P/N P01- 04946 Rev C
5.2.1.1.2 NAC Connections
In the NAC application, a reverse polarity of the NAC/Sounder circuit will activate the
HPSA-7100-R to play the audio from the External Audio System; this application
provides an open circuit condition on the NAC/Sounder line in the event of a trouble at the
HPSA-7100-R.
Refer to Figure 5.5 and Figure 5.6 for the NAC connections between the External Audio
Source and the HPSA Audio and Monitoring Bridge (AMB).
1. Run a twisted pair cable, as described above, from the NAC/Sounder output of the
External Audio System to the HPSA-7100-R NAC Input of the AMB.
2. Connect the NAC/Sounder cable to J5-7,NAC (+) and J5-8, NAC (-) on the
AMB. To activate the HPSA-7100-R from the NAC, NAC (+) must be positive
and NAC (-) must be negative when the NAC is active.
5.2.1.1.3 Contact Closure Connections
In the Contact Closure application, the Dry Activation Contact output from the External
Source will be connected to the contact closure (CC) input of the AMB. A closed contact
from the External Source activates the HPSA-7100-R to play audio. Refer to Figure 5.5,
Figure 5.6,
Figure 5.10 and Figure 5.11 when connecting the contact closures to the
AMB.
1. Run the two pairs of copper wire from the external source through the HPSA-
7100-R cabinet to the Audio and Monitoring Bridge as described above.
2. Connect the contact closure output of the External Audio System to J5-5, CC IN
A and J5-6, CC IN B on the AMB. The contact closure input of the AMB is
designed to work only with a dry contact closure output from the External Audio
System; supervision must be provided by the External Audio System.
3. If required by the External Audio System, install the End-of-Line Resistor across
J5-5, CC IN A and J5-6, CC IN B .
The HPSA-7100-R powers on to play audio if the electrical polarity of the
NAC circuit is incorrect or if the Contact Closure from the External
System is closed.
Some audio systems require end of line resistors (EOLR) for supervision.
Install the EOLRs at the AMB according to the manufacturer's instructions.
All wiring to and from the HPSA must be Class 2/Power Limited.
