This detector-type is commonly found on the following Siemens – Fire Safety fire alarm control panels: TXR-320, System 3 and SXL. Model OP121 contains a magnet-test feature, and has optional relay and sounder bases.
Model OP121 is UL 268, ULC S529 Listed, as well as Factory Mutual (FM) and California State Fire Marshals’ (CSFM) Approved.
