Solar siren uses solar energy to charge the battery that supplies power to the system, and at the same time transmits control signals through wireless or wired means, which truly achieves wireless power supply and wireless signal, improving the installation flexibility of the system, in addition, multiple wireless alarm signals can be built to alert multiple directions at the same time to deter illegal intruders. Wireless alarm can be used as an on-site alarm system. According to the requirements of the system, choose wireless accessories with the same working frequency as the alarm number, and use these wireless accessories to learn the code with the wireless alarm number, which forms an independent work site alarm. The wireless alarm should be installed in the center of the preventive place as far as possible to give consideration to the best receiving effect of all wireless detectors. Note: alarm installation should be kept away from large metal objects or household appliances with high frequency interference as far as possible, and shields such as reinforced concrete walls and fire doors should be avoided.

Features:

Wireless alarm can be used as an on-site alarm system. According to the requirements of the system, choose wireless accessories with the same working frequency as the alarm number, and use these wireless accessories to learn the code with the wireless alarm number, which forms an independent work site alarm. Remote control and accessory learning-press the setting key to hear a sound of "beep", the alarm signal enters the learning state, and then trigger the remote control or detector, and hear two sounds of "beep", indicating that the learning is successful.
