Trinity 16A Bell Press Switch Module

• Functions as the core component for doorbell, buzzer, and access control systems within the versatile Trinity modular range.
• Features a responsive, spring-loaded momentary action, completing a circuit only while the lever is being pressed.
• Designed as a standalone module that clips securely into any compatible Trinity yoke, enabling fully customized control panels.
• Includes a clear, universally recognized bell symbol laser-engraved on the switch lever for intuitive, unambiguous use.
• Allows for the creation of integrated switch plates, combining a doorbell with light switches in a single, elegant unit.
• Built with a robust 16A mechanism, ensuring exceptional durability and a long service life even in high-traffic areas.

Features

• Modular Component Design: A compact, self-contained momentary switch designed to be clipped into the Trinity range of yokes.
• Momentary Switch Action: The normally open mechanism is spring-loaded, making it ideal for signalling applications like door chimes and buzzers.
• Laser-Engraved Bell Icon: Features a crisp and durable bell symbol for immediate function identification, which will not rub off or fade over time.
• Heavy-Duty 16A Mechanism: Built with a high-quality 16A/250V rated switch for maximum electrical reliability and longevity.
• Secure Clip-In System: Integrated clips lock the module firmly into the yoke with a positive click, ensuring it will not become dislodged.
• Durable Polycarbonate Casing: The module body is made from high-grade, impact-resistant polycarbonate for safety and durability.
• Universal Yoke Compatibility: Designed to fit any aperture in the Trinity 4x2 and 4x4 yokes, from 1-lever to 6-lever configurations.
• Dual Colour Options: Available in classic White and modern Black Graphite to perfectly match corresponding yokes and cover plates.
• SANS 60669-1 Certified: As part of the Trinity system, it is tested and approved to meet the highest South African safety standards.

Benefits

• Complete Customization: The modular design is the key to flexibility. Place this bell press module alongside standard light switches, dimmers, or data sockets in a multi-lever yoke to create a truly bespoke control panel.
• Professional and Intuitive Finish: The engraved icon provides a premium, built-in look that is far superior to stickers or unmarked switches, ensuring visitors can easily identify the doorbell.
• Cost-Effective Repairs: If the mechanism ever wears out, you only need to replace this inexpensive module, not the entire switch plate, yoke, and frame.
• Simplified Inventory: A major advantage for electricians. Stocking individual modules like this is more efficient and versatile than stocking numerous pre-configured, dedicated bell press units.
• Rapid, Screwless Assembly: The module clips directly into the yoke without needing its own screws, significantly speeding up the final assembly of the switch plate.
• Enhanced Aesthetics: Integrate your doorbell seamlessly into your main switch panel for a cleaner, more minimalist look at your entryway, eliminating the need for a separate, often unsightly, doorbell button.

In-Depth Technical Specifications

This module is the essential building block for creating custom signalling and doorbell solutions. Below are its detailed technical specifications.

Product Specifications

Required Components for a Complete Unit

This is a module component and requires additional parts for a complete, functional installation:

• Trinity Yoke: A mounting frame that fits into the wall box (e.g., TS2011Y, TS2021Y, TS4041Y).

Ideal Use

The Trinity Bell Press Module is perfect for any application requiring a momentary electrical signal.

• Residential Doorbells: Its primary use is to activate doorbell chimes at the entrance of a house or apartment.
• Office Access Control: Ideal for use as a "buzz-in" switch at a reception desk to operate an electronic door strike or magnetic lock.
• Request-to-Exit (RTE) Buttons: Can be used on the secure side of a door in an access control system.
• Service & Assistance Calls: Perfect for creating discreet call buttons in hotel rooms, restaurants, retail changing rooms, or healthcare facilities.
• Intercom Systems: Functions as the "call" button on an apartment or gate intercom panel.
• Industrial Signalling: Can be used to trigger buzzers, horns, or lights in a factory or workshop environment.

Tips

• This is a Module Only: It is essential to understand that this product cannot be used on its own. You MUST purchase a compatible Trinity Yoke and a Trinity Cover Plate to create a functional switch.
• Momentary vs. Latching: This is a momentary switch. It is ON only when you press it. It is not a latching switch like a standard light switch (which stays ON or OFF). Do not use it for standard lighting.
• Typical Wiring: Bell press switches are most often used in low-voltage circuits. This usually involves a transformer to step the voltage down (e.g., to 8V, 12V, or 24V) to power the chime or buzzer. Always refer to the wiring instructions for your specific chime or access control system.
• Installation Sequence: For the easiest assembly, wire the conductors to the module first. Then, align the module with the desired aperture in the yoke and press firmly until it clicks securely into place.
• Removing the Module: To remove, use a small flathead screwdriver to gently press the retaining clip on the side of the yoke aperture while pushing the module out from behind.
