Heat detectors are chosen where smoke detection would cry wolf — kitchens, boiler rooms, workshops, car parks — and the trade is explicit: they respond later, because a fire has to raise the air temperature before anything happens. EN 54-5 covers point heat detectors and classifies them by the temperature at which they operate and by whether they respond to a rate of rise as well as a fixed threshold. The specification error is choosing a class whose static response temperature sits below the normal peak of the room, which produces exactly the nuisance alarms it was meant to avoid.
The more of this you send, the closer the first quotation lands.
| Standard required | EN 54-5, or NFPA 72 for a US-specified system |
|---|---|
| Detector class | The EN 54-5 class matching the room's normal temperature range |
| Normal peak temperature | The highest temperature the space reaches in ordinary use |
| Response type | Fixed temperature, rate of rise, or combined |
| Panel compatibility | Conventional, or the addressable protocol in use |
| Mounting height | Affects spacing and response time |
| Environment | Kitchen, plant room, car park, workshop, loading bay |
| IP rating | Where washdown, dust or moisture is present |
| Base type | Standard, relay, sounder or isolator base |
| Linear heat detection | State if cable-type detection suits the risk better |
| Local approval | State if Saudi Civil Defence approval is required |
| Quantity | Units per class, plus bases and spares |
