System Sensor (the recommend option) doesn't offer a conventional 2-wire CO so the CO1224T is the best option.
Ah - thank you for the help. Last question (hopefully) - is there a conventional 2-wire CO detector that you would recommend? Or just the 4-wire CO detector you listed below?
It looks like even the 4-wire version requires the use of an interface module. You can read the Installation Instructions for the device here: http://systemsensor.com/en-us/Documents/COSMO_Manual_I56-3747.pdf. For a conventional 4-wire CO detector, you could try this: https://www.alarmgrid.com/products/system-sensor-co1224t. The reason the COSMO devices require the interface is that they are both CO and Smoke detectors, so the COSMOD device separates this dual input into it's separate respective zone outputs, one for CO and one for Smoke.
Hi. Trying to stay with a wired CO detector for a Vista 21ip panel. Would you recommend the 4-wire COSMO-4W (https://www.alarmgrid.com/products/system-sensor-cosmo-4w) then? Will COSMO-4W interface directly to Vista panel without an interface module?
If you use this device, you would also need this: https://www.alarmgrid.com/products/system-sensor-cosmod2w to act as an interface between the CO detector and the panel. The Vista panels don't currently support a 2-wire CO detector without an interface module. If you only need one CO detector, you might be better off to go wireless, with the 5800CO (https://www.alarmgrid.com/products/honeywell-5800co).
Would you recommend this for a 2-wire carbon monoxide for the Vista-21ip system?
