How to wire two wire smokes to a Honeywell Vista 20P - Things you need to know

Jon takes you through short tutorial of how to wire 2 wire smoke detectors into a Honeywell Vista 20P alarm system. He'll explain why the zone he's using for this is the one and only zone for two wire smokes on the Vista 20P.
Two wire smoke detectors are handled differently than four wire smokes would be. Two wire smokes all get run on the same wire run. This way you'll know there's a fire. Four wire smokes can be cordoned out to other zones so you can tell exactly where a fire may have started. They do have things in common though such as they require a power source and a rest. We'll be doing a video specifically about four wire smokes soon™

thanks for that it was really good and help me

[@AlarmSystemStore]

Awesome! We are very glad to hear it helped. Have a great day!

Thank you for the video. I have a slight challenge. I have an ADT safewatch 3000 with 1, 2 wire smoke detector. I like to upgrade the 2 wire smoke detector to a smoke and carbon monoxide detector. However, I don’t know if I’m system will allow the upgrade nor which type of detector I should look for. I will also be adding 5 more detectors smoke and carbon, thanks to your video I’m good with that part. Thank you in advance

How do you tie in the cables if all the cables are home run back to the panel?

[@AlarmSystemStore]

Ideally you will need to create a parallel wire loop that "zig-zags" back and forth from each sensor to the panel with a resistor on the last smoke. Alternatively you can just connect them all to zone 1 , however, only one resistor can be used on zone 1, so only the smoke with the resistor will be supervised for faults if you do this.

[@1960buddies]

so if you use zone 1 say for a door contact with a EOLR that line will be a powered line? where zones 2-8 are just looking for continuity?

[@AlarmSystemStore]

All zones look for continuity. It's just that zone 1 provides power for 2 wire smokes

Is this the same if it were to be installed on a Vista 128?

[@sakriso]

I just installed a new Vista 20p with 5 smokes and after programming I'm getting a Fire Trouble 01 error. Not sure why. Any clues? The units I'm using are System Sensor 13 Series model 2W-B.

Where do I find the resister

[@AlarmSystemStore]

The Vista panels normally come with a pack of resistors that includes the 2.2K resistor for 2-wire smokes, but if you do not have all of the original equipment you will need to source it elsewhere. You can find them online pretty easily.
