Frequently Asked Questions

What type of product is the Model 371DST?

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

What does the IP69K rating mean for this product?

The IP69K rating is the highest standard for ingress protection, designed for products exposed to high-pressure and high-temperature washdowns. It ensures protection against powerful water jets and dust ingress.

What environments are suitable for IP69K products?

IP69K products are ideal for applications in food and beverage, wastewater, pharmaceutical, marine, medical facilities, and medical equipment manufacturing where sanitation is required.

What tests do IP69K products undergo?

IP69K products are dust-tight tested in an Arizona A2 Dust chamber for five hours. They also endure high-pressure steam jet cleaning from 4 angles at 4–6 inches and 176°F (80°C).

How does IP69K differ from NEMA Type 4?

IP69K protects from close-range, powerful, high-temperature water jets and is dust-tight. NEMA Type 4 protects from high-volume water at long distances and is also dust-tight.

What certifications do Federal Signal IP69K products hold?

Federal Signal IP69K products meet or exceed UL, CSA, CSFM, IECEx, and other global certifications. The company is also ISO 9001 Certified.

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, 1” NPT close-up plug

  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 four drill positions. Drill three 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

    Disassemble the light by removing the dome assembly and the strobe-spinning assembly. Route the supply wires (10 AWG to 16 AWG) into the housing. Strip 0.28” of insulation from the wire ends and connect them to the terminal block, ensuring to observe polarity for DC models. Connect the earth ground to the terminal block.

  4. Reassemble and Test the Light

    Reassemble the light by securing the strobe-spinning assembly and dome. Ensure the threaded dome ring joint is fully engaged. Turn on the power and test the light to ensure it operates correctly.

  5. Establish Maintenance Procedures

    After installation, provide a copy of the instruction sheet to all operating personnel and establish a routine check procedure to ensure the light installation remains intact and operational.
