Hi I am installing a accenta Gen 4 system .Its for a residential home for people with learning difficulties. Basiacllly they want the doors to chime and light up on the key pad until

reset or another door opens . So the light is on pretty much all the time regardless of the door then being shut I am thinking of installing your "Elmdene EN3 QFC Grade 3 flush contacts red resistor " I just want to know whether these are compatible with the system . Ie I am not going to install them then a fault comes up on the keypad

It is compatible but overkill IMO

JUst use the standard secware door contact.

 

However I dont think the panel work as you want in this application. Chime will stop when the circuit closes. You will need either a latching system with manual reset per door or a more powerful panel that can be programmed to work like this.
