ALF300 Fire Extinguisher (for use with anti arson letterbox)

The ALF 300 Fire Detector & Extinguisher is a sealed for life unit which comes with a 5 year manufacturers guarantee.

(Tests have shown however that ALF extinguishers over 10 years old have still proven fully effective).

The ALF extinguisher (Automatic Linear Fire Detector/Extinguisher) consists of a sealed plastic tube filled with a special extinguishant gas stored under pressure.

Unlike conventional fire extinguishers, ALF Fire Extinguishers do not require an annual pressure test to check their performance capability, but it is recommended that they be replaced at the end of each 5 year period (or immediately after any activation).
