The range of MAD-400 modules has been developed to offer a wide and complete range of input and
output ports to be used with Detnov’s addressable fire control panels.
The MAD-400 modules allow performances and manoeuvres for the proper functioning of the fire
detection system, monitoring and/or acting according to the needs of the installation.
The MAD-400 modules have been designed to facilitate their installation process and they may be
installed using screws or fitted into a DIN rail. Each module is equipped with removable terminal
blocks and a LED status indicator. The addressing of the modules ir carried out through the PGD-200
programmer or auto addressing for isolator version.
The MAD-421 module provides 1 technical input and 1 free voltage relay output; the MAD-422 provides
2 technical inputs and 2 free voltage relay outputs. Inputs can be used to monitor any event that want
to have controlled and outputs can be used as a peripheral actuator to the fire detection system. In all
cases the modules act independently, being possible to assign specific manoeuvres to each of the inputs
The MAD-421 and MAD-422 modules take the power supply directly from the loop and assigned a
number of loop addresses according to the number of inputs available in the module.
The MAD-421-I and MAD-422-I modules are equipped with integrated isolator.
All the range of MAD-400 modules can be installed inside the BOX-ONE and BOX-SIX boxes.
