Is this a direct replacement for the CO/Propane alarm which comes in the 70-742 R kit? Mine is just over 5 years.
Replaced an older alarm with the sate-t-alert 70-742 R KIT (including shut off valve) just over 5 years ago. Would like to replace JUST the alarm portion if possible. Is this a direct replacement for just that alarm portion, and, is it recessed (not surface mount)? Thank you
