5.4 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 upper detector section, from contamination.
The protective dust cover made from polypropylene (PP) is
pushed onto the installed detector base.
5.5 WA400 Detector Console
The WA400 Detector Console is used to install detectors
above door frames or similar in compliance with DIBt.
The console is supplied with a pre-mounted MS400
Detector Base (the detector shown is not included in the
scope of delivery).
5.6 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
Resistor: 1kΩ
Maximum power dissipation: 3W.
The heating is supplied with power either by the looped-
through supply voltage via the control panel or by a separate
power supply unit.
With supply via the control panel, the number of detector
heating elements depends on the cable cross section and
cable length used.
5.7 Remote Indicators
A Remote Indicator is required if the detector is not directly visible or has been mounted in
false ceilings or floors.
The remote indicators should be installed in corridors or access pathways to the
corresponding building sections or rooms.
Wiring
For connection to the standard bases MS400/MS400B note the following:
