Battery Backed Sounder

Operation of the battery backed sounder is controlled by the CJB on the LIN bus. The sounder is also connected with a permanent battery supply via the CJB. An integral, rechargeable battery powers the sounder if the battery power supply from the CJB is interrupted.

Dependent on vehicle, a incitation sensor is incorporated into the battery backed sounder, to monitor vehicle attitude, see Inclination Sensor.
