Hi, I have an als dsc 585 which I have only 1 sensor connected in zone 1. the problem is that I have the system light on and the zone 3 and 4 light always. My doubt is that from what I saw I have to cancel the zones I do not use with co resistance. A zone to cancel how much resistance I have to buy

If you do not use resistance, they are canceled by programming. In section 001 goes 01 00 00 00 ##; for example.
