IS Thermal Detector AWEX-55000-440
The addressable Intrinsically Safe Thermal Detector
AWEX-55000-440 (fi g. B) uses the heat principle and
was developed for the fi re detection in hazardous
areas. The heat detector must always be connected
via a safety barrier, which has been approved for this
detector, and a protocol interface. Furthermore, the re-
levant country specifi c regulations always have to be
observed.
The detector is assigned to Class A2S and can be used
up to a room height of 6m. Depending on the parameter
setup in the fi re detection control panel, the detector
can operate either as maximum heat detector with an
alarm temperature of 55°C, or as rate-of-rise heat de-
tector with a maximum temperature of 55°C.
The proven ADM loop technology with Apollo/Discovery
protocol establishes a permanent communication bet-
ween the fi re detection control panel and the detector.
That ensures a periodical function testing of the detec-
tor. Fires are safely detected in the control panel by
continuously analysing the measured values.
The two LEDs with 360° visibility indicate the activated
condition of the detector. The detector address is se-
lected by means of a code card in the detector base.
Therefore the detector can be changed without additi-
onal tools.
The detector is inserted into the IS Detector Base ASEX-
45681-215 (not illustrated) and it can be protected
against theft.

IS Detector Base ASEX-45681-215
The IS Detector Base ASEX-45681-215 is designed to
accommodate intrinsically safe intelligent fi re detectors
Series XP95 for use in ADM loops with Apollo/Discovery
protocol.
Due to its robust multi-wire screw terminals, the detec-
tors can be wired with ease, thus achieving a secure
and durable connection.
The detector address is selected by means of a code
card in the detector base. Therefore the detector can
be changed without additional tools.
The base is designed for surface mounting in hazardous
areas. A mechanical theft protection of the detector can
optionally be activated at the detector base.
