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.
