of up to 20 IS detectors 2840 and 2841. It is mounted in a
Waterproof box (IP66/67). Five compression glands for the
cable entries are supplied. Box dimensions (L x W x H): 280 x
280 x 133 mm. ATEX class: Ex ia IIC.
9.1.5.2
Intrinsically Safe mounting bases
YBN-R / 4 IS
Intrinsically Safe mounting base (2812). In the
base can be plugged an intrinsically safe conventional smoke
(2810) or heat (2811) detector. The base has terminals for the
zone line (in/out) and for an ext. LED.
9.1.5.3
Intrinsically Safe photoelectric smoke detectors
SLR-E-IS
Intrinsically Safe photoelectric smoke detector (2810).
A conventional photoelectric (optical) smoke detector, shall 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. Zone classification: Cat. 1, 2 or 3.
BASEEFA classification: II 1G EEx ia IIC T5 (-20°C < 55°C).
Max 20 per zone.
2840
Analog IS smoke detector.
40
An analog / addressable photo-
electric smoke detector. The detector is supplied with a back-
box and three cable glands. The detector has one built-in LED
to indicate that the detector has generated fire alarm. The
function is similar to the analog photoelectric smoke detector
4301, see page 43. It has to be connected to a COM loop via an
IS barrier unit 2842. ATEX class: Ex ia IIC T5.
9.1.5.4
Intrinsically Safe heat detectors
DCD-1E-IS
Intrinsically Safe heat detector. A conventional Rate of
Rise heat detector, fixed temperature 60°C (class A1), shall 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: Cat. 1, 2 or 3. BASEEFA
classification: II 1 G EEx ia IIC T5, T
amb
=55°C. Max 20 per
zone.
2841
Analog IS heat detector.
40
An analog / addressable heat
detector. The detector is supplied with a back-box and three
cable glands. The detector has one built-in LED to indicate that
the detector has generated fire alarm. The function is similar to
the analog heat detector 3308, see page 41. It has to be
connected to a COM loop via an IS barrier unit 2842. ATEX
class: Ex ia IIC T5
9.1.6
Other COM loop units
3366
External power supply. Conforms to EN54-4. 3366 is
connected to a COM loop, i.e. it is monitored from EBL512 G3
and e.g. loss of the main power source will generate a fault in
EBL512 G3. It can be used as power supply for external
