Figure 3. SHorTing Spring:
NOTE: A shorting spring is provided between terminals 2 and 3 of the mount-
ing plate to enable wiring checks after the system has been wired, but prior
to installation of the final product. This spring will automatically disengage
when the product is installed, to enable supervision of the final system.
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. For K series
products used outdoors at low temperatures, listed candela ratings must be re-
duced in accordance with Table 2. Use Table 1 to determine the current draw
for each candela setting. WIRING DIAGRAMS
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 in Table 1 with the current draw for the specific horn selec-
tion in 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.
