PDA3400 Series Enclosure with Light / Horn

PDA3400 Series Enclosure with Light / Horn

PDA3407 Enclosure Shown with a ProVu Meter and MOD-LH Light / Horn and Reset Button. Meter & MOD-LH Sold Separately. Assembly Required.

Light / Horn Accessories

Precision Digital offers the PDA-LH, a Light / Horn that can be mounted to the PDA3407 and PDA3408 by the user. This Light / Horn can be wired to flash or stay steady on and the horn is rated at 85 dB. The light and horn can be controlled independently of each other via separate relays on the meter / controller such that the horn can be programmed to silence via a button mounted to the enclosure and the light can be programmed to stay on until the alarm clears.

The light / horn and button are all rated NEMA 4X or IP65. The following table illustrates a typical way the Light / Horn accessory can be wired and programmed using the four relays on the ProVu meter:
