MAD-490

Addressable short-circuit protection isolating module, with status LED, which isolates the loop section between two isolators in the event of a short-circuit in the loop. Takes no address in the loop. Direct feed from the loop. Connection through removable strips up to 2.5mm2 section. Possibility of being installed in DIN rail or flat to wall mounting in box BOX-ONE. Consumption less than 300μA at rest. Red color. Dimensions: 100 x 82 x 23 mm. CPR certificate EN54-17.

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. This module does not require any addressing. The MAD-490 module protects the system from short circuits in the loop. Its function is to disconnect he loop section between the 2 isolators that are nearest to the short circuit, allowing the rest of the installation to work without trouble. The MAD-490 take the power supply directly from the loop and does not get an address from the loop. All the range of MAD-400 modules can be installed inside the BOX-ONE and BOX-SIX boxes.
