Be careful not to allow the leads from the transformer touch each other while the unit is plugged in! Shorting out the transformer can easily blow its internal fuse, turning it into a paperweight.

While making connections, either leave the transformer unplugged, or keep the wires separated. This can be used for sirens, bells, strobes, or other devices up to the rated output. These terminals supply volt power to operate keypads, zone expanders, motion detectors, and other devices. Terminal 5 is positive, terminal 4 is negative. The maximum current available for all keypads and detection devices is mA. If you need more than this, you can add a supplemental power supply.

Preferably, this extra power supply would have its own battery backup, so it will continue to work during a power outage. If this isn't possible, make sure at least one keypad is connected to the Vista 20P's own power terminals. To fix this issue, connect a single short pigtail of gauge wire to each terminal, preferably using red for positive and black for negative.

Then, connect the necessary wiring to the appropriate pigtails using wire nuts. Connect data leads from keypads, zone expanders, or other data devices. Include at least one Ademco keypad to make advanced programming easier. And of course feel free to call us any time with additional questions.
