ACC-EM-BUS - DATA SHEET

Product Overview

The X-PoE Emergency Bus Board is a DIN rail-mounted bus connection block that consolidates the emergency override inputs of up to eight X-PoE switches into a single trigger relay. It provides a clean, organized wiring solution that ensures all connected switches respond simultaneously during emergency events, eliminating the need for individual relay connections. A built-in pass-through port allows multiple emergency bus boards to be easily linked for larger systems, making it a simple and scalable solution for coordinating emergency override across X-PoE installations.

X-PoE Switch Connection

When wiring the emergency bus board to X-PoE switches, it is important to maintain proper pin-to-pin continuity between the emergency override terminals. The conductors must be arranged so that pin 1 connects to pin 1 and pin 2 connects to pin 2. This ensures consistent polarity and proper operation of the override input across all connected devices.
