Isolator Detector Base XP95
AISA-45681-321
Description
Specifi cations
The Isolator Detector Base AISA-45681-321 is desig-
ned to accommodate intelligent fi re detectors Series
XP95 and Discovery for use in ADM loops with Apollo/
Discovery protocol.
A dual-isolator unit is integrated into the detector base,
which reliably disconnects the loop in case of a short
circuit. With the dual design, the input side or the output
side isolator – depending on the location of the short
circuit – interrupts the connection to the faulty loop
segment. Therefore the detector remains in operation.
A yellow status LED, which is integrated into the base,
shows a steady light in case of a short circuit of the
loop.
Due to its robust multi-wire screw terminals, the detec-
tors can be wired with ease, thus achieving a secure
and durable connection. The base also provides a pos-
sibility for the easy connection of remote indicators.
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 dry
rooms. For special applications a range of accessories
(for moist room, false ceiling or fl ush installation) is avai-
lable.
A mechanical theft protection of the detector can
optionally be activated at the detector base.
