626 analogue addressable single input/output modules provide the interface to connect an electrically isolated dry-contact switched input to Numens 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.
The range includes a model with an integral isolator that protects other devices connected to the same transmission path. The isolator activates in the event of a short circuit in the loop wiring.
The 626 input/output module provides fire detection and alarm system designers with a Standards-compliant, premium product for life safety and property protection applications.
