Some systems may require even greater back-up capabilities. Standard sprinklers are available in temperature ranges of 57 o to 182 o C. Other temperature ranges are available but are specially made to suit. Home smoke alarms are designed for domestic use and are manufactured accordingly. Commercial grade smoke detectors are designed and manufactured to a higher standard than the domestic ones. The Uniform Building Code of Australia, known as the BCA set the criteria for the requirements of such a system.
Sprinkler systems use a dedicated mains supply to provide adequate water for the system.
A set of control valves control the flow and also provide the signal to the fire brigade of any fire. A fire detection system divides a building into areas or zones. These zones contain many detection devices which can raise an alarm on the fire indicating panel. The panel can display from what area or zone the alarm originates, and hence provide a location for the fire fighting teams to attend. A conventional system connects many devices on the zone together.
