Description
•   ADM loop technology with
System Sensor/200 protocol
•   Monitored analogue input with 
sensing range 4 – 20mA
•   Connection of analogue sensors such
as gas detectors or fl ame detectors
•  Current-limited sensor circuit
•   Mounting by means of
Surface Mounting Box SMB500
The  Monitor  Module  M510E-4-20  is  designed  for  the 
connection  of  analogue  sensors  with  a  4  –  20mA 
 current interface.
With that, all sensors that are equipped with a corres-
ponding analogue output – for example, gas detectors 
or fl ame detectors – can be integrated into a fi re detec-
tion system. By means of the module, sensors in 2- or 
3-wire technology can be connected.
The sensor circuit is powered by connecting an exter-
nal power supply to the module. The integrated current 
limiter prevents overloading of the module if the power 
supply for the sensor is short-circuited. In addition, the 
current-limited  analogue  input  is  monitored  for  wire 
 breakage.
The  Monitor  Module  M510E-4-20  is  integrated  into 
an  ADM  loop  with  System  Sensor/200  protocol  and 
 occupies one address in the number range of detector 
addresses.
The  two-coloured  status  LED  is  actuated  by  the  fi re 
 detection control panel and indicates the activated con-
dition and fault condition of the sensor.
The  module  is  designed  for  mounting  in  a  Surface 
Mounting Box SMB500.
