Product 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.

Features:

·    Single input for connection to dry contact inputs
·    Monitors and signals three distinct input states: Normal; Alarm; Open-circuit
·    Separate indicators for Quiescent, Alarm and Fault conditions
·    Polling indicator shows quiescent operation
·    DC 24 V operation
·    DIP switch address setting
·    125 usable detector address settings per loop
