Which initiating device type is addressable?

• A. Conventional
• B. Conventional-addressable
• C. Analog-addressable
• D. All of the above

Answer: (C)

The important idea is that an initiating device is addressable if the control panel can assign it a unique point address and communicate with it individually. Conventional devices, like simple door contacts, aren’t capable of reporting their identity or status beyond a zone’s overall state; the panel just knows the zone is open or closed.

Analog-addressable devices are designed to be on a smart loop where each device has its own address and can report not only alarm status but additional diagnostic data and device type. This allows the panel to know exactly which device triggered and even gather details about that specific device, which greatly aids troubleshooting and system management.

There isn’t a standard category called “conventional-addressable,” and “All of the above” would imply conventional devices are addressable as well, which isn’t correct. So the best fit is analog-addressable.
