Limitation of Smoke & Heat Detectors
The Smoke & Heat detector is designed for triggering and initiating emergency fire equipment’s,
however it only functions when matching with other equipment’s. Installation of this Smoke & Heat
detector must conform to electrical codes and standards in your country.
All kinds of Smoke & Heat detector have restrictions, since fire develops in varies ways and are often
unpredictable in their progression, it is unforeseeable which type of detector will provide the earliest
warning. No types of Smoke & Heat detector can sense every form of fire all the time. Generally
speaking, detectors may not warn you about fire caused by insufficient safety measures, violent
explosions, leaking gas, improper storage of flammable materials like diluents and other safety
hazards, arson or children playing with fire. The alarm of a Smoke & Heat detector used in high
velocity environment will be delayed due to dilution of smoke by frequent and fast airflow. What’s
more, the Smoke & Heat detector has to be frequently maintained for it is exposed to more dust
contamination.
The Smoke & Heat detector cannot last forever. In order to keep the detector working in good
condition, please maintain the equipment continuously according to recommendations from
manufacturers and relative nation codes and laws. Take specific maintenance measures on the
basis of different environments.
The Smoke & Heat detector contains electronic parts. Even though it is made to last for a long
period of time, any of these parts could fail at any time. Therefore, test your smoke detector at least
every half-year according to national codes or laws. Any Smoke & Heat detectors, fire alarm
devices or any other components of the system must be repaired and/or replaced immediately as
they fail.
