PM9-EOL Engineering Datasheet
PM9-EOL Engineering Datasheet
An end-of-line supervision device for PROMATRIX 9000, watching for shorted and open lines.
Verify the loudspeaker line all the way to the end. The PM9-EOL sits at the far end of a line and detects a 25.5 kHz pilot tone to catch shorted or interrupted wiring, with faults reported back through the amplifier. It handles cable runs up to 1,000 m and survives -20 to +50 degrees C. Ordered in boxes of eight with thermal-fuse connection wires. For voice-alarm chains, it closes the loop on line integrity, end to end.
Key features
Watch to the end
detects short and interrupted loudspeaker lines.
Pilot-tone sensing
25.5 kHz tone confirms line continuity at the far end.
Long runs covered
supervises cable lengths up to 1,000 m.
Fault reported
line status is sent back through the amplifier.
Install by the box
supplied in multiples of eight with thermal-fuse wiring.
Barely loads the line
adds less than 100 mW load to the amplifier while supervising the line.
