4. INSTALLING THE SAFETY WIRE (prepared separately by the installer)
Step 1. Tie one end of the safety wire around the terminal fitting
metal.
Note: When using a bare safety wire, wrap insulation
tape around it to prevent electrical contact with
the connection terminals, transformer taps, or
other electric parts.
Step 2. Make a cut in the rubber grommet with a knife or a
screwdriver, then run the safety wire through it.
Step 3. Tie snap ring around a secure channel bar or
suspension bracket.
Step 4. Feed the speaker cable through the rubber grommet
into the dome interior.
Step 5. Secure the fire dome assembly in the ceiling, then
connect the speaker cable to the terminal block.
Step 6. Attach the speaker to the fire dome.
Note: If the speaker cable and safety wire are too long,
to prevent them from being tangled inside the fire
dome, gently push them back out of the fire dome
so the rubber grommet does not get removed.
