Paging to Field Stations
To page to field stations, complete the following steps:
1. Select the desired Z ONE S ELECT push buttons (1 through 5 or ALL). This could be one zone, a group
of zones, or all zones. The green LED indicator(s) for the selected zone(s) illuminate.
2. Lift the handset, press the handset pressbar, and speak directly into the microphone. The page message
is broadcast from speakers in the selected zones.
3. To reset the system, press the Z ONE S ELECT RESET push button.
N OTE : If the ALL push button is pressed, it merges all zones automatically. To reset the zones, press the
Z ONE S ELECT RESET push button.
Speaker Volume Control
Use the VOLUME knob on the Model MS05-101S Desktop Master Station Subset to adjust the front panel
speaker volume. Turning the knob clockwise increases the speaker volume, and turning it counterclockwise
decreases the volume.
The front panel volume control does not affect any external speaker that is connected to the master station.
The speaker volume for any externally-mounted speakers is controlled using the amplifier volume control
located under the GAI-Tronics nameplate on the front of the amplifier.
N
OTE : A small screwdriver is required for making this adjustment.
Fault Indicators
Two types of indication are provided for data communication faults between the master station(s) and the
merge/isolate cabinet.
1. If data communication lost between a master station and the merge/isolate cabinet, all the LED
indicators on the affected master station subset subset will flash. All alarm and zone selection features
are disabled during this type of fault. Party line communication on party lines 2–5 is unaffected.
Paging is still possible to other master stations.
2. The red FAULT indicator on the subset is only functional when multiple master stations are installed in
the system. When the FAULT indicator illuminates there is a data fault between the merge/isolate
cabinet and one of the other master stations in the system. It does not indicate a data fault at the local
master station.
Possible causes of data fault conditions include:
• A defective master I/O controller board in the merge/isolate cabinet.
• Improper switch setting of the master controller switches in the merge/isolate cabinet;
• Missing or reversed data cable connection between a master station and the merge/isolate cabinet.
• A defective I/O controller board in a master station.
