Description  
The addressable Module M221E serves for the line-  
monitored integration of 2 contact detectors, such as  
manual call points, sprinkler system contacts or super-  
vising contacts, into the bidirectional communication  
on the ADM loop with System Sensor/200 protocol.  
Furthermore, it can be used to actuate external de-  
vices by means of a relay output with a dry change-  
over contact, via the ADM loop. Each input as well as  
the output have individual status LEDs. Separate termi-  
nals enable the operation of the module with or without  
the integrated dual-isolator.  
Accessories for mounting on a wall, on a plate or on a  
DIN rail are available.
