Quality Standards
Wahsega Labs products achieve the highest standards of
performance in the market by utilizing our complete quality
assurance program encompassing software testing, product design
and a multistage automated factory test program.
Wahsega Labs’ ultimate goal is to provide a solution that is both cost
effective and unsurpassed in quality. By leveraging existing
relationships with suppliers to guarantee premium components at the
lowest possible prices, we are able to ensure Wahsega Labs products
are the finest quality in the market while still offered at highly
competitive prices directly to installers.
In order to achieve the greatest possible voice clarity, all voice and
related algorithms have been individually tested to ensure the highest
potential MOS score. The accumulated error syndrome, which can
cause poor voice quality, is mitigated through this testing process.
Wahsega Labs’ engineering team utilizes a wide array of dedicated test
servers to pull and build the various software projects multiple times
per day. Each automatic build is then run through an extensive set of
automated test cases to ensure the highest performance of each and
every firmware version released. This test case coverage is expanded
on a continual basis.
All Wahsega Labs products are 100% factory tested at the board level
through a bed of nails full functional test, not just an “is it close
enough?” flying probe test. Every finished product is 100% tested again
after the final assembly via an automated test station to ensure the
highest production quality product for installers.
To assure the highest quality standards, all Wahsega Labs products are
designed, developed and manufactured in the USA.

User Experience
The Wahsega Surface Mount Wall Speaker with InformaCast may look like
a standard wall speaker, but it can receive audio from both the
InformaCast Advanced Notification System and a SIP PBX, acting as an
intercom for two-way conversations with the help of its built-in
microphone.
Featuring dual registration with both InformaCast and SIP servers, the
speaker is able to receive InformaCast pages in high- or low-quality
audio—both live and pre-recorded—while also supporting normal SIP
intercom calls.
The speaker may also be connected to a panic button to make emergency
SIP calls and/or a remote wall panel to access classroom sound
reinforcement functions. Its two onboard relays can be controlled by the
InformaCast server 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. Two different Wahsega auxiliary speaker models
can be used, depending on the application. The auxiliary speaker—which
is powered by the primary speaker—can be either in the same room as
the Wahsega Surface Mount Wall Speaker or in a separate room.
In a single-room application, the Wahsega Analog Speaker (WL-SPKR-SMT-
A or WL-SPKR-22-A) acts as a companion to the primary speaker. This
auxiliary speaker’s volume can be adjusted independently, but it will
always broadcast the same audio as the main speaker. In this application,
only the primary speaker supports features such as door locks,
microphone, panic button and sound reinforcement.

Surface Mount Speaker with InformaCast Page 8 v 1.8.1-20190215
In a two-room application, the Wahsega Second Room Speaker (WL-SPKR-
SMT-2R or WL-SPKR-22-2R) has its own SIP account and InformaCast
instance, enabling it to send and receive audio independent of the primary
speaker. While it receives its power and data from the primary speaker, it
functions separately—with the ability to control door locks, microphone,
panic button, and sound reinforcement on its own. To an end user, the
Second Room Speaker appears to be completely autonomous; it is simply
powered by the primary speaker.
Once your speaker is installed and configured, you will be able to receive
SIP calls and InformaCast broadcasts with no additional in-room setup.
Two-way communication is clear and simple with a built-in microphone
which transmits audio from the classroom to the caller.
If a panic button is connected to the speaker, it will make an emergency
call to a preset SIP number on the PBX. To reduce the incidence of false
panic calls, the panic button has two call modes: short press and long
press. The short press call—which is a call placed after the button is
depressed for any length of time less than two seconds—calls a first,
preconfigured number, such as a front office. The long press call—a call
placed after the button is depressed for two or more seconds—calls a
second, preconfigured emergency number, such as 911.
If the installation includes a sound reinforcement wall panel, the panel will
have an audio input, volume control, activate button and LED indicator
light.

Software Capabilities
The speaker’s configuration is accessible using an HTTP Web interface,
viewable from any Web browser on the same LAN. This allows access to
various settings such as network/IP address, SIP account and InformaCast
instance configuration, intercom/speaker behavior, panic button call
numbers, and administrative functions such as firmware upgrade and
configuration backup/restore. The configuration is stored in a .JSON file,
which is human readable and can be edited by site administrators.

Surface Mount Speaker with InformaCast Page 10 v 1.8.1-20190215
Getting Started
1. Connect the speaker’s main Ethernet port—labeled POE—to a network
using a Power-over-Ethernet (PoE) Ethernet connection. When
connected, it will power on immediately, and the LINK/ACTV status LED
will begin to blink.
2. Locate and note your speaker’s MAC address. It is printed as a QR code
on a white sticker on the front of the speaker. Simply scan the QR code
with a smartphone or tablet QR reader app, and it will give you the MAC
address for that speaker.
3. Your speaker will automatically recognize and register with the
InformaCast server when you power up and connect to the network via
PoE. Use the InformaCast server interface to discover your speaker’s IP
address. Look for the device matching the MAC address you just noted.
4. When you first connect your speaker’s Ethernet cable, the status LED on
the face of the speaker will blink slowly, indicating that it is trying to
discover its IP address. Once its IP address has been established, it will
blink faster, indicating that it is trying to register with InformaCast. It will
maintain a solid green state once it has successfully registered with the
InformaCast server.
5. Once you determine the speaker’s IP address, navigate to that IP
address in your Web browser (for example, http://123.456.78.9).

Surface Mount Speaker with InformaCast Page 11 v 1.8.1-20190215
6. When you access the webpages, the speaker will ask for a username
and password. The default username and password are admin and
admin.
7. On the right side of the page is the Status bar. It shows the current SIP
account status (default status is unconfigured and unregistered), the
registration status and Ethernet MAC address of the InformaCast
instance, and the speaker’s system information (current IP address,
Ethernet MAC address and system time).
8. To change the IP address settings, go to the Network page and modify
settings in the WAN section. To set the network for DHCP, click the
Dynamic IP radio button. For static IP addressing, click the Static IP radio
button and fill in the relevant IP address fields with values from your
network administrator.

Surface Mount Speaker with InformaCast Page 12 v 1.8.1-20190215
9. To change the SIP account settings, go to the Accounts page and modify
settings in the account. Most users will only need to set
Username/Number (the phone number or extension assigned to this
speaker) and Domain (the hostname or IP address of your SIP server).
You may also provide an Account Name, which is used only for logging
purposes, and a Display Name, which may be used by your SIP server
depending on its configuration.
If a password is required for your SIP server or proxy server, provide it
in the Password field. If your SIP server or proxy server requires an
authentication username that is different from the name entered in
Username/Number, enter it under the Advanced tab in the Auth
Username field.
10. After configuring the network and SIP settings for your speaker, use
the configuration settings described in the next sections to customize
the speaker, intercom, panic button and InformaCast functionality.
11. Be sure to set up your speaker(s) and relays (if applicable) in the
InformaCast programming utility. For setup assistance, visit

Room 1 InformaCast
Audio Mixing –Maximum number of InformaCast audio
broadcasts to play simultaneously on this channel. Note 1
To disable audio mixing, choose 1.
Manual config server URL –Enter the URL of the InformaCast
server if needed.
Within a typical installation, the configuration server will be
detected automatically. However, there may be times when
that detection fails and this must be done manually. There
are two methods, HTTP or TFTP.
HTTP –The format of the URL must match
“http://<ip_address>:<port number>/<path_on_server>”.
It is easiest to grab this information from the SPL
configuration found under Admin | Network Parameters
| SLP Parameters on the InformaCast server.
TFTP –If a TFTP server is in use, the format of the URL
must be
“tftp://<ip_address>:<port_number>/<path_on_server>”.
Note 1: While each channel is capable of playing up to three (3) audio
broadcasts at once, the maximum number of simultaneous high-quality
(44.1 kHz) audio broadcasts is two (2) per device.
