1. Function introduction
It can effectively prevent the occurrence of secondary accidents during the on-site handling of traffic accidents, and is a barrier to ensure the safety of police personnel on site. When using the anti-intrusion alarm equipment, simply remove the alarm detection ring from the main equipment and place it on the front cone of the accident site. When a vehicle breaks into the scene of an accident, for example, after touching the cone, the early warning induction ring sends out a wireless alarm signal, and the back-end alarm and the portable alarm receive the alarm signal, sound and light and vibrate to give an alarm, prompting the on-site police officers in time Avoid accidents.

 
2. Equipment features and advantages
1. It is easy to carry, simple to use, and it only takes 1-3 minutes to arrange the anti-intrusion site.
2. The work is safe and reliable, and the alarm is only delayed for 100 milliseconds, which is equivalent to a synchronous trigger.
3. The communication distance is long, the linear distance is as long as 600 meters, and the relay can be used to increase the communication distance, which can reach more than 3 kilometers.
4. The ultra-low power consumption design of the early warning device can work continuously for more than 15 hours after a full charge, which is enough to meet the needs of long-term on-site work.
5. Unlimited transmission uses the 433MHz industrial frequency band, which has strong anti-interference ability. The detector and warning device self-check failure prompts.
6. The main charging box is not only the carrier of the early warning device, the alarm repeater (main alarm headlight), and the alarm, but also its charger. This design is simple to maintain, flexible in use, and compact in structure, and truly realizes fool-like operation.
7. The sensitivity of the early warning ring can be adjusted (customized according to customer requirements before leaving the factory), suitable for various road environments and on-site, effectively avoiding false alarms caused by interference.
8. Early warning devices, alarm repeaters, and alarms are all equipped with low-voltage alarms to remind users to charge the equipment in time.
9. Shell protection level: early warning device IP65 alarm repeater IP65
10. Alarm: IP54; charging main box: IP53
11. The equipment has passed high-voltage testing and is safe and stable in use.
12. The strobe light alarm adopts a double-layer high-transmittance lamp shell, and the base adopts a metal base. Durable.
 
3. Functions and parameters:
1. It is composed of an early warning device, a preset cone (provided by the user), a main charging cabinet, a high-power relay alarm and an alarm, and a long-sighted distance warning light.
2. The early warning device can detect by means of vibration, displacement and acceleration of gravity. Through intelligent judgment and wireless digital transmission technology, it can detect motor vehicles that have broken into the alert area due to various reasons.
3.2 The early warning device detects by means of vibration, displacement and gravitational acceleration, and detects motor vehicles entering the alert area due to various reasons through intelligent judgment and wireless digital transmission technology.
4. It can take the initiative to prevent sound and light warnings in advance, prompt motor vehicles to enter illegally, and remind vehicle drivers to take quick measures to avoid accidents.
5. The early warning device can wirelessly send a warning signal to trigger the sound, light, and vibration of the alarm worn by every police officer on the scene, prompting the on-site staff to quickly evacuate the scene, avoiding injuries and secondary accidents due to intrusion of motor vehicles.
6. The early warning device can trigger the on-site alarm repeater to emit sound and light, reminding other on-site personnel who are not wearing the alarm to avoid intruding vehicles and quickly evacuate to a safe area.
7. Usage: outdoor use, portable alarm, wireless networking, wireless transmission and reception and control, high-power alarm.
8. Working mode: the early warning device is placed on the preset cone and works automatically on the road without supervision.
9. Early warning mode: passive alarm for collision and displacement, sound control output of siren.
10. Equipment material requirements: the alarm is made of PC polycarbonate high-strength engineering plastic, and the alarm is made of ABS high-strength plastic, which is strong and durable.
11. Networking range: wireless networking ≥5.
12. Wireless alarm transmission and reception distance: early warning device ≥ 600 meters; alarm repeater ≥ 600 meters; alarm device ≥ 600 meters;
13. The early warning device can increase the relay, and the transmission distance can reach more than 3 kilometers.
14. Lamp life: 100,000 hours.
15. Continuous use time requirements: early warning device ≥ 15 hours, alarm relay ≥ 15 hours, alarm ≥ 15 hours.
16. Equipment alarm volume: alarm repeater> 120 decibels.
17. Alarm> 75 decibels
18. Early warning device: rain-proof, anti-corrosion, impact rolling, 2 meters high fall without damage.
19. Working environment: It can work continuously for a long time in the environment of -20℃～+60℃ all weather without any influence.

Four, instructions for use
Turn on the switch on the side of the signal transmitter ring, and the super bright warning light flashes at the same time.
Put the signal transmission ring on the ice cream cone road cone, and turn the side with the super bright warning light toward the direction of the oncoming traffic to warn the passing cars.
Turn on the switch of the shoulder light sound and light alarm receiver, and the warning light flashes at the same time, and it is clamped near the shoulder. At this time, the entire system is working normally.
Remarks: Each signal transmitting ring and shoulder light receiver will be automatically connected, and the network will be automatically connected, without cumbersome code matching. Each signal transmitting ring and shoulder light receiving alarm can be used as a relay, doubling the distance between arming and wireless alarm.
