A smoke detector should be programmed as which zone type?

Programming a smoke detector as a Type 9 zone is appropriate because Type 9 zones are typically designated for supervised circuits that monitor the status of the devices. Smoke detectors need to be continuously monitored to ensure they can properly respond to smoke conditions, and a Type 9 zone provides the necessary functionality to alert a control panel when the device goes into alarm, is malfunctioning, or has been disabled.

This classification helps ensure that the smoke detector operates within the established safety protocols, offering an effective response in case of fire or smoke detection. It also allows for specific handling within a security system, so that alerts can be prioritized based on the type of zone and its critical nature. Being able to distinguish the smoke detector zone ensures better management and quicker response in emergencies.
