Audited Supplier Description
621 analogue addressable single input modules provide the interface to connect an electrically isolated dry-contact switched inputs to Numens 2-wire addressable fire detection control and indicating equipment.
A parallel resistive input filter allows multiple states to be monitored at the input. The states are converted to the loop communications protocol by the module, to enable them to be displayed on the control and indicating equipment.
