 3840GCPE FLASHER
Owner's Manual
GENERAL
The heavy duty 3840GCPE electronic flasher has been designed to operate in the most severe environments. This
unit has been designed to comply with the Federal specification for Ambulances KKK-A-1822E. The unit has output
short circuit protection for reverse input voltage protection. This flasher is designed to be operated manually in either
the Primary or Secondary mode. Primary Mode is standard running mode, which alternately flashes the A warning
lights with the B & C warning lights. All lamps operate at full power when in the Primary Mode. The Secondary Mode
is normally set at the scene and alternately flashes the A warning lights with the B warning lights at full power, with C
lights off.
WARNING LIGHTS
The 3840GCPE flasher can be used with most incandescent, halogen, and LED warning lights.
CHARACTERISTICS & TIPS
1) For extended service reliability, it is important that the flasher is not overloaded. In some
cases the unit's short circuit protection may consider the overload a short circuit, and shut
the unit down.
2) If the Primary and Secondary terminals are both grounded, the flasher will operate in Primary Mode.
SPECIFICATIONS
Maximum output current:
Terminal A - 30 Amps; Terminal B - 30 Amps; Terminal C - 30 Amps

Customer supplied overload protection must be in series with +12Vdc
input, and should be 25% greater than either all A lights, or all B & C
lights, whichever is larger.
TROUBLESHOOTING
PROBLEM
ITEMS TO CHECK
All outputs do not flash:
1) Is the battery voltage less than 10Vdc?
2) Are the wire and light connections proper?
3) Do you have more than the rated number of
lights on the outputs?
4) Is the remote ground switch wired correctly?
One output does not flash:
1) Is the battery voltage less than 10 Vdc?
2) Is the affected output shorted or overloaded?
3) Are the wire and light connections proper?
