State administration of production safety supervision and management of communication information center producer interphone.
Can through the RFID electronic tag anti-counterfeiting, and query authentication in national safety bureau official website.
Have run backward, safety inspection, emergency alarm, work alone four alarm function, test working status at any time, to ensure the safety of life.
The quality is reliable
Using this authentication for ExibIIBT3 explosion-proof grade, can be used in explosive gas environment 1 zone and 2 zone.
Advanced anti-static plastic fuselage, to prevent a substantial accumulation of static electricity in the machine surface, waterproof, anticorrosion, prevent leakage of the internal circuit is three designs, put an end to all the intercom security hidden danger.
Resistance to drop explosion-proof structure, in the fall behind will not bare battery, prevent accident.
Through five years of accelerated aging experiment and the United States army mark strictly test.
Efficient and convenient
Kind, real-time scheduling, always keep in touch.
Body size, light weight, easy to use, to use for a long time.
Nimh explosion-proof battery 1600 mah this Ann type, about 14 hours work time.
Attachments are: mi and ear mi in the hand, skull headphones, holster, six senior league quick charger for the dangerous sites (not used), save time space.
Backwards (optional)
After entering run backward mode, if the machine is in a state of flat or falling more than set time, the radio will automatically alarm. The interphone to the centralizer, can cancel the alarm.
Safety inspection
Set this function, the control center or other user signal detection, interphone will prompt after receipt of the detection signal, press any key said in a safe state at this time, no response will automatically alarm.
Voice channel to broadcast
Boot and adjust the channel automatically broadcast channel, loud noise, and avoid the wrong operation.
Work alone
To enable this feature, for walkie talkie set separate work time length, each time arrived at the critical time, walkie-talkies, will send out alarm prompt at the same time, the user must press any key, show that in the safe state; Without action, the interphone will automatically alarm.
