1.1 Safety Instructions
The following safety principles are followed to ensure personal safety and to help protect the product and work environment from potential damage.
 |
When in an airport or other places, it is necessary to prevent the terminal from causing interference to the aircraft communication system. Ignoring this prompt may lead to flight safety issues and even violations of the law. |
 |
When in a hospital or health care place, users need to pay attention to whether there are restrictions on the use of terminal equipment. RF interference can cause the medical device to malfunction, so it may be necessary to turn off the terminal device. |
 |
The terminal device does not guarantee an effective connection under any circumstances, and it is necessary to ensure that the device is powered on and in an area with sufficient signal strength. |
 |
Terminal device will receive and transmit RF signals when it is turned on. Radio frequency interference occurs when you are near a radio or other electronic device. |
 |
Keep the device away from flammable gases. Do not put it near gas stations, oil depots, chemical plants, or explosive work sites. There are hidden dangers in operating electronic equipment in any potentially explosive atmosphere. |

Part Description
5.1 GPRS Wireless Module
GPRS module can be used to communicate with the base stations and help to transfer a variety of instructions, such as: switching ON/OFF, dimming commands, uploading power consumption data, uploading illuminance information, etc.
5.2 Control Module
After booting, the module automatically obtains the command sent by the system to start the dimming strategy. If not set, the module will dim according to the factory default strategy.
5.3 Light sensor (optional)
The light sensor uses a digital light sensor. Its sensing range is adapted to the recognition range of the human eye. After the module joins the NB network, it will upload the illuminance data to the gateway. When the module works offline, it will turn on the lights at 16±6 lux and turn off the lights at 50±6 lux (default setting).
5.4 Dimming
The product has 1 channel 0-10V analog dimming interface and one channel PWM interface. To better accommodate the needs of multiple LED drivers, the default dimming curve is shown in Figure 5.
Application
6.1 Sockets and modules
The module needs to be used with the twist lock light control socket. (According to ANSI C136.41 requirements), the socket is shown in Figure 6.
6.2 Typical Application
FCC Statement
This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions: 1) this device may not cause harmful interference, and 2) this device must accept any interference received, including interference that may cause undesired operation.
Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following age 25 measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TVtechnician for help.
Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
SAR Statement
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment’s normal use should be installed and operated with a minimum distance of 20cm between the radiator & your body.
