Overview
The IDNAC power supply has a single SLC
for connecting addressable IDNAC devices.
The power supply is compatible with
TrueAlertES and TrueAlert Addressable
product lines (both multi and fixed candela).
The IDNAC output is Class B only. Class A
operation requires use of optional module
4007-9804, IDNAC dual Class A isolator.
The output is duplicated on the terminal block
to facilitate “T” tapping on the circuit at the
panel. EOL resistors are not required.
All wiring is supervised and power-limited.

Wiring Wiring Parameters
Table 4-4 identifies the IDNAC wiring parameters that must be considered.
Note: If a shielded wire is used, cut it and tape it.

Isolator
Isolator (DCAI)
To wire an IDNAC as a Class A circuit, the DCAI modules (4007-9804)
is required (2 Class A circuits with fault isolation). For more information
on Dual Class A isolator and on how to calculate Class B wiring with
isolation, refer to the DCAI Installation Instructions 579-1029 .
