LED Strobe and/or Beacon Visual Indicator with
Programmable Brightness and Flash Patterns
The SL-2 is a 360° LED Strobe and/or Beacon vi-
sual indicator. LED's not only are more efficient
and last longer than standard flash tubes but are
also immune to shock and vibration. The LED's are
internally positioned to allow a 360° viewing angle
when the unit is mounted vertically and a 120°
viewing angle when side mounted.
The SL-2 can be user programmed to output 4 dif-
ferent flash patterns: Single Flash, Double Flash,
Quad Flash or Flicker Flash. The unit can also be
programmed as a continuous-On Beacon only,
Strobe only or Beacon/Strobe allowing a lower in-
tensity beacon to remain on and a high intensity
strobe to be activated by a contact closure. 6 dif-
ferent brightness levels are also programmable for
the Beacon and the Strobe. All programming is
stored in non-volatile memory so you won't lose
the programming when the unit is powered down,
allowing you to program units prior to installation.
The SL-2 is designed for indoor applications and
comes standard with a Blue shatter resistant poly-
carbonate lens. Optional Red, Amber and Clear
lenses are sold separately (go to www.vikingelec-
tronics.com and click on spare parts). Unit surface
