The following system permits use of both the BGM amplifier for quasi-dual-origination broadcasts and
the standby amplifier.
Prepare a standby amplifier (here, a VP-1120 or VP-1240) with the same output power rating (wattage) as that
of the VM amplifier. Place a relay between the SV-200M's CN3 connector and the VM amplifier's RY PCB 1003
circuit board, and control the relay by means of the Surveillance I/O connector's Pin 12 (Power Amplifier Failure)
and Pin 13 (Setting/Checking Busy). Details are explained in 4-5-9 Operation When Using Both the Standby and the
Quasi-Dual-Origination Amplifiers section.
NOTE: The amplifiers cannot be modified not to distribute external BGM to the specified zones.
