Went to buy some smokes from alarm supply house other day and along with the smokes I picked up the reversing relay that makes them all sound on the line if any single unit activates . Makes sense want to wake the house up right? Counter guy tells me congratulations your one of the only dealers who buys the relay when you purchase the smokes. He then asks why are others not buying it and how are they installing the smokes to work properly good ? either they are not using them at all and allowing one smoke activated sound or they are using a cheaper burg relay to do it a very dangerous choice. In either case how are they getting this by AHJ if there being used for primary service?
I say it shows installer and alarm dealer ignorance and lack of education or outright greed by not using it one more dollars profit.. What do you think?
