The “Central unit” and “Mains voltage” LEDs have not been mentioned here and in normal mode they light up
green, thus not indicating a fault.
“Service timer” LED flashes in normal mode.

Run the setpoint function if an alarm notification is displayed during a fault test:
quickly covering the prism must lead to a fault at SD-L-F1 during installation of SD-L-F1. SD-L-F1 detects
this using the very low signal level (< 15 %) that is triggered if the retroreflector is covered quickly (within
2 seconds).
In some installations SD-L-F1 indicates a FIRE signal rather than an ERROR signal upon quickly
covering the prism. This is based on the fact that the installation has other “scattering”, reflecting surfaces
in the vicinity of the beam path that are influencing the measurement.
The Setpoint function is a software function within SD-L-F1 with which the system can compensate for
scatter reflections.
Adjusting the Setpoint:
Quickly cover the prism after having installed and equipped the detector. If SD-L-F1 displays a FIRE
signal rather than a FAULT signal, once again remove the cover from the prism. Then simultaneously
press and hold the left and right direction buttons on SD-L-F1. The middle LED above the SD-L-F1
buttons flashes 3x. Then release the buttons. A further fault and fire test is subsequently necessary for
verification.
