Sprinklers should be fitted in all new residential properties, according to East Sussex Fire and Rescue Service.
Des Prichard, chief executive and chief fire officer of the fire service, has backed the National Fire Sprinkler Network's campaign to install sprinkler systems in new homes in England, Scotland and Northern Ireland.
In April, legislation requiring the inclusion of domestic sprinkler systems in all new-build new homes in Wales was passed unanimously and received Royal Assent.
Now, the National Fire Sprinkler Network wants this extended to the rest of the UK and Mr Prichard is supporting the non-profit organisation's work.
"As well as fitting smoke alarms, installing sprinklers will ensure early intervention to control a fire until the fire service arrives," he said.
"Automatic sprinkler systems are exceptionally effective through their ability to control a fire in its early stages, minimising the risk and damage from fire."
An online petition has been launched for members of the public to pledge their support for the National Fire Sprinkler Network's campaign.
