What function should a perfect tunnel emergency communication broadcasting system have?
What function should a perfect tunnel emergency communication broadcasting system have?   J&R believes that the tunnel emergency communication broadcasting system can broadcast background music, news, publicity knowledge, etc. at various locations within the tunnel, making it a tool for improving the production environment, enhancing information exchange, and improving spiritual culture. In the event of an emergency, when an emergency evacuation is required, the ground dispatching commander can use the system to send instructions to the scene in a voice-activated manner, directing the field personnel to evacuate the dangerous area quickly, orderly, and safely. On-site personnel can also call, talk and report on-site at any terminal in the tunnel to minimize the impact of disasters and secondary impacts during the post-disaster rescue process. More specific reference to the following system features: 1. Emergency broadcast It can be inserted and broadcast at any time and at any time. It can perform emergency broadcasts on individual areas, multiple areas and all areas as needed, and issue relevant instructions at the first time to improve production efficiency and rescue efficiency. 2, publicity broadcast Can play background music, Safety awareness, etc. You can broadcast different content according to specific requirements, or you can record your own broadcast content. 3. Timed broadcast According to the production needs and related requirements, single or multiple broadcast tasks executed by time, date, month, and quarter can be set. When the specified time is reached, the system will automatically execute all the specified tasks without manual operation, and truly realize unattended operation. 4, full duplex voice intercom In the event of an emergency, the system can directly call the relevant personnel, and directly talk to the voice intercom in the tunnel, which is convenient for work contact. 5, fault online diagnosis It can remotely check the working status of all the main and sub-speakers. Once the communication cable is interrupted or the intrinsically safe speaker fails, it can automatically prompt the fault location and other information for easy maintenance. 6, self-organizing system The intrinsically safe speakers are interconnected by a dedicated network cable or a dedicated optical cable, and a full-duplex communication system can be formed without a dispatching station. In addition, a half-duplex session can be performed between the amplified telephones connected to the intrinsically safe speakers to form a local communication system. 7. Linkage with security monitoring system The system can access the alarm signal generated by the safety monitoring system (such as gas over-limit, water-permeable, etc.) and send an alarm signal in the first time. 8, recording function This system supports all the calls to form a recording file, and the saving time can be set as needed. 9, remote monitoring function The system dispatcher can instantly monitor the sound around the speakers as needed. 10, volume adjustment The system can remotely adjust the call volume and playback volume of the main and sub speakers to achieve a satisfactory call. 11, voice real-time broadcast The system can collect other audio sources as needed and forward them to the designated receiving area at the same time. The mining source can be any audio file or device. 12, online upgrade function The system supports online upgrade, remote update and configuration, and it is convenient to upgrade the system and update the software. 13, power off broadcasting Both the intrinsically safe speaker and the amplified phone in the system can be configured with a backup power supply, which can ensure that the system works normally for no less than two hours in case of power failure. 14, docking various communication systems Flexible networking, can be connected with the existing communication dispatcher to achieve seamless communication between the phone and the speaker; multiple communication systems can be accessed. 15, hot standby The system supports dual-system hot backup. When there is an abnormality in the system, the backup system can be quickly switched to prevent data loss or loss of control and ensure system reliability.   To achieve the above functions, such a tunnel-specific broadcast system should be composed of a SIP server, a voice gateway, a waterproof industrial telephone terminal, a power amplifier, an IP66 waterproof speaker, a network cable, and the like.

J&R Explosion Proof Telephone Play An Important Role In Improving Communications In Underground Pipe Gallery
J&R is delight to share with you that our ATEX Certified intrinsically safe Explosion Proof telephone has been installed in underground gas pipelines to improve the communication systems in underground.     As we all know, pipelines conveying flammable or explosive material, such as natural gas or oil, pose special safety concerns and there have been various accidents. To improve the effective communication and safety in underground pipe gallery areas, it is very necessary to install some emergency telephones, especially some intrinsically safe explosion proof telephones.   J&R’s ATEX Certified intrinsically safe Explosion Proof telephone is specially designed for voice communication in the hostile environment where reliability, efficiency and safety are of prime importance. The telephone can handle the large temperature differences found outdoors, high humidity, exposure to sea water and dust, Corrosive atmosphere, Explosive gases & particles, as well as mechanical wear and tear, making it perfect for use as an emergency telephone. Below are some main features:   - Standard Analogue or VoIP/SIP Telephone - Corrosion resistant aluminum alloy die casting housing - Power supply: Phone line powered (Analogue) l Power-Over-Ethernet/PoE (SIP-VoIP) - With NPT conduit entries and Type 3 / IP67 environmental ratings - Certificated for Dust & Gas - Zone classification: (For explosive gas atmospheres Zone 1 and Zone 2. For IIA, IIB explosive atmosphere. For dust Zone 20, Zone 21 and Zone 22.) - Suitable for temperature class: T1 ~ T6. - Impact of protection: IK10 according to EN50102 - The main keypad features 15 buttons (0-9, *, #, Redial, Mute, Last Number Redial) (Completely programmable weatherproof keypad designed to be used with gloves) - Handset with Noise canceling microphone, for effective communication from noisy areas (Armored SS cord stands up to rough treatment, optional for black curly cord ) - Hermetically sealed non-contact hook sensing switch improves system reliability - Ringing sound pressure level Approx. 90 dB(A) at 1m distance - Mounting: Wall/column/structural - ATEX, CE, FCC, RoHS, ISO9001 compliant   If you are also looking for some explosion proof telephones or industrial emergency telephones for any of your project, J&R always welcome your inquiry and will tailor our solution to meet your specific needs.

Lastest company news about J&R Heavy Duty Telephones have been installed in Cowes, Isle of Wight in the UK 2018/01/19
J&R Heavy Duty Telephones have been installed in Cowes, Isle of Wight in the UK
J&R pleased to share with you one more Project News that our Heavy Duty Weather Resistant Telephones have been installed in Cowes, Isle of Wight in the UK.   Cowes is an English seaport town and civil parish on the Isle of Wight. Cowes is located on the west bank of the estuary of the River Medina,facing the smaller town of East Cowes on the east bank.   The two towns are linked by the Cowes Floating Bridge, a chain ferry.The population was 9,663 in the 2001 census, which doubles during the regatta in early August.The population at the 2011 census was 10,405.   Charles Godfrey Leland's 19th century verses describe the towns poetically as "The two great Cowes that in loud thunder roar/This on the eastern, that the western shore".   Cowes has been seen as a home for international yacht racing since the founding of the Royal Yacht Squadron in 1815.It gives its name to the world's oldest regular regatta,Cowes Week, which occurs annually in the first week of August. Later, powerboat races are held.   Much of the town's architecture is still heavily influenced by the style of ornate building that Prince Albert popularised.   J&R always very glad to hearing the great feedback from our clients, and target to do our best to provide the most suitable phone models and the best solution to meet clients’ different project requirements.   J&R also very happy & appreciate that if all the clients could share the installation pictures of their projects with us.
