Potter CS-24W — ceiling-mount selectable-candela fire alarm strobe with white faceplate, Potter part number 4890021.
A ceiling strobe earns its place where wall space is taken or where coverage works out better from overhead. The CS Series ships on a 4" plate with the Super-Slide bracket, so the plate and field wiring go in at rough-in and the appliance locks on at trim-out with no visible screws. The Checkmate terminal block lets an installer read voltage at the device without pulling it off the bracket, and candela is set with tamperproof field switches.

Check the model before ordering: CHS-24W (4890041) is the ceiling horn/strobe, and the wall-mount S-24WW (4890011) is a different appliance whose candela table is 15/30/60/75/110 — its settings do not match this ceiling unit.
