Water extinguishers Servicing London & Home Counties

Used exclusively for Class A fires, water fire extinguishers operate by cooling burning materials by absorbing heat. Signified by a red stripe, water extinguishers are not suitable in certain environments, especially those that are at risk from electrical fires.

AAI Security Systems supply, install and maintain a range of water fire extinguishers throughout London and the Home Counties, providing high quality units that are fully approved by both NSI and BAFE.

Fire extinguishers Is your business protected? Over 80% of businesses never recover from the effects of a fire. We can give you a full audit to ensure you are fully protected and covered for all your premises.

Having fire fighting equipment installed at your premises is useless if it is not properly maintained. AAI offer regularly scheduled and one-off servicing, repairs and replacements for all water fire extinguishers at properties across the region.

Our ongoing aftercare service ensures that your units are thoroughly inspected for damage and usage, and AAI's experienced team of experts are on hand to provide advice and assistance regarding your fire safety practices, helping you to stay compliant with industry regulations.
