How to Install the 302GCX-024-B SelecTone Amplified Speaker
Installation guide for mounting and wiring the 302GCX-024-B SelecTone amplified speaker device.
Estimated time: 45m
Tools needed:
Screwdriver, Wire strippers, Drill, Wrench (for conduit fittings if applicable)
Supplies needed:
Mounting screws (#10 x 1" wood screws or #10 screws with lockwashers and nuts for metal surfaces), Conduit plug (if needed), Wire connectors, Tone module (purchased separately), Speaker connector card (purchased separately, if applicable)
- Unpack and Inspect
Carefully unpack the SelecTone amplified speaker and inspect it for any damage that may have occurred during transit. File a claim with the carrier if damage is found.
- Prepare for Mounting
Remove and retain the two screws securing the cover to the housing. Remove the cover. For hazardous location models (300GCX and 302GCX series), do not use the 0.9" knockout for concealed conduit mounting.
- Mount the Speaker
Select a mounting location on a flat surface. Place the rear of the housing against the mounting surface. Use the mounting holes as a template to mark drill positions. Secure the unit using appropriate screws for wood or metal surfaces. Ensure the unit is mounted horizontally or slightly downward to prevent water accumulation. For conduit mounting (300GC and 302GC models only), remove the 0.9" knockout, install conduit connection, and then proceed with mounting.
- Make Electrical Connections
Route wires through the 1/2" threaded openings into the SelecTone unit in accordance with National and Local Electrical Codes. Use 12 to 18 AWG wire for power connections, stripping no more than 0.25 inch of insulation. Connect power wires to the appropriate terminals (L for line, N for common, + and - for 24VDC). Connect the earth ground wire to the green screw if required. Plug the connector into the receptacle on the printed circuit board.
- Install Tone or Speaker Connector Card
If using a tone module, plug it into the designated socket. If using a speaker connector card, route the audio signal leads into the enclosure and connect them to the card's audio inputs. Plug the connector card into its socket.
- Reinstall Cover and Test
Ensure the rubber cover gasket is properly seated in the housing groove. Reinstall the housing cover and tighten the securing screws. Energize the unit and test its operation. If the sound level is too high, adjust the internal volume control by removing the cover and gently turning the control with a slotted screwdriver.
