Fire alarm systems
Units for Hazardous (Ex) areas
• Approved isolator and Intrinsically Safe detectors for conventional zone line input.
General
In hazardous (Ex) areas, Intrinsically Safe
(IS) and approved products are required. To
a zone line input is connected a Galvanic
isolator, to which the intrinsically safe
detectors are connected.
Galvanic isolator MTL5061
The isolator is used to connect the IS detectors and manual call points to a zone line
input. Up to 5 units can be used on the zone
line and an end-of-line resistor is to be
connected in the last unit. The isolator has
two in and outputs (Channel 1 & 2) and is
mounted in a waterproof box (IP66/67).
Supplied with four compression glands for
the cable entries, two 12K e-o-l resistors for
system EBL500 and two 10K e-o-l resistors
for system EBL128.
IS mounting base YBN-R/4 IS
In the base could be plugged a conventional
IS smoke or heat detector.
The base has terminals for the zone line
(in/out) and for an external indicator (LED).
IS smoke detector SLR-E-IS
A conventional IS photoelectric (optical)
smoke detector, to be plugged in the IS
mounting base.
The detector has two built-in LEDs to
indicate that the detector has generated fire
alarm.
IS heat detector DCD-1E-IS
A conventional IS Rate of Rise heat
detector, fixed temperature 60°C (class A1),
to be plugged in the IS mounting base. The
detector has two built-in LEDs to indicate
that the detector has generated fire alarm.
Product applications
The units are used in the systems EBL500
and EBL128 with conventional zone line
inputs available.
Connections, etc. according to connection
diagram for the system respectively.
