Siemens HMS-SA (500-034150) Intelligent Manual Pull Station, Single Action with Auxiliary Contacts, Canada ULC Version

Siemens HMS-SA — addressable single-action manual pull station with a normally closed auxiliary contact, part number 500-034150, for FireFinder XLS.

It communicates both ways with the panel over the DLC loop, takes its address from the DPU programmer, and latches its lever down until reset with an Allen key. The extra contact releases door holders or magnetic locks. Siemens documents it on a Canadian data sheet (6316C, for Canada only) as ULC Listed and FM Approved.
