External Switch
An external switch is a hardware switch used to mimic a keypad operation completely. The
DW800/820 allows for only the ZERO external switch.
A momentary, normally open, switch must be connected between “Pin 01” and “Pin 09”.
External ZERO is activated when the switch is closed.
To avoid erratic operation the switch cable must be less than 10 feet.
