It is also sadden that many Deaf people don't have that luxury of safety that hearing people have. How many of you can afford these carbon monoxide alarm that has transmitter for Deaf? Don't forget CO2 alarm needs to be replaced between 5 and 10 years depending on manufacturer specs. None of these alarms for Deaf will work during power outrage unless you add back up UPS on it.
I have integrated alarm system, everything is tied up including carbon monoxide alarm and smoke alarm. The only problem that I have is when power goes out, so is the alarm system. Sucks!
And only idiots would run any Internal combustion engine indoor without proper and sufficient ventilation.
