ULC Compatibility Index

You'll be prompted to either "save as" or "open" a Microsoft® Excel document.
Please read our Terms of Use!

Note: It is important to note that the panel manufacturer (in Canada) must list compatible smoke detectors. Using a non-compliant smoke detector with any ULC® Listed fire alarm control invalidates its certification and could place the building occupants at risk. If you have questions regarding compatibility of a particular smoke detector (not shown on the list), please contact the manufacturer.
