The XPC-8 Module (Style Z)
36
XP Series Transponder PN 15888:G 6/11/98
Notification appliance power (and audio power in Voice Alarm applications) is fed to
XPC-8 circuits in pairs of two or more if the NACs are configured for Style Y, or power
is fed to each circuit if configured “Style Z”. The following examples in Figure 30
illustrate some of the typical power feed configurations.
The Full-Share Configuration
Notification appliance, audio, or telephone audio power fed into Plug P3 and jumpered
throughout the XPC-8 module will be shared by all the circuits on the module.
The Half-Share Configuration
Notification appliance or audio power fed into the XPC-8 module from two different
sources can be used to increase the power to individual circuits.
The Quarter-Share Configuration
To provide a maximum amount of power to circuit pairs on the XPC-8, four separate
power supplies can be used. Power from each supply is fed to Plug P3, P5, P7, and P9.
