ZENITEL STENTO STB 5 3005020060 Flush Mounted Substation

The ZENITEL STENTO STB 5 (Part Number: 3005020060) is a robust and reliable flush-mounted intercom substation. It is a key component of Zenitel’s STENTO product line, which is renowned for its high-quality audio and durability in demanding environments. This substation is typically used as a remote entry point to communicate with a central station or an automatic door/gate controller.

Primary Function: To provide secure, hands-free, full-duplex (simultaneous talk and listen) audio communication in harsh and high-noise environments.

Key Features & Specifications

• Model: STENTO STB 5

• Part Number: 3005020060

• Mounting Style: Flush Mounted. It is designed to be recessed into a wall or panel, resulting in a sleek, low-profile appearance that is more resistant to accidental or intentional damage compared to surface-mounted units.

• Audio Quality: Full Duplex. This allows for natural, telephone-like conversation where both parties can speak and listen at the same time without using a push-to-talk button.

• Durability & Protection:

  • Vandal-Resistant: Built with a heavy-duty metal casing and a robust stainless steel push button to withstand physical abuse.

  • Weather & Environmental Resistance: Typically rated to a high IP (Ingress Protection) standard (e.g., IP66 or higher), making it dust-tight and protected against powerful water jets. It is designed to operate in extreme temperatures and is highly resistant to corrosion, making it suitable for both indoor and outdoor use.

• Call Button: Features a large, prominent, and durable stainless steel call button for initiating communication.

• Microphone and Speaker: Integrated high-quality components designed for clarity even in noisy conditions (e.g., industrial plants, docks, railway platforms).

• Connections: Terminates in a cable with flying leads or a connector for simple wiring to the main intercom system.

Typical Applications

This substation is used in environments where reliable communication is critical and where equipment is exposed to tough conditions. Common applications include:

• Industrial Complexes & Manufacturing Plants: For gate entry control and communication between secure zones.

• Ports & Harbors: At security gates and for communication along quaysides.

• Railways & Metro Stations: On platforms and at entrance gates.

• Parking Garages & Toll Booths: For customer assistance and entry control.

• Prisons & Secure Facilities: At perimeter gates and between secure areas.

• Oil & Gas Installations: In hazardous areas (specific models may be certified for such use).

Breakdown of the Product Code

• ZENITEL: The manufacturer, a global leader in critical communication systems.

• STENTO: The product family name for Zenitel’s range of heavy-duty audio communication equipment.

• STB 5: The specific model identifier. “STB” likely stands for “Substation,” and “5” denotes a specific version or feature set within the STENTO line (often related to its internal electronics and capabilities).

• 3005020060: The unique manufacturer’s part number for ordering this specific flush-mounted variant.

• Flush Mounted Substation: Describes the physical form factor and its role in the system (a secondary station that calls a main station).

System Integration

The STB 5 is not a standalone device. It must be connected to a compatible master station or controller, such as a Zenitel STENTO Central Station or a TCS/ICX system controller. When the call button is pressed, it signals the master station, establishing a communication link.
