CANDELA SELECTION
Adjust the slide switch on the rear of the product to the desired candela set-
ting in the small window on the front of the unit. All products meet the light
output profiles specified in the appropriate UL Standards. See Figures 1-3.
Use Table 1 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 2.
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. For 4-Wire products,
total current draw may be determined by adding current draw for the specific
candela selection and the current draw for the specific horn selection use
Table 1 and Table 3.

HORN SELECTION
Turn the rotary switch on the back of the product to the desired setting. For
horn and 4-wire horn/strobe products, the current draw for each setting is
listed in Table 3. For 2-wire horn/strobe products (P2 series), current draws
are listed in Tables 4 and 5. The sound output measurement for each horn
setting is shown in Table 6.

NOTE: In positions 7, 8, and 9, temporal coding must be provided by the NAC.
If the NAC voltage is held constant, the horn output will remain constantly on.
Positions 7, 8, and 9 are not available on 2-wire horn/strobe products.
