Frequently Asked Questions

What is the IP69K rating?

IP69K is the highest standard on the Ingress Protection (IP) rating scale, designed for products exposed to high-pressure and high-temperature washdowns.

What does IP69K protect against?

IP69K ensures protection against close-range, powerful, high-temperature water jets and prevents ingress of dust.

What are IP69K testing conditions?

Products are dust-tight tested for five hours and subjected to high-pressure steam jet cleaning at 1160–1450 psi from 4–6 inches at 176°F (80°C).

What applications are suitable for IP69K products?

IP69K products are ideal for food and beverage, wastewater, pharmaceutical, marine, medical facilities, and medical equipment manufacturing.

How does IP69K differ from NEMA Type 4?

IP69K involves low volume, high temperature, high pressure water jets at short distances (6 inches max), while NEMA Type 4 involves high volume, low pressure water at long distances (10–12 feet).

What certifications do Federal Signal products meet?

Federal Signal products are designed to meet or exceed UL, CSA, CSFM, IECEx, and other global certifications, and the company is ISO 9001 Certified.

What is the 371DST-240C product type?

The 371DST is a Commander® Double Strobe Hazardous Location Light.

What is the purpose of IP ratings?

IP ratings classify and define levels of ingress protection on electrical devices against solids and water, ensuring specific coverage levels.

Does Federal Signal offer many IP69K products?

Yes, Federal Signal offers over 700 models of IP69K products for safe area, hazardous, and explosion-proof applications.

What is the benefit of IP69K products?

How to Install the 371DST Strobe Light

This guide provides step-by-step instructions for installing and wiring the 371DST Strobe Light in hazardous locations.

Estimated time: 45m

Tools needed:

Screwdriver, Wire strippers, Drill, Multimeter

Supplies needed:

Mounting screws, Terminal connectors, 1” NPT conduit hub (user-supplied), 1” NPT close-up plug (user-supplied)

  1. Unpack and Inspect the Light

    Carefully unpack the 371DST 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 Light

    Choose a flat horizontal surface or a 1” NPT pipe for mounting. For surface mounting, use the gasket as a template to mark and drill four 9/32” holes for screws and one 1-3/8” hole for wire entry. Secure the light using the provided screws and washers.

  3. Make Electrical Connections

    Disconnect power before proceeding. Remove the dome assembly by turning the die-cast ring counter-clockwise. Route the supply wires into the housing, strip 0.28” of insulation from the ends, and connect them to the terminal block, ensuring proper polarity for DC models. Connect the earth ground to the terminal block.

  4. Reassemble and Test the Light

    Reassemble the light by securing the dome assembly back in place. Turn on the power and test the light to ensure it operates correctly. Verify that the threaded dome ring joint is fully engaged.
