The integrated receiver of the LC372SR is a 30W amplifier with a 25V speaker line. It features two (2) RJ45 connectors for use with LC11CS or LC12DCS wall plate call switches and LC372M remote intercom microphone. These standard call switches provide four logic input functions as normal call, emergency call, lockdown acknowledge, and contractor defined (i.e.
INSTALLATION INSTRUCTIONS LC372 SOUND REINFORCEMENT MODULE The LC372SR is powered via Ethernet cable from a LANcom power injector located near the device or in a remote tele- communications closet along with other data switch and distribution equipment. An internal fan and cabinet vents help keep the internal circuitry cool during operation.
