Signaling Speakers. The speakers are suitable for outdoor use with a
UL1480 wet locations rated enclosure.
The speakers include a supervisory capacitor and are suitable for
installation in systems employing supervised circuitry (25V/70.7V).
Maximum supervised circuit voltage is 24VDC.
Speaker direction and the output level are easily adjustable. Output
wattage is easily adjusted by an internal rotary switch.

3. Wire as follows referring to Figure 3:
a. Connect audio in (+) and audio in (-) to the "AUDIO INPUT/
OUTPUT CONNECTIONS", 2-place terminal on faceplate.
Observe polarity on faceplate label. Shielded cable
recommended.
b. When connecting multiple speakers or supervised circuits;
Connect wires leading to next signal or end-of-line resistor
on the same INPUT/OUTPUT terminals (+) and (-) on the 2-
place terminal as shown in Figure 4. Again, polarity must be
observed.
4. Adjust voltage/wattage level by turning rotary switch located
on internal faceplate (Figures 3 & 4). See Table 1 for Power Tap
Selection Settings.
5. Tightly secure the signal box cover using (4) retained cover
screws.
6. Torque signal box cover screws to a minimum of 20 in-lbs.
WARNING
To ensure integrity of the enclosure: Ensure the cover gasket,
part number P-007549-0069, is adhered into groove at cover
perimeter before replacing the signal box cover.
Ensure that the (4) collar gaskets, part number P-041930-0362,
are in place on each cover screw before securing the signal
box cover.
When securing cover, start screws by hand, making sure
they are threaded into tapped holes in housing bosses before
securing with a screwdriver. Torque signal box cover screws to
a minimum of 20 in-lbs. This ensures the required tight fit.
To prevent fire and shock, wire the Adaptatone only as described
in this installation instruction.
