. • Verify that the page line is connected and intact. • Verify that the station is installed correctly. Effect—When this fault occurs, the red EOL FLT LED on the Page/Party® Interface (PPI) bezel lights. The LED extinguishes and a restore message is output when communication with the station is resumed. • Replace the station assembly. Cause—The station is detecting no ambient noise at the speaker or is detecting an ambient noise lower than the configured failure threshold. This may occur if there is a fault in the speaker wire or a fault at the voice coil. This also may occur if the ambient noise at the speaker is too low, as is the case in a quiet room. Effect—The station continues measuring speaker ambient noise. When acceptable noise levels are subsequently measured, a restore message is sent to the MCU. Polled device Cause—This message is output by the MCU when it loses communication with the station. This may occur if there is a fault in the page line, if the station is powered-down, or if there is some fatal malfunction within the station. Effect—The MCU continues to attempt communication with the station. A restore message is output when communication is resumed.

Inspect and replace frayed or cracked wiring. 2. Secure/replace loose wires and spade terminals. 3. Remove corrosion from terminals. There are two replaceable fuses used in the assembly. Both are mounted on the Base-16 PCBA, as shown in Figure 4, and both limit the amount of current from the 120 V ac source. • Fuse F1 (Ref. 10) limits the current to the speaker amplifier circuit on the Base-16 PCBA. This should be replaced with a UL-recognized 0.7-amp, slow-blow fuse. • Fuse F2 (Ref. 10) limits the current into the Bias Power Supply PCBA. This should be replaced with a UL-recognized 0.2-amp, slow-blow fuse. Figure 4. Control and Fuse Locations \\s_eng\gtcproddocs\standard ioms - current release\42004 instr. manuals\42004-605l2b.doc 03/04 Model 701-804 SmartSeries® Handset Station with Auxiliary Jack Pub. 42004-605L2B Page: 12 of 16 Adjustments This assembly includes one external control that permits adjustments to be made while the assembly is mounted in its enclosure and several internal controls that are accessible only by removing the assembly from its enclosure. External Adjustments The only externally accessible user adjustment is for setting the speaker amplifier gain for the SmartVolume™ feature, which has three components: Minimum Level, Offset Level, and VLC Level. Although they typically require no adjustments, these volume levels can be set with the User Level Adjustment control (labeled USER ADJ) located under the nameplate on the front panel, as shown in Figure 1. Use a small flat-blade screwdriver with an insulated shaft at least 4 inches long to make adjustments. To access the USER ADJ control, perform the following steps: 1. Loosen (do not remove) the 2 screws that secure the nameplate. 2. Pivot the nameplate counterclockwise, exposing the access hole. A guide located behind the access hole helps to direct the screwdriver to the USER ADJ control. 3. After making the adjustment, pivot the nameplate clockwise into position, then tighten the 2 screws. Minimum Level The Minimum Level adjustment sets the minimum output of the speaker amplifier. The amplifier can be set from minimum to full output (12 watts into 8 ohms) in 100 discrete steps, or to no output. The factory default is step 20, providing 4 watts. To adjust the Minimum Level, perform the following steps: 1. Turn USER ADJ fully counterclockwise and wait to hear a single beep over the station’s speaker. This switches the station into the Minimum Level adjustment mode. If there is an audio signal on the page line when the station enters this mode, you hear it over the speaker. Otherwise, you hear a station-generated test tone. 2. Turn USER ADJ clockwise to the desired minimum speaker volume level. The station remains in the Minimum Level adjustment mode for as long as USER ADJ is varying. After USER ADJ has remained stable for five seconds, the station returns to its normal operating mode. \\s_eng\gtcproddocs\standard ioms - current release\42004 instr. manuals\42004-605l2b.doc 03/04 Model 701-804 SmartSeries® Handset Station with Auxiliary Jack Pub. 42004-605L2B Page: 13 of 16 Offset Level The Offset Level adjustment causes the speaker amplifier to maintain a set difference between the ambient level and the speaker output level. The SmartVolume™ feature measures the ambient noise at the station’s speaker and adds the Offset Level to set the speaker amplifier gain. This keeps page announcements louder than the ambient noise. The Offset Level can be set from 0 dB (the speaker output level is the same as the ambient level) to 49 dB. A speaker should be set for 6 to 10 dB louder than the ambient noise, so the factory default is 9 dB. Note: There must be enough ambient noise for the station to sense. The exact level depends upon the speaker type, but it is typically approximately 80 dB. To adjust the Offset Level as follows: 1. Turn USER ADJ fully clockwise and wait to hear two beeps over the station’s speaker. This switches the station into the Offset Level adjustment mode. If there is an audio signal on the page line when the station enters this mode, you hear it over the speaker. Otherwise, you hear a station-generated test tone. 2. Turn USER ADJ counterclockwise to the desired speaker volume level. The station remains in the Offset Level adjustment mode for as long as USER ADJ is varying. After USER ADJ has remained stable for five seconds, the station returns to its normal operating mode. VLC Level The VLC Level adjustment sets the speaker amplifier gain for the Page Priority VLC feature to provide an emergency output level. The amplifier can be set from minimum to full output (12 watts into 8 ohms) in 100 discrete steps, or to no output. The factory default is step 10, but the System VLC Control feature is disabled. To adjust the VLC Level, perform the following steps: 1. Have an assistant make a page from another station that forces the station being adjusted into VLC mode. 2. Turn USER ADJ fully counterclockwise and wait to hear two beeps over the station’s speaker. This switches the station into the VLC Level adjustment mode. 3. Turn USER ADJ clockwise to the desired speaker volume level. The station remains in the VLC Level adjustment mode for as long as USER ADJ is varying. After USER ADJ has remained stable for five seconds, the station returns to its normal operating mode. Internal Adjustments Although they typically require no adjustments, the following volume levels can be set with internal controls: Audio Transmit Level, Handset Receiver Volume, Auxiliary Receiver Volume, and Tone Volume. To make an adjustment, it is necessary to remove the assembly from its enclosure and make a temporary connection between the assembly and the enclosure. Refer to Figure 4 for the reference numbers and locations of the adjustment controls. Turn a control clockwise to increase the volume or threshold; turn it counterclockwise to decrease the volume or threshold. Use a small flat-blade screwdriver with an insulated shaft to make adjustments. \\s_eng\gtcproddocs\standard ioms - current release\42004 instr. manuals\42004-605l2b.doc 03/04 Model 701-804 SmartSeries® Handset Station with Auxiliary Jack Pub. 42004-605L2B Page: 14 of 16 To access the controls, perform the following steps: 1.
