Short answer: the Polish Interior Minister's regulation of 7 June 2010 on fire protection of buildings, other structures and sites classes as fire protection devices not only extinguishing systems and hydrants but also, among others, fire alarm systems, voice alarm systems, smoke control, fire doors and gates with closing devices, emergency escape lighting and the fire power cut-off switch. All of them undergo technical inspections and maintenance according to Polish Standards, technical documentation and the manufacturer's instructions, at intervals the manufacturer sets but at least once a year (§ 3(3) of the regulation).
For emergency and escape lighting the details come from EN 50172: a short functional test on simulated mains failure is usually done monthly, and a full-duration battery test (most often one hour) annually. Results are recorded in a log book. EN 1838 sets photometric requirements, including minimum illuminance on escape routes. Self-testing systems run these tests automatically, but results must still be read and documented.
The fire power cut-off switch disconnects the building supply except circuits of devices that must operate during a fire. The regulation requires it to be located near the main entrance or service connection and marked. The annual inspection covers operation, signage and accessibility and is confirmed by a report. Fire alarm, smoke control and fire door systems are serviced by companies qualified as the system manufacturer requires — the site tracks the schedule and reports.
External hydrants and the fire water supply have additional requirements under the Polish regulation on fire water supply and fire access roads: periodic flow and pressure testing and keeping access routes clear for fire crews. Maintenance of indoor hydrants is detailed in EN 671-3.
