Which of the following is an example of an initiating device in a typical alarm system?

Explanation:
Initiating devices are the sensors that detect a condition and send a signal to the alarm control panel to start the alarm sequence. A smoke detector fits this role because it monitors for smoke and, when detected, activates the alarm. The other items aren’t initiating devices: a security camera is primarily for monitoring and would only trigger an alarm if linked to analytics or video-triggered alerts; an emergency exit sign is a passive safety feature; a fire extinguisher is a manual suppression tool, not a sensor that starts the alarm.
