Addressable · conventional · detectors · commissioning
GS TechGuard carries out fire alarm installation in Nairobi and across Kenya for offices, apartments, warehouses, schools, hospitals and hotels. We design the layout from your floor plans, install the panel, detectors, call points and sounders with fire-rated cable, test every device and hand over records you can keep in the building file.
Most commercial buildings in Nairobi need an addressable system, because the panel shows exactly which detector tripped and on which floor. Smaller premises can work well with a simpler conventional system. Either way, a reliable fire alarm installation depends on three things: the right devices in the right places, cabling that survives a fire long enough to do its job, and proper testing before anyone relies on it.
So this page explains how to choose a system, what installation includes, how layouts differ by building type, and what testing and records you should expect.
Options compared
| Feature | Conventional system | Addressable system |
|---|---|---|
| How it reports | By zone, such as "Ground floor east" | By device, such as "Room 204 smoke detector" |
| Wiring | One circuit per zone | Loops that carry many devices each |
| Size suited | Small buildings, up to a few zones | Medium to large buildings, multi-storey |
| Fault finding | Search the whole zone | Panel shows the exact device |
| False alarm control | Basic | Better, with sensitivity and verification settings |
| Upfront cost | Lower | Higher, but often lower per device on large sites |
As a rule of thumb, a single-storey shop or small office can use conventional. However, apartments, offices of several floors, schools, hospitals and hotels benefit from addressable systems. When an alarm sounds at 2 a.m. in a twelve-storey block, knowing the exact room saves precious time.
How it works
The aim is a system that works first time and keeps working for years with routine care. Because every step is recorded, any competent engineer can later check what was done.
Fire Alarm Installation
Different rooms need different detectors. Putting a smoke detector in a kitchen, for instance, leads straight to false alarms.
During every fire alarm installation, we check ceiling height, airflow and room use before choosing.
Fire safety
| Building | Key design points |
|---|---|
| Apartments | Detection in common areas and escape routes; heat detectors near flat entrances; clear sounder coverage on every landing |
| Offices | Addressable loops per floor; links to access control doors and lifts |
| Warehouses | Beam or aspirating detection under high roofs; loud sounders and beacons over machinery noise |
| Schools | Simple zoning, loud sounders in classrooms and dormitories, call points at every exit |
| Hotels | Detection in every room, voice evacuation in public areas, links to the PA system |
| Hospitals | Careful zoning for phased evacuation and quiet alerts in clinical areas |
For apartments and estates in particular, the apartments and estates page shows how fire alarms combine with cameras and intercoms.
Support and maintenance
Commissioning then proves the system works. We test every detector with the correct test equipment, operate every call point, measure sound levels in each area and test every interface. In addition, we run the system on batteries to confirm standby time.
Keep these records in the building file. Auditors, insurers and the fire department may ask for them.
Fire safety
A fire alarm installation should never stand alone. When the alarm sounds, escape doors fitted with electronic locks must open. We wire the panel to access control door controllers so this happens automatically. In larger buildings, the panel also switches the PA to evacuation messages through a voice evacuation system.
Emergency lighting works alongside the alarm to light escape routes during power failures. See our emergency lighting page. Panels carry standby batteries, and we check that related systems such as door locks have their own UPS backup.
Costs and pricing
As a rough guide, a small conventional system for a shop or small office may start from around KSh 80,000 installed. Addressable systems for multi-storey buildings are quoted after a survey. Our guide to fire alarm costs in Kenya explains typical ranges, and the fire safety and life safety systems page shows how the whole picture fits together.
Workplaces in Kenya fall under the Occupational Safety and Health Act, 2007, and the Fire Risk Reduction Rules, 2007, which require fire risk management, warning systems and regular drills. Local authorities and insurers may add their own requirements. We design to a recognised standard agreed with you and can provide documents for your fire safety audit. The Directorate of Occupational Safety and Health Services publishes guidance for employers.
Frequent false alarms are dangerous, because people stop reacting. So we design each fire alarm installation to keep them rare. For example, we use heat detectors in kitchens, keep smoke detectors away from bathroom steam and air conditioning outlets, and choose multi-sensor detectors in tricky areas. On addressable panels, we can also set a short check before a single detector raises a full alarm in certain zones, where the standard allows it.
After handover, we review any false alarms with you during service visits. In most cases, a small change to a device type or position solves the problem for good.
How it works
Every fire alarm installation needs regular care. Detectors collect dust, batteries age and buildings change. Our fire alarm maintenance plans include service visits every six months, fault repairs and record keeping.
Why choose us
We work across Nairobi, including Westlands, Upper Hill, Kilimani, Industrial Area and Embakasi, and throughout Kenya. To plan a fire alarm installation for your building, request a site survey.

A small conventional system for a shop or small office may start from around KSh 80,000 installed. Addressable systems for multi-storey offices, apartments and hotels cost more and are quoted after a survey. The main drivers are building size, detector types, cabling routes and interfaces with doors, lifts and PA.
Conventional systems suit small, single-storey premises with a few zones. Addressable systems suit larger and multi-storey buildings because the panel shows the exact device that triggered. They also help reduce false alarms and speed up fault finding. We recommend the right type after looking at your floor plans.
Good practice is a professional service every six months, with a weekly call point test by your own staff recorded in the logbook. Busy, dusty or high-risk buildings may need more frequent visits. Your insurer or fire safety auditor may also set their own requirements.
It should, on escape routes. We connect the fire panel to the access control system so electronically locked escape doors release automatically when the alarm sounds. Each door also has a green break-glass unit for manual release. We test this link during commissioning.
