3.Chassis Alarm (4-1 pin CHASSIS1)

This lead is for a chassis designed with intrusion detection feature. This requires an external detection mechanism such as a chassis intrusion sensor or microswitch. When you remove any chassis component, the sensor triggers and sends a high-level signal to this lead to record a chassis intrusion event.

By default, the pins labeled “Chassis Signal” and “GND” are shorted with a jumper cap. If you wish to use the chassis intrusion detection feature, remove the jumper caps from the pins.
