Simplex 2001 System Test #4 - System Sensor L Series P2RL on 90BPM March Time 

Never heard a l series on 90bpm march time do a p2r

Super interesting combo

That reminds me of the late Blue CFL putting an Advance chime strobe on whoop on his 2001 system.

The 4-wire or horn only models will perform better doing March time and other codings. They both have a “Coded” feature that the two wire horn strobe models don’t have and they don’t gradually die after every pulse.

This sounds quite interesting and pretty quiet on this code almost like one of those older Simplex 4903 electronic horn strobes

Idk why does this have very long delays

Face reveal!
