Telecor Inc. 1SO344 ESBM-TB Speaker Breakout Module

The Telecor Inc. 1SO344 ESBM-TB Speaker Breakout Module is an interface that lets conventional analog 8 Ω, 25 V, or 70 V speakers and call-initiating devices join a Telecor eSeries IP intercom and public address system, delivering paging, talkback, and emergency communication. Designed for Telecor eSeries Intercom and Paging System networks, it uses Ethernet with Power over Ethernet (PoE) and provides HD digital audio with a 50 Hz–7 kHz frequency range and up to 128 kbps of audio bandwidth during active communication. The module supports Telecor eSTB-12 speakers via CAT5 as well as standard 8 Ω, 25 V, or 70 V speakers, and offers three programmable relay outputs for automatic control functions. Call stations from the Telecor eCS series and standard push-button switches are compatible, enabling seamless integration of legacy devices with modern IP-based systems. Configuration is simplified by automatic network discovery with no manual network setup required, and the unit is a genuine Telecor eSeries module intended for system expansion, retrofit projects, and facility upgrades across schools, healthcare facilities, campuses, and commercial buildings.
