Improved Paging Amplifier (Model CPA-7B)

The CPA-7B will provide higher fidelity paging from either analog stations or paging ports and will be modularly expandable to support larger paging applications.
Add Paging, Loud Ringing and Background Music to Centrex, PABX, and Key Systems
The CPA-7B is a cost effective, multi-purpose, telecom paging system.

The CPA-7B provides 6 watts of low noise, high fidelity power for many telecom paging and night bell applications. Multiple units can be cascaded to power more speakers for larger paging applications.

The CPA-7B can be interfaced to ringing Centrex/C.O. lines, analog PABX/KSU stations, unused trunk inputs, as well as standard paging ports.

For loud ringing, the CPA-7B generates an adjustable loud warble from a dry contact closure or a ringing Centrex/C.O. line or analog PABX/KSU station.

The CPA-7B is easy to install and can eliminate the installation of multiple bells, relays and paging cards.
