Fire Alarm System - Zoning

Zoning

An important consideration when designing fire alarms is that of individual zones. Specifically:

• A single zone should not exceed 2,000m² in floor space.
• Where addressable systems are in place, two faults should not remove protection from an area greater than 10,000m².
• A building may be viewed as a single zone if the floor space is less than 300m².
• Where the floor space exceeds 300m² then all zones should be restricted to a single floor level.
• Stairwells, lift shafts or other vertical shafts (non stop risers) within a single fire compartment should be considered as one or more separate zones.
• The maximum distance traveled within a zone to locate the fire should not exceed 60m.
