In addition to the previous trouble condition restorals, the following specific restorals will occur:
AC restoral
• Turn on the AC PWR LED on the main circuit board
• Reenergize the AC Loss Relay on the main circuit board returning contacts to normal position

NAC (Speaker) Output restoral
• The wiring to each amplifier is supervised for opens and shorts at all times in standby and
while in alarm or when background music
* is enabled. A restoral of a wiring fault will cause
the circuit Trouble LED located on each amplifier module to turn off. It should be noted that
the green AMP SUPV LED is on
• The ACC-ZSM wiring to each speaker circuit is supervised for opens and shorts in standby and
for shorts while in alarm. Restoral of a wiring fault will cause the zone/circuit Trouble LED on
the ACC-ZPMK corresponding to the affected circuit to turn off.
* Note that the Local Authority Having Jurisdiction must approve the use of background music.

communication on the ACS (EIA-485) link will cause the FACP Trouble LED to turn off on
the ACC-ZPMK module.
• The ribbon cable between the ACC-ZPMK and audio panel is supervised. Restoral of
communication will cause the ACC Trouble LED to turn off on the ACC-ZPMK module.
