DAY/NIGHT MODE TOGGLE
This command sends a PA On command to all stations, puts the Model 26 in the Day
mode (PA On), and turns both LEDs on. If the button is pressed again, it returns the PA
systems to the Normal or Night mode (PA Normal), until the button is pressed again. The
system continues to poll the stations while in the Day mode, but the PA systems at the
stations are available to the dispatcher for making announcements simply by keying the
mic. Individual stations may be alerted, or have their PA systems turned off, but the
typical scenario leaves all PA systems on for all announcements during the day, and
returns the PA systems to normal operation at night.
Relay Buttons
Relay buttons represent commands for the general-purpose relays in a Model 6 (there are
four such relays in each Model 6, six additional relays may be added with the Optional
Relay Enhancement kit). The Model 6 does not return its relay status to the Model 26.
There are no corresponding relay buttons on the Model 6s. There are two types of relay
buttons.
The first type turns a particular relay on or off at a particular station. This type uses up a
button position on the Model 26, similar to the Alert or PA on buttons. Pressing this relay
button sends one of the following relay commands to its assigned relay.
RELAY ON - This Relay command turns on a relay at a Model 6.
RELAY OFF - This Relay command turns off a relay at a Model 6.
The second type is a system override button. When pressed, it turns ON or OFF
whichever relay is assigned to it at all of the stations. In actual operation, you press the
Relay N - ON/OFF system button followed by a specific station or unit button to indicate
which relay the operation is intended for.
If it is desired to show the current status of a relay at the Model 26, one set of contacts on
the relay should be wired to one of the sense inputs at the Model 6. The condition of this
sense input can then be displayed on the LEDs associated with the relay button at the
Model 26.
LEDs
There are LEDs on both the front and rear panels of the Model 26. The LEDs on the rear
panel are normally not visible to the dispatcher. They are for use by maintenance
personnel.
