Solo A5 is the new smoke aerosol designed to enable functional testing of smoke detectors. Like all Solo products, Solo A5 is approved by leading detector manufacturers and offers the reliability and quality expected by the industry. Chemicals used in detector test equipment need to be compatible with the plastics from which the detectors are manufactured. Not all test aerosols offer this compatibility which can lead to problems such as stress cracking in detectors, residue build-up and damage to the detector and components. Solo aerosols are the most thoroughly researched solutions – approved by leading detector manufacturers, third parties and fire engineers.
