ELK M1 Series 16-Zone Input Expansion Module

The ELK Products M1 Series 16-Zone Input Expansion Module is a professional-grade zone expansion solution designed to increase the input capacity of ELK M1 Gold and M1EZ8 security and automation control systems. Commonly used in advanced residential, commercial, and industrial security installations, this module adds 16 additional hardwired zones for connecting sensors, contacts, detectors, and other supervised input devices throughout a facility.

Engineered for seamless integration with the ELK M1 platform, the input expander communicates directly over the ELK RS-485 data bus, allowing flexible remote installation and scalable system growth without extensive rewiring. The module supports a wide variety of security and automation devices including door and window contacts, motion detectors, glass break sensors, smoke detectors, water sensors, panic devices, temperature sensors, and other low voltage monitoring equipment.

Designed for reliability and installation efficiency, the ELK M1 Series 16-Zone Input Expansion Module features onboard zone status LEDs, programmable zone definitions, and supervised input capability for enhanced system monitoring and troubleshooting. Multiple expanders can be added to a single ELK M1 system, making it ideal for large homes, office buildings, warehouses, schools, churches, and integrated smart building environments requiring expanded security coverage.
