The IS-mC1 combined unit is CE
marked for compliance with the
European Explosive Atmospheres
2014/34/EU and the European EMC
Directive 2014/30/EU
1)
Introduction
The IS-mC1 minialert is an ATEX, IECEx and UKEX certified
intrinsically safe combined sounder/beacon unit which
produces both a loud audio warning and a visual warning and
can be installed in a hazardous area. The sounder section
has forty-nine first stage alarm sounds that can be selected
by internal switches and each one can be externally changed
to a second or third stage alarm sound. The beacon section
can be set internally for a flash rate of either 1Hz or 2Hz. The
combined unit sounder and beacon can be operated
simultaneously from one barrier or from separate barriers if
independent operation is required. The IS-mC1 Combined
Unit can be used in all gas groups IIA IIB and IIC.

Description
Fig 1 shows a simplified block diagram of an IS-mC1
minialert sounder section. The device operates immediately
power is applied to the sounder + and – terminals which are
duplicated to allow a second sounder to be connected in
parallel, or for an end of line monitoring resistor to be
installed. The output tone is defined by the positions of the
six internal switches and this tone can be changed to a
second or third stage alarm tone by connecting terminals S2
or S3 to 0V. The tone generator is crystal controlled to ensure
that when two sounders connected to the same power supply
are started at the same time the output tones remain
synchronised.
3)
Supply Voltage
The IS-mC1 minialert unit has been designed to operate in a
hazardous area from a 24V dc supply via 28V 93mA resistive
ATEX and IECEx certified Zener Barriers or Galvanic
Isolators. The unit 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
therefore it is recommended that they are not operated
continuously with a direct supply greater than 16V.

EN60079-11:2012
IEC60079-26:2014
II 1G
Ex ia IIC T4 Ga (-40ºC <= Ta <= +60ºC)
The EC-Type Examination Certificate SIRA 05ATEX2084X
has been issued by the Notified Body Sira. This confirms
compliance with the European ATEX Directive 2014/34/EU
for Group II, Category 1G equipment. The sounder carries
the Community Mark and subject to local codes of practice,
may be installed in any of the EEA member countries. This
instruction sheet describes installations which conform to
EN60079:Part14:2008 Electrical Installation in Hazardous
Areas. When designing systems for installation outside the
UK, the local Code of Practice should be consulted.
