Strobes
Strobe lights are used to provide either a primary or secondary warning system in 20 or 30 Series Lightbars. Each strobe power supply con-
trols four strobe heads. Of those available, the standard flash pattern is alternating quad-flash, 140 flashes per minute. The flash pattern is
not user-configurable. The strobe power supply is multi-voltage and will operate at both 12V and 24V.
There are three types of strobe head available – 'linear' and 'directional' for both upper level and lower level of the light bar. Strobe tubes
can only be replaced on the linear and lower deck directional style heads.

eye protection should be worn when handling strobe lamps as they are pressurized and accidental breakage can
result in flying glass.
