product description:

l BDJ-Ex explosion-proof walkie-talkie is designed to meet the extremely special environment of IIB gas group and flammable dust;

l The manufacture meets the requirements of GB3836-2010 standard, and adopts the scientific explosion-proof structure to meet the requirements of intrinsic safety explosion-proof;

l The walkie-talkie and the base station host form a wireless dispatching command system, which can realize the intercom function, the call function, the group call function, the automatic power saving function, and the low voltage prompt function;

l The squelch level can be set by software to control the influence of noise;

l TOT transmission time limit function, launch timeout prompt function, to avoid damage to the host without receiving long-term transmission;

l Broadband (25KHZ) and narrowband (12.5KHZ) are available.

 

Features:

l It can be used in explosive gas hazard sites in Zone I and Zone II;

l Powerful strict explosion-proof standard requirements, using advanced intrinsically safe limiting circuit, even under the most unfavorable conditions, the power will not exceed 3.5W and cause danger;

l The outer casing is specially anti-static treatment to prevent the possibility of static electricity accumulation. The outer casing is made of cushion rubber material to absorb the impact energy when falling, to prevent damage to the machine;

l Dual mode communication mode, read and write frequency encryption, analog sub audio / digital sub audio;

l Powered by explosion-proof NiMH battery, longer standby time;

l High transmission power is achieved at low power supply voltage, thus reducing the size of the battery and miniaturizing the whole machine.
