4 Wiring to the FACP
To properly wire the TR-INT50W to the FACP, see Figure 4. The
Internal Amplifier must be powered by a NAC programmed as a
Constant Auxiliary Power. For additional information, refer to
the document in Section 1.1.

4.1 VBUS Wiring
The VBUS is an analog voice bus that broadcasts the recorded
voice messages from the ECS-NVCM to the TR-INT50Ws, or
the voice messages generated from a system microphone to the
TR-INT50W. The maximum resistance on the VBUS is 20
Ω
.
Connect the VBUS from the ECS-NVCM to the VBUS on the ECS-
INT50Ws as shown in Figure 5. VBUS Connection from the ECS-
NVCM to the VBUS on the ECS-INT50W is shown in
Figure 5.
Figure 5 VBUS Wiring for the ECS-NVCM
5 Setting the Device Address
Use the onboard DIP switches to select an ID number assigned to
the TR-INT50W. To determine how to set the DIP switches
assigned to the desired ID number, refer to Figure 6.
.
Figure 6 DIP Switch
After the ID number is set, use programming to add the
TR-INT50W to the System.
6 Speaker Wiring
Each TR-INT50W supplies one circuit for speaker connection.
The speaker circuit can be supervised and wired Class B or Class
A. The speaker circuit provides 50 watts of power at 25 Vrms or
70.7 Vrms. Refer to Table 1.

NOTE: Since the TR-INT50W is powered by a NAC, it will
not be found using the JumpStart Auto-Programming.

Table 1 Wire Lengths
NOTE: The wire lengths in Table 1 are based on a
uniform distribution of the speakers, and that a maximum
of 20% voltage drop on the last speaker is allowed.
*Note: Address 0 cannot be used.
