Alarm Module: Specifications
Test Readings, BCM
The following information contain values and instructions for measuring signals and levels on BCM.
Note the test conditions and use common sense when assessing the test results.
First check that the control module has a power supply and is grounded.
Then check all sensor inputs and signals from other systems.
Finally, check the control module outputs. Remember that the test reading does not indicate whether the actuator works.
If any reading is not OK, consult the wiring diagram to trace which leads, connectors or components should be checked more thoroughly.
The specified values refer to a calibrated Fluke 88/97.
Test readings % (+) and ms (+) show the signal's pulse ratio and pulse length, respectively. A test instrument that can measure pulse ratio and
pulse width must be used. The sign indicates the positive trigger pulse, TRIG+. 2
