WIRING
WARNING
Before working on the FAAST XT system, notify all required authorities that
the system will be temporarily out of service. Make sure all power is removed
from the system before opening the unit. All wiring must be in accordance
with local codes.
POWER CABLES
Use the power ratings of the unit to determine the required wire sizes for each
connection. Use the power ratings of the connected products to determine the
wire size.
CONDUIT USAGE
If electrical conduit is used for system wiring, terminate the conduits at the
cable entry ports on the top or bottom of the unit, using the appropriate con-
duit connectors.
1. Run all wiring, both power and alarm, through the conduit and into the
left side of the unit enclosure, as seen in Figure 3.
2. Attach the appropriate wires to the supplied Euro connector. Follow ap-
propriate local codes and electrical standards for all cabling.
3. Plug the appropriate connector into the mating connector on the unit.

SYSTEM WIRING
To maintain compliance with EN54-20, the power supply used with FAAST XT
must be EN54-4 approved. The system requires an EMI line filter in order
to meet CE certification to CISPR22 specifications. The EMI line filter (in-
cluded) needs to be connected between the DC power supply and the FAAST
device. The EMI filter needs to be located within the wiring compartment
of the FAAST XT unit. Refer to Table 1 for the field wiring terminal descrip-
tions of the unit. Refer to Figure 4 for a typical connection for monitoring the
FAAST XT system at a Fire Alarm Control Panel (FACP). Refer to your FACP’s
installation manual for instructions on connecting FAAST XT.
