What is Relay? (Not VRS)
Nevermind the Video Relay Service. it is not what I am referring to, what I am referring to is a devices called Relay, or Relay contacts. This is what I used to tied up with most of my house light switch (3 way switch is required) and have the coil on relay tied to smoke and CO alarms.
Its really sadden me that most CO alarm manufacturers refused to make such important accommodation for the Deaf and took many Deafies lives away like LuciaDistrub that we know from here.
The picture is almost exact what I have, without the circuit board. Each blue device control one 3-way switch. The purpose of this is to make it work EVEN when the light switch is in "Off" position. I also hate strobes with passion. I somewhat lost my mind when strobes light kicks in and cause short term confusion. I grew up in Deaf School where they used flood light as alarm instead of strobe. They changed to strobes after I left Deaf School.
Now, tell me how many Deafies who owns home have such devices like these? Maybe very few of them. I am not here to brag, but to educate anyone, and in hope to have these ignorant manufacturers checked my comment and realize the need of such accommodation.
I refused wired 120V on doorbell button, too dangerous that way. I used whats called no voltage relay coil, they used grounding to detect on and off position on doorbell button so there is no shocking hazard. I had confused building inspector when I installed wood burning stove. He never heard of such system that I built and was very impressed on how much safety I put in. He send me letter certify my installation as "Beyond minimum safety requirement" In other word it means that its much safer than whats required by law.
Again, here I do not tolerate any insults or ignorant from anyone. I only welcome education and respect of safety.
