Intercom, broadcasting, alarm linkage are unified on a single IP platform, eliminating system fragmentation and ensuring clear, reliable command in critical moments.
Designed for hazardous and explosion-prone areas, ensuring stable communication in flammable, explosive, and high-noise environments.
One-button alarm and automatic emergency broadcasting, integrating with fire alarm, video surveillance systems to significantly reduce response time.
Industrial-grade design adapts to complex working conditions and ensures continuous operation 24/7.
Heavy industry plants involve flammable, explosive, and toxic hazards, placing extremely high demands on the reliability, stability, and availability of communication systems to ensure personnel safety and effective emergency response.
High noise levels and widely distributed plant areas limit the effectiveness of traditional PA and intercom systems, resulting in unclear audio, reduced coverage, and unreliable communication in critical situations.
Emergency handling often relies on manual notification, which delays information delivery and prevents timely coordination with safety systems such as fire alarms and gas detection, reducing overall emergency response efficiency.
Conventional analog systems rely on complex point-to-point cabling, resulting in high installation and maintenance effort. System expansion or upgrades often require rewiring, leading to long downtime and high upgrade costs.
The SPON heavy industry plants solution is based on an IP network architecture, integrating broadcasting, intercom and emergency linkage for unified plant-wide communication management.

Centralized management and zoned dispatching
One-button alarms and emergency broadcasting
Industrial-grade design for 24/7 operation

1. Zoned or plant-wide broadcasting to process units, tank farms, and pipe racks.
2. Real-time intercom with production units for operational and safety commands.
3. One-button emergency broadcasting integrated with fire alarm systems.
4. Automatic logging for auditing and incident traceability.

1.Accurate delivery of daily production and safety instructions.
2.One-touch calling to the command center in case of abnormal situations.
3.Supports participation in remote meetings and cross-department collaboration.

1.In high-noise environments, production notifications and safety warnings are broadcast through high-power horn speakers or column speakers.
2.Integrated with fire alarm and gas detection systems to automatically broadcast emergency instructions for leaks or fires.
3.On-site personnel can quickly call for assistance via protective intercom terminals.

1.Broadcast shift start/end reminders, safety regulations, and emergency evacuation instructions.
2.In the event of an incident, promptly deliver large-area emergency broadcasts through column speakers.
3.Integrated with video surveillance systems to provide voice warnings for abnormal behavior.

1.Enhance the factory’s perimeter security by working with cameras and intrusion detection systems to achieve proactive protection and rapid response.
2.The IP horn speaker features high sound pressure output (High SPL), delivering clear and penetrating warning or broadcast audio across open areas and noisy factory perimeters, ensuring effective communication.
