Does the Westinghouse CO Sensor models have CO shutoff?

Last reviewed July 2026.

A system is advertised; no named standard stands behind it. Westinghouse sells parallel versions of several generators with and without a CO sensor — the "CO Sensor" suffix in the model name is the differentiator, which at least makes the choice visible at purchase. We could not locate a standard citation (G300/UL 2201) for the system (checked 2026-07-14). Buying tip that follows directly from the catalog structure: the non-sensor variant is usually a few dollars cheaper, and that is the whole difference.

How to read this

Two ANSI standards govern generator CO safety, and they are not equal claims: UL 2201 is third-party certified with a public listing (and per CPSC's modeling, machines built to it would avert nearly 100% of generator CO deaths); ANSI/PGMA G300 conformance is stated by the manufacturer (~87% in the same modeling). An advertised shutoff with no named standard is better than nothing and checkable against nothing. See the two standards compared — and remember a shutoff is not permission.

Generator Score indexes CO-shutoff systems against the two ANSI standards and the public record (UL listings, manufacturer citations, CPSC data), with attribution — we test nothing and give no safety advice. No CO-shutoff system makes a generator safe to run indoors, in a garage, or near openings — CPSC's placement guidance (outdoors only, 20+ feet from the home, exhaust pointed away) is the operative document, and a shutoff is a backstop for mistakes, not permission to make them. If a maker publishes a standard citation or a listing appears, the page changes — the record wins.
