The SL-2 is a 360° LED Strobe and/or Beacon visual 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 different 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 intensity beacon to remain on and a high intensity strobe to be activated by a contact closure. 6 different 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 polycarbonate lens. Optional Red, Amber, Green and Clear lenses are sold separately, click on Spare Parts for more information. Unit surface mounts to wall, post, panel, 4" electrical box or wet location electrical box round lamp holder cover.
For outdoor installations where the unit is exposed to precipitation or condensation, use model SL-2-EWP. For more information on Enhanced Weather Protection (EWP), see DOD 859.
