The ELSIR-10CM Ceiling Speaker features a 10W Class D amplifier,
utilizing all the power that PoE is capable of. This means that the
speaker is capable of delivering up to 96dB SPL (1m), depending on the
signal input. The ceiling speaker is designed to be mounted in cut outs
in tiles or plasterboard, and is ideal for providing audio to indoor
environments where speakers need to be discreet.
The built-in microphone enables new features such as Self-checking,
Automatic Volume Control, Ambient Listening, as well as two-way speech
via the speaker.
With IP, the system is able to monitor and address each speaker
individually. By moving the amplifier from a central unit out to the
speaker itself, the need for a central amplifier unit with conventional
speaker loops is eliminated. This makes the system highly scalable, and
adding another speaker is easy to do.
Even though conventional speaker loops are not used, the speakers can
still be divided into groups. These zones can now extend over networks
or span the Internet.
To provide maximum availability, the speaker comes with advanced
supervision functions. The speaker line test will detect whether there
are any faults in the network or speaker electronics. The status of the
speaker is reported to the central unit as well as to 3rd-party
management systems using SNMP or Syslog.
The speaker is also Auto-discoverable, and can receive messages from, and use Talkback directly to a VMS over ONVIF.
The speaker has a built-in web interface for status information,
control, and upgrade. It is easy to install and maintain. In addition,
there are possibilities where broadcasts can be logged in detailed
reports.
