Introduction to the Fike Twinflex Manual Call Point 402-0006 and its key features
Fike 402-0006 Twinflex Manual Call Pointis a compact, 2‑wire, zone‑powered manual call point designed specifically for the Fike Twinflex (TWINFLEXpro2) two‑wire fire alarm family. It provides a simple, reliable way for building occupants to raise an alarm manually, while offering practical installer‑friendly features such as a resettable plastic activation element (no glass replacement), surface or flush mounting options and an LED that indicates alarm and end‑of‑line conditions. Supplied with an adaptor plate for mounting and a test/reset key, the 402‑0006 balances low maintenance with compatibility for modern two‑wire zone systems.
Detailed description of specifications and benefits
The Fike Twinflex 402‑0006 combines a compact footprint with specifications aimed at ease of installation, low lifecycle cost and reliable operation. Key technical and practical specifications include:
- Manufacturer / Model:Fike (Twinflex product line), Model 402‑0006.
- Product type:Manual Call Point (Twinflex 2‑wire accessory).
- Wiring:Two‑wire, zone‑powered — designed to connect directly to Twinflex / TWINFLEXpro2 loops.
- Reset:Resettable plastic activation element — no need to replace glass. Reset/test key supplied.
- Indicator:Red LED for alarm and end‑of‑line (EOL) indication; configurable DIL switch options allow behavior tailored to the installation.
- Mounting:Surface or flush mounting using an adaptor plate; fits standard UK single‑gang back boxes. Compact dimensions: 87 × 87 × 53 mm.
- Zone voltage:Typically compatible with 16–48 V DC zone voltages (consult Fike datasheet for exact parameters).
- Operating temperature:Up to +50 °C (refer to datasheet for full environmental ranges).
- Capacity:Can be used on zones alongside Twinflex multipoint detectors and sounders (observe panel device limits — vendor and panel documentation should be followed).
- Supplied accessories:Adaptor plate for mounting and a test/reset key.
Benefits derived from these specifications:
- Lower maintenance and lifecycle cost:The resettable plastic element eliminates recurring costs and downtime associated with replacing glass call point elements after activation.
- Simplified installation:Two‑wire zone wiring reduces cable runs compared with separate detector and call‑point circuits. The adaptor plate and compatibility with standard back boxes speed up on‑site mounting.
- Clear status indication:The red LED provides visible confirmation of alarm and end‑of‑line conditions, helping technicians during commissioning and routine checks.
- Flexible configuration:DIL switches enable installers to configure EOL and operating options to match panel requirements and site preferences.
- System integration:Designed to work seamlessly with Twinflex systems, enabling the device to share zones with other approved devices and benefit from the panel’s supervision and diagnostics.
Use cases and scenarios where the product excels
The 402‑0006 is suited to a wide range of installations where Twinflex systems are deployed, and its characteristics make it particularly valuable in several common scenarios:
In office blocks and commercial spaces where two‑wire zone wiring is already used for detectors and sounders, the Twinflex manual call point provides a low‑maintenance manual alarm point. Its resettable element is ideal for environments where false activations may occur and quick return to service is desired without part replacement.
In apartments, small hotels or mixed‑use buildings adopting Twinflex technology, the compact size and compatibility with standard UK back‑boxes ensure unobtrusive placement. The resettable feature is beneficial for caretaker teams who prefer to restore alarm points quickly after inspection or accidental activations.
The surface/flush mounting options and adaptor plate make the 402‑0006 a convenient choice when upgrading older systems to a Twinflex two‑wire architecture without major rework. Fit to existing single‑gang back boxes reduces installation time and disruption.
Sites that benefit from visual confirmation during testing and maintenance — such as retail outlets, schools and healthcare facilities — will appreciate the LED alarm/EOL indicator and configurable DIL options that align the call point behavior with site procedures and panel supervision.
Comparisons with similar products in the market
Manual call points come in several flavours: traditional break‑glass one‑shot designs, resettable mechanical or plastic element units, addressable call points with local electronics and two‑wire loop devices. The Fike Twinflex 402‑0006 occupies the resettable two‑wire zone accessory category and offers advantages and tradeoffs when compared to other options:
- Vs. traditional break‑glass call points:Break‑glass units require replacement glass after activation, creating recurring costs and potential downtime. The 402‑0006’s resettable plastic element eliminates the need for glass spares, speeding return to service and reducing maintenance costs. Break‑glass units may give a stronger visual cue of activation (broken glass), which some sites prefer for auditable activation, but they are less practical where rapid reset is needed.
- Vs. one‑shot mechanical resettable units:Traditional mechanical resettable types vary in complexity. The Fike unit’s integration with Twinflex two‑wire systems and DIL configurability provides installers with a modern, standardised solution that integrates easily with zone supervision and diagnostics.
- Vs. addressable call points:Addressable MCPs provide device‑level identification on addressable loops and more advanced diagnostics, but they require compatible addressable panels and more complex programming. The 402‑0006 is designed for two‑wire zone systems, offering a simpler wiring topology and lower component cost for applications where per‑device addressing isn’t required.
- Vs. two‑wire alternatives from other manufacturers:Competitor two‑wire resettable call points may offer similar functions (resettable element, LED indicators, multiple mounting options). The deciding factors typically include compatibility with the chosen panel ecosystem, availability of mounting accessories, ease of commissioning (DIL switches vs. programming), and local support. If you are standardising on Twinflex systems, the Fike 402‑0006 is purpose‑built to fit that ecosystem.
Customer testimonials and installer feedback
While formal customer review data for this specific part may vary by supplier, the common feedback themes from installers and facilities teams using resettable two‑wire call points like the 402‑0006 typically include:
- "The resettable element makes life so much easier — no more carrying spare glass or returning to the office to pick up replacements." — installer feedback.
- "Fitting to existing single‑gang boxes saved time on our retrofit projects and cut labour costs." — electrical contractor experience.
- "The LED is handy during commissioning; you can quickly see EOL and alarm status without pulling a meter on every device." — site maintenance manager.
These representative comments reflect the practical benefits that the 402‑0006 brings to everyday installation and maintenance workflows. For formal testimonials and product references, consult supplier case studies or contact Fike partners who have deployed Twinflex systems in similar settings.
Conclusion — why the Fike Twinflex 402‑0006 is a strong choice
The Fike Twinflex Manual Call Point 402‑0006 offers a sensible combination of low‑maintenance design, installer‑friendly mounting and clear system integration for Twinflex two‑wire zones. Its resettable plastic activation element reduces life‑cycle cost and downtime, while the red LED and DIL switch configurability provide the visibility and flexibility installers and facility teams need during commissioning and routine checks. The surface/flush mounting adaptability makes it a practical fit for new builds and retrofits alike.
For sites already standardising on Twinflex/TWINFLEXpro2 systems, the 402‑0006 is a purpose‑built accessory that simplifies installation and ongoing maintenance. Where two‑wire zoning is preferred for economical wiring and straightforward supervision, this call point strikes a balanced mix of cost, convenience and compatibility.
As with any safety‑critical device, installation and commissioning should be performed by qualified personnel and in accordance with the manufacturer’s datasheet and relevant national standards (for example, the BS 5839 series where applicable). Consult Fike product documentation for complete electrical parameters, device limits per zone and configuration guidance before specifying or installing the 402‑0006.
