AUTO_SECURITY_SYSTEM_RECEIVER

This receiver is a superheterodyne type tuned to 49 MHz. U2 is a mixer, followed by a 10.7-MHz filter and two-stage IF (U3, U4) and detector. The encoded received RE pulse signal from the an-tenna produces detected pulse from the MC1330P. These pulses are arrtplified by U5 and fed to de-coder IC U6, and MC1450278. Two channels are available at the output, which drives K1 and K2.
