Product catalog summary

Main Features
The JR208-FK-AL telephone is designed with a robust housing made of brushed stainless steel, offering protection level IP65 and advanced noise reduction technology for high-definition calls. It is corrosion-resistant and complies with CE, FCC, RoHS, IK10, IP65, and ISO9001 standards. The device features a full metal keypad, an ABS material handset with a noise-cancelling microphone, and an 83 cm armored cord. It supports hearing aid compatibility and includes a magnetic reed hook-switch. The telephone is designed for flush mounting and simple installation, making it vandal-resistant and suitable for high-risk environments such as parking lots, prisons, airports, and more.

Technical Specifications
The telephone is compatible with standard PABX systems and supports remote programming. It features a programmable auto hang-up timer, automatic dialing with delay, and scheduled dialing for system checks. It includes one relay for remote control of external devices and can adapt to different Analog PABX models. The device is phone line powered, with an operating temperature range of -40˚C to 65˚C and a storage temperature range of -40°C to 75°C. It has a mean time between failures (M.T.B.F.) exceeding 50,000 hours. The operating voltage ranges from 24 VDC to 65 VDC, and the operating current ranges from 20 mA DC to 100 mA DC. The ringer operates at 48 VAC to 90 VAC with a calling frequency of 21 to 54 Hz, and the ringing volume is 80 dB (A) at 1 meter. The dialing method can be set to PD or DTMF mode, with DTMF mode conforming to ITU-T recommendation Q.23. The device offers protection to ITU-T K.21 enhanced levels and can be programmed remotely via DTMF tones or the keypad.

Applications
The JR208-FK-AL can connect to a voice gateway to convert analog signals to SIP signals for use in SIP-based systems. It can also connect to PABX systems to call outside lines through the PSTN. The telephone is suitable for various application scenarios, including metro stations, airports, business centers, bus stations, banks, hospitals, schools, and prisons.
