Fire Alarm and Fire Installation Inspections: Legal Intervals

Fire alarm and fire installation inspections mean verifying the detection-announcement system (detector, panel, voice) and the extinguishing-water installation (hydrant, sprinkler, pump set) at least once a year with the proofs the regulation prescribes. Early alarm buys minutes; a ready fire installation decides the outcome of the intervention. Both systems degrade silently in operation: a strapped zone, a dried pump seal, a dusted detector — all reveal themselves only in the real fire.

Legal Frame and Intervals

The Regulation on Protection Against Fire in Buildings requires conformity to the project and annual periodic control; the fire clearance and occupancy permit processes depend on these reports. The practical calendar: yearly function scenario on detection, yearly staged pump trial (jockey-electric-diesel), pressure-flow control on the hydrant line, endpoint and alarm valve trials on sprinklers; plus the operator monthly visual and test-button discipline. Detailed audit: fire detection and alarm system inspection.

Steps of the Control

• Detection side: every zone detector triggered with a test device; panel record, alarm location, battery duration and mains-cut trial verified; strapped zones and fault log read.
• Alarm-announcement: siren sound level, announcement intelligibility and evacuation scenario measured; integration with the extinguishing system inspection tried.
• Pump-hydrant: suction supply, pressure-flow characteristic, gauge-hydrophore, cabinet-hose-nozzle integrity and frost protection; outdoor hydrant cap torque and flow.
• Sprinkler: valve positions, head cleanliness, last station flow switch, spare head stock.

Frequent Non-Conformities

On the installation side our fire detection and alarm systems and fire-water contracting works, on the audit side the yearly inspection programme are at hand. Prepare during the control, not when the alarm sounds.
