Fire alarm installation Servicing London & Home Counties

A fire alarm can be rendered wholly ineffective if it is not properly installed. Luckily, the experts at AAI Security Systems are on hand to carry out full and thorough fire alarm fitting across London and the wider Home Counties area.

With recent legislation stating that all fire and smoke alarms must be tested and certified by the NSI, and AAI were among the first companies to be accredited by this scheme. This not only means you receive an exceptional standard of installation, but that you can also rest assured that your alarm system is fully compliant with the relevant regulations.

We work to install fire alarms across all domestic and commercial premises, whether rented accommodation, office buildings, retail units, warehouses or leisure and hospitality environments.
