How to Install the 151XST Strobe Light

This guide provides step-by-step instructions for installing and wiring the 151XST 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 shipping. If damaged, do not install and file a claim with the carrier.

  2. Mount the Strobe Light

    For pipe mounting, clean the mating threads and apply conductive sealant to the conduit threads. Thread the fixture onto a 3/4-inch NPT pipe and secure it with the set screw. For surface mounting, use the mounting base as a template to mark and drill two 9/32-inch holes, then secure the beacon with installer-supplied hardware.

  3. Wire the Strobe Light

    Ensure power is off before connecting wires. 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. If necessary, connect the green screw to an earth ground.

  4. Secure the Dome Assembly

    After wiring, secure the dome assembly back onto the strobe light by twisting it clockwise until it is firmly in place.

  5. Test the Strobe Light

    Reconnect power to the strobe light and test it to ensure it is operating properly. Verify that the light flashes as expected.
