Limitation of Smoke Detectors
The smoke detector is designed for triggering and initiating emergency fire equipment, however it
only functions when matching with other equipment’s. Installation of this smoke detector must
conform to electrical codes and country standards.
All kinds of smoke 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 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 detector used in high velocity environment will be
delayed due to dilution of smoke by frequent and fast airflow. What’s more, the smoke detector has
to be frequently maintained for it is exposed to more dust contamination.
The smoke 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 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 detectors, fire alarm devices or any other
components of the system must be repaired and/or replaced immediately as they fail.
