The GT-4ZP is an 4-Way Video & Power Distribution adaptor that allows one PS-2420UL to power up four GT-1C7W app-enabled tenant stations. The GT-4ZP replaces existing GT-4Z adaptors in a standard GT system, and requires 1 PS-2420UL per GT-4ZP. Each GT-4ZP includes 4 power jumpers (GTW-24J) that are to be installed on the GT-1C7W between the B1/B2 and +/- terminals, which provides power to the GT-1C7W without having to install a local PS-2420UL for each tenant station.
