IP Horn Speaker


The IP-A1SC15 is an IP paging horn speaker to deliver clear announcements via network with 124 dB output capability powered by PoE+ power source. Its rugged enclosure is IP66 rated for outdoor environments. The IP-A1SC15 supports common network protocols for easy integrations with Video Management Systems and other SIP-compatible VoIP systems and devices. Group paging function is available with 20 Multicast ports for zone paging requirements. Internal sound source file storage allows storing pre-recorded messages or tones which can be played back by 2 control inputs or Remote API (HTTP).
