ELK AEXIN Alarm Engine 16-Zone Input Expander, LED, 4-Wire

Scale your security and monitoring infrastructure quickly and reliably with the ELK Products AEXIN Alarm Engine 16-Zone Input Expander. This control panel module adds 16 EOL resistor supervised hardwired zones to the Alarm Engine platform and operates over the standard 4-wire data bus, enabling up to seven expanders for a total of 128 zones. Selectable EOL resistor values (1.0K, 2.2K or 3.3K) provide wiring flexibility for a wide range of sensors and supervised loops.

Designed for professional installers, the AEXIN features plug-in terminal strips, status and diagnostic LEDs, and DC power plus battery connectors to simplify power and backup battery integration on commercial and residential projects. An onboard Form C relay offers straightforward integration with automation, CCTV triggers or third-party signaling equipment. With vertical mounting glides included and on-board EOL termination, the module reduces installation time and ongoing maintenance for security integrators.

Ideal for alarm, access control, surveillance and facility monitoring applications, the ELK AEXIN delivers dependable, expandable zone capacity for complex installations. Add it to your next Alarm Engine deployment to increase supervised input coverage—order today to streamline installation and enhance system monitoring.
