series 60 detectors for use in hazardous areas

PP2028/2001/Issue 4
SERIES 60 DETECTORS FOR USE IN
HAZARDOUS AREAS
The Series 60 range of smoke and heat detectors
has been extended to include intrinsically safe
versions, specifically developed for use in
hazardous areas.
AVAILABILITY
An ionisation smoke detector, integrating
ionisation smoke detector and five grades of heat
detector are available.
FUNCTION
The Series 60 I.S. detectors are functionally
equivalent to their standard Series 60
counterparts. They differ in design only in that
their circuits and construction have been
modified to conform to the requirements of EN
50014:1977 and EN 50020:1977 (which are
identical to BS5501:Part 1 and BS5501:Part 7
respectively).
All types are certified EEx ia IIC T5 at ambient
temperatures up to 40°C or T4 at ambient
temperatures up to 60°C.
The BASEEFA certificate number, applicable to all
types, is Ex96D2439.
MECHANICAL CONSTRUCTION
Series 60 I.S. detectors use the same outer casings
as the standard Series 60 detectors, and therefore
share the same dimensions. The detectors are
identified as intrinsically safe by a printed legend
around the lid (see photo above).
The detectors must be used with the certified
Series 60 I.S. base which is considered for
certification purposes to be part of the detector.

The base is marked with the legend ‘PART OF
BASEEFA CERTIFIED DETECTOR’. Use of any other
base will invalidate the approval.
SYSTEM REQUIREMENTS
The detectors must be used in a system which
includes suitable safety barriers and which is
certified by BASEEFA or other competent body.
Apollo Fire Detectors has obtained system
certification for a system incorporating any of the
following safety barriers:
Any certified 28V/300Ω shunt safety barrier
MTL3043 or MTL4061
Pepperl + Fuchs KHD0-ICS-Ex151 or Ex251
Pepperl + Fuchs KHD0-CS-Ex1.54 or Ex2.54
Pepperl + Fuchs KFD0-ICS-Ex151 or Ex251
Pepperl + Fuchs KFD0-CS-Ex1.54 or Ex2.54
(Apollo part no 29600-098)
ELECTRICAL CHARACTERISTICS
The following characteristics apply at 24 V DC
and 25°C unless otherwise stated:
Supply voltage
(quiescent)
Quiescent current
Ionisation detectors
Heat detectors
Alarm load
The BASEEFA system certificate number is Ex97D2054.
The system certification allows up to 20 Series 60
I.S. detectors to be connected to a single barrier
circuit with an end-of-line resistor of not less than
1.8kΩ. However, it must be ensured that the
voltage available at each detector is above the
minimum specified in the quiescent condition. It
is also important to ensure that the alarm load is
suitable for the control and indicating equipment.
The system certification also allows the use of
remote LED indicators. These may be
connected to individual detectors or may use a
connection common to two or more detectors
as shown below:
Note: Series 60 IS detectors are polarity sensitive.
When a remote indicator is
used L1 must be connected
to the positive line in

INSTALLATION GUIDELINES
The detectors must be installed in accordance
with the appropriate local code of practice e.g.
BS5435 in the UK. The following points should be
noted in addition:
It is important that detectors are installed in
such a way that all terminals and connections
are protected to at least IP20 when the detector
is in the base. If the base is mounted on a
conduit box with a diameter of less than 85mm
then the base should be fitted with the Series
60/XP95 Backplate, part number 45681-233.
The base contains an earth terminal which is
provided simply as a convenient termination
point for cable screens. It is not essential for
the correct operation of the detector and is not
intended to be used for a safety (I.S.) earth.
APPROVALS
Series 60 I.S detectors have been approved by
LPCB to EN54. They have also been approved for
marine use by the following bodies:
