User Experience
The Wahsega 2x2 Ceiling Speaker with SIP may look like a standard 2x2
ceiling tile speaker, but it can receive audio from multicast IP broadcasts or
from a SIP PBX, and it can act as an intercom for two-way conversations
with the help of its built-in microphone.
The speaker may also be connected to a panic button to make emergency
SIP calls and/or to a remote wall panel to access classroom sound
reinforcement functions. Its two onboard relays can be controlled
remotely to operate door locks for up to two doors per classroom.
In addition, a second, auxiliary speaker may be connected up to 20 meters
away via Ethernet cable. This auxiliary speaker—which is powered by the
first speaker—can be either in the same classroom as the primary speaker
or in a separate classroom. Although powered the same way, these two
applications function differently.
In a single-classroom application, the auxiliary speaker acts as a
companion to the main speaker. The auxiliary speaker’s volume can be
adjusted independently, but it will always broadcast the same audio as the
main speaker. In this application, the primary speaker controls features
such as door locks, microphone, panic button and sound reinforcement.
In a two-classroom application, the auxiliary speaker has its own SIP
account, enabling it to send and receive audio independent of the main
speaker. It functions separately from the primary speaker, controlling door
locks, microphone, panic button, and sound reinforcement of its own. To
an end user, the auxiliary speaker appears to be completely autonomous;
it is simply powered by the primary speaker.
