INTRODUCTION TO THE INTRINSICALLY SAFE FIRE DETECTION DEVICE
This wireless heat detector has been certified by Baseefa and has been awarded the ATEX Classification
II 1 G ; Ex ia IIC T5 Ga –10˚C
≤ Ta ≤ +55˚C
making it suitable for Category 1, 2 or 3 hazardous atmospheres with a maximum ambient temperature up to 55˚C.
The product has been assessed and certified for ATEX & IECEx requirements for hazardous applications according to the following standards:
IEC 60079
-
0:2011 / EN 60079
-
0:2012+A11:2013
IEC 60079

It is recommended that installation only be carried out by qualified personnel
according to hazardous area safe working practice and in conformity to the terms
of the product certification. Note that the Translator Interface to which this device
will be linked does not form part of the ATEX/IECEx certified system and must be
sited in the safe area which is not subject to hazardous conditions.
GENERAL DESCRIPTION
The intrinsically safe wireless heat detector samples the air to determine an alarm
condition in the protected environment. Its design and construction makes it
suitable for installation in hazardous environment according to ATEX DIRECTIVE
2014/34/EU. System design should follow National Regulations or Codes of
Practice including reference to standards related to hazardous areas (e.g. EN
60079
-
14:2014) as appropriate.
These detection devices are designed for indoor applications and care should be
taken to ensure the environmental conditions are suited to the device type so that
unwanted alarm conditions are prevented.
DETECTOR VISUAL LED INDICATOR
The wireless heat detector is equipped with a LED that provides visual indication
for functional modes, battery faults and other fault types (see table 1).
LINKING THE DEVICE TO THE SYSTEM
This detector must be
linked to the fire detec-
tion
system
before
installation; specifically it
must be linked to its
translator or expander
interface following the system design plan.
NOTE: As a safety precaution linking and power up of devices should
be carried out adjacent to the translator/expander interface in the safe
area.
For more detailed information about wireless linking refer to “Guide to
wireless system installation” document (APN
-
W0001) or refer to your system
supplier.
This manual gives the specific linking procedure applicable only to this detector.
