Product catalog summary

Description:
The IP Telephone Explosion Proof Telephone is designed with a robust aluminium alloy die-cast body, making it vandal and tamper-resistant. It features a waterproof rating of IP66, ensuring dust and water protection. The telephone includes a full keypad with memory and three programmable buttons, a magnetic reed hook-switch, and a heavy-duty handset compatible with hearing aids and equipped with a noise-canceling microphone. The handset is connected via an industrial-strength armored cord, and the stainless steel keypad maintains waterproof and dustproof integrity. Additional features include a built-in 8-ohm 0.5W speaker with a flashlight, an automatic self-closing door cover, and a temperature range of -20°C to +55°C. The device supports echo cancellation and is powder-coated with a UV-stabilized polyester finish, suitable for hazardous environments such as petrochemical industries, tunnels, marine, and offshore platforms.

Specifications:
The telephone is protected under the classification II 2G Ex db ib IIBT5 Gb, with operational temperatures ranging from -20°C to 55°C. It supports VoIP SIP2.0 and DTMF dialing, with a mean time between failures (MTBF) of 100,000 hours. Call control signaling is managed via VOIP SIP Info (DTMF) and RFC 2833 (DTMF). The power supply is provided through Power over Ethernet (PoE), with auxiliary contacts rated for resistive loads. The device can handle a maximum switching voltage of 125 VAC or 30 VDC and a maximum switching current of 1A. The sound level of the ringing exceeds 90dB(A) at a 50cm distance. The keypad supports speed dialing for three groups of numbers stored in memory. Audio codecs supported include G.711, G.722, and G.729. Network connectivity is via 10/100 Base TX Ethernet with RJ45 connectors, supporting IP protocols such as IPv4, UDP, DHCP, and SIP. LAN protocols include PoE (802.3af), network access control (IEEE 802.1x), HTTP, HTTPS, and SIP2.0. Programming and configuration are managed through a web GUI, with support for DHCP and static IP, remote software upgrades, and centralized monitoring. Echo cancellation is supported by G.167/G.168 codes. The unit measures 290x185x118mm and weighs 10.65kg, with environmental conditions supporting ambient temperatures from -20°C to 55°C, relative humidity from 10% to 95%, and atmospheric pressure from 86 to 106 Kpa. The degree of protection is IP66.

Network Connection:
The telephone connects to the company's IP telephony network system. Before connection, ensure the network system is operational. A direct network connection requires at least one Ethernet port in the workspace. Connect the LAN port to the Ethernet port using a Cat 5 or better network cable.

User Programming:
To program the telephone, pick up the handset, press the storage key followed by the address key (digits 0-9), enter the phone number, press the storage key again, and then hang up.
