ELK AEXOU Alarm Engine 8-Relays Output Expander, LED, 4-Wire

Add scalable, supervised relay outputs to your ELK Alarm Engine with the ELK Products AEXOU 8-Relay Output Expander. Designed for security integrators and facilities managers, this output expander provides eight Form C relay outputs per module to control auxiliary devices such as door locks, strobes, HVAC interlocks and automation points. It operates over the Alarm Engine’s 4-wire data bus for seamless, plug-and-play expansion and supports up to three modules (32 total outputs) for larger surveillance and monitoring deployments. With DC power and battery connectors onboard, you can easily connect a remote power source or backup battery to maintain critical outputs during power interruptions. Installer-focused features—plug-in terminal strips, a vertical mounting glide kit, status/diagnostic LEDs and an onboard EOL bus termination jumper—cut installation time and simplify troubleshooting. Ideal for commercial and residential alarm control panels, the AEXOU enhances system flexibility and resilience for security, monitoring and access control projects. Add this ELK control panel module to your next installation to expand outputs and streamline maintenance.
