Front Panel Description
The front panel of a Model 26 consists of 10 columns of six buttons each for a total of 60
buttons for sending commands. Each button has two light-emitting diodes (LEDs)
associated with it: one green and one red for indicating status.

Buttons
The Model 26 serves as a command sender and a status receiver. Each button, or
combination of buttons, on its front panel represents a command. When a button is
pressed, a command is sent to a specific Model 6 or a predefined group of Model 6s.
These commands can turn on a PA system for dispatching a vehicle, activate relays to
open overhead doors and turn off lights or appliances, to mention some possibilities.
The configuration of these buttons is user definable; however, the configuration must be
programmed into the Model 26’s memory by the factory. The configuration can only be
changed by replacing the unit’s ROM chip with a reprogrammed one obtained from
Zetron.
Status Indicators
Each button on the Model 26 has two LEDs adjacent to it, one green and one red. By
displaying different combinations of on, off, and blinking, the LED pairs can indicate as
many as nine current statuses. The LEDs associated with Unit buttons usually show unit
status such as Available or Responding. The Station button LEDs normally indicate
station status such as Off Line and PA operation. The LEDs can also be used to indicate
the status of up to four sensors connected to the Sense Inputs of a Model 6.
