Alarm industrygeneral purposeWireless repeater
Can't be used for wifi signal!!!
The SNC-308 wireless repeater is a 315MHz, 433MH wireless signal amplification and forwarding device. It has the function of learning and storage, and can only forward wireless signals in 2262/1527 encoding format. The wireless receiver has high sensitivity, long forwarding distance, waterproof shell design, can be used indoors and outdoors, and the installation is simple. It is suitable for wireless alarms, wireless beepers, most electric doors and other products, increasing the transmission distance of wireless products, and supporting multiple repeaters to relay and continue. It can be matched with wireless products from most manufacturers. It does not support product data signals such as queuing machines and lora signals. Roll code remote controls do not support either. Please read the technical parameters of this product carefully. 80% electric telescopic doors can be used. Some electric doors are marked with 433MHz, but in fact 430MHz cannot be used.

Repeater application schematic
In principle, the repeater should be installed at the position between the front-end detector and the receiver. This position selection is very important. It is necessary to receive the signal from the detector and transmit the received signal to the receiver. If it is too close to the detector, the receiver may not receive it. If it is too close to the receiver, the signal from the detector cannot be received, which will lead to installation failure. It is necessary to choose a good point between the detector and the receiver. We call it a node. If the node is selected correctly, a repeater can solve the problem. Otherwise, as shown in Figure 2, multiple repeaters relay out
According to Figure 1: first test the reception of the front-end detector signal. After matching the code, the detector transmits the signal and the repeater will respond. If the wall blocks the signal, test whether the detector signal can be reached in the wall and outside the wall. It must be installed at a position where the detector signal can be received. If the host cannot receive the signal, the installation height of the repeater can be adjusted. The higher the installation position, the farther the transmission distance of the repeater
If the distance is too far or there are too many obstacles, one repeater cannot complete the transmission task, and multiple repeaters can be used to relay the transmission. In theory, the first-level relay can transmit the signal from one city to another- Notes on the installation of repeaters1. Don't rush to install when you receive the goods, read the manual first.2. Repeater installation position: between detector and receiver.Node selection is critical, choosing the wrong installation location makes it impossible to fully utilize the repeater.
