ZONICESOUND Public Address & Professional Audio Power Amplifiers FAQ Handbook (V1.0)

I. System Architecture & Transmission Modes

Q1: Is your public address system analog or IP network-based? What are the differences?

Standard Reply

ZONICESOUND supplies both analog public address systems and fully digital IP network PA systems for flexible selection based on project budget, scale and intelligent requirements.

• Analog System: Low cost, rapid deployment, suitable for small-scale projects (kindergartens, mini supermarkets) with constant-voltage transmission (70V/100V).

• IP Network System: Supports remote management, multi-level zoning, mobile APP control, fire alarm & monitoring linkage, ideal for medium-to-large projects such as schools, hospitals and metro stations.We can provide a free comparison sheet of the two solutions to help you make the optimal choice.

Q2: What network requirements does IP PA impose? Will it interfere with the existing office network?

Standard Reply

ZONICESOUND IP PA adopts independent audio stream transmission, with each terminal consuming only 64~128 kbps bandwidth, exerting minimal pressure on the network.Recommended configurations:

• Small projects: Shared with office network with VLAN isolation configured;

• Medium & large projects (campuses, factories): Dedicated PA switches deployed separately to guarantee stability and security.We offer network topology templates and cooperate with weak current contractors for cabling design.

II. Fire Alarm Linkage & Emergency Broadcasting

Q3: Can the PA system connect to fire alarm panels? Does it comply with national standards?

Standard Reply

Fully compatible! Our systems fully conform to GB50116-2013 Code for Design of Automatic Fire Alarm System, featuring:

• Fire emergency cut-off interface (dry contact / 24V signal);

• Automatic interruption of background music upon fire alarm, mandatory broadcast of pre-recorded evacuation voice across all zones;

• N+1 backup host to ensure uninterrupted operation during emergencies.

Q4: Is fire emergency broadcasting available after power failure?

Standard Reply

Yes. We offer two reliability solutions:

1. Built-in UPS power supply for main host (standard or optional accessory), sustaining operation for no less than 30 minutes after power loss;

2. Local storage & backup power at terminals (IP terminals equipped with SD card + DC12V battery). Local fire voice can still play even when the network disconnects.This design is highly recommended for critical areas such as underground parking lots and tunnels.

III. Zone Control & Functional Applications

Q5: Is independent broadcasting achievable for each classroom or floor?

Standard Reply

Absolutely. ZONICESOUND PA systems support unlimited software-defined zones, where each physical terminal functions as an independent zone.Examples:

• Schools: Separate broadcast for every classroom; principal announcements can target the whole campus, specific grades or single classes;

• Hospitals: Zonal management for outpatient departments, inpatient wards and pharmacies to avoid audio interference.The maximum zone quantity is only limited by server performance; regular projects can operate over 500 terminals smoothly.

Q6: Does the system support scheduled class bells and background music playback?

Standard Reply

Supported. Schedule configurations are accessible via DX-VS10 PA management software, including:

• Recurring scheduled tasks (daily / weekly cycles);

• Multiple audio source options (MP3, microphones, external CD players);

• Zoned execution (e.g., background music for canteens during breaks, silent mode for teaching areas).Excel timetables can be imported to generate a full-year bell schedule with one click.

IV. Product Selection & Installation Adaptability

Q7: Which loudspeakers are for outdoor use? Are they waterproof?
