18) Chassis Open Alarm Lead (4 pin CHASSIS)

This lead is for a chassis designed for chassis intrusion detection. This requires an external detection mechanism such as a chassis intrusion monitor/ sensor or microswitch. When any chassis component is removed, the sensor is triggered and a high-level signal is sent to this lead to record a chassis intrusion event.The event is then be processed by software such as LDCM. When not using the chassis intrusion lead, place a jumper cap over the pins to close the circuit.
