A siren could be directly connected to which of the following outputs?

A siren can be directly connected to a wet output because a wet output refers to a connection that provides voltage directly to the device, typically to power devices that require a certain amount of current and have low impedance. In this case, a siren often requires direct power to operate effectively, making a wet output suitable for powering it.

Wet outputs generally allow for the direct connection of devices like sirens, which is essential for their operation, as they usually need a continuous power supply to function.

In contrast, dry outputs do not provide power; they usually serve as a switch closure that operates based on the status of another device. Pulsed outputs provide intermittent signals rather than continuous power and can be used for signaling, which might not be ideal for a siren that needs constant power. Buffered outputs involve signal processing, meant for low-power signaling rather than direct device operation. This further highlights why a wet output is the appropriate choice for connecting a siren.
