When connecting an alarm light to the 02 terminals, the alarm would be powered how?

Explanation:
The alarm terminals are signaling contacts, not a power source. The 02 terminals provide a closed/open path that indicates an alarm, but they don’t supply current to drive a lamp. To light an alarm light, you feed the lamp from an external power source and use the 02 contact to complete the circuit when the alarm occurs. In other words, the lamp is powered externally, and the drive merely switches the external circuit to show the alarm.
