MOD-PD2LH Series PD2 & PD4 Light/Horn Modification

The Helios can be provided with an optional light(s) with built-in 85 dB horn that comes mounted and wired to the instrument or as separate items to be mounted as the user desires. Meter is sold separately. 

The MOD-PD2LH Series is available in three different light configurations. The first option is a factory ordered Light / Horn with a color of either red, green, yellow, blue, or white. 

The second option is a Light / Horn the user determines the light color (red, green, yellow, blue or white) by connecting the appropriate wire. 

The third option is a Light / Horn with red, yellow, and green layers the user can turn on independently.

The MOD-PD2LH can be powered from the Helios’s 200 mA transmitter power supply with enough power left over to drive most transmitters.

The light(s) and horn can be controlled independently of each other via separate relays on the Helios. 

These relays can be programmed for automatic or manual reset action to satisfy a wide variety of audible and visual alarm applications. The light can be programmed to flash (not available on MOD-PD2LH5CB1) or stay steady-on.

The Light / Horn and Reset Button do not affect the Helios’s NEMA 4X rating, but do void its UL approval.
