Not every part of a building needs the same type of fire detector. Using the wrong type can mean late warnings or constant false alarms.
The common types
- Smoke detectors: typically used in offices, bedrooms, corridors and escape routes where early warning matters.
- Heat detectors: often used where smoke or steam would cause false alarms, such as kitchens, boiler rooms and some plant areas.
- Multi-sensor detectors: combine more than one method.
- Manual call points: let people raise the alarm by hand.
Why placement matters
Detectors need to be sited so smoke or heat reaches them. Partition walls, shelving and changes of layout can leave gaps in coverage. A new room, a blocked ceiling void or a change of use should always prompt a check.
False alarms
Frequent false alarms are a warning sign, not just a nuisance. They can lead people to ignore the alarm. Look for causes: steam, dust, cooking fumes or a detector in the wrong place.
Design and servicing
In Ireland, I.S. 3218 is the standard for fire detection and alarm systems, and your alarm contractor will normally work to it. Your fire risk assessment checks whether the system suits how your building is really used. See our guide to fire alarm testing and servicing.
Your duties
Under the Fire Services Acts 1981 and 2003, a person in control of premises must take reasonable measures to protect people from fire. A fire risk assessment from Safer Solutions will review detection with escape routes and the rest of your fire precautions. Call 086 275 9728 or email info@safersolutions.ie.
