Detector Base Sounders - Bosch AVENAR 4000 FAP-425-O User Manual

AVENAR detector 4000
SK 400 Protective Basket
The SK 400 Protective Basket is installed over the detector
and gives the detector substantial protection against
damage.
If the detector is mounted in a sports facility, for example,
the protective basket prevents balls or other sports
equipment from hitting the detector and damaging it.
SSK 400 Protective Dust Cover
The SSK 400 Protective Dust Cover is necessary during
construction work to protect an installed detector base,
with or without detector module, from contamination. The
protective dust cover made of polypropylene (PP) is pushed
onto the installed detector base.
WA400 Wall bracket
The WA400 Wall bracket is used to install detectors above
door frames or similar in compliance with DIBt.
The bracket is supplied with a pre-mounted detector base
(the detector shown is not included in the scope of
delivery).
MH 400 Detector Heating Element
The MH 400 Detector Heating Element is required if the
detector is used in an environment where water
condensation can occur, such as in a warehouse that must
frequently be opened briefly for delivery vehicles.
The detector heating element is connected to the + V/0 V
terminals in the detector base.
Operating voltage: 24 V DC
Resistance: 1 kΩ
Maximum power dissipation: 3 W.
The heating is supplied with power either by the fed-
through supply voltage via the central unit or by a separate
power pack.
With supply via the central unit, the number of detector
heating elements depends on the cable diameter and line
length used.
