Rated 5 out of 5 by 3 reviewers.
Rated 5 out of 5 by Great price easy to use simple to use as an interconnect between residencal flow switch and smoke detectors Great product for the price April 4, 2015
Rated 5 out of 5 by Really hits the mark. I was getting ready to build my own circuit to connect my Hardwired Kidde smoke detectors to my wireless remote alarm system. This board detects the 9vdc signal on the red leg of the interconnect wiring without loading down the detectors and produces either a Normally Closed or Normally Open output. I used that output to activate a wireless door switch that had an aux input for a normally closed condition. Worked great. I was able to fit the circuit card inside the 3.5" round light fixture box that supports the Smoke detector. May 12, 2013
Rated 5 out of 5 by Easy To hook Up I hooked it up to my House alarm system. it was easy to install. It has normally open and normally closed contacts. It also has easy to understand wire schematics. Now I have all 5 of my smoke detectors hooked up my alarm system, instead of just one alarm smoke detector. March 11, 2012
