GENERAL
WARNING LIGHTS
The 3860GCPE flasher can be used with most incandescent, halogen, and LED warning lights.
CHARACTERISTICS & TIPS
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.
If the Primary and Secondary terminals are both grounded, the flasher will operate in Primary Mode.

3860GCPE FLASHER
Owner's Manual
2)
1)
The 3860GCPE electronic flasher has been designed to operate in the most severe environments. This heavy duty
flasher has been designed and certified to Federal specification for Ambulances KKK-A-1822E. The flasher has output
short circuit protection and reverse input voltage protection. This unit 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. The Secondary Mode is normally used at the scene and alternately flashes the A warning
lights with the B warning lights, with C lights off. All lamps operate at full power when in either mode.
Maximum output current:
Terminal A: 40 Amps (typically eight 60W Lamps)
Terminal B: 24 Amps (typically four 60W Lamps)
Terminal C: 30 Amps (typically six 60W Lamps)
Input Voltage:
10-16 Vdc, 13.6 Vdc nominal
Flash Rate:
75-80 per minute at 50% duty cycle
Ambient temperature:
-40ºF to +150ºF (-40ºC to +65ºC)
Fuse or Circuit Breaker
70 Amps max.
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.
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?
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?
