E2S IS-pA1 Instruction Manual

1)

Introduction

The IS-pA1 is an ATEX and IECEx certified intrinsically safe
Panel Mount Sounder which can produce a loud warning
signal in a hazardous area. The sounder has been designed
to operate in gas groups IIA and IIB via ATEX and IECEx
certified Zener Barriers or Galvanic Isolators. The sounder
may be tested or used in safe areas without using a Zener
Barrier or Galvanic Isolator,

Intrinsic Safety Certification

2.1 ATEX and IECEx certificates

SIRA 10ATEX2137
Ex ia IIB T4/5/6 Ga (-40ºC ≤ Ta ≤ +60ºC)
II 1G
The IS-pA1 sounder complies with the following standards:-
EN IEC 60079-0:2018
EN60079-11:2012
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 standard EN60079:14:2008 Electrical Installation
in Hazardous Areas. When designing systems for installation
outside the UK, the local Code of Practice should be
consulted.

it is resistant to specific chemicals.

2.2 Zones, Gas Groups and Temperature Class

The IS-pA1 sounder has been certified Ex ia IIB T4/5/6 and
when connected to an approved system it may be installed in:
Zone 0
Sheet 1 of 2
Intrinsically Safe
The equipment has
parameters:-
Ui = 40V Ii = 660mA
Li = 0 Ci = 32.5nF
With respect to Temperature Class the following
limitations on maximum input power P
applicable:
Temperature Class
T1, T2, T3, T4
T5
T6
The equipment is only certified for use in ambient
temperatures in the range -40
not be used outside this range.
Installation of this equipment shall only be carried
out by suitably trained personnel in accordance with
the applicable code of practice e.g. IEC 60079-14 /
EN 60079-14.
Repair of this equipment is not possible and shall
not be attempted.
The equipment has not been assessed as a safety-
related device (as referred to by Directive 94/9/EC
Annex II, Clause 1.5).
The certification of this equipment relies on the
following materials used in its construction:
Enclosure:
ABS
Encapsulation:
Polyurethane casting compound
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
adversely affected, thus ensuring
from being
that the type of protection is not compromised.
"Aggressive substances"
gases that may attack metals, or solvents that may
.
affect polymeric materials
explosive gas air mixture
