Emergency public address system specification

(Summary description)

Information

      1. The fire resistance of the connector shall comply with the relevant provisions of IEC60268-11 or IEC60268-12.
      2. With 24V or 220V emergency standby power supply, the active and standby power supply switching time is no more than 1s. The emergency backup power supply can support at least 15 minutes of emergency broadcast. If the batteries are used as a backup power source, they should be equipped with an automatic charging device.
      3. The power rating of the power amplifier for emergency public events is not less than 1.5 times the sum of the power of all the speakers it drives. The total power capacity of the power amplifier for emergency public emergency transmission must meet the requirements of all broadcast zones simultaneously issuing emergency broadcasts, instead of only meeting the requirements of several adjacent partitions.
      4. Emergency broadcasts of public emergencies should have the highest priority. The system shall be capable of playing an alert signal or an alert voice file to the alert zone within 3 seconds of the operator placing the system in an emergency or receiving a signal from the fire alarm and other alarm systems, regardless of the current state of the relevant alarm zone (including shutdown) And hibernate).
      5. The volume of emergency broadcasts for public events should be automatically adjusted to the maximum volume allowed by the system.
      6. When all broadcast service areas need to manually issue emergency public emergency broadcasts at the same time, they should be able to click the button (only need to operate a button/button/switch to enter the emergency broadcast state).
      7. Speakers and wiring in the broadcasting area with fire hazards should be flame retardant.
      8. In the broadcasting area with hidden dangers of water and fire disasters, the broadcast speakers should pass the waterproof certification of level 6 or above, so that they can still work under the conditions of short-term spraying (such as automatic sprinkler system startup).
      9. The rated power of a single speaker (or sound column) for emergency public events is not less than 3W.
      10. In public places such as walkways, halls, restaurants, etc., the speaker should be configured to ensure that the walking distance from any part of the floor to the nearest speaker does not exceed 15m. Speakers should be provided at the intersection of the walkway and at the corner. The last speaker at the end of the walkway is no more than 8m from the wall.
      11. The failure of a single power amplifier should not lead to the subversion of the entire Shenzhen public broadcasting. Otherwise, the master/slave amplifier and the corresponding automatic switching device should be configured.
      12. Failure of a single speaker should not cause the entire broadcast partition to fail, otherwise it should be discovered in time.
      13. The system should be broadcast within 10 seconds after the main power or backup power is turned on.

Listeners need to know how to operate the system and troubleshoot any issues they may encounter. Developing clear and practical training materials and resources, as well as providing prompt response to listener queries, significantly contributes to enhancing service quality. Ensuring System Stability and Reliability The stability and reliability of the system are crucial concerns for listeners. To ensure these, regular maintenance and updates must be performed, and high-quality hardware and software should be used. Additionally, providing round-the-clock technical support for any potential issues that may arise is crucial. Delivering Personalized Services Each listener has unique needs, so providing personalized services is key to enhancing service quality. This may involve providing customized solutions for their specific requirements or offering specialized training and support for their unique needs. Establishing Effective Feedback Mechanisms Finally, establishing effective feedback mechanisms is crucial to enhancing the service quality of public broadcasting systems. Listeners should have an opportunity to provide feedback on the service they receive, highlighting any issues or suggestions they may have. Collecting and analyzing this feedback allows businesses to identify shortcomings in the service provided and take corrective actions.   Conclusion Service quality management of public broadcasting systems is an essential aspect of customer satisfaction and retention. The broadcasting system must be designed to meet the needs of the target audience, taking into account listener feedback, ensuring ease of use, frequency control, sound quality, noise level control, scene form control, space management, programming content diversity, channel openness and resource integration flexibility factors, among others, should all be taken into consideration when designing public broadcasting systems to ensure that they meet customer needs.
