626 analogue addressable single input modules provide the interface to connect an electrically isolated dry-contact switched input to Numens addressable fire detection control and indicating equipment.

One model uses a parallel resistive input filter, allowing 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. A companion model includes 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 module provides fire detection and alarm system designers with a Standards-compliant, premium product for life safety and property protection applications.
