Maintaining and Servicing the Valor
Problem
Corrective Action
The light bar has a delayed
response to being shut off
• Ensure that the connections on the Serial Interface Module are kept
separate from strobe supplies.
• Check all the ground connections, especially on the Serial Interface
Module.
A Flash Takedown/Alley light stays
on with ignition power applied
• Ensure there is no voltage on the corresponding control wire.
• To see if the ROC board is bad, swap it with a similar board.
• Swap the cables on the light bar controller outputs with a known
good output. If the problem moves to another halogen light, send
the light bar controller to Federal Signal for repair.
Takedown/alley lights work, but
Flash Takedown/Alley lights do not
work
• Ensure that 12 Vdc is applied to the takedown and alley (red/black)
control wire.
• Check the 12 Vdc power and negative ground connections to the
light bar to ensure there is enough current.
Only one takedown light turns on
• Check the connections from the light bar controller to the ROC
boards and ensure they are in the proper locations.
SignalMaster LEDs do not light
• Check the switch settings on the Serial Interface Module. Ensure
they are both set for the correct operation.
• Ensure that Switch 4 on SW2 is in the correct position for the
selected operation on the Serial Interface Module and ignition
power was removed and reapplied.
• Check the connections at the SignalMaster controller. If the
controller is a model SS2000SM, ensure that the connector has
power and the ground is connected to pins 10 and 11 on the
SignalMaster plug.
