Firefighter Audio Light PASS both can indicates the direction of the lights and call for help two functions, to achieve a dual-purpose machine. Firefighter Audio Light PASS in the ultra-loudness, ultra-small size, the lightest quality, based on the use of imported high-strength transparent bullet-proof plastic and HP ultra-high brightness cold light source, the distance greater than 1500m, greatly improved its position warning effect, And the perfect unity of the position lights, thereby reducing the weight of the personnel to wear and reduce the maintenance workload, and cost savings.
The Firefighter Audio Light PASS device is composed of a clock timer, a micro-motion sensor, an alarm and a strong alarm automatic / manual controller, tone frequency conversion circuit, piezoelectric volume output circuit and under voltage warning circuit. Display and other functions.
It overcomes the shortcomings of the existing caller, such as large volume, single function, unreliable circuit, bulky mechanical switch, sound hole water, easy to cover and no azimuth indication function.
1, the luminous intensity of up to 1.46 × 105cd / m2;
2, the location of visual distance lights: night under ≥ 1500m;
3, azimuth light strobe frequency ≥ 1 times / S;
4, the lower corner of the cavity design, not easy to cover;
5, strong alarm sound greater than 98dB, to adapt to complex environments;
6, the overall structure of explosion-proof design, waterproof sealing performance;
7, yellow light under voltage warning to remind the timely replacement of batteries;
8, magnetically controlled pressure bar split power switch, easy to number, carry;
9, shell seismic, high temperature, good light transmission;
10, bright red flashing bright, highly transparent shell, through the fog is good, and do position lights use, visual distance greater than 1500m.
