+# The PIR-EF4 was produced by Nortek (nortekcontrol.com)
+# It was released in 1996 and works with 9 Volts battery.
+# The sensor broadcast its ID when it is triggered.
+# The ID is defined on 2 bytes.
+# There is no CRC or other data transmitted.
+# The modulation is OOK with PPM at the frequency of 315MHz. :
+# Guessing modulation: Pulse Position Modulation with fixed pulse width
+# Attempting demodulation... short_width: 848, long_width: 2132, reset_limit: 8488, sync_width: 0
+# Use a flex decoder with -X 'n=name,m=OOK_PPM,s=848,l=2132,g=2136,r=8488'
