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-421-I module provides 1 technical input and 1 free contact relay output, and MAD-422 provides 2 technical inputs and 2 free contact relays outputs. The inputs can be used to monitorize any external event to the fire system, and the outputs can be used to switch some peripheral circuits on and off. In any case, all inputs and outputs operate individually, providing a broad range of configuration options. Both devices are powered directly from the loop.
Technical inputs can be configured through a micro-switch to operate as NC or NO, and there is the option to select between supervised and non-supervised input.
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 block, and simple fitting of the cable
■ EN54-18 and EN54-17 approved
The MAD-421-I and MAD-422-I modules are usually installed to supervise NO or NC contacts or to integrate with other systems that can be managed through a free contact relay.
