Operating the Model 26
88 025-9158L
UNIT ALERT WITHOUT PA
This command changes a unit’s status to “Alert” at a Model 6, but does not enable the
PA system at the station. There are no buttons representing this command on the Model
6. This command might be used instead of the “Unit Alert With PA” command if the
Model 6 is not being used to control the station’s PA system.
UNIT ALERT OFF
This command changes a unit’s status to “Not Alerted” at a Model 6, and turns off the
station’s PA. There are no buttons representing this command on the Model 6 however,
pressing an alerted unit’s QRTRS/AIR button will turn off the alert (refer to Model 6
Station Transponder Product Manual, Part No. 025-9157). This command could be used
if the dispatcher had mistakenly pressed the unit’s alert button. Unit buttons for this
command are not normally found on the Model 26. This unit command is more
efficiently handled by a system button using the same command.
ALL UNITS ALERT
This command changes the status of all units at a station’s Model 6 to “Alert” and turns
on the station’s PA. A dispatcher uses this command to alert all the units at a station and
to turn on the station’s PA system for toning and dispatch instructions.
Before the Model 6 returns a PA ON status it must first finish sending any alert tones that
have been programmed to sound (refer to Model 6 Station Transponder Product Manual,
Part No. 025-9157). Once the Model 26 receives the PA ON status from the Model 6, the
dispatcher may key the microphone at the Model 26 and speak. If the microphone is not
keyed before the Wait for Dispatcher Time-out expires (refer to
Wait for Dispatcher
Timeout on page
46), the Model 26 sends a PA OFF command to the Model 6.
As long as the dispatcher’s microphone remains keyed, the PA at the Model 6’s station
continues broadcasting the dispatcher’s announcements. When the dispatcher is finished
and unkeys the microphone, the Model 26 waits the Hold After Dispatch Time-out to
expire before sending a PA OFF command to the Model 6.
There are no buttons representing this command on the Model 6. For more information
on how the Model 26 controls PAs through the Model 6, refer to
Alert with PA
Commands on page
95.
Station Buttons
Station buttons represent commands to a single station. Each station type button is
addressed to only one station. Pressing a station type button sends the associated
command only to one station. All station commands can also be represented by system
type buttons that do not carry an address (refer to
System Buttons on page 90).
