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 CAD-150 family of analogue fire control panels. These modules let you manage a wide variety of situations, by monitoring and acting according to the installation's requirements.

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 is carried out through the PGD-200 programmer.

The MAD-411-I and MAD-412-I modules provide 1 and 2 free contact relay outputs to the fire detection system. These contacts usually switch some peripheral circuits on and off. In the case of having two contacts, they can operate independently and specific programs can be assigned independently to them. The MAD-411-I and MAD-412-I modules take the power supply directly from the loop.

The isolator  protects the system from short circuits in the loop, and its function is to disconnect the loop section between the 2 isolators that are nearest to the short circuit, allowing the rest of the installation to work without trouble. 

■     Simple installation on the wall or fitted into a DIN rail
■     Non-polarity supported
■     Addressing through a programmer
■     Stable communication protocol with immunity to noise
■     Loop-powered device
■     Connections through removable terminal blocks, and simple fitting of the cable
■     EN54-18 and EN54-17 approved

The MAD-411-I and MAD-412-I modules are ideal for switching any device on and off, and they are also ideal for integration with other systems that can be managed through a relay contact, such as ventilation stoppage, elevator stoppage or discharge system activation.
