Important Safety Information
INSTALLATION
An improperly installed 8188 Ceiling Speaker could fall from the ceiling
and cause serious injury or death. The four screw mounting clamps will
adequately support the speaker if the ceiling material is sufficiently
strong. An optional T-bar mounting bracket (Algo 8188-TBR) is
recommended for acoustic ceiling tile and may be required for
compliance with local building code. A ¼-20 threaded insert nut on top
of the speaker housing can accept an eye-bolt (not supplied) for chain
or cable support and additional safety.
Local building codes may require one or more additional safety
measures, particularly in earthquake prone regions.
EMERGENCY COMMUNICATION
If used in an emergency communication application, the 8188 Ceiling
Speaker should be routinely tested. SNMP supervision is recommended
for assurance of proper operation. Contact Algo for other methods of
operational assurance including the use of the integrated microphone
for automated “sound to air” acoustic testing.
DRY INDOOR LOCATION ONLY
The 8188 Ceiling Speaker is intended for indoor dry locations only. For
outdoor locations Algo offers weatherproof speakers and strobe lights.
CAT5 or CAT6 connection wiring to an IEEE 802.3af compliant
network PoE switch must not leave the building perimeter
without adequate lightning protection.
No wiring connected to the 8188 Ceiling Speaker may leave the
building perimeter without adequate lightning protection.

About the Algo SIP 8188 Ceiling Speaker
The 8188 Ceiling Speaker is a SIP compliant and multicast capable IP
speaker suitable for voice paging, notification, and background
music.
The 6.5” (165mm) coaxial speaker is G.722 wideband capable and
music capable using a fullband codec. An integrated microphone
provides talkback capability and ambient noise detection for
automatic level control.
Dual SIP extensions provide both voice paging and notification (ring)
capability. One or both extensions can be registered with any
Communication Server (hosted or enterprise) that supports 3rd party
SIP Endpoints.
Multiple speakers in a SIP environment require only one speaker to
register as a SIP extension. Multicasting capabilities allow the SIP
registered speaker to page and simultaneously stream multicast
audio to the other speakers.
The 8188 Ceiling Speaker is configured using central provisioning
features or by accessing a web interface using browsers such as
Google Chrome, Firefox, or Internet Explorer.

Getting Started - Quick Install & Test
This guide provides important safety information which should be
read thoroughly before permanently installing the speaker.
1. Connect the 8188 SIP Ceiling Speaker to an IEEE 802.3af compliant
PoE network switch. The blue LED will remain on until boot up is
completed –about 30 seconds.
2. After the blue LED turns off, press the reset switch (RST) to hear the
IP address over the speaker. The IP address may also be discovered
by downloading the Algo locator tool to find Algo devices on your
network: www.algosolutions.com/locator
3. Mount the speaker per the instructions in this guide.
4. Access the 8188 Ceiling Speaker web page by entering the IP address
into a browser (Chrome, IE, Firefox etc) and login using the default
password algo.
5. Enter the IP address for the SIP server into the SIP Domain field
under the BASIC SETTINGS > SIP tab.
6. Enter the page SIP extension and password. (Note the speaker
supports two SIP extensions. The page extension auto-answers for
paging. The ring extension plays a WAV file over the speaker without
answering.)
7. Make a call to the speaker by dialling the page SIP extension from a
telephone. The speaker should auto-answer, play the default pre-
announce WAV file, and open a speech path.
8. Carefully install the protective grill working around the grill until fully
installed and flush with the housing.

Ceiling Installation
The 8188 Ceiling Speaker is intended to be mounted in a T-bar acoustic
tile or gypsum ceiling. The speaker may also be suspended using a chain
or cable (see section –Suspended Installation).
An optional T-Bar support bracket (8188-TBR) is available that can
transfer the speaker weight onto the T-bar rails. Installation instructions
are provided with the support bracket.
The speaker is shipped with the metal protective grill removed for
convenience. This provides access to the four Phillips head screws that
operate the four clamps. The clamp screws must be sufficiently loose to
allow clamps to rotate and clear the ceiling material thickness. When
tightened, the clamps are locked to prevent rotating. Removal of the
speaker from the ceiling requires the clamps to be sufficiently loosened
before they can rotate in to pass through the 8” (20.5cm) hole.
The removable trim ring must be snapped into location flush with the front
surface of the speaker. Lay the trim ring on a flat surface with the ribs
facing down and place the speaker in the middle with the speaker facing
up. Align the four tabs with the cavities on the speaker housing and slide
the trim ring up the speaker housing until it snaps into place flush with the
top.
An 8” (20.5 cm) round hole is required in the ceiling. The wiring
connections are easiest made prior to mounting if possible.
Network connection is made by inserting a RJ45 plug into the jack on top
of the housing. Wire connections for relay input and output (if used) are
made using the 4 position pluggable terminal block provided.
The protective wiring cover may be attached after connections are made.
The cover helps prevent any water drips from HVAC or roof leaks from
entering the enclosure, as well as keeping dust out of the connections.
The cover also provides additional strain relief for the wiring.
With connections made, lift the housing into the ceiling and tighten the 4
clamps using a #2 Phillips screwdriver until snug.
Do NOT Over-tighten the clamps. If the clamp screws are over-
tightened after the trim ring is snug, the trim ring may detach from the
housing requiring the speaker to be removed from the ceiling and the trim
ring re-attached.

After installation and testing, gently work the speaker grill into its friction fit
position and ensure it is evenly flush to the housing around the edge. The
speaker grill is intentionally tight to prevent falling from the ceiling.
A tool supplied with the 8188 Ceiling Speaker can be used to remove the
grill. If lost, a small Allen key or heavy duty paperclip bent into an L shape
can be used to remove the grill by pulling close to the edge.
Air Handling Spaces UL2043
The 8188 Ceiling Speaker was tested and found to be compliant with
UL2043 requirements by an independent NRTL registered lab and is
therefore suitable for installation in air handling spaces. A copy of the test
report is available by request.
Suspended Installation
To suspend the 8188 Ceiling Speaker from a ceiling or truss you will need
additional materials not included with the speaker:
¼” -20 Eye-bolt
Thread locking adhesive
Load bearing cable or chain
For suspended installations, the trim ring is not used. The four clamps
may also be removed for aesthetics. The back housing and grill may be
painted if desired but ensure the speaker and wire connectors are properly
masked.

2014-09-12 4500 Beedie St Burnaby BC Canada V5J 5L2 [e-mail]
Page 10 www.algosolutions.com
Apply a thread locking adhesive and install a ¼-20 eyebolt (not included)
into the threaded nut insert on the top of the speaker housing. Screw the
eye-bolt in completely (3/8”) and use a thread locking adhesive to prevent
the bolt from working itself out.
Suspend the speaker using chain or cable rated to support at least 3 x the
weight of the speaker and preferably capable of supporting 200 lb (91 kg)
loads in case the speaker is used for support while on a ladder. Secure the
cable or chain to the speaker and ceiling or truss properly to ensure a safe
installation.
Wiring exits from the protective cover towards the center of the housing
to be run up the cable or chain and dressed neatly using cable ties.
Web Interface
The 8188 Ceiling Speaker is configurable the using web interface or
provisioning features.
After boot up the blue LED will turn off and the speaker will have
obtained an IP address. If there is no DHCP server the 8188 Ceiling
Speaker will default to the static IP address 192.168.1.111.
Press the reset switch (RST next to the LED) momentarily to hear the
IP address over the speaker. The reset switch will not cause a reset
unless pressed during power up.
The IP address may also be discovered by downloading the Algo
locator tool to find Algo devices on your network:
www.algosolutions.com/locator
Enter the IP address (eg 192.168.1.111) into a browser such as
Google Chrome, Firefox, or Internet Explorer (other than IE9). The
web interface should be visible and the default password will be algo
in lower case letters.
SIP Paging One Speaker
The 8188 Ceiling Speaker can be registered as a third party SIP
extension with a hosted or enterprise Communications Server
supporting 3rd party SIP endpoints.
To register the speaker with the SIP server, use the Basic Settings 
SIP tab in the web interface to enter the Communication Server IP

address, extension, username, and password. This information will be
available from the IT Administrator.
If VLAN is used, navigate to the Advanced Network Settings tab to
set VLAN options.
(Note, once the speaker is using VLAN you will need to be on the same
VLAN to access the web interface.)
The speaker may now be accessed by dialling its assigned extension
from a telephone, device, or client. The speaker will auto-answer, play
the default WAV pre-announce tone, and allow voice paging until
disconnected.
There are a number of configurable speaker options:
Increase or Decrease Speaker Volume
Enable AGC (automatic gain control)
Enable Ambient Noise Monitoring (speaker volume adapts to
background noise)
Enable Talkback
Customize pre-announce tone WAV file
The best voice paging quality and intelligibility will be obtained using
the G.722 wideband audio codec. Most current IP telephones support
G.722 which is sometimes referred to as “HD” voice or audio.
SIP Paging Multiple Speakers (Using
Multicast)
Multicast features in the 8188 SIP Ceiling Speaker require that only
ONE of the speakers be registered as a SIP extension. Additional
speakers may be added as multicast slaves receiving a stream from
the SIP registered speaker.
The SIP registered speaker will page normally while simultaneously
streaming audio to the slave speakers. The slave speakers do not
require SIP extensions and do not need to register with the SIP
Communication Server.
To enable multicast streaming from the SIP speaker, go to its web
interface and navigate to the Basic Settings Multicast tab.
Choose multicast mode “Master/Sender” and zone “All Call”. The

Document 90-00067 A Algo Communication Products Ltd [phone]
2014-09-12 4500 Beedie St Burnaby BC Canada V5J 5L2 [e-mail]
Page 12 www.algosolutions.com
multicast addresses pre-populated in the table will work in most
cases.
To enable multicast monitoring in the other speakers, go to the web
interface for each speaker and again navigate to the Basic Settings
Multicast tab. This time though, choose multicast mode
“Slave/Receiver”. There is no need to select a zone as the speaker
will automatically monitor the “All Call”zone IP address.
The page pre-announce tone is generated from the SIP/Master. The
following options are valid for each multicast slave speaker:
Increase or Decrease Speaker Volume
Enable Ambient Noise Monitoring (speaker volume adapts to
background noise)
Talkback can only be used for the SIP/master speaker. When paging
with talkback enabled, only the area near the SIP/master speaker is
covered for talkback. The microphones in the multicast/slave
speakers are disabled except for ambient noise monitoring.
SIP Paging Multiple Speakers (Using
Individual SIP extensions)
In some cases it may be desirable for every speaker to have a SIP
extension. Multicast may still be used to page multiple speakers but
each speaker can also be called individually or generate a call when
appropriately configured.
A speaker configured as a SIP Multicast Slave will give its highest
priority to a page using its SIP extension.
Communication Servers with the capability of dialling many SIP
extensions simultaneously for paging may be able to create zones by
call hunt groups and also page telephone speakers in conjunction
with overhead speakers.
Multicast Page Zones
The 8188 SIP Ceiling Speaker currently supports nine separate
multicast “zones” defined by the multicast IP addresses.
Somewhat arbitrarily, these zones are defined as below but may be
used in other ways. The important consideration is that there is a

Document 90-00067 A Algo Communication Products Ltd [phone]
2014-09-12 4500 Beedie St Burnaby BC Canada V5J 5L2 [e-mail]
Page 13 www.algosolutions.com
priority hierarchy –streaming activity on a zone higher on the list will
be treated as a higher priority than a zone lower on the list –with
music being the lowest priority.
Priority
All Call
Zone 1
Zone 2
Zone 3
Zone 4
Zone 5
Zone 6
Music
In the scenario involving only one speaker registered as a SIP
extension, the multicast page zone can be selected by keypad input.
Alternatively, several speakers can be registered with SIP extensions
and each SIP speaker set to multicast on a different multicast zone.
No keypad zone selection in that case is necessary –the zones are
defined by the SIP extension called.
PolycomTM Group Paging
The 8188 Ceiling Speaker has been designed to support Polycom
Group Paging.
The 8188 Ceiling Speaker can be added to a Polycom page group so
that voice paging is heard over Polycom telephone speakers and
overhead paging simultaneously.
Polycom Group Paging can be configured on the Basic Settings 
Multicast tab.
The 8188 Ceiling Speaker may be accessed remotely via SIP and
generate a multicast page within the LAN sending voice page to both
Algo paging speakers and Polycom telephones. Audio delay may be
added to the 8188 Ceiling Speaker to synchronize with voice page
over the Polycom telephone speakers.

Page 14 www.algosolutions.com
SIP Activated Notification
In addition to voice paging, the 8188 Ceiling Speaker can play audio
files for emergency, safety, or security announcements.
Audio WAV files can be stored in speaker memory and played over
the speaker in response to an event such as ring or message waiting,
and also multicast to other speakers on the network.
SIP Ring Event
Set Monitoring Mode to "Monitor Ring". When a call is made to the
SIP extension the 8188 Ceiling Speaker will play the selected WAV
file from memory. Often, the 8188 Ceiling Speaker will be part of a
hunt group or ring group to ring in conjunction with a telephone.

Wiring Connections
Network Connection
The speaker provides a RJ45 jack for network connection. A cable run
from the switch can be terminated to a modular jack with connection
by patch cord, or terminated with a RJ45 plug.
PoE (Power over Ethernet) must be 48V 350 mA IEEE 802.3af
compliant whether provided by the network switch or injector.
Terminal Block Relay In
By default, these terminals are inactive. Connection options are a
normally closed switch, normally open switch, Algo 1202 Call Button
with large blue button, Algo 1203 single gang backlit wall switch, or
EOL resistor termination.
Terminal Block Relay Out
By default these terminals provide a contact closure when the 8188
Ceiling Speaker is active.
Blue LED Indicator
The blue LED is visible through the speaker grill and by default will be
on when the speaker is active. The blue LED will also be on during
power up and boot process.
The blue LED can also provide a heartbeat with a flash every 60
seconds to indicate that the speaker is powered and connected to the
network.
If the 8188 Ceiling Speaker is in talkback mode the blue LED will be
flashing.
Reset Button
A recessed reset button (RST) next to the blue LED can only be
used to reset the 8188 Ceiling Speaker at time of power up. To
reset, reboot or power cycle the 8188 Ceiling Speaker. Wait until
