** System Sensor i4 CO and Smoke in one?

[Mp333]

Has anyone installed a System Sensor i4 CO and Smoke with ELK? Looking to replace couple 2wire smokes with these i4 CO and smoke.

They get installed in place of current smoke and there is a Module that gets installed near the M!G that deciphers the smoke and CO signals.
These apparently just came out.
Any other options?

For integrated fire/CO, it's the only option and brand new to the market.
 
The module is no different, per se, than a 2W-MOD2. You wire the fire as a 4 wire fire circuit so compatibility or listings of compatible detectors is a moot point.

All those LEDs on there, I cant believe they may have found a way to make them uglier than the i3 series!
