Powering Protection: The Critical Role of SLA Batteries in Emergency Systems

In today’s world, dependable backup power is more than a convenience, it’s a necessity. Life safety and security systems, from fire alarms to emergency lighting and surveillance, rely on batteries to keep working when the unexpected happens.

At Power-Sonic, we’ve been supporting that critical need for over 55 years. Our Sealed Lead Acid (SLA) batteries are a trusted choice across the industry—because when the power goes out, they keep essential systems running.

Why Backup Batteries Matter

Power failures can happen anytime, with storms, outages, or emergencies. When they do, critical systems like alarms, access control, and emergency lighting need to keep running. Backup batteries bridge the gap, helping keep people safe and secure until normal power returns.

But reliability matters. In life safety systems, not all batteries are up to the job. Performance, durability, and compliance with safety standards are essential when lives and property are on the line.

• Fire Alarm Control Panels:
Keep detection, notification, and control circuits running during outages. Code-compliant backup power is a requirement in most jurisdictions.

• Security Access Panels & Intrusion Systems:
Ensure doors function properly, alarms stay active, and perimeters remain secure even if power is lost.

• Emergency Lighting and Exit Signs:
Provide light in hallways, stairwells, and exits during blackouts—critical for safe evacuation.

• CCTV & Surveillance Equipment:
Maintain video recording and monitoring capabilities, especially in areas without immediate generator support.
