10. Appendix 1
10.1. Limitation of Beam Detectors
The beam detector is designed for triggering and initiating emergency fire
equipment’s; however, it only functions when configured correctly with other
equipment. Installation of this beam detector must conform to electrical codes and
country standards.
All kinds of smoke detectors have restrictions, since fire develops in various ways
and can often be unpredictable in their progression, it is unforeseeable which type
of detector will provide the earliest warning. No types of beam 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 beam detector has to be frequently maintained for it is exposed to
more dust contamination.
The beam 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 national codes and laws. Take
specific maintenance measures on the basis of different environments.
The beam detector contains electronic parts. Even though it is designed
manufactured to last for a long time, any of these parts could fail at any time.
Therefore, test your beam detector at least every 6 months 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.
