Cabling the XMU+ Control Card
To wire the alarm connector
When the system is powered up and running normally, there is a closed circuit
between the Common (C) and the Normally Closed (NC) contacts, and an open circuit
between the Common (C) and the Normally Open (NO) contacts. In an alarm
condition, the opposite occurs, with an open circuit between the (C) and the (NC)
contacts, and a closed circuit between the (C) and the (NO) contacts.
1. Wire the connector pinouts on the alarm connector using the following table.
2. Connect the wires to the appropriate external device, such as a light or a buzzer.
3. Plug the alarm mating connector into the ALARM port on the XMU+ control
card.
