Smoke reaches sleeping people long before they see flames. Read on: it takes a few minutes and could save you a lot more than that. **In this guide you will see:** - Inputs: smoke/heat detectors and manual call points. - The panel decides and shows where the alarm came from. - Outputs: sounders, beacons and links (e.g. door releases). Quick answer A fire alarm system has inputs (automatic detectors and manual call points), a control panel that decides what to do, and outputs (sounders, beacons and links to other systems). The panel runs on mains power with standby batteries, and shows which zone or device triggered the alarm.

'Cause and effect' is the programming that says what happens next: which sounders operate, which doors release, whether a notification is sent. Compare panel types in [conventional vs addressable](https://qyvea.co.ke/conventional-vs-addressable-fire-alarm-kenya), and plan with the [fire alarm planning guide](https://qyvea.co.ke/fire-alarm-planning-guide-kenya). **Important**: Fire alarm design should follow a recognised standard (British Standard BS 5839-1 is widely used) and any requirements from the local authority or insurer. ## Frequently asked questions How does a fire alarm know where the fire is? Devices are grouped into zones or given individual addresses, and the panel shows which one triggered. Does a fire alarm work in a power cut? Yes. The panel has standby batteries sized to keep the system running and then sound the alarm. How often should a fire alarm be tested? BS 5839-1 recommends a weekly user test of a call point and servicing by a competent person at least every six months. ## Why customers choose Qyvea **Genuine brands**: Manufacturer warranty on what we sell, so you are not gambling on the box. **One team, start to finish**: The people who advise you also install and support it. **Fast answers**: WhatsApp replies usually within 30 minutes, and delivery within 24 hours in Nairobi. **Easy to buy**: Pay by M-Pesa, bank transfer or card.
