SHIELD S-A4050 Relay Output Module

The SHIELD S-A4050 is an addressable relay output module designed to control third-party auxiliary equipment via a fire alarm loop interface. Functioning as a high-performance control interface within an addressable fire safety system, this module contains potential-free changeover relay contacts capable of switching external building automation equipment such as access control doors, smoke ventilation dampers, elevator recall, and auxiliary signaling devices. Connected directly to the communication loop, the S-A4050 offers fast execution times, programmable output logic from the main panel, and continuous monitoring of device status via onboard LED indicators. With soft-addressing capability and low standby current consumption, the S-A4050 ensures reliable automated control for building protection and life safety integration.
