1. INTRODUCTION
The Syrex IS-XN is an ATEX certified intrinsically safe
beacon which will produce a visual warning in a hazardous
area. Red, Amber, Green and Blue output models are
available.
2. DESCRIPTION
The device will start to flash when power is applied to
terminals + and -. The beacon has two flash rates one double
flash per second and two double flashes per second. The
flash rate is selected by setting an internal pin header. The
unit is factory set to produce two double flashes per second.
3. SUPPLY VOLTAGE
The Syrex IS-XN beacon has been designed to operate in a
hazardous area via a 28V 300 ohm ATEX certified Zener
barrier or galvanic isolator. The beacon may be tested or
used in safe areas without a Zener barrier or galvanic
isolator, but at supply voltages above 16V the internal current
limit will function and the brightness may be reduced. The
beacon should not be continuously operated without a barrier
or isolator with a supply voltage greater than 16V.
4. INTRINSIC SAFETY CERTIFICATION

temperatures in the range -40
o
C to +60
o
C and
should not be used outside this range.
4) The certificate number has an ‘X’ suffix, which
indicates that the certificate contains one of more
special conditions for safe use. Those installing or

If the equipment is likely to come into contact with
aggressive substances, then it is the responsibility of
the user to take suitable precautions that prevent it
from being adversely affected, thus ensuring that the
type of protection is not compromised.
“Aggressive substances” - e.g. acidic liquids or
gases that may attack metals, or solvents that may
affect polymeric materials.
“Suitable precautions” - e.g. regular checks as part
of routine inspections or establishing from the
material’s data sheet that it is resistant to specific
chemicals.
