True or False: Ceiling-mounted visual appliances have larger candelas than those mounted on the wall.

Ceiling-mounted visual appliances are typically designed to cover a larger area and provide a more dispersed light output than wall-mounted visual appliances. This is because ceiling-mounted devices usually have a larger distribution pattern meant to reach occupants from above, ensuring visibility in various settings.

The requirement for a higher candela rating in ceiling-mounted appliances is driven by the necessity to meet specific visibility standards and provide reliable alerts in emergency situations. The larger candelas ensure that the light produced can be seen from various distances and angles, particularly in larger or multi-room environments.

In contrast, wall-mounted appliances have different visibility criteria and are often designed for specific installations and needs, which can result in lower candela ratings. Therefore, the assertion that ceiling-mounted visual appliances generally have larger candelas than those mounted on the wall is accurate.
