Light / Horn Independence: Light and horn can be controlled via separate relays

Power Requirement: No additional power required when installed in Helios. When mounted remote: 24 VDC

Transmitter Power Supply: The Helios’s internal transmitter power supply is downgraded from 200 mA when it powers the Light / Horn. To determine the total downgrade, add the currents for the light(s) being used and the horn if used. If more power is needed, then consider the PDA1024-01.
MOD-PD2LH and MOD-PD2LH5CB1 Models:
Example: 17 mA (Red Light) + 20 mA (Horn) = 37 mA total current downgrade from the 200 mA supply. Left over current = 163 mA

Color Downgraded by
Red 17mA
Green 15mA
Yellow 23mA
Blue 15mA
White 42mA
Horn 20mA
Downgraded by each color that is turned on and the horn.
Example: 33 mA (Yellow Light) + 38 mA (Horn) = 71 mA total current downgrade from the 200 mA supply. Left over current = 139 mA

Red 34mA
Green 29mA

Horn 38mA
