Addressable Sounder with Isolator

Referencia: MAD-461-I

Description

The range of MAD-400-I 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-461-I and MAD-462-I analogue sounders are designed to be used with DETNOV's analogue fire control panels. The MAD-461-I provides and acoustic signalling while MAD-462-I provides optical-acoustic signalling, both to the fire detection system. The sounders are directly connected to the loop and they must be addressed through the PGD-200 programmer. Each sounder takes up 1 address in the loop.

Due to its novel design, current consumption has been reduced to 7 mA. Installing up to 50 sounders per loop is possible due to low current consumption.

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. 

Features

     Compatible with DETNOV’s fire control panels
     Addressable sounders
     Low current consumption
     Two-wire connection with non-polarity
     Loop-powered device
     Connections through removable terminal blocks, and simple fitting of the cable
     EN54-3 and EN54-17 approved

Aplications

Analogue sounders are used to warn people in a building to start the evacuation procedure in the event of an alarm. They are the basic elements for warning people in any fire detection system installation.
