INSTRUCTION MANUAL
IS-mA1 Minialarm
Intrinsically Safe Round Sounder
1) Introduction
The IS-mA1 minialarm is an ATEX and IECEx certified
intrinsically safe sounder which produces a loud warning
signal in a hazardous area. Forty-nine first stage alarm
sounds can be selected by internal switches and each one
can be externally changed to a second or third stage alarm
sound. The sounder may be used in all gas groups IIA IIB
and IIC.
2) Description
Fig 1 shows a simplified block diagram of an IS-mA1
minialarm sounder. The device operates immediately power
is applied to the + 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-mA1 minialarm sounder 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 sounders 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.

3) The equipment is only certified for use in ambient
temperatures in the range -40oC to +60oC 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
inspecting the equipment should refer to this section
of the certificate.
5) The equipment has not been assessed as a safety-
related device (as referred to by Directive 94/9/EC
Annex II, clause 1.5).
6) Installation of this equipment shall be carried out by
suitably-trained personnel in accordance with the
applicable code of practice.
7) Repair of this equipment shall only be carried out by
the manufacturer or in accordance with the
applicable code of practice.
8) The certification of this equipment relies on the
following materials used in its construction:
Enclosure: ABS Plastic
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.
SPECIAL CONDITIONS FOR SAFE USE (as stated in the
EC Type Examination Certificate SIRA 05ATEX2084X)
Conditions for IS-mAl Sounder
The equipment has an ingress protection rating of IP65.
However, if it has been supplied without cable entry devices,
then the user shall ensure that the devices that are fitted will
provide an ingress protection that is appropriate to the
environment in which it is installed i.e. IP20 or better. If only
one of the two cable entries are used, then the unused entry
'knockout' shall be left intact or fitted with a blanking device
that ensures ingress protection appropriate to the
environment in which it is installed i.e. IP20 or better.
The total capacitance connected to terminals + wrt - (i.e. the
capacitance of the cable plus any other capacitance) shall
not exceed 83nF.
The enclosure is non-conducting and may generate an
ignition-capable level of electrostatic charges under certain
extreme conditions. The user should ensure that the
equipment is not installed in a location where it may be
subjected to external conditions that might cause a build-up
of electrostatic charges on non-conducting surfaces,
additionally, cleaning of the equipment should be done only
with a damp cloth.
The equipment shall only be supplied via Terminals + w.r.t.
Terminals - from a barrier having a maximum open circuit
voltage Uo that is < 28V and a maximum short circuit current
Io that is < 93mA, where Io is resistively limited. The barrier
shall be ATEX certified by a notified body.
4.2 Zones, Gas Groups and Temperature Classification
The IS-mA1 minialarm sounder has been certified Ex ia IIC
T4. When connected to an approved system it may be
installed in:
Zone 0 explosive gas air mixture
continuously present.
Zone 1 explosive gas air mixture likely to occur in
normal operation.
Zone 2 explosive gas air mixture not likely to occur,
and if it does, it will only exist for a short time.
Be used with gases in groups:
Group A propane
Group B ethylene
Group C hydrogen
Having a temperature classification of:
T1 450ºC
T2 300ºC
T3 200ºC
T4 135ºC
4.3 Terminals + and -
Power is supplied to the sounder via the + and – terminals
which have the following input safety parameters:
Ui = 28V
Ii = 93mA
Pi = 660mW
Ci = 0 Li = 0
The IS-mA1 sounder may be powered from an ATEX certified
Zener barrier or galvanic isolator which have output
parameters equal to or less than 28V, 93mA and 660mW,
where Io is resistively limited. The cable parameters stated
on the selected Zener barrier or galvanic isolator certificate
must be observed.
Up to three IS-mA1 sounders can be connected in parallel
and powered from a common barrier or isolator. Connecting
two sounders in parallel will reduce the output from each by
about 3dB. Three sounders should only be powered from a
common supply when the maximum supply voltage is
available.
4.4 Terminals S2 and S3
When terminals S2 or S3 are connected to 0V (- terminal) the
sounder output tone changes to the second or third stage
alarm respectively. The input safety parameters for these
terminals are:
Ui = 28V
Ii = 0mA
Because the permitted input current is zero, these terminals
may only be connected to a diode return barrier, an
intrinsically safe relay or a galvanic isolator, all of which must
have been certified by an EC Notified Body. Only diode return
barriers with a voltage drop of less than 0.9V may be used.
Alternatively, these terminals may be connected directly to a
mechanically activated switch within the hazardous area.

4.5 Other intrinsic safety certifications
Please contact European Safety Systems Ltd. for details of
non-European intrinsic safety approvals.
5) Installation
IS-mA1 minialarm sounders should only be installed by
trained competent personnel.
5.1 Mounting
The IS-mA1 minialarm sounder may be secured to any flat
surface by inserting two mounting screws through the back of
the round base (see figure 3). The enclosure provides IP65
protection and is suitable for installation in exterior locations
provided that the area around the two mounting screws
through the back of the base moulding has been sealed and
that suitable cable glands with the required IP rating have
been used.
5.2 Installation procedure
a. Unscrew the sounder unit security screw and remove
the sounder section from the base by turning it anti-
clockwise. Ensure that the ‘O’ ring seal remains in
place.
b. Remove the required 20mm knockout section(s)
depending on system wiring and mount the base to a
flat surface by inserting two screws through the back
of the base.
c. Fit the required number of 20mm cable glands or
conduit entries into the base and connect the field
wiring to the appropriate sounder terminals as shown
in section 6 and fig 2 of this manual. The power supply
terminals + and - are duplicated so that sounders may
be connected in parallel, or an end of line monitoring
resistor may be fitted.
d. Select the required output tone by positioning the six
switches as shown in Table 1 and Fig 2.
e. Apply power to the sounder and adjust the internal
volume control to provide the required sound level.
f. Check that the ‘O’ ring seal is correctly located on the
sounder section (see Fig. 2) and insert the sounder
section into the base. Push it fully home and turn it
clockwise to align the mouldings before tightening the
security screw.

6) Electrical System Design For Installation In
Hazardous Areas Using Zener Barriers
6.1 Single stage alarm
If the control switch is in the positive supply, or the power
supply is being turned on and off, only a single channel Zener
barrier is required as shown in Fig 4. This circuit may also be
used if the sounder is being controlled by a mechanically
activated switch on the hazardous area side of the barrier.

two stages of alarm are required the third stage barrier
should be omitted, the 28V 93mA barrier and the single diode
return channel may then be contained in one package.

7) Electrical System Design For Installation In
Hazardous Areas Using Galvanic Isolators
Galvanic isolators do not require a high integrity earth
connection. For small systems where a high integrity earth is
not already available, the use of galvanic isolators often
reduces the overall installation cost and simplifies design.
7.1 Single stage alarm
The IS-mA1 minialarm sounder may be powered by any
galvanic isolator having output parameters within the limits
specified in section 4.3, which has been certified Ex ia by an
EC Notified Body. The sounder may be controlled by turning
the galvanic isolator on and off, or by a mechanically
activated switch on the hazardous area side of the isolator.

8) Cable Parameters
The maximum permitted cable parameters are as specified
on the certificate of the Zener barrier or galvanic isolator that
has been selected for the installation. Normally the limits are
not restrictive, but care should be taken not to exceed a
capacitive limit of 83nF for installations when very long cables
are used.
9) Volume Control
The output level of the IS-mA1 sounder can be set by
adjusting the volume control potentiometer (see Fig 2).
10) Maintenance
The sounder should be regularly inspected to ensure that it
has not been damaged. Frequency of inspection depends
upon environmental conditions, but initially we recommend
that this should be done annually.
No attempt should be made to repair a faulty ISmA1
sounder. Suspect sounders must be returned to
European Safety Systems Ltd. or to your local agent for
repair.
11) Guarantee
Sounders that fail within the guarantee period should be
returned to European safety Systems Ltd. It is helpful if a
brief description of the fault symptoms is provided.
12) Customer Comments
European Safety Systems Ltd. is always pleased to receive
comments from customers about our products and services.
All communications are acknowledged and whenever
possible, suggestions are implemented.
