1. DESCRIPTION

The SCA-5070INT is a small form single channel 50W amplifier that can be mounted in the IPA-4000V, AFC-1000V, LOC-
1000 and PSN-1000E. Each amplifier is mounted to an exclusive stacker bracket for secure and accessible mounting. The
SCA-5070INT provides 4 Class B or 4 Class A speaker circuits. The IPA-4000V supports up to thirty-one (31) amplifiers
and the AFC-1000V supports up to 10 amplifiers. The SCA-5070INT communicates via the P-Link communication bus and
audio is distributed through the V-Link 1 audio riser. The amplifier is powered by a constant 24VDC provided by a panel or
PSN-1000 NAC circuit. The SCA-5070INT can support either 25V or 70V speaker circuits. The speaker circuit voltage is
set using the panel programming software. All circuits are power-limited and supervised.

2. SETTING THE ADDRESS

Each P-Link device has a five (5) position dip switch which is used to program the device address ranging from one (1) to
thirty-one (31). The table below may be used to set dip switches when addressing any P-Link module:
