CAUTION
Signal levels exceeding 130% rated signal voltage can damage the speaker.
Consequently, an incorrect tap connection may cause speaker damage. This
means that if a 25V tap is selected when a 70.7V amplifier is being used,
speaker damage may result. Therefore, be sure to select the proper taps for the
amplifier voltage/input power level combination being used.

CandeLa seLeCTion
Adjust the slide switch on the rear of the product to position the desired can-
dela setting in the small window on the front of the unit. All products meet
the light output profiles specified in the appropriate UL Standards. Use Table 2
to determine the current draw for each candela setting. For K series products
used outdoors at low temperatures, listed candela ratings must be reduced in
accordance with Table 3.
NOTE: SpectrAlert products set at 15 and 15/75 candela automatically work
on either 12V or 24V power supplies. The products are not listed for 12V op-
erating voltages when set to any other candela settings.

eLeCTriCaL Wiring
1. Connect the speaker as shown in Figure 1.
NOTE: Do not loop electrical wiring under terminal screws. Wires con-
necting the device to the control panel must be broken at the device
terminal connection in order to maintain electrical supervision.
2. There are two rotary switches on the back of the product The first switch
is used to select either 25 or 70.7 volts input for the speaker portion. The
second switch is used to select the input power of

See diagram.
shorTing spring
NOTE: Shorting springs are provided between terminals 2 and 3 and between
terminals 5 and 6 of the mounting plate to enable wiring checks after the
system has been wired, but prior to installation of the final product. These
springs will automatically disengage when the product is installed, to enable
supervision of the final system.
