Connecting an Overhead Paging System (OHP)
A Single Zone or Multi-Zone system can be integrated into an existing Synapse network. The control unit or analog amplifier for
the Overhead Paging system connects directly to the ATA via an FXS or the AUX OUT jack, depending on the type of paging
system. Synapse supports most OHP systems that support PBX station ports or auxiliary audio-out connections to a PBX. Some
settings for the OHP may have to be changed to work with Synapse.
If you don't know whether your OHP is Single Zone or Multi Zone, see “Overhead Paging Overview” on page 22. There are so
many types of paging equipment that you may need to contract with a communications equipment professional to install the OHP.
Figure 41. ATA Overhead Paging System Installation
Whether you are replacing a phone system and using an existing (already working) OHP, or installing a new OHP, the
paging system may have settings that need to be adjusted to work with Synapse.
OHPs that are “Line Mode” that cannot be set to “Station Mode” cannot be used with Synapse.
If you want to connect a single-zone paging system to the AUX OUT jack, you may need to buy or make a custom cable.
