RHJ619, a firefighter's rescue device, has two functions: orientation lamp and rescue device. It realizes one machine and two functions. On the basis of super high loudness, super small volume and light weight, the caller adopts the original imported high strength transparent bullet-proof glue and HP super high brightness cold light source from the United States. The distance is more than 1500m, which greatly improves the effect of its azimuth warning, realizes the perfect unification of the caller and the azimuth lamp, thus reduces the wearing weight and reduces the wearing weight of the personnel. The workload of maintenance is reduced and the cost is saved.
Scope of application
It consists of clock timer, micro-motion sensor, early warning and strong alarm automatic/manual controller, voice frequency conversion circuit, piezoelectric output circuit and under-voltage alarm circuit. It has many functions such as automatic alarm, forced alarm, orientation indication, low-voltage display and so on. It overcomes the shortcomings of large volume, single function, unstable circuit, heavy mechanical switch, intake of pronunciation holes, easy covering and no direction indication function of existing domestic rescue devices.
Product characteristics
1. The luminous intensity is as high as 1.46*105cd/m2.
2. Visual distance of azimuth lamp: under night sky (> 1500m);
3. The stroboscopic frequency of azimuth lamp is more than 1/S.
4. The design of the lower side corner acoustic cavity is not easy to cover up.
5. The strong alarm sound is more than 98dB, which is suitable for use in complex environment.
6. Integral explosion-proof structure design, good waterproof and sealing performance;
7. Yellow light under-voltage warning to remind timely replacement of batteries;
8. Magnetically controlled voltage strip split power switch, easy to number and carry;
9. The shell has good shock resistance, high temperature resistance and light transmittance.
10. Red, bright and shining, highly transparent shell, good fog permeability, both prescription
The visual distance of bit lamp is more than 1500m.
