Burglar alarms in Sunningdale

Many of Sunningdale's freestanding properties have been renovated, making their original alarms unreliable or incomplete. Our service for burglar alarms in Sunningdale is to assess these inherited systems, adapting them to secure the home's current layout and replacing any ageing, unreliable components.

Sunningdale alarms: upgrading systems in established and renovated homes

Sunningdale is about 6 km south-east of Sandton City. Many Sunningdale homes are established, freestanding properties with boundary walls that have been standing for decades. An alarm system installed years ago may not account for renovations that have changed window layouts or added a patio. Older wiring can become unreliable, and components might fail without warning, creating unseen gaps in protection along perimeters on roads like Avon Road or Swemmer Road.

Our approach in Sunningdale is to first assess the entire existing system. We test the control panel, wiring, and every detector to find what can be kept and what needs replacing. We then design a layout that covers the property as it stands today, adding outdoor beams to detect intruders in the garden and updating indoor protection to match any new extensions or altered floor plans.

With frequent power outages, the backup battery is a important point of failure in older Sunningdale alarm systems. A small, ageing battery might not last through a long outage, leaving the property vulnerable. On every visit, we test the battery's health and can install larger-capacity units that are better suited to keeping the alarm fully active through extended periods without mains power.

Everything we install and repair, and how a job runs from first call to handover, is on our alarm systems page.

Questions from Sunningdale

My alarm panel is very old. Does the whole system need to be replaced?

Not always. If the panel is still functional and compatible, we can often add new detectors, beams, and a modern communicator to it. Tyson will assess the panel on-site and explain what can be re-used and what needs to be upgraded.

My alarm started having problems after we renovated. Can you fix it?

Yes. Renovations often disturb wiring or create new areas that need protection. We can trace the faults in the existing system and add new detectors or beams to make sure your home's new layout is properly secured.

Every Sunningdale property is different, so we look before we quote. Send us a photo or call, and we will arrange a visit and a written quote for your burglar alarm work.

What our alarm customers say

  • Our alarm siren suddenly stopped sounding even though the system was still arming. Tyson found the fault quickly, replaced the damaged component and tested the complete system before he left.

  • We asked One Point to install panic buttons in a few key areas of our home for an elderly family member. Tyson explained the best positions and made sure everyone understood how to use them.

  • We asked One Point to check our alarm before going away for a few weeks. Tyson tested every detector, replaced the backup battery and fixed a door contact that we didn't realise was faulty.
