System Sensor COSMOD2W and COSMOD4W wiring and programing tutorial for Honeywell Vista alarm systems

This video cut hours off my day. Keep up the great work. Thank you!

You're welcome!

nice video, thanks! one question though: what's the benefit of using the 4 wire version over the 2 wire version? why not just use the 2 wire?

[@AlarmSystemStore]

For new installs the 2-wire is generally the better choice, but I believe the 4-wire option exists to include existing 4W smoke detectors.

I don’t know a lot about the wiring, but trying to figure it out because my security company decided they don’t want to support crossing over my existing 4w to their monitoring. At the beginning, you were explaining the need for the 4204 relay, and you said “if you are using trigger 17.” Probably some ignorance here, but I didn’t see you hook up to output 17, which I thought was the far left of the 8 pin connector.. what am I misunderstanding here? Additionally, are you saying that if you aren’t using that output, you can go without the relay? What would the alternative be? And I’m guessing there is a good reason to use output 17, what’s that? For help with my question, I have the cosmod, 3 cosmo4w combos, and 5 4wtb smokes. Previously, the system was only 6 4w smokes and I think connected through output 17 and zone 2 only.. the security company cut most of the stuff from the panel, removed its power, and used a cross over wireless to utilize my wired window and door sensors. Now I’m needing to add power back to the vista panel and set up only smoke and co zones. I think I can do it just like in this video, and thanks so much for it, but I was just curious if the above. There is a lot going on in the Honeywell box right now, all most unhooked (previous monitoring services and other modules that I don’t know what they do)..

The techs shooting the vids rarely check in on the vids beyond the first month or so of posting. I can and often do answer many questions on here the channel, but I am not as up to par on the finer details on the Vista system programming in particular. I'd recommend you submit a support ticket on the website for this.

I was really hoping for an explanation why you use the cosmod and it’s intended purpose !

[@AlarmSystemStore]

Well like the title states, this is a technical tutorial video. It is assumed those watching would know what it is and it's purpose.

I have recently replaced the CO2 sensors (CO-REPL) in 8 COSMO-2Ws. Since replacing them, the system has been in a constant Trouble/Trouble Restore cycle. All the zone faults are for the CO2 zone. I've rebooted (complete power down) and cleared faults multiple times, all to no avail. Can anyone provide some direction?

Do you know of any security systems that use a digital packet method of communications between the sensors and the panel as opposed to analog wired sensors?

you could try the Honeywell vista panels and 5800 series devices. you will need a wireless transceiver for the devices.
