The fire protection system (1) involves a central reporting unit (2) which gives an alarm. Signals from wireless fire detectors (6) are received by repeaters (4) and relays them to the central reporting unit. Also linked to repeaters are other types of detectors (8), handheld reporting units (10) and indicator lamps (12). The central reporting unit is also linked to display screens (14). |
