Spectralert selectable candela wall-
mounted strobes and horn/strobes offer
key performance features long associated
with the Spectralert name. The selectable
candela strobes and horn/strobes offer av-
erage current draws that are not only lower
than conventional fixed-candela Spectralert
products, but also lower than similar prod-
ucts by others. By consuming less cur-
rent, the ability to connect even more de-
vices per circuit is possible, resulting in
lower installed cost.

notification appliance circuit. A separate
horn control input is available to allow
silenceable audible devices and non-
silenceable visual devices on the same pair
or wires.
Spectralert selectable candela strobes
and horn/strobes offer the same installa-
tion-friendly features synonymous with the
Spectralert name, such as the option of
2- and 4-wire operation; the ability to use
standard size backboxes with no encroach-
ment into the box; and universal mounting
incorporating the labor-saving QuickClick™
feature. Such labor-saving features make
wire connections simple and fast, further
reducing installed cost.
These strobes and horn/strobes offer the
broadest range of candela options. In ad-
dition, they can operate on either 12V or
24V with no settings required. The device
recognizes and self-adjusts to the correct
current automatically. Temporal Pattern 3
or continuous tone options continue to be
available, in either an electro-mechanical
or 3 kHz pattern
