The Apollo 55000-227USA is a Series 65A ionization smoke detector built around a twin compensating ionization chamber that holds its sensitivity steady as the chamber slowly accumulates dust and airborne contamination over its service life. It plugs into an Apollo Series 65 detector base wired onto a conventional two-wire fire alarm zone, drawing its alarm current through the panel's own detection circuit instead of a separate power wire, and it is listed as the direct replacement for Apollo's earlier 55000-250 Series 60A ionization detector.

- Twin compensating ionization chamber for stable long-term sensitivity
- Direct plug-in replacement for the discontinued Apollo 55000-250 detector

- LED alarm indicator visible from the detector base
Technical Specifications
