INTRODUCTION
The Model LED-3/4 Remote Annunciator from
Siemens Builidng Technologies, Inc., shown in
Figure 1 is an eight zone annunciator containing
sixteen LEDs. The LEDs can be used to indicate
the alarm, supervisory, or trouble status of
initiating zones.
A maximum of 2 Remote Annunciators can be
added to each SXL-EX system so that the status
of 8 zones can be displayed at two different
locations.
In addition, a green polling LED on the back of
the annunciator indicates the status of the
annunciator when troubleshooting the installation.
