UltraFire ULLS10RF & ULLH10RF Product Support

Over time, the manufacturing processes and features of the UltraFire ULLS10RF and ULLH10RF smoke and heat alarms with wireless interlink have changed and improved, leading to differences between alarms and RF bases manufactured at different times. This page will help you identify which revision of alarms you have, directing you to the correct manuals and datasheets.

Please Note: The different revisions of the ULLS10RF and ULLH10RF alarms are not interlink-compatible with each other. If you have an existing interlink system of Rev.A models, you will need to replace all of them with Rev.B models to maintain an interlinked system. The physical design of the alarms and the RF base has not changed, so the new models will fit on the existing screw holes.
