feature

1) Shell of the explosion-proof telephone made of si-aluminium alloy with high  temperature ,electrostatic plastic sprayed surface. good impact resistance.      

2) The telephone adopt stainless steel keypad, which contact resistance≤30ohm,life cycle≥2 million,push force 160-   200grams,defend grade is up to IP67, good hand feeling.

3)Handle adopts imported Pc engineer material, thermostability of the PTFE wire .military noise cancelling microphone.Clear conversation in 115 dB enviroment .

4) Hook adopts magnetic induction switch, life cycle ≥500 thousand Increased safety terminal compartment, to ensure that products explosion-proof and electrical properties.

5) Using integral design faith,integrate basic conversation  ciruit , noise removal circuit.power amplifying ciruit and power cicuitand protection circuit etc. 

 These electronic components of the product adopt famous imported brand and selected by high and low temperature aging test.

6) The telephone network is flexible ,can be setted of its extension set arbitrarily,

    numbers can be changed random . it can add or decrease anytime without restriction . 

     Each telephone is the independent workstation, will break downnot to interfere with the overall system work.

7) Can be set function of amplification call directly or after sevral ring ( 1 to 7 voice can be set ) ,

     or more ring (it can be ring according to the offer of the exchange)    This system with  function of general calling (hundreds reponse to a single call ).

technical parameter

details

First, the phone casing

1)  alloy shell, 800 tons die casting machine casting, the wall thickness of 6mm, weighs about 8KG, high mechanical strength and impact resistance.

2)  shell surface temperature electrostatic spray, antistatic ability is good. Eye-catching colors, 10 years without fading

3)  phone casing patented design requires no separate waterproof cover, beautiful and practical, Patent No.: 1,581,443

4)  shell explosion Waterproof grade: IP65, waterproof and corrosion-proof

Two key components:

5) telephone internal circuit by the Division I independent research and development, the use of internationally-sided integrated circuit, with hair the exact number, call clear, stable and so on.

6)  key components handle, hanging fork, keyboard by the company's own production, strict quality control, sale and fast response

7)  Product keyboard for the Division I patented design, the panel of stainless steel, zinc alloy keys, the contact resistance ≤ 30 ohms, life ≥ 200 million times, pushing the intensity 160-200 grams. Patent No.: 1,754,789

8)  professional waterproof handle, imported PC-proof plastic, Teflon wire, using industrial-grade anti-noise microphone, call clarity in 115dB environment. This handle through international CE certification. CE Certificate Number: PS2010120310-2

9)  products made of zinc alloy fork hanging magnetic sensor switch, life ≥ 50 million times
how to use

1) the same as normal telephone

2) The explosion proof  telephone is generally matched with anti-explosion junction box, anti-explosion publicaddress, anti-explosion amplifier and indoor telephone, all of which we manufactured by ourselves and forming a program dispatch anti-explosion public-address communication systems.and the connection schematic diagram is as follows:

the systemic function feature 

1, the system must be supporting the use of exchanger 

2, all the extension in the systems are avalilable to communication outside through the sysytem exchanger.

3, two-tone dialing system through the keyboard 

4, automatic channel conversation 

5, it can be set parts of outside lines which call in or call out restrict, all the numbers are set by the exchanger

6, single call function 

7, if the phone is not dialed  in 5 seconds, you must pick up the handset dialing again, broadcast to find someone more than 60 seconds, you will hear a busy tone, and you must start again.
