SLAT designs and manufactures alimentations électriques de sécurité and backup power for critical building systems, with fire safety as its first market alongside access control and video protection. Its fire-safety range is certified NF and VdS, the NF certification obtained under the APSAD rules through partner laboratories — the route that AES equipment serving an SSI must follow under EN 54-4. The company works from the Lyon area and has been trading for close to seventy years.
