When installing microwave transceivers in an interior intrusion system, how should the units be mounted?

When installing microwave transceivers in an interior intrusion system, the best practice is to mount the units toward or away from the transceivers. This orientation allows for optimal coverage and detection capabilities. Microwave transceivers emit signals that bounce off objects in their path; therefore, positioning them correctly ensures that the transmitted signals effectively detect intruders by minimizing blind spots within the monitored area.

Orienting the units appropriately can enhance the sensitivity and range of the detection system, enabling it to accurately monitor movement across designated spaces. This ensures that the area is adequately protected and that the transceivers can respond to potential breaches efficiently.

The other options do not provide the same level of effectiveness in coverage. Mounting at the highest point in the room might not account for the specific layout or obstacles that could block signals. Keeping transceivers close to the main control unit may hinder their detection range and create potential interference. Lastly, installing them at a downward angle could lead to missed detections, as microwaves travel in a straight line and are best utilized when aligned appropriately rather than angled downward.
