FIGURE A.9 Multi-Use SP40S with Multiple HPSAs (Class B Wiring Shown)
NOTES for Figure A.9, Multi-Use SP40S with Multiple HPSAs:
1.
The Multi-Use application requires an SP4Z-A/B Speaker Audio Splitter, shown with four
independent Class B audio zones (refer to the SP40S Manual for Class A wiring). One zone
(the Audio circuit) must be dedicated for HPSA connectivity, the remaining zones can be used
for in building applications or additional HPSAs wired directly from the SP40S. Refer to the
SP40S Installation, Testing, Operations and Maintenance Manual, P84714 , for details.
2.
The PTT/Trouble contacts utilize the NAC circuit on the SP40S. To activate the strobe NAC
circuit when activation of the HPSA is required, connect the SP40S TB-12 STB OUT (+) and
TB-12 STB OUT (-) to J5 pin 7 NAC IN (+) and J5 pin 8 NAC IN (-) on the HPSA AMB. No
other NAC devices shall be used on the NAC control and monitor circuit.
3.
All trouble contacts on the HPSA’s AMB must be configured for NORMALLY CLOSED (NC);
the NC contacts will open upon loss of power, providing a trouble state.
4.
End-of-Line resistors (EOLR), (not shown in the Audio In line on the diagram), shall be
connected at the furthest HPSA. Verify the SP40S and HPSA are configured for the same
output voltage settings prior to energizing the system; failure to configure the same setting
could damage the HPSA.
5.
Multiple HPSAs can be controlled from a single SP40S. EOLR, are not shown in the figure,
however, an EOLR must be connected on the Audio In and Trouble Contacts on the furthest
HPSA. When connecting to the HPSAs, break the wire runs at each terminal block on the
HPSA, DO NOT loop the wire under the terminals.
6.
Dedicated circuits are required on all audio, control and monitoring lines. Additional circuits
from the SP4Z-A/B are available for in building (or other) applications.
