Battery back up is fine an dandy with the following exception. Visual smoke alarms used for the hearing impaired, either hard wired or on supply cord, current battery sources will not engage the flashing strobe light. Kind of a catch 22 there. The battery will sound the horn and thats about it, no flash, no warning for the deaf. One would think though with all of the new battery advances in the Nicad supplies that a flash system could be established along the lines like a camera flash. This is where Gentex, Kidde and the rest of the alarm mfg's really need to get on the ball. Thanks for the opportunity to rant a bit.

I do it to leave a spare in the attic.

Strobe should be easy with LED.

[Paul W. Abernathy]

Now i have put all the smokes on a single bedroom....NEC does not care either way so i have done both.

[Paul Sabados]

I dont think LED is going to cut it. 177 candela rating (UL 1971) on the strobes. LED would be comparable to a penlight next to a lightning bolt hitting in the backyard at night.

You ever try to stare at an LED directly?
I get your point though.

that true myself i am hard of hearing and i know how this situation going on with the resdental smoke alarm is.

but i belive they can really improve the techolgy with this example the back up battery they used in the flourscent luminaires are very small and with little design change it will work to run the powerfull strobe light easly.

but only one weak link is some deaf peoples are very sound sleeper they will need a bed viberator to wake them up so sorta like remote sender with reciver to let them know [ ATM i know someone did make that kind of smoke alarm with this i will post it later ]

Merci, Marc

Paul,..
I will provide the link to the device what you are describing and for other readers here i am sure you will see one way how the deaf peoples deal with this.

http://www.harriscomm.com/catalog/de...7a61d320cb86f8

this link will go to the smoke alarm page and it will show the listing of devices what many deaf peoples useing.

sorry to get somehow offtopic but related to this.
