Heat detector WMX5000FS
2.9.7.1 Notes
Only one detector may be connected to a detector zone. Furthermore, the end-of-line resistor of the con-
ventional line must have 3.3kOhm. The WMX5000 is a high temperature detector whose alarm
threshold can be selected (with DIP switches in the base – for further information in this regard, please
refer to the manufacturer's documentation).
The detector is powered by the detector zone and signals its condition through the 2 lines:
Alarm line (latching, can be reset by de-energising the detector zone)
Fault line (optional, separate detector zone required)
If a fault line is used, the following is to be taken into account:
Upon disablement of the alarm line, the fault line will be activated.
In the case of alarm verification of the alarm line, the fault line will be activated while the alarm line
is disabled.
2.9.7.2 Connection
Make sure that the connection cable is sufficiently temperature-resistant.
You must not connect more than one detector to a detector zone with Rab = 3.3kΩ. Detector zones
with Rab = 5.6kΩ or Cab = 47µF are not suitable. Therefore the device is only compatible with the
BC016 and the BC600 (GIF608-1).
