How to Install the 151XST Series Strobe Light

This guide provides step-by-step instructions for installing and wiring the 151XST Series Strobe Light in hazardous conditions.

Estimated time: 45m

Tools needed:

Screwdriver, Wire strippers, Multimeter

Supplies needed:

Mounting screws, Terminal connectors, Conductive sealant

  1. Unpack and Inspect the Strobe Light

    Carefully unpack the strobe light and inspect it for any damage that may have occurred during transit. If damaged, do not install and file a claim with the carrier.

  2. Mount the Strobe Light

    For pipe mounting, ensure the mating threads are clean, apply conductive sealant to the conduit threads, and thread the fixture onto a 3/4-inch pipe, securing it with the set screw. For surface mounting, use the mounting base as a template to mark and drill holes, then secure the beacon with installer-supplied hardware.

  3. Wire the Strobe Light

    Ensure power is off before wiring. For AC models, connect the black lead to the hot side and the white lead to the neutral side of the power source. For DC models, connect the red lead to the positive side and the black lead to the negative side. Secure the dome assembly back onto the base.

  4. Test the Strobe Light

    Once the wiring is complete, restore power to the beacon and test it to ensure it operates correctly. Verify that the light flashes as expected.
