TEST
Alarm - Cover the detector gradually and make sure that
the air quality is up to 70%. Cover the reflector with a
piece of cardboard. After 10 seconds the detector should
activate a fire alarm and a red LED will be lit.
PRISM INSPECTION TO ENSURE THAT THE BEAM IS
REFLECTED TO THE DETECTOR
Cover the prims entirely and quickly. If the beam is well
aligned, an error message will be displayed after 10
seconds. The yellow fault lamp on the detector head and
on the control unit will be flashing and the word
FAULT
will be displayed.

Screens and menus
This screen is displayed when the beam is aligned.
The air quality is below the alarm threshold.
If the detector is set to latching alarm, you have to reset the
detector's alarm mode by
Alarm Reset
.
Reset can be conducted also by cutting off the power for 5
seconds. If automatic initialization was set, the detector will
initialize to normal mode automatically.
The beam path is completely blocked within 1 second (when
used to check for faults).
