Overview

Product Description: The design of BDJ Ex explosion-proof walkie talkie meets the requirements of extremely special environments such as IIB gas group and combustible dust. Its manufacturing complies with the GB3836-2010 standard and adopts a scientific explosion-proof structure to achieve intrinsic safety and explosion-proof requirements; This walkie talkie, in conjunction with the base station host, forms a wireless dispatch command system that can achieve intercom function, single call function, group call function, automatic power saving function, low voltage prompt function, etc. The static noise level can be set through software to control the impact of noise; TOT transmission time limit function, transmission timeout prompt function, to avoid damage to the host caused by long-term transmission without acceptance. Broadband (25KHZ) and narrowband (12.5KHZ) are optional.

Product Introduction

Product Introduction

This walkie talkie, in conjunction with the base station host, forms a wireless dispatch command system that can achieve intercom function, single call function, group call function, automatic power-saving function, low voltage prompt function, etc

The shell has undergone special anti-static treatment to eliminate the possibility of static electricity accumulation and potential hazards

The shell is made of cushioning rubber material to prevent damage to the machine

Dual mode communication mode, read-write frequency encryption, analog sub audio/digital sub audio

Strict explosion-proof standards are required for power, and advanced intrinsic safety limiting circuits are used. Even under the most unfavorable conditions, the power will not exceed 3.5W and pose a danger

High transmission power was achieved at low power supply voltage, achieving miniaturization of the entire machine

Application Scenario:

Can be used in explosive gas hazardous areas in Zone I and Zone II
