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 use a page all through the desk phones, overhead paging through speakers is a preferable method. For more open types of businesses overhead horns (warehouse and industrial) are the best solution.
Bogan and Valcom are the go-to manufacturers for paging amplifiers, horns, speakers and know how. Below you'll find some excellent resources that explains designing, installing and the types of hardware needed for paging systems.
First a tip.
If the phone system has a paging output it would typically be 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
completes the call to the paging system. For great prices from a trusted source: Bogan TamB2 with power supply.
Self-Amplified 24 volt systems are generally a good choice for small installations. For larger installations a 70 volt Central-Amplified system is better and more economical.
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 either a talkback system or one-way. Then choose the appropriate equipment. The following how-to guides offer everything you'll need:
