Risco Battery Fault — Backup Battery Failure

What Does This Error Mean?

A Battery Fault on your Risco panel means the backup battery is either failing, not charging, or has been disconnected. Your alarm works normally on mains power, but will not function reliably during a power cut.

Affected Models

Risco LightSYS
Risco LightSYS Plus
Risco ProSYS Plus
Risco WisDom
Risco Agility

Common Causes

Backup battery has aged beyond usable life (typical lifespan 3–5 years)
Battery was deeply discharged during a long power cut and will not recover
Battery connector inside the panel is loose
Panel charging circuit has failed

How to Fix It

Check the age of the battery

If the system has not had a battery replacement in the last 3–5 years, the battery has almost certainly aged beyond useful life.
Acknowledge the fault on the keypad

Enter your code and press Off/Disarm to silence any beeping. This does not fix the battery — it just silences the alert.
Contact your alarm installer

Risco panels are typically installed by certified security companies. Ask your installer to replace the battery on their next visit, or schedule a dedicated call-out.
Do not delay

A dead backup battery is a meaningful security risk. Power outages — including those caused deliberately — leave your alarm unprotected if the battery is flat.

When to Call a Professional

Yes — battery access inside a Risco panel requires removing the cover, which may trigger tamper conditions and may require installer-level reset.

Risco Battery Fault Explained

Your Risco alarm panel contains a 12V sealed rechargeable battery that sits inside the main control box. This battery is the system’s lifeline during a power cut.

A Battery Fault means this lifeline is no longer reliable.

Signs Your Battery Is Ageing

Battery fault appears shortly after a power cut (battery drained quickly)
Battery fault appears even while mains power is present (battery not charging)
Battery fault after a period of cold weather (cold reduces battery capacity)

What Happens If You Ignore It?

Your alarm continues to work normally on mains power. But in any power cut — including one caused deliberately by an intruder — the system will fail within minutes rather than hours. Replace the battery promptly.

Frequently Asked Questions

What battery does a Risco LightSYS use?

The Risco LightSYS typically uses a 12V 7Ah sealed lead-acid (SLA) battery. Your installer can confirm the correct type and source the replacement.

Can I replace the battery myself without an installer?

Physically, the battery swap is simple. However, opening the panel may trigger tamper conditions that require an installer code to reset. Most homeowners find it easier to ask their installer.
