Telecor 1SO324 ESBM-TB Speaker Breakout Module

The Telecor 1SO324 ESBM-TB Speaker Breakout Module is a Telecor eSeries interface that enables integration of conventional analog speakers and call stations with an IP intercom and public address system for paging, talkback, and emergency communication. Commonly installed in schools, educational campuses, healthcare facilities, commercial buildings, and institutional networks, it lets 8 Ω, 25 V, and 70 V analog speakers—including Telecor eSTB-12 via CAT5—operate within Telecor's IP-based paging and emergency channels. Key specifications include HD digital audio transmission, a 50 Hz to 7 kHz frequency response, Ethernet with Power over Ethernet (PoE) support, and three programmable relay outputs for automatic control functions. It supports paging, talkback, emergency paging, and public channel operation, works with Telecor eCS call stations and standard push-button switches, and is configurable through the Telecor ePort Management Interface and eCI Control Interface as a genuine Telecor eSeries module (part number 1SO324, model ESBM-TB).
