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
Power consumption: 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.
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 indicator should be installed in corridors or access
pathways to the corresponding building sections or rooms.

in malfunction and damage to the remote indicator.
