Product Name: Skull Vibration Communication Device-H1m1 (manual) /Fire Fighting Model NO.: H1M1 Color: Silver, Blue, Brown Type: Wireless Earphone Wire Material: PU Communication: Wired Function: Bluetooth, Microphone Jack Diameter: 3.5mm Jack Type: Plug-in Usage: Fire Fighting Trademark: ZHENGZE Transport Package: Carton Specification: 85g Origin: China Product Description Skull vibration communication device-H1M1 (manual)The helmet communication unit is a small and light helmet communication unit specially used in extremely dangerous environments. It is easy to use, enhances personal safety and improves work efficiency;Use a high-sensitivity vibration sensor to collect the vocal cord vibration transmitted to the skull and convert the vibration signal into a sound signal; unlike other traditional headphones, a thin waterproof bone conduction vibration sensor is placed on your head;Due to the unique arm / buckle design, it can be easily and very firmly installed in almost all standard helmets without any tools, without affecting the use of other protective equipment such as breathing mask;The PTT control button converts the vibration signal of the pickup into an ordinary audio signal. After noise filtering, it is amplified to a signal that can be matched by the intercom, and then transmitted to the intercom.The ultra-large button structure design allows even thick gloves or heavy protective clothing (firefighters) to be easily activated.Polycarbonate material strengthens the solid performance of the shell, built-in positive and negative air pressure adjustment device, precise scientific waterproof, mechanical structure design, can withstand extreme water pressure and impact.Helmet communication headsetWeight: 85gPickup: Vibration sensor, noise cancellation 30 dBSpeaker: 32 ohmCable: Spring wire (flame retardant): 4.2mm / 380mm Straight line (flame retardant): 4.2mm / 750mmConnector: Spring wire: 5-core quick-plug typeProtection level: IP67Working temperature: -25… + 63 ºC (continuous)Working voltage: 2,5… 10,0 VDCHumidity: 95% RH, + 63 ºC for 500 hoursPTT control buttonWeight: 210gDimensions (housing): 65 (diameter) × 40 (thickness)Material: Polycarbonate, silicone rubberCable: According to actual useConnector 5 core quick plug typeProtection level: IP67Working temperature: -25… + 63 ºC (continuous)Working voltage: 2,5… 10,0 VDCHumidity: 95% RH, + 63 ºC for 500 hours
