Lighting Control Systems & Automation Flashcards

What is the primary function of a photocell (dusk-to-dawn sensor) in a landscape lighting system?

Answer: Automatically turns lights on at dusk and off at dawn based on ambient light levels

A photocell detects ambient light levels and automatically activates the system at dusk and deactivates it at dawn, eliminating the need for manual switching.

Which type of timer is most reliable for landscape lighting because it automatically adjusts on/off times throughout the year?

Answer: Astronomic (astro) timer

An astronomic (astro) timer uses GPS coordinates and an internal calendar to calculate exact local sunset and sunrise times every day of the year, automatically adjusting schedules.

In a low-voltage landscape lighting transformer, what does the 'timer' feature control?

Answer: The scheduled on and off times for the lighting zones

The built-in timer in a landscape lighting transformer allows the installer to program specific on/off schedules for the connected lighting zones.

What is the main advantage of using a multi-zone landscape lighting transformer?

Answer: It allows different lighting areas to be controlled independently with separate schedules or settings

A multi-zone transformer allows separate areas of the landscape (e.g., front yard, back yard, pool area) to be controlled independently, with different on/off times or dimming levels.

Which control method allows a homeowner to adjust landscape lighting using a smartphone app?

Answer: Smart home/Wi-Fi integrated lighting controller

Smart home or Wi-Fi integrated lighting controllers connect to the home network and allow remote control and scheduling via a smartphone app.

What is a 'manual override' feature on a landscape lighting timer primarily used for?

Answer: To temporarily turn the lights on or off outside of the programmed schedule

A manual override allows the user to temporarily activate or deactivate the lighting system outside of its programmed schedule, useful for special events or maintenance.

When integrating landscape lighting with a home automation system (e.g., Control4, Lutron), which protocol is commonly used for low-voltage landscape lighting controllers?

Answer: 0-10V dimming or proprietary smart protocols (e.g., Z-Wave, Zigbee, Wi-Fi)

Low-voltage landscape lighting controllers commonly integrate with home automation via 0-10V dimming signals or wireless smart protocols such as Z-Wave, Zigbee, or Wi-Fi.
