The JA-151ST consists of two independent detectors – an optical smoke detector and a heat detector. The optical smoke detector works on the principle of scattered light. It is very sensitive to large dust particles which are present in dense smoke. It is less sensitive to smaller particles generated by the combustion of liquids such as alcohol. That is why the fire detector also contains a built-in heat detector which has a slower reaction but is much better at detecting fire which generates only a small amount of smoke.

Fire in the hole!

Important is that the design is attractive, because you should not hide fire sensors in any corner etc. This one with its own siren will replace your ordinary smoke detectors - a very good thing.

Product Questions
After how many years do I have to replace an old fire detector with a new one?
Question by: Wolfgang on Jun 7, 2025, 1:22 PM
A fire detector (smoke / heat detector) should generally be replaced every 10 years. This is the standard service life of most smoke detectors, including those from Jablotron, Notifier and DSC.
Why replace after 10 years?
> Sensor ageing: The smoke detector loses its sensitivity over time.
> Battery wear: Even models with long-life batteries can run out after 10 years.
> Reliability: After 10 years, the risk of faults increases and security systems must always be reliable.
