The BKTS2 Sound and Light Broadcasting Telephone is a rugged wall-mounted communication terminal designed for industrial sites where ordinary telephones cannot deliver reliable performance. It is built for high-noise, high-dust, humid, outdoor, and semi-outdoor environments where clear calling, strong audible alerting, and visible warning signals are essential for daily dispatching and emergency response.

As a wall-mounted industrial telephone, the BKTS2 saves floor space, keeps the communication point fixed in a visible location, and allows workers to quickly identify and access the device in tunnels, workshops, ports, mines, utility corridors, and production areas. Its integrated horn speaker and LED strobe light make it more than a simple telephone: it works as a calling terminal, alerting device, broadcasting point, and emergency communication endpoint in one compact unit.

Product Overview

Integrated Wall-Mounted Industrial Telephone Design

The BKTS2 is designed with a molded wall-mounted body structure, a composite new-material housing, imported cold-rolled steel front panel, and industrial-grade components. This structure improves impact resistance, installation stability, and long-term durability in demanding locations.

The wall-mounted design is especially suitable for fixed communication points in industrial passages, control zones, equipment rooms, tunnel walls, platform areas, and outdoor working sections. Compared with desktop or portable devices, a wall-mounted telephone can be easier to find, harder to misplace, and more suitable for emergency call access in a defined operating area.

Sound and Light Alerting in One Device

The BKTS2 integrates a 30W horn speaker and built-in LED flashing light into one unit. When an incoming call arrives, the horn speaker amplifies the ringtone while the LED strobe flashes, creating both audible and visual alerts. This dual reminder helps reduce missed calls in noisy construction sites, plants, tunnels, mines, and port environments.

This all-in-one design also simplifies installation. Traditional amplified telephone systems often require the telephone, external speaker, and warning light to be installed separately. BKTS2 combines these elements into a single wall-mounted terminal, helping reduce wiring complexity, installation time, and maintenance workload.

Communication Modes and System Compatibility

SIP and Analog Options

The BKTS2 can be configured with SIP network communication or analog telephone communication, allowing it to match different site requirements. SIP mode is suitable for modern IP PBX, dispatching, paging, and unified communication systems, while analog mode can be used in projects that still rely on traditional telephone lines or analog exchange systems.

This flexibility makes BKTS2 suitable for both new communication system deployments and retrofit projects. It can be installed as part of a larger industrial telephone network, emergency dispatch system, tunnel communication solution, or site-wide voice broadcasting system.

Broadcast Calling and Two-Way Intercom

After an incoming call is answered automatically, the caller can broadcast voice instructions through the 30W horn speaker to the surrounding area. This is useful when supervisors, control rooms, or dispatch centers need to issue safety notices, work instructions, or urgent warnings to nearby personnel without waiting for someone to pick up the handset.

The device also supports two-way communication through its intercom function. Workers can use the talk button to communicate back with the caller, enabling both one-way public addressing and practical two-way voice interaction from the same terminal.

Core Functions

Sound and Light Linked Incoming Call Reminder

In high-noise environments, a standard telephone ring may be difficult to hear. BKTS2 solves this problem by linking the incoming call signal with both horn speaker ringing and LED strobe flashing. The result is a stronger alert that can be noticed by workers even when machinery, vehicles, ventilation systems, or production equipment create continuous background noise.

The 30W horn speaker provides high-volume audio output for wide-area ringing and broadcast coverage, while the LED warning light improves visibility in workshops, tunnels, equipment zones, and outdoor areas where hearing alone may not be enough.

Automatic Answer After Ring Counting

BKTS2 includes an intelligent incoming call processing function. The system counts incoming rings and can automatically answer the call after the factory-set number of rings, typically after 3 to 5 rings. Once connected, the calling party can immediately speak through the horn speaker for broadcast paging.

This function is valuable when no operator is standing next to the telephone, but the control room still needs to deliver time-sensitive instructions. It helps avoid missed calls and supports faster communication during urgent or high-workload situations.

Automatic Hang-Up with Busy Tone Detection

After the call ends, BKTS2 can detect the busy tone and automatically hang up. This reduces the need for manual operation and helps keep the terminal ready for the next call. In unattended or semi-attended industrial areas, automatic hang-up improves communication efficiency and reduces the risk of lines remaining occupied.

Technical Features

Rugged Housing and Industrial Materials

The telephone body uses a composite new-material housing with an imported cold-rolled steel panel. The molded structure helps protect the internal communication components from physical impact, harsh handling, and challenging operating conditions.

This rugged construction makes the device suitable for industrial sites where vibration, dust, moisture, accidental impact, and temperature variation may affect normal communication equipment.

IP65 Weatherproof Protection

BKTS2 reaches IP65 protection level, helping protect the device against dust and water ingress. It is designed for waterproof, moisture-resistant, dustproof, and anti-freezing performance in demanding industrial and outdoor environments.

The device can be used in humid sites such as underground utility tunnels, ports, docks, offshore-related facilities, and other environments exposed to moisture or salt mist. Its weatherproof construction helps support stable long-term operation where ordinary telephones may fail.

Pre-Stored Number and Auto Dialing Support

BKTS2 supports pre-stored number dialing, allowing the device to call a predefined control room, dispatch center, emergency desk, or management office. This makes it easier for on-site personnel to contact the correct department quickly during operational issues or emergencies.

When integrated into a site communication system, pre-stored dialing can simplify user operation, shorten response time, and reduce errors caused by manually dialing long numbers in stressful or noisy environments.

Typical Applications

Transportation Tunnels and Utility Corridors

BKTS2 is suitable for metro tunnels, high-speed railway tunnels, highway tunnels, and urban underground utility corridors. These environments often require reliable wall-mounted communication points for maintenance, emergency reporting, dispatch coordination, and public safety operations.

The combination of IP65 protection, strong audible alerting, LED flashing, and automatic answer makes the device practical for long corridors and enclosed spaces where humidity, echo, background noise, and limited visibility can make ordinary communication difficult.

Mines, Power Plants, Steel Plants, and Chemical Facilities

In mines, metal mining areas, coal mine facilities, power plants, substations, steel mills, chemical plants, and coal preparation plants, communication devices must remain stable under dust, noise, vibration, and demanding operating schedules. BKTS2 provides a fixed wall-mounted calling point that can support both routine dispatching and urgent announcements.

The 30W horn speaker helps deliver clear audio instructions across noisy spaces, while the LED strobe light increases the chance that workers notice incoming calls or alerts even when wearing protective equipment or working near loud machinery.

Ports, Docks, Ships, Oilfields, and Outdoor Sites

BKTS2 can also be deployed in ports, docks, ship-related work areas, oilfields, outdoor industrial yards, and other weather-exposed locations. These places often require communication devices that can handle moisture, salt mist, wind, dust, and changing temperatures.

The integrated wall-mounted structure helps create a reliable fixed communication node for command centers, site supervisors, maintenance teams, and emergency response personnel.
