Installation instructions

Caution: Electrical supervision requires the wire run to be broken at each terminal. Do not loop the signaling circuit field wires around the terminals.

To install the speaker:

• 1. Remove the cover by depressing the tab on the side of the unit with a small screwdriver. Turn the cover counterclockwise to release.
• 2. Connect the speaker terminals to the signal circuit field wiring. You must observe polarity for the unit to function properly. See Figure 1.
• 3. Slide the wattage switch to the desired wattage tap (2 W, 1 W, 1/2 W, or 1/4 W) by aligning it with the indicator below the switch. See Figure 2.

• 4. Mount the unit onto a compatible electrical box. The switch selector position must be as shown in Figure 3.
• 5. Replace the cover by positioning the alignment arrows together and rotating the cover clockwise.
• 6. Test the unit for proper operation.
