Willow Fire & Security supplied and fitted new batteries in both of these AOV panels in East London following a 6 monthly service. We found that these were out of date following routine maintenace and replaced them following week with new batteries.
AOV panel batteries need regular testing and timely replacement to ensure the system operates reliably in the event of a fire or power failure. Here’s why:
1. Ensures Emergency Functionality
AOV panels rely on backup batteries to operate during power outages. If the mains supply fails, the batteries must have enough charge to open vents and extract smoke.
2. Prevents Battery Degradation
Over time, batteries naturally lose capacity due to chemical aging, reducing their ability to hold charge and deliver power when needed. Testing ensures they are still performing within safe operational limits.
3. Complies with Fire Safety Regulations
Fire safety regulations, such as the BS EN 12101-10 standard for smoke control systems, require AOV panels and their backup power supplies to be regularly tested and maintained.
4. Identifies Early Signs of Failure
Regular testing detects issues such as low voltage, poor charging, or internal resistance, preventing unexpected failures in an emergency.
5. Avoids Costly Repairs & System Downtime
Failing batteries can cause panel faults, alarms, or system failures, leading to expensive emergency repairs and potential legal risks for non-compliance.
6. Ensures Compliance with Manufacturer Recommendations
Most AOV panel manufacturers recommend battery replacement every 4-5 years, depending on the type and usage, to ensure reliability.
