Refer to Appendix C, "Driver/Speaker, Audio Input and Control Wire Gauge Distances"
for additional information with respect to identifying proper control wire gauges
distances.
5.2.1 Connect an External Audio System to the AMB
The HPSA-7100-R requires a minimum of two pairs of wires to be run from the External
Source. One pair connects from the audio output of the External Source to the HPSA’s
audio input, the other pair is used to activate the HPSA and connects to either the External
Source’s closed contact output or to the Notification Appliance Circuit’s (NAC) or
Sounder circuit’s output. Additionally, up to six pairs of cable should be connected to
monitor the Trouble state of the HPSA.
The HPSA-7100-R’s Audio Monitoring Bridge provides a User configurable 1 V
RMS
and
25 V
RMS
Audio Inputs. The optional HPSA-7100-V-KIT expands the configurations to
include 70.7 V
RMS
and 100 V
RMS
Audio Inputs.
70 V
RMS
and 100 V
RMS
Audio Inputs require optional module
HPSA-7100-V-KIT.
Designers and installers should consult with the external audio system
manufacturer and manufacturers of transient voltage surge suppressors for
proper selection and installation of primary protectors.
Field Wiring Considerations:
• Audio Input: The HPSA-7100-R presents a load of 1/8 W maximum.
• NAC Input: The maximum voltage is 40 V. The minimum activation
voltage is 9 V. The maximum current is 17 mA.
• CC Input: Utilize dry CC output only. The activation resistance is 1 K
ohms or less; non-supervised - supervision to be provided by the
External System.
Figures in this section show a single Audio, NAC, Dry Contact and Trouble
connections for a single HPSA; refer to Figure A.5 in Appendix A for a
detailed wiring diagrams of connections using multiple HPSAs.
AC Power, Data and Audio cables should be placed in separate
conduits, to minimize the risk of interference.
