Sending Model 6 Commands

The buttons on the front panel of the Model 26 are used to send commands to the Model

6 (refer to

Front Panel LEDs on page 92). Pressing one of these buttons, or a

combination of buttons, causes the Model 26 to immediately send the command selected

to a Model 6, or a group of Model 6s. After a Model 6 receives a command, it acts on the

command and returns its new status to the Model 26. This confirms that the command has

been received and carried out successfully.

All Model 26 buttons can be grouped into the following four general categories:

• Unit buttons

• Station buttons

• System buttons

• Relay buttons

Each category is discussed in the following subsections. Each button on the Model 26 can

be programmed at the factory to perform one of the functions described in the following

paragraphs, as specified by the customer.

Unit Buttons

Unit buttons serve those commands sent to single units at a single station. Each unit type

button is addressed to only one unit (vehicle). Pressing a unit button sends the associated

command only to one unit. All unit commands can also be used by system type buttons

that do not carry an address (refer to

System Buttons on page 90). Most unit commands

are status changes and have an LED representation on the Model 6.

Every unit in the system should have at least one unit button on the Model 26. This

allows their status to be displayed and their addresses can be used by system buttons.

Usually this button would be a “Unit Alert” button. All other unit commands are much

more efficiently handled (space wise) by system buttons.

The Unit commands that can be associated with a unit button or a system button are as

follows:

IN QTRS

This command changes a unit’s status to “In Quarters”, at a Model 6. This status typically

indicates that a Unit is both at its quarters and available for service. Normally, this

command would be initiated at the Model 6 when the QRTRS button is pressed. 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.
