The brass push button is used primarily with the 6300 and 5100 Series displays and is wired to the back of the displays with 22 AWG 2-conductor wire. If the display is in counter mode,
it will advance the number on the display one at a time,
or it can be wired to decrease the number on the display. If the display is in timer mode,
the push button will start or stop the timer. Unlimited push buttons may be wired to a display.
The brass push button is also used with the DigiLink Transmitters for zone paging applications. Also known as doorbell buttons,
other uses include: contact closure (relay switch),
or remote delete.
