VISTA-100 Installation Instructions

number or group is determined by the setting of DIP switches. Other devices have a built-in

unique serial number which must be programmed into the control as its zone number. To

set up the polling loop, take the following steps:

1. Run wires to each device on the polling loop. No individual wire run may exceed the

lengths given in the following table. In addition, no more than 64mA may be drawn on

any individual wire run. When a star configuration is used, the total length of all wire

runs combined cannot exceed 4000 ft (2000 ft. if using unshielded wire in conduit or

shielded wire). Twisted pair is recommended for all normal wire runs.

Maximum Polling Loop Wire Runs

Wire Gauge Max. Length

#22 gauge 650 feet

#20 gauge 950 feet

#18 gauge 1500 feet

#16 gauge 2400 feet

When running polling loop wires, do not run them within 6 inches of AC power, telephone, or

intercom wiring. Since the polling loop is carrying data between the control panel and the devices,

interference on this loop can cause an interruption of this communication. The polling loop can

also cause outgoing interference on the intercom or phone lines. If this spacing cannot be

achieved, shielded wire must be used. (Note that the maximum total wire length supported is cut

in half when shielded wire is used.)

2. Wire each device to the polling loop, making sure to use correct polarity when making

connections (refer to the device's instructions). If you are using serial number

devices, and you intend to have the control program each serial number

automatically, wire no more than 25 of these devices to the control at a time.

Then power up and program them (as described later in this section) before connecting

the next 25. Leave previously programmed devices connected.

3. If you intend to enter the serial numbers manually through the keypad or through V-

LINK downloading software, all the devices may be connected before powering up to

program them.

4. Note the polling loop devices that have DIP switches on them. Set each device's DIP

switches for the zone number you are assigning to it. Refer to the device's instructions or

the DIP Switch Tables in Appendix B when setting addresses.

Certain polling loop devices, such as the 4193SN and 4191SN, do not have DIP switches.

Instead, they have embedded serial numbers which must be programmed into the control

during #93 Menu Mode Zone Programming.

Certain polling loop devices have a DIP switch that can be used either to select the device's zone

number or to select the programming of a unique, embedded serial number into the control panel.

When used with VISTA-100, these devices

must

be set for the serial number mode of operation.
