Troubleshooting

The Multisensor Plus signals malfunctions with the yellow
fault LED and with sound signals. If malfunctions occur in
the Multisensor Plus or if the battery voltage is too low, for
safety reasons, doors to rooms with functioning smoke de-
tectors should remain open until the functional impairment
is resolved.
Causes of malfunctions include:
Ì Painting over, taping, or covering the Multisensor Plus.
Ì Demounting for longer than 21 days.
Ì Objects within the area checked by distance control.
Ì Device defect.
Note: Simple causes (see the first three items) can usu-
ally be resolved by the user.

tion „Demounting & Remounting during Renovation".
