What applications are suitable for IP69K products?

IP69K products are ideal for applications in Food and Beverage, Wastewater, Pharmaceutical, Marine, and Medical Facilities/Equipment Manufacturing.

How are IP69K products tested for water resistance?

Products are tested with high-pressure steam jet cleaning, water sprays of 1160–1450 psi from 4 angles, 4–6 inches distance, at 176°F (80°C).

How are IP69K products tested for dust protection?

Products are dust-tight tested in an Arizona A2 Dust chamber for 6 seconds at a time, every 15 minutes for five hours, at 2kg/m³.

What are the benefits of using IP69K rated products?

IP69K products help reduce product failures due to water/dust ingress, increasing productivity and decreasing production downtime.

What other certifications do Federal Signal products hold?

In addition to IP69K, Federal Signal products meet or exceed UL, CSA, CSFM, IECEx, and other global certifications, and are ISO 9001 Certified.

What is the IP69K rating?

What environments are IP69K products suitable for?

IP69K products are ideal for applications in Food and Beverage, Wastewater, Pharmaceutical, Marine, Medical Facilities, and Medical Equipment Manufacturing.

How is IP69K different from NEMA Type 4?

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

How to Install the 191XL Series LED Beacon

This guide provides step-by-step instructions for installing and wiring the 191XL Series LED Beacon in hazardous locations.

Estimated time: 45m

Tools needed:

Screwdriver, Wire strippers, Multimeter

Supplies needed:

Mounting screws, Terminal connectors, Conductive sealant

  1. Unpack and Inspect the Beacon

    Carefully unpack the beacon and inspect it for any damage that may have occurred during transit. Do not proceed with installation if the beacon is damaged.

  2. Mount the Beacon

    Choose a suitable location for the beacon. For pipe mounting, ensure the mating threads are clean, apply conductive sealant to the conduit threads, and secure the beacon to a 3/4" pipe using 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 the supplied hardware.

  3. Wiring the Beacon

    Ensure power is off before connecting wires. For 120-240 Vac models, connect the black lead to the hot side and the white lead to the neutral side of the power source. For 24 Vac/dc models, connect the red lead to the positive side and the black lead to the negative side. If applicable, connect the green/yellow lead to earth ground.

  4. Reconnect Power and Test

    After completing the wiring, ensure all connections are secure and the beacon is properly closed. Reconnect power to the beacon and test its operation to ensure it is functioning correctly.

  5. Calibrate the Beacon

    If necessary, change the beacon from Flash Mode to Steady Mode by disconnecting power, removing the dome assembly, and adjusting the jumper on the printed circuit board as per the instructions. Reassemble and test the beacon again.
