When designing fire alarm systems it is important that the fire alarm installer ensures that the spacing between the detectors comply with BS5839.
Positioning of Smoke and Heat Detectors
All smoke detectors have similar spacing requirements, but this can vary according to whether the detector is installer in an open plan environment or a narrow corridor. Heat detectors also all have similar spacing requirements although these are different to smoke detectors.
According to BS5839 the fire code for fire systems design, detectors for general areas the spacing between any point in a protected area and the detector nearest to that point should not exceed 7.5m for a smoke detector and 5.3m for a heat detector.
This BS5839 code is the cornerstone of fire system distribution and layout. Our new Commercial Fire Alarm system from Discount Fire Supplies also appears to this.
