Floodline® MDD-L32/T Visual Indicator provides monitoring of up to 32 detectors operating in a digital gas detection system as well as controlling other executive and signalling devices through contact outputs. Up to 7 Visual Indicators can be combined.
Communication with the MDD-256/T master control module is via industry standard RS485, in accordance with the Modbus RTU protocol.
The unit has a simple, fast display of up to 32 detectors in the digital gas detection system. The display indicates power supply, alarm and state of emergency for each individual detector through 32 sets of 5 LED lamps as well as contact states of control outputs OUT1, OUT2, OUT3 and OUT4.
12V alarm outputs control acoustic and optical sirens. There are four standard modes of operation divided over zones.
Contact outputs can operate fans, motors, contactors, information boards or connect with building and plant automation. The system can be configured to individual customer requirements.
The system has a very simple, intuitive launch with standardised properties and settings. The housing is adapted for mounting on TS35 rail in a standard electrical switchboard. Configuration of the module settings can be set up manually through the MDD-256/T master control module or alternatively with special configuration software on a PC.
