Yes, the MTI 35-742-BL is compatible as a replacement for the Safe-T-Alert 30-742, provided your existing 30-742 is the flush-mount 12V hardwired combination Propane (LP) and Carbon Monoxide (CO) alarm.
The 35-742-BL:
- Detects both propane (LP) and carbon monoxide (CO).
- Is a 12V DC hardwired, flush-mount unit.
- Is the current-generation Safe-T-Alert combination alarm from MTI
