An Installation Control Valve or ICV for short, is a set of isolation valves which control a Fire Sprinkler System. An ICV will normally include an isolation valve below an alarm valve as well as above the alarm valve. An alarm gong is also included in the ICV arrangement which is connected to the alarm valve. The alarm gong will ring in the event the alarm valve operates, notifying those in the area that the system has activated. An ICV is the main control point of a Fire Sprinkler System and is allowed to feed a maximum of 1000 fire sprinklers per ICV.

Fire Sprinklers work as a form of passive fire protection. Fire Sprinklers operate when a certain temperature of heat is exposed onto a sprinkler's glass bulb. Sprinkler's have many different activation temperatures ranging from 68 degrees to 260 degrees celsius. A sprinkler's activation temperature is indicated by the colour of the glass bulb. Once the activation temperature of the sprinkler is achieved, the sprinkler bulb with break allowing water to flow through the sprinkler and suppress the fire below it.

Most Fire Protection Installations incorporate closed bulb Fire Sprinklers. This is when only the Fire Sprinklers in the immediate vicinity of the fire will activate. A Fire Sprinkler will only operate once the activation temperature of the sprinkler's glass bulb has been achieved. Some Fire Sprinkler systems incorporate open head fire sprinklers. These systems are called Deluge systems. These are the only Fire Sprinkler systems which activate all the fire sprinklers at once.

Fire Pumps and Fire Water Storage Tanks are generally installed when the council water supply to your premises is hydraulically inadequate to meet the hydraulic requirements of your Fire Protection System. Fire Pumps and Fire Water Storage Tanks are also recommended in the event the council water supply is intermittent or not guaranteed at all times.

An Ordinary Hazard Fire Sprinkler System is designed for light non commercial, commercial and industrial occupancies. These occupancies involve the handling, processing and limited storage of materials unlikely to develop intensely burning fires in the initial stages.

A High Hazard Fire Sprinkler System involves mainly commercial and industrial occupancies. These occupancies involve the handling, processing and storage of materials of a combustible nature likely to develop rapid and intensely burning fires.

An ICV should be checked on a weekly basis with an Overhaul being completed every three years. An alarm valve overhaul includes servicing the valve as well as replacing the alarm valve rubber gaskets together with an approved ASIB tag.

A Fire Pump should be checked and run on a weekly basis as well as an overhaul service being completed on a yearly basis together with an ASIB approved tag.
