Ray phillips 0 Posted June 30 Share Posted June 30 Hi all After some advice on an intercomm I was recently asked to change, only been doing them a year or so so still got a lot to learn. The old video intercomm a Genway 4 wire was being problematic so changed it for a similar 4 wire unit which is for a doctors surgery. Video & audio works fine just wont open the door when button pressed. On the Genway you could open the door from the handset but the new one wont work when button pressed on the internal staion. It's an auto door if that helps. On the Genway there was a 2nd output for the door cable on the back of the intercomm. Any guidance appreciated. Quote Link to post Share on other sites

Ray phillips 0 Posted June 30 Author Share Posted June 30 (edited) Forgot to upload pics Old unit was a 4 wire Genway, the door cables were connected to the back of the door station from a 2nd output which is the 2nd white connector block on rear panel photo. The new unit is a ccl which is also 4 wire with 2 black for connection to door lock. Also it is existing cabling video and audio work fine just door release having problems with.

james.wilson 741 Posted June 30 Share Posted June 30 i presume you need a clean switch to operate your auto door, is the output a switched 12v?

james.wilson 741 Posted June 30 Share Posted June 30 im not suprised your lucky you didnt damage something. ie the sliding door controller they arnt cheap You need to check whats on those black wires when, i dont have the manual in my hand. Id assume they are designed to go to a lock release not a door controller for a sliding door Quote securitywarehouse https://www.securitywarehouse.co.uk Trade Members please contact us for your TSI vetted trade discount.
