SWU-8/3
The SWU-8/3 consists of 8 three-position toggle switches and 16
red or yellow LEDs. Each switch forms a distinct functional
group with two independently programmed LEDs. Placing a
switch in the up or down positions generates one of two active
(off-normal) conditions. The center position is the normal state.
In a typical HVAC application, the SWU-8/3 switches may be
used as hands off automatic (HOA) controls to override the
automatic operation of the system. The two associated LEDs
may be programmed to indicate the status of Run/Stop contacts,
fans or dampers with limit switches, etc.
In typical audio evacuation application using the SWU-8/3, the
upper switch position initiates circuit paging. The center switch
position allows normal/automatic control mode of the speaker
circuit. The LEDs indicate the active condition of the speaker
circuit.
