Fike TWINFLEX Hatari 2-Wire Zone Sounder, Selectable Tones, High Output, 302-0001 / 302-0002

Introduction to the Fike TWINFLEX Hatari 2‑Wire Zone Sounder

The Fike TWINFLEX Hatari (part codes 302-0001 red / 302-0002 white) is a purpose-built, zone‑powered fire alarm sounder designed for TWINFLEX two‑wire systems (V3, Pro and Pro²). Compact and straightforward to install, the Hatari delivers selectable tones and volume modes, a high‑output option for extra audibility, and a bayonet locking design to reduce tampering. With documented sound output of 90+ dB(A) at 1 m (and references to up to 100 dB(A) in some modes/listings), it is intended for internal building installations where reliable life‑safety notification is required.

• System compatibility:Designed for TWINFLEX 2‑wire panels (V3 / Pro / Pro²).
• Selectable tones and volume:DIP switches provide multiple tone/pattern choices, EOL selection and high/low output settings.
• High audible output:Documented 90+ dB(A) @ 1 m (Dual Tone), with some references up to 100 dB(A).
• Low current draw:Zone‑powered with low quiescent and alarm currents for efficient panel loading.
• Robust installation:Bayonet fit with locking front, fixed wiring base and optional deep base; anti‑tamper removal requires a tool.
• Compliance reference:Declared performance references indicate EN54‑3 compatibility — confirm with the model datasheet for installation requirements.

Detailed description: specifications and benefits

The Hatari sounder is compact but engineered to meet the practical needs of installers, system designers and building owners. Below is a breakdown of the most relevant specifications and the benefits they deliver in real installations.

• Product name / Part codes:TWINFLEX Hatari standalone sounder — 302-0001 (red), 302-0002 (white).
• Diameter:Approximately 104–105 mm, making it unobtrusive on ceilings or walls.
• Depth / Height:Documented as 72 mm or 80 mm depending on datasheet and base option; a deep base is available for additional wiring space.

• Voltage range:Typically operates from 25.5–35 V DC supplied by the TWINFLEX zone output.
• Quiescent current:Very low, typically in the range of ≈92–144 µA — this conserves panel resources when devices are idle.
• Alarm current:Mode dependent — documented high alarm current typically ≈10–11 mA, low ≈3 mA.
• Loading:Hatari typically counts as ≈6.0 SLU (36 DLU) for panel loading calculations; check your panel documentation as maximums vary by system.

• Output level:90+ dB(A) @ 1 m in dual‑tone mode; some modes/listings reference up to 100 dB(A) — use the high output option where additional audibility is necessary.
• Tones & patterns:Multiple selectable patterns via DIP switches allow installers to match local code and site requirements and to provide different signalling where needed (evacuation, alert or other tones where permitted).

• Mounting:Quick bayonet fit with a locking front and fixed wiring base for secure and rapid installation. Deep base option available to simplify wiring on crowded junctions.
• Anti‑tamper:Bayonet locking requires a tool for removal, helping prevent accidental or malicious removal of the device.
• Indoor use:Intended for internal building installation as part of a life‑safety system; confirm IP rating & environmental suitability from the datasheet for your setting.

• Operating temperature:Datasheets show different ranges (−10 °C to +50 °C or −25 °C to +75 °C) — confirm the exact range for the chosen part code.
• IP / enclosure:One document lists IP21C but other Twinflex devices show IP33C or IP65 in different variants — verify the correct IP rating for your site and model.
• Standards:Declared performance references indicate EN54‑3 compatibility. Installation must follow local regulations and standards such as BS 5839 where applicable.

Economic note:The Hatari offers an affordable, high‑output option for zone‑powered systems — a pragmatic choice for budget‑conscious projects that still require reliable audibility and functionality.

Use cases and scenarios where the Hatari excels

The Hatari sounder is designed specifically for TWINFLEX two‑wire systems, and its strengths align with several common installation scenarios:

• Small to medium commercial premises:Offices, retail spaces, small warehouses and community buildings benefit from a compact, cost‑effective sounder that provides strong audibility without complex wiring.
• Refurbishment and retrofit projects:Low quiescent current and zone‑powered operation reduce the need for new power runs, easing retrofit of existing TWINFLEX systems or upgrades.
• Areas requiring tamper resistance:Schools, public facilities and communal areas gain from the bayonet locking anti‑tamper design to deter removal.
• Locations needing flexible signalling:Selectable tones and volume modes make it suitable where different alarm patterns or EOL options are required by policy or local code.
• Environments where extra audibility is necessary:Use the high output mode where the environment has higher ambient noise or where detection devices are not present in every space.

Comparisons with similar products on the market

When compared with other zone‑powered two‑wire sounders, the Hatari stands out for a few reasons, but also shares common trade‑offs with its peers:

• Compared with basic two‑wire sounders:The Hatari offers higher maximum output (90–100 dB(A)) and more selectable tones than many very low‑cost alternatives, making it a better option where audibility and flexibility matter.
• Compared with dedicated loop sounders on analogue addressable systems:Addressable sounders typically offer advanced monitoring, diagnostics and per‑device control, which the Hatari (as a two‑wire zone device) does not. However, the Hatari is simpler, less costly and easier to load on a conventional zone output.
• Compared with other TWINFLEX‑compatible sounders:The Hatari's bayonet anti‑tamper locking and selectable high output mode give it an edge in installations that prioritise security and audibility. Always check panel loading figures—some alternative devices may have lower SLU loading or different current requirements that affect system capacity.
• Durability and environmental suitability:Some competing models offer higher IP ratings or wider declared temperature ranges. Because Hatari datasheets vary, verify the exact environmental spec for the model you intend to use.

Conclusion: why choose the Fike TWINFLEX Hatari?

The TWINFLEX Hatari 2‑wire sounder is a practical, value‑focused choice for installers and specifiers working with TWINFLEX zone systems. It balances compact design with strong audible output, selectable tones and useful anti‑tamper features. Its low quiescent current and modest alarm draw make it efficient for panel loading on two‑wire zones, and the bayonet locking base speeds installation while improving security.

Before final selection, confirm the exact datasheet for the chosen part code (302‑0001 red / 302‑0002 white) to verify operating temperature, IP rating and declared performance for your installation. Ensure the installation and commissioning are carried out by a competent person and conform to the relevant local standards (for example BS 5839 in the UK) and any EN54‑3 declared performance documentation.
