Sona Studio Islington Fire Alarm Commissioning
We commissioned the new fire alarm at Sona Studio, 173 Upper Street in Islington, a new movement and wellbeing studio getting ready to open its doors. Cannonbury Electrical from Amersham installed the system, and we tested it, set it up and certified it. The system runs on a C-TEC CFP AlarmSense panel covering five fire zones, with Apollo AlarmSense detectors, call points and sounders throughout.
Why a Two Wire System Works Here
AlarmSense puts detectors, call points and sounders on the same pair of wires. That means less cabling to run through a finished shop unit on Upper Street and a faster, tidier install for the electrician. You still get a conventional system that is simple to use, with the panel showing staff which zone has gone into alarm. For a studio opening to the public, the alarm has to work properly from day one, so every visitor and member of staff hears the warning and gets out quickly.
What We Did
• Inspected the installation against the design and BS 5839-1:2025
• Tested every detector and call point and checked each one reports to the right zone
• Checked the panel zone labels match the zone plan on the wall
• Measured alarm sound levels across the studio
• Tested the fire and fault outputs and the panel controls
• Checked the standby batteries and handed over the certificate, zone plan and logbook
Working With Electrical Contractors
Cannonbury Electrical installed the cabling and devices, and we brought the system to life and certified it. It is a partnership that lets electrical contractors take on fire alarm projects with confidence.
