Product Description:

This ELK Alarm Engine 16-Zone Input Expander is a highly flexible and powerful component for your security system’s enhancement, which is aimed at adding more signals to your setup. It has zone 0-15 EOL resistor supervised hardwire zones for efficient monitoring so that the system is highly reliable. The expander has an externally accessible Form C relay output for the expansion of other functions and control. It has a DC power and battery connections keep power constant, making it possible for the device to remain functional during a power outage. Using a 4-wire data bus, the expanders make installation of this product quite easy and enhance the communication between the main alarm panel and the expander. As for the connections, there are plug-in terminal strips that make connections fast, effective, and secure. With built-in LED indicators for status and diagnostics provides immediate visual feedback on performance.
