ADR-741

Addressable Relay Module

The ADR-741 is an addressable relay module with dry contact relays, designed for actions like electricity disconnect or elevator recall via relay activation.

The ADR-741 is a vital component for executing specific actions such as electricity disconnect or elevator recall through its dry contact relays. Occupying a single address, the module’s non-volatile memory stores the address, programmable and verifiable, using the Addressable Detector and Accessory Programmer. The onboard indicating LED flashes when addressed by the control panel, providing clear activation feedback. Supervised by the control panel, the ADR-741 communicates via the SLC, ensuring seamless integration with a full range of addressable control panels.
