Figure 1: Wall-mounted MX43 and examples of the modules. 
The system primarily comprises: 
 
■  a wall-mounted MX43 (4 or 8 lines) or rack-mounted MX43 (8 lines); 
■  different modules (detector with digital or analog output, logic inputs, 
analog inputs, relay outputs, and analog outputs). 
The MX43 instantly handles the measurements of detectors and input 
modules. As soon as the measurements reach the programmed limit, a sound 
and visual alarm are given. At the same time, the corresponding relay or 
relays are activated, in turn controlling the additional internal or external 
actions envisaged by the user. 
 
The measurement unit is programmed by using the COM43 application.
 
Figure 2 presents a configuration example.
