Addressable lighting control system: one disadvantage.

Addressable lighting control system: one disadvantage.

• A. More expensive to install due to mains supply and communications cable.
• B. Fault identification is slower.
• C. No central control.
• D. No need for power.

Answer: (A)

Addressable lighting control systems let each fixture be controlled individually over a data network. The main drawback is the higher installation cost, because you must provide both the mains supply and a dedicated communications cable for the control data, along with the necessary controllers, gateways, and network hardware. This added cabling and equipment tends to raise the upfront price compared to non-addressable or simpler dimming setups. The other statements don’t fit as well: these systems typically rely on a central controller or network, so saying there’s no central control isn’t accurate; the luminaires still require power to operate; and fault identification is not inherently slower since digital status feedback can actually speed up locating issues.
