Factory Telephone with External Beacon & Hooter Knsp-15mt Marine Telephone

FACTORY Telephone with External Beacon & Hooter Knsp-15mt Marine Telephone 
Made of industrial environments that need an intercom telephone which can with stand rough usage & treatment.
Application
The Weatherproof phone will be designed to work on Railway, metro, tunnel,etc. Housed in robust aluminium die case with spring loaded door, it will offer protection against the outdoor environment,vandals resistance and rot resistance.
The unit will meet all the latest European/UK standards for EMC and US FCC, telephony,
waterproofing IP66, and lightening protection together with offering the level of performance and reliability demanded in such an environment. 
 DTMF(Dual Tone Multi Frequency)
Standard and SMART Analogue and VoIP-SIP options available 
 Matching with most PABX,PBX and PAX systems.
 
It is specially designed to use in high wet environment of all kinds of electric power tunnel, with the characteristics of high protection, and low power consumption. A line can support 10 sets of telephones, and the standard of DTMF code sending exceeds 10 kilometers. With 1W speakers built-in, voice is clear and loud. The transmission distance could reach to 10 kilometers without additional power supply.

3. Technical Parameters
Ambient temperature:-30 ~ +60 degreeRelative humidity:10%~95%
Atmospheric pressure: 86~106Kpa Circumstance noise:less than 60dB(A)
Sound level of ringing:over 70dB(A).
Standard frequency:low frequency group:697. 770. 852. 941Hz,
high frequency group:1209. 1336. 1477Hz, frequency deviation:-1.5% ~ +1.5%
If service line is a 3Km signal - level:
Standard frequency:low frequency group:-12dB~-6dB, high frequency group:-10dB~-4dB, level difference between low and high frequency of compound signal:0dB~3dB, the total distortion caused by intermodulation of harmonic wave is lower than the basic level by at least 20dB.
Call transmission index:(5KM)SLR<12,RLR<-1,STMR>10, output impedance is 600 Ohm
Parameters is kept in EEPROM, no losing with power-fail.

4. Function introduction:
Automatic dial-up function: press dial-up keys, 3 ~ 5 seconds for you will be designated to dial the number.
Call time limited: Automatically start seven minutes timing when connecting a telephone. When time is up, phone automatically hangs up in order to prevent lines occupied because of long conversation.
Send address code: Press the answering button when there is a phone call. Then send address code within 2s after answering. When call out, press the call button, send out this phone address code within 1-63s.Achieve the function of delay time through the internal dial-the-code switch.
Turn 1 to ON means delaying 1s. 2 mesns 2s.3 means 4s......6 means 32s.
