Frequently asked questions
Common questions about ACUITY BRANDS from 3G Electric.
What is the operating voltage range for Acuity Brands occupancy sensors available from 3G Electric?
The occupancy sensors in the Acuity Brands line supplied by 3G Electric, such as the *268UHT and *268UJ5 models, operate at 120 to 277 V AC. This range covers common commercial voltages in North America and many international installations. The sensors use passive infrared (PIR) technology and are designed for hard-wired or wireless communication, depending on the SKU. Neutral wire is not required for these units, which simplifies installation in retrofit scenarios.
Do Acuity Brands nLight® companion switches require a neutral wire for installation?
No, the nLight® companion switches stocked by 3G Electric, including models 2592TJ, 2592TS, and 2617W7, do not require a neutral wire. These are low-voltage, hard-wired switches that communicate via the nLight® control system. They are available in ivory or white finishes and feature three-button configurations. The absence of a neutral requirement makes them suitable for replacing standard wall switches in older buildings where neutral wires may not be present.
What types of exit signs does Acuity Brands offer through 3G Electric?
Acuity Brands exit signs available from 3G Electric include plastic lighted models such as the 2889TK and 290H5H. The 2889TK is a non-battery-powered unit with self-diagnostics, operating at 120 to 277 V, with red/green text and a black housing. The 290H5H includes emergency battery backup, supports LED or incandescent lamps, and has a white housing. Both models feature universal field-selectable directional indicators and are designed for ceiling or wall mounting.
Are Acuity Brands occupancy sensors compatible with wireless control systems?
Yes, certain Acuity Brands occupancy sensors supplied by 3G Electric, such as the *268UHT and *268UJ5, are wireless models. These use passive infrared (PIR) detection and have a maximum coverage area of 36 sq ft. They operate at 120 to 277 V AC and do not require a neutral wire. The wireless capability allows integration with building management systems without running additional control wiring, though specific compatibility with third-party systems should be verified against the nLight® platform.
What is the communication method for Acuity Brands nLight® wall switches?
The nLight® wall switches stocked by 3G Electric, including models 2592TJ, 2592TS, and 2617W7, use hard-wired communication. This means they connect directly to the nLight® control network via low-voltage wiring, rather than relying on wireless signals. The hard-wired approach provides reliable, low-latency control for lighting zones and is typical in commercial installations where network stability is critical. These switches are compatible with the nLight® series and require no neutral wire.
Do Acuity Brands exit signs include self-diagnostics features?
Yes, the Acuity Brands exit sign model 2889TK, available from 3G Electric, includes self-diagnostics. This feature automatically tests the unit’s functionality, such as LED operation and power supply status, without manual intervention. The 290H5H model, which has emergency battery backup, also supports self-diagnostics. These capabilities help maintenance teams comply with periodic testing requirements for emergency lighting in commercial and industrial facilities.
