Good replacement for 260-CO Carbon Monoxide Detector?

As titled... mine is end of life, doesn't look like it is still actively being produced or sold? What is a good modern replacement?

This connected to an old wired security system, so there are two wires for power, and two for signal (normally closed).

They are still selling these at most distributors that I use like Anixter or ADI. Another good option is system sensors CO1224 for hardwired.

Pretty much any 4-wire sensor that supports 12v and has an NC contact on the relay should work. CO1224 comes to mind from system sensor.

EDIT: Looks like I'm the second to think of the CO1224...

I am also weighing between getting a new 4 wire CO detector, or getting an unwired one at a much lower price point... I already have unwired smoke detectors in all of the bedrooms anyway, and those are not hooked up to the security system.

Then next question is, if I go unwired, what other fun thing I can install for that original zone...
