Maximize Compliance and Market Reach: A Guide to UL vs. ETL Certification and Multi-Listing

By Andrew Erickson

March 21, 2025

If you're installing a new fire alarm system or expanding your product offerings in the fire safety market, there's no question that certification matters.

Due to sheer popularity, it's easy to assume that "UL" is the only recognized mark for fire alarm devices. The truth is, "ETL" is another valid option and meets the same standards.

In this guide, we'll uncover the differences between UL and ETL certifications, explain what Multi-Listing (ML) really means, and show you how to leverage it to expand your offerings without sacrificing compliance or performance. Let's get started!

UL- vs ETL-Listings

Fire Alarm Certification is Mandatory

Certification isn't just a regulatory checkbox. It's your front-line defense against system failures when lives and property are at risk. Fire alarm certifications mean the equipment meets:

  • Emergency Performance Expectations - Certified equipment undergoes rigorous testing to ensure it functions reliably during a fire.
  • Legal Requirements - In many jurisdictions, uncertified fire alarm equipment is not legally approved for installation and could invalidate insurance coverage.
  • Reputation & Liability Standards - If a fire alarm system fails during an emergency, the legal and financial consequences can be devastating for manufacturers, installers, and building owners alike.

Whether you choose UL or ETL, the proper certification confirms that a device meets the industry's very detailed safety and performance standards.

Understand UL 864 and Its Role in Fire Alarm Systems

When someone says "UL fire alarm certification," they're typically talking about UL 864. This standard covers a range of fire alarm system components - including control panels and sensors - to make sure they stand up to real-world hazards.

  • Core Standard - UL 864 outlines how fire alarm devices must perform under various conditions.
  • Industry Benchmark - Both UL and ETL test to UL 864 guidelines for fire detection and signaling.
  • Not Just a Label - If a product is listed under UL 864 (whether tested through UL or ETL), you'll know it meets the same essential requirements.

The UL 864 standard is the real thing that matters. Whether a device carries the UL or ETL label, it has passed the same tests. When you use gear certified against the UL 864 standard, you know you have a proven solution.

ETL vs UL Certifications in Fire Alarm Markets

Historically, UL has been the dominant name in fire safety. But ETL, administered by Intertek, is also widely accepted - and often more cost-effective for manufacturers who can than pass savings on to you. When needing to select between the two, consider:

  • Brand Recognition: UL has strong name recognition due to its long history.
  • Speed & Cost: ETL certification can be faster and more affordable.
  • Acceptance: Most jurisdictions accept ETL as meeting the same standards as UL.

For companies exporting equipment outside their own country, ETL certification is an increasingly popular option.

The Role of Multi-Listing in Fire Alarm Equipment

Multi-Listing (ML) is a very useful way for fire alarm equipment manufacturers or distributors to sell a product under multiple brand names while retaining the original certification. Think of it like private labeling - except you also get to keep the safety credentials.

Common reasons for Multi-Listing equipment include:

  1. Private Labeling - You can offer an existing product under a new brand.
  2. Market Expansion - You're able to partner with resellers to reach more customers.
  3. Regulatory Compliance - You'll keep your equipment compliant under different names without requiring repeated testing.

If you're looking to rebrand a UL- or ETL-listed device - such as an FACP, smoke detector, or suppression system - under your own company label, Multi-Listing is an efficient way to do it.

UL vs. ETL Multi-Listing: What's the Difference?

When a fire alarm equipment supplier recently asked about Digitize's gear for Multi-Listing, the conversation boiled down to one very simple question: "Is your equipment UL-listed?"

Naturally, our answer had to be fairly detailed, since it is functionally a "yes" in just about every case.

Digitize's equipment is ETL-listed, which is functionally equivalent to UL - but managed by a different certification body.

Feature UL Multi-Listing ETL Multi-Listing
Certification Body Underwriters Laboratories (UL) Intertek (ETL)
Standards Compliance Meets UL standards (e.g., UL 864) Meets the same standards via Intertek
Multi-Listing Process Managed by UL Managed by Intertek
Cross-Certification? No, UL-listed products stay under UL's program No, ETL-listed products stay under ETL's program
Market Recognition UL has strong brand recognition ETL is widely accepted and meets same standards

It's true that UL- and ETL-listings are very similar. However, it's important to note that a device can't be both an ETL-listed product and be part of UL's Multi-Listing program - and vice versa. This is because these programs are administered separately.

Will ETL Certification Work for You?

If you're used to seeing only the UL mark, you may wonder whether ETL is acceptable in your market. In most cases, the answer is "yes."

  • Same Safety Standards - ETL follows UL 864, NFPA, and NEC guidelines.
  • Wide Regulatory Acceptance - Many building codes recognize ETL as a valid alternative to UL.
  • Easy Multi-Listing - ETL manages its own Multi-Listing process, so you can rebrand an ETL-listed device without repeating the same tests.

Remember, it's always best to confirm local requirements, as some projects or AHJs (Authorities Having Jurisdiction) may specify "UL" explicitly.

How to Multi-List Fire Alarm Equipment

The Multi-Listing process typically involves several steps:

  1. Confirm Certification - Determine if the original product is UL- or ETL-listed.
  2. Request Multi-Listing - The manufacturer submits a formal request to UL or Intertek.
  3. Verification - The certification body checks that the product still meets compliance standards.
  4. Rebranding & Labeling - The device receives a new name and model number under the reseller's brand.
  5. Ongoing Compliance - Expect regular audits to maintain the listing.

This process makes sure you maintain the original certification while tailoring the product to your brand.

Multi-Listing Benefits Distributors and OEMs

Multi-Listing isn't just about compliance. It also offers a competitive advantage for fire alarm distributors and original equipment manufacturers (OEMs).

For Distributors

  • Private Branding - Sell a proven system under your own label.
  • Expand Portfolio - Add fire alarm products quickly, without extensive R&D and new-device certification.
  • Preserve Compliance - No need to re-test if the original certification is valid.

For Manufacturers

  • Market Reach - Partner with multiple private-label distributors to increase your sales.
  • Streamlined Approach - Avoid juggling multiple independent certifications.
  • Cost Savings - Use existing approvals for multiple brands.

If you want to increase your market share with less time and expense, Multi-Listing is a "no-brainer".

Check if Your Fire Alarm Product Is UL or ETL Certified

Before purchasing - or Multi-Listing - fire alarm equipment, do some quick research to be sure you know all the necessary details. To determine whether the equipment is UL or ETL certified, make sure you check:

  1. Online Directories - UL and Intertek maintain searchable databases by manufacturer or model.
  2. Product Labeling - UL-listed products carry the UL mark; ETL-listed devices show the ETL mark.
  3. Certification Docs - Always request official documentation from the manufacturer.
  4. Local AHJ Requirements - Some jurisdictions might have a preference for UL or ETL. Confirm acceptance before you buy.

Doing a little research upfront makes sure your device (and your project) is on solid legal and safety ground.

Can a Fire Alarm System Be Both UL and ETL Listed?

Technically, yes. It's possible to hold both certifications - but it means going through two separate processes and paying two sets of fees.

  • Separate Testing - Each organization requires its own compliance checks.
  • Dual Maintenance - You'll need ongoing inspections and documentation for each certification body.
  • Cost vs. Benefit - If you serve multiple markets with differing requirements, dual certification might make sense. Otherwise, most companies simply stick to one.

Unless your specific project requires both labels, choosing UL or ETL is usually enough.

Fire Alarm Certification Impacts Insurance and Liability

Insurance companies and AHJs keep a close eye on fire alarm certifications since they impact:

  • Insurance Compliance - Most commercial policies require UL or ETL certification. If a non-listed device fails during a fire, expect a battle over coverage.
  • Legal Liability - Proper certification helps protect manufacturers, installers, and building owners if something goes wrong.
  • Code Enforcement - Using non-certified equipment can lead to fines or rejection during fire inspections.

A recognized certification is a must-have for both financial and legal protection.

How to Choose the Right Fire Alarm Monitoring Equipment

Certification is important, but it's not the whole story. Your fire alarm monitoring system should also deliver:

  • Scalability - Support multiple panels, remote sites, or large commercial facilities.
  • Compatibility - Easily integrate with existing fire protection systems.
  • Standards Compliance - UL 864, NFPA 72, and local building codes.
  • Flexible Communication - IP, cellular, radio, and hardwired options.
  • User-Friendly Interfaces - Centralized monitoring software or a web interface.
