Paging- How to Install Paging
Generally
there are two types of paging systems either already installed or newly
installed in most premises; low
power 24-volt self amplified (SA) systems and high power 70 volt central
amplified (CA) systems. Each system uses its own design and features, including
specific hardware. A voice paging system is a popular add-on peripheral to a PBX
telephone system and one that is a must have in many businesses, including warehouses,
schools, loading docks, and freight facilities. Although some small office
establishments manage their paging through the desk phones, overhead paging through
speakers is a preferable method. More open types of businesses overhead horns (warehouse and
industrial) are the best solution.

Bogan and Valcom represent the go-to manufacturers for paging amplifiers, horns, speakers and know how. Below you'll find some excellent resources that explain designing, installing and the types of hardware needed for paging systems.
First a tip.
If the phone system has a paging output, it is typically a 2-wire
connection. If there is no paging interface, one will be required, a
Bogan
TamB2 is a great choice. Using a station line connected to the Tam-B, the
user simply dials the extension number. The TAM-B recognizes the 90V ring
signal, accepts the call and then
complete the call to the paging
system. For great prices from a trusted source: Bogan TamB2 with power
supply.
The
Cisco SPA112 has two FXS ports to connect to traditional telephones and
other analog devices, one Ethernet port and a power port.
Note: Some SPA100 devices will come with two Ethernet connections, one the
WAN or Internet, the second for the LAN or as a PC connection.

A
Bogan TamB2 interface adapter will act as a gateway device to your paging or
speaker systems. There can be several setups, each explained in the
TamB2 manual. The connections can vary depending on the voltage
requirements and other factors which the manual describes and gives you
schematics for different devices.
As
shown the connection from the Cisco IAD (SPA112 or PAP2T) connects
directly to the TamB using the Tip and Ring connections where the phone system
is listed. From there, the connections to the paging system
would be handled with more specific information for different paging/speaker
systems. This information with diagrams is spelled out in the
Bogan Tam-B manual.
NOTE: Along with the two types of paging systems, CA and SA, an additional major difference is one-way paging or a talk-back solution.
Designing Paging- 3 Types of Speakers That are Used
-
There are three kinds of speakers. They are:
- Ceiling Speakers which are typically found in dropped ceilings in offices, stores and ceilinged environments.
- Horns for outdoors, warehouse, dock areas, etc. They can range from small to larger capacities and be indoor or outdoor weather proof models.
- Wall Baffles that are used when ceiling height is prohibitive or ceiling speakers are unpractical to install (no clearance room).
Self-Amplified 24 volt systems represent a suitable choice for small installations. For larger installations a 70 volt Central-Amplified system is better and more economical.
Important:
Along with choosing paging devices; horns, ceiling speakers, amplifiers and power supplies, choosing the correct wire type and size is an important aspect to any installation.

Bogan
and Valcom offer a lot of help and guidance when it comes to paging
installations. Start with choosing which system either SA (Self Amplified) or CA
(Central Amplified) and if it will be a talkback system or one-way. Then choose the appropriate equipment. The following
