A mirrors construction material would interfere with which system portion?

• A. Wireless signal transmission
• B. Physical mounting
• C. Battery life
• D. Panel rating

Answer: (A)

Mirror construction often uses a metal-backed or metallic coating to create the reflective surface. That metal content acts like shielding for radio waves, which are the basis of wireless communication in many alarm systems. When wireless sensors or panels have to communicate through or past such a mirror, the signal can be attenuated, reflected, or blocked, leading to weaker reception or communication dropouts. That’s why the system portion most likely impacted is the wireless signal transmission. The other aspects—physical mounting, battery life, and panel rating—are not primarily affected by the presence of a mirror in the sensed environment. Mounting deals with installation hardware, battery life with power consumption, and panel rating with device specifications and approvals, none of which are directly changed by mirror material.
