Alarm Systems

Types of alarm systems we install

An alarm system is a set of detectors connected to a control panel. When a detector is triggered, the panel sounds the siren and sends alerts. Choosing the right type depends on your property and what you are protecting against.

Intruder alarm systems

These protect against break-ins. Door and window contacts trigger when an opening is forced. PIR motion sensors detect movement inside rooms and corridors, and pet-tolerant models help homes with dogs or cats. Outdoor beams and sensors can cover verandas, parking areas and perimeter walls. Most homes use a mix, with a part-arm setting so you can protect the ground floor at night while you sleep upstairs.

Panic buttons

A panic button lets you raise the alarm silently or loudly during an emergency. They are common in bedrooms, reception desks, banking halls, pharmacies and petrol stations. Wireless panic buttons can be carried around the compound.

GSM and app-connected alarms

A GSM module or app link sends SMS, calls or push notifications when the alarm triggers, when power fails or when someone arms or disarms the system. This is what turns a siren into a real response, especially if you live alone, travel or own a business that is empty at night. Alerts can also go to your security company if you have one.

Fire alarm systems

Fire alarms use smoke and heat detectors, manual call points and sounders to warn everyone to get out early. Conventional systems divide a building into zones and suit small offices, shops and homes. Addressable systems pinpoint the exact device that triggered and suit schools, hospitals, hotels and larger commercial buildings. Many workplaces and institutions need a working fire alarm to meet county fire safety inspections.

Wired or wireless

Wired systems are very reliable and best fitted during construction or renovation. Wireless systems install faster with less disruption in finished homes, but their batteries need regular replacement.

What affects the cost of an alarm system

• The number of doors, windows and rooms to protect
• Wired or wireless equipment
• Whether you add GSM or app alerts
• Intruder only, fire only or both
• Building size, ceiling heights and cable routes

As an indicative 2026 guide, a basic intruder alarm for a typical home with a few sensors, a siren and GSM alerts is often in the range of KES 35,000 to 120,000. A conventional fire alarm for a small office or shop often starts from around KES 80,000, while addressable systems for larger buildings cost considerably more. Every price depends on site; confirm with a free site survey.

Who needs an alarm system

• Homes: bungalows, maisonettes and townhouses, especially when the house is often empty.
• Landlords and apartments: fire alarms for common areas and stairwells, and intruder alarms for stores and offices.
• Businesses: shops, offices, warehouses, pharmacies and agrovets with stock and cash on site.
• Institutions: schools, churches and clinics that need fire detection and protection for equipment.

An alarm works best as part of layered security. Pair it with CCTV systems to see what triggered the alarm, and with an electric fence to stop intruders at the wall.

Maintenance and aftercare

Alarms fail quietly. Backup batteries wear out, sensors get blocked by furniture and smoke detectors collect dust. We recommend testing your system regularly and having it serviced at least once a year, with battery replacement as needed. We can service systems we installed and check existing alarms installed by others. Spare sensors, sirens and batteries are available through our online shop.
