Installing V-Plex Devices

The polling loop provides both power and data to the V-Plex devices, and is constantly monitoring the status of all zones
enabled on the loop. The maximum current draw of all devices on the polling loop cannot total more than 128mA (unless
the system uses a 4297 Polling Loop Extender Module).
Devices that can be programmed via either DIP switches or the built-in unique serial number must be set for the
serial number mode operation.
All devices on the polling loop must be wired in parallel to the [+] and [-] polling loop terminals of the control panel (24
and 25). You can wire from device to device, or have multiple branches connected directly to the control panel in a star
configuration.
