A large Karen home has many doors and windows, outbuildings and a long boundary, and intruders know there is often a lot of ground between the gate and the house. By the time a dog barks, they may already be at a window.

Alarm system installation in Karen is about early warning across the whole property. Nerpax combines outdoor beams along approaches to the house, contacts on doors and windows, and interior motion detectors, so an intruder is detected on the way in, not only once inside. Outbuildings such as stores and garages can be added as separate zones.

Alerts go to your phone and a siren sounds at the house. Panic buttons in the bedroom and kitchen let household members call for help. We can also link the alarm to the electric fence and outdoor lighting.

We survey the property, design zones, install, test and train the household. Book a site visit.

Serving Karen

Karen is known for large leafy plots, long driveways and spacious homes, with Karen Road, Langata Road and Ngong Road framing the area. Big compounds mean long boundaries, so electric fencing, perimeter CCTV and intruder alarms with outdoor sensors are common needs. Many homes have boreholes, staff quarters and outbuildings, which makes solar pumping, solar power systems and a reliable generator changeover practical. Automated gates save trips down the driveway in the rain. Nerpax Systems serves Karen homes, schools and businesses with supply, installation and delivery.

Alarm System Installation in Karen: FAQs

Can outdoor beams work on a property with dogs?

Yes, with careful placement. Beams can be mounted higher than a dog's height, or set to need two beams broken at once, so dogs moving around do not trigger them. We discuss your pets and their usual movement during the survey before choosing detector positions.

Can the alarm be armed at night while we are at home?

Yes. A night or stay mode arms the perimeter and outdoor zones while leaving bedrooms and hallways inactive, so the household can move around freely. Anyone forcing a door or window, or crossing an outdoor beam, still triggers the alarm.
