3.2.3 Environment points to be considered when use
ㆍ Installation places and availability of fuels (Family of Hydrocarbon and related
flame detection)
ㆍ install product according to its Installation space and it areas of dangerous
(internal/external etc)
ㆍ Select place of installation according to detection range and field of view
ㆍ Temperature range [Min/Max] of operation/installation
ㆍ Select the place to avoid the area with obstructed object for the appropriate installation
ㆍ Select the place to avoid the area with false alarm statuses affect to the fire detection
※ The above points of considerations are based on the basic environmental standard and
they are vary different between countries in terms of environment, usage, users etc.

ㆍ Loop connection with several detectors
This is Loop type connection method which can generate alarm and fault signal. But
with this connection, detection performance is blocked when one flame detector is in fault
condition. So this method is only avaliable with specific receiver which can check fault
signal frequently and automatically.
