LIGHT CONTROLS
A 4-position slide switch provides control of primary lighting functions. It also provides automatic
activation of the siren. Four pushbuttons for additional lighting or controlling other devices. The
power switch on the hand control must be ON for light controls to function.
Slide Switch
The slide switch provides progressive (additive) control of lighting
functions. Position 1 turns on L1 output. Position 2 turns on L1 and
L2 outputs. Position 3 turns on L1, L2, and L3 outputs. Position 3
also turns on the siren (Automatic Siren).
The slide switch position outputs OUT1 and OUT2 are for setups
that require a non-progressive slide switch. Only Position 1 will turn
on OUT1. Only Position 2 will turn on OUT2. In Position 3 the L3
output can be used since only Position 3 will turn this on.
Note that OUT1 and OUT2 are not fused
and intended to drive external relays. These outputs
can only drive loads up to 500mA each.
Slide Switch Reverse
The Option Switch can be set to reverse the slide switch positions. Position 1 and Position 3
operations are reversed or swapped.
Automatic Siren
Position 3 of the Slide Switch (or 1 with Slide Switch Reversed) provides Automatic Siren. If the
siren controls are set where there is no siren tone output, the Automatic Siren will override with
Wail. The only exception is PA Override or Cutout activation.
Automatic Siren may be disabled with the Option Switch.
Auxiliary Output Switches
Four pushbutton switches are provided for various other lighting
functions or device control. Legends above the switch light up
when the switch is on.
Legends
Different legends may be selected to match the device controlled
by aux output switch. A sheet of stick-on legends is supplied.
Select the legend and place centered over the legend area. Press down on the legend to stick
over clear window and tuck under rubber framing. Gently lift up on the sides of rubber framing to
help cover the edges of the legend.
To remove a legend, use a thin edge to gently push rubber frame aside and pry between legend
and clear window. Try not to puncture clear window. The stick-on adhesive is strong.
Blank (black) legends are provided for aux output switches with no function. The white back-
ground legends may be written on with permanent marker to create custom legends.
