What component is specifically used for creating alarm zones in various locations?

The component specifically used for creating alarm zones in various locations is indeed the photo beam. Photo beams operate by creating an invisible line between two units, often a transmitter and a receiver, which can detect when an object or person interrupts that line. This makes them particularly useful in establishing distinct zones of protection in a defined area, as they can be strategically positioned to secure entrances, perimeters, and other sensitive locations.

Utilizing photo beams allows security systems to monitor and trigger alarms based on movement in a designated zone, enhancing the effectiveness of the alarm system in identifying potential intruders or unauthorized access. This is especially beneficial in outdoor settings or large spaces where traditional sensors may not be as effective.

The other components mentioned do have their own roles in alarm systems but do not specifically create alarm zones in the same manner. Alarm screens are generally used for user interfaces, active detection systems can encompass a variety of detection technologies, and deep buried cables are more related to wiring and are not directly involved in the zoning of an alarm system.
