ul 217 approved with t3 pattern

Community Member

Does anyone know of Nest Protect Gen 2 is ul 217 approved with t3 pattern?  I'm trying to find a bed shaker/light for my mother who is hearing impaired and can't hear most smoke detectors. I found one that listens for ul 217 approved with t3 pattern, I know it's ul 217 compliant, but I can't find much about t3 pattern.

It's compatible with my alarm system's smoke monitoring system, which is also looking for a T3 pattern. So I'd say yes, it's compatible with the bed shaker. There are beeps before/after the spoken part of the Nest warning.
