ZX3 Module Connections
ZX3 Module Paging Output Connections
There are three zone paging outputs on the ZX3 module. The paging outputs are intended to connect to self-amplified speakers, but are also compatible with amplifier inputs as well. The Tip (T) and Ring (R) connections are transformer-isolated audio outputs for driving up to 150 self-amplified speaker inputs.
ZX3 AUX Contacts
Each zone on the ZX3 module has a C-form contact rated at 1A @ 30V DC and 0.5A @ 125V AC. They change state when the corresponding zone becomes active.The ZX3 AUX contacts are not programmable.
ZX3 Power Supply Output
A 24V DC, 1A regulated power supply, built into the UTI312, can be used to supply power to self-amplified speakers through a 2-pin plug-in connector on the ZX3 module. The + and - terminals provide 24V DC for powering the self-amplified speakers. The UTI312 can supply a total of 1A @ 24V DC through all of these connectors.
