Units for Hazardous (Ex) areas

In hazardous (Ex) areas, Intrinsically Safe (IS) and approved products
are required. The IS alarm points are connected to a detector
interface, i.e. a Galvanic isolator, which is connected to an expansion
board 4580 zone line input. See also drawings 128-32.
Galvanic isolators
MTL5061 Galvanic isolator. The isolator is used to connect the IS
detectors and manual call points to an expansion board 4580
zone line input. The isolator has two zone line inputs and two
outputs (Channel 1 & 2) and it is mounted in a Waterproof box
(IP66/67). Four compression glands for the cable entries and an
end-of-line resistor (10K) with an area >230 mm
Box dimensions (L x W x H):
BASEEFA classification: EEx ia IIC.
Intrinsically Safe mounting bases
YBN-R / 4 IS Intrinsically Safe mounting base. In the base can
be plugged an intrinsically safe conventional smoke or heat
detector. The base has terminals for the zone line (in/out) and
for an ext. LED.
Intrinsically Safe photoelectric smoke detectors
SLR-E-IS Intrinsically Safe photoelectric smoke detector.
A conventional photoelectric (optical) smoke detector, to be
plugged in the intrinsically safe mounting base. The detector
has two built-in LEDs that are lit to indicate that the detector
has generated fire alarm.
BASEEFA classification: EEx ia IIC T5, t (amb.)=50°C. Max
20 per zone.
Intrinsically Safe heat detectors
DCD-1E-IS Intrinsically Safe heat detector. A conventional Rate of
Rise heat detector, fixed temperature 60°C (class A1), to be
plugged in the intrinsically safe mounting base. Two built-in
LEDs that are lit to indicate that the detector has generated fire
alarm. Zone classification: Category 1 (incl. lower categories).
BASEEFA classification: II 1 G EEx ia IIC T5, t (amb.)=55°C.
Max 20 per zone.
Intrinsically Safe manual call points

Other COM loop units

3366 External power supply. Conforms to EN54-4. The unit is
connected to a COM loop, i.e. it is monitored from EBL128 and
e.g. loss of the main power source will generate a fault in
EBL128. It can be used as power supply for external
