OGS HomeSafe - Fire Emergency Isolation System
The OGS Homesafe is an automated safety solution specifically engineered for residential and commercial buildings employing Multilayer Pipe systems in Australia and New Zealand. It addresses the regulations outlined in AS/NZS 5601.1:2022 by ensuring the installation is equipped with a Class 1 automatic shut-off valve integrated with the building's fire safety system. Upon fire alarm activation, OGS Homesafe cuts off the gas supply, prioritizing occupant safety and preventing potential hazards. Its innovative design also incorporates a downstream gas pressure proving mechanism, which rigorously tests the system for leaks before gas supply restoration. This ensures reliability and safety compliance, making OGS Homesafe indispensable for modern infrastructures implementing Multilayer Pipe technology.
The OGS Homesafe is designed for buildings and dwellings in Australia and New Zealand where Multilayer Pipe is used as part of the consumer piping. New buildings with multilayer pipe and modification of consumer piping in existing buildings with multilayer pipe will now require automatic isolation in the event of a fire. In the form of an class 1 automatic shut-off valve interlocked to a fire safety system
AS/NZS 5601.1.2022 States the following;
5.2.11 Provision of Fire Emergency Isolation for Multilayer Pipe
Where Multilayer pipe is used as a part of consumer piping, the following requirements for fire emergency isolation shall apply.
- (a) The installation shall be fitted with a system that will shut off the gas supply when the fire safety system operates.
- (b) The method of isolation shall be a single class 1 safety shut off valve that meets AS4629 and automatically isolates the gas supply.
- (c)The system shall provide pressure proving of the down steam installation prior to restoration.
The OGS Homesafe will isolate the gas supply in the event of a fire alarm activation. When the system is reset it will perform a downstream gas pressure proving test on the pipework to check for any leaks before the gas is restored.
