 Product Overview 
Formed as the `SL’-series, Siemens is now offering horns, strobes, and horn-strobes 
with LED based strobes to its notification-appliances portfolio. 
With the `SL’-series, Siemens now offers  an additional range of products with low 
and  high  candela  settings  that  makes  these  sophisticated  notification  appliances 
ideal for new installs and retrofit applications. 
Innovative light-emitting diode (LED) strobe technology provides an energy-efficient 
means for a significantly reduced current draw. 
The strobe portion of these appliances meets the 20 millisecond light-pulse-duration 
requirements of the 2016 edition of NFPA 72. This feature allows existing Xenon and 
the new LED devices to be used in the same field-of-view. 
In  a  single  device,  the  `SL’-series  can  provide  alarm-signaling  tones  for  dual 
applications. All strobe models in the series feature multi-candela settings (15 | 30 | 
75 | 95cd) on a single appliance. 
Additionally, there are two (2) modes of operation for the audible portion of these 
notification appliances: 
•   T3 (coded) 
•   Continuous 
The  `SL’-series  of  horns,  strobes  and horn-strobes  devices are  produced  in a  sleek, 
modern design. Its structure and design provide high-quality energy efficiency in an 
aesthetically pleasing, low-profile design that is consistent to the look of the interior 
composition of the building application. 
This `SL’-series is exclusive to indoor ceiling-mount applications.  The Model `SLHC’-
series horn appliances work in either 12V or 24VDC, whereas the  Series `SLSC’ and 
`SLHSC’ strobe and horn-strobe devices are specifically for 24V operation.
