Guidelines for Wiring a System

The installer must keep certain guidelines in mind while installing a system. The Vista-128FBPT/250FBPT
•
contains an ECP bus and a polling loop bus for connecting Fire and Burglary devices. When installing both
Commercial Fire and Burglary devices, all Fire devices must be isolated from the Burglary devices on each
bus. This is accomplished by using an ECP isolator on the ECP bus, and a V-Plex VSI on the V-Plex loop,
as shown in Figure 1-1.
Additionally, in Commercial Fire installations, the primary keypad must be connected to Keypad Port 2
•
mounted within 20 feet of the control panel, and wired in conduit.
Synchronization is required on devices connected to an individual alarm output. Each NAC can have its
•
own synchronization module in order to synchronize devices on that output, and those devices should be
located in the same visual/audible area. No synchronization is required between two outputs/individual
sync modules.
Notification Appliance Circuits (NAC) must be wired and isolated or Riser Conductors must be installed in
•
accordance with the survivability from attack by fire requirements in the National Fire Alarm Code, NFPA
