What is the IP69K rating?
IP69K is the highest standard on the Ingress Protection (IP) rating scale, designed for products regularly exposed to high-pressure and high-temperature washdowns.
What does IP69K protect against?
IP69K protects electrical devices against ingress of solids (dust-tight) and water, specifically from close-range, powerful, high-temperature water jets.
What applications are suitable for IP69K products?
IP69K products are ideal for applications in Food and Beverage, Wastewater, Pharmaceutical, Marine, Medical Facilities, and Medical Equipment Manufacturing.
What type of product is the 151XST?
The 151XST is a Hazardous Location Strobe Light.
What are the IP69K testing conditions?
Products are dust-tight tested in an Arizona A2 Dust chamber and undergo high-pressure steam jet cleaning with water sprays of 1160–1450 psi at 176°F (80°C) from 4-6 inches.
What other certifications do Federal Signal products have?
Federal Signal products meet or exceed standards of UL, CSA, CSFM, IECEx, and other global certifications, and are ISO 9001 Certified.
How does IP69K differ from NEMA Type 4?
IP69K involves high-pressure, high-temperature water jets at short distances (6 inches max), while NEMA Type 4 involves high volume water at long distances (10–12 feet).
What is the benefit of IP69K products?
IP69K products help reduce product failures due to water/dust ingress, increasing productivity and decreasing production downtime.
What is the IP69K rating?
IP69K is the highest standard on the Ingress Protection (IP) rating scale, designed for products regularly exposed to high-pressure and high-temperature washdowns.
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 to Install the 151XST-240C Strobe Light
This guide provides step-by-step instructions for installing and wiring the 151XST-240C strobe light in hazardous conditions.
Estimated time: 45m
Tools needed:
Screwdriver, Wire strippers, Multimeter
Supplies needed:
Mounting screws, Terminal connectors, Conductive sealant
- 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.
- Mount the Strobe Light
Choose a suitable location for mounting. For pipe mounting, ensure threads are clean, apply conductive sealant to the threads, and secure the light to a 3/4-inch NPT pipe using the set screw. For surface mounting, use the mounting base as a template to mark and drill holes, then secure the light with installer-supplied hardware.
- 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. If necessary, connect the green screw to an earth ground. Replace the dome assembly securely.
- Test the Strobe Light
After wiring, restore power to the strobe light and test it to ensure proper operation. Verify that the light flashes as expected.
