Bendix Commercial Vehicle Systems BACKSPOTTER - Manual (Page 14)

Installation
Backup Alarm Control Feature
(optional harness required)
The Bendix ™ BackSpotter ® sensor has a built-in relay output that can control a
backup alarm, or any low current 12-volt device, whenever an object is detected.
This feature allows the backup alarm to remain silent when the vehicle is in reverse,
unless an object is present in the sensor’s detection zone.
The normally off output is tied to ground when the sensor is off, or no objects are
present. When the sensor is energized and detects an object, the built in relay
switches the output to +12 volts, providing power to the backup alarm via the fused
relay out harness lead.
An optional relay out harness is required to connect the backup alarm to the Bendix ™
BackSpotter ® sensor (P/N 41371-100). The relay out harness is equipped with an
inline 1-amp fuse, which protects the sensor from excess load current.
DO NOT USE A FUSE IN EXCESS OF 1 AMP.
