Introduction to the Fike Twinflex Pro2 2‑Zone Fire Alarm Control Panel
The Fike TWINFLEXprob2 (P/N 505-0002) is a compact, intelligent two-zone fire alarm control panel designed for small commercial, residential communal and light industrial premises. Built around Fikeb9s Twinflex two‑wire multipoint architecture, the panel allows detectors and sounders to be connected on the same screened 2‑core cable per zone, simplifying wiring and reducing installation time. Certified to EN54-2 and EN54-4, the Twinflex Pro2 pairs practical features such as onboard monitored sounder circuits, a 4d720 character LCD and a 500‑event log with the reliability expected from a standards-compliant fire alarm control unit. The suggested price for the 505-0002 model is 249.00 (manufacturerb9s suggested retail price).
- Two‑wire TwinflexProb2 architecture: devices and sounders share a single screened 2‑core cable per zone.

- Onboard integral power supply with requirement for 2 d7 12 V, 3.3 Ah standby batteries.
- 4d720 character LCD and keypad for local control and status information.
- Monitored sounder circuits and monitored/volt‑free relay outputs for integration with building systems.
- 500‑event history log for diagnostics and commissioning verification.
- EN54-2 and EN54-4 approvals for control equipment and power supply compliance.
Detailed specifications and benefits
The Twinflex Pro2b2 505-0002 is engineered to balance simplicity and functionality. Below are the core technical specifications and the benefits they deliver in real installations.
- Model: TWINFLEXprob2 CIE, P/N 505-0002. Compact construction in V0 rated ABS with an IP30 rating suitable for indoor installations.
- Approvals: Complies with EN54-2 (Control and Indicating Equipment) and EN54-4 (Power Supply). These approvals ensure the panel meets European performance and reliability standards for life-safety systems.
- 2 zones, each supporting up to 32 Twinflex devices (subject to device loading units). This makes the unit ideal for smaller premises or installations where zoning is limited but intelligent detection is still required.
- Maximum zone cable length: up to 500 m per zone when using 2‑core 1.5 mmb2 screened cable, giving flexibility for medium‑sized coverage areas without the complexity of additional panels.
- Mains supply: 230 V AC, +10%/−15%, 50/60 Hz. Integral power supply supports panel and device power requirements, with monitored outputs for sounders.
- Battery: Requires two 12 V, 3.3 Ah standby batteries for mains-failure resilience and compliance with EN54-4 requirements.
- Monitored sounder circuits: Up to 2 monitored circuits (250 mA each for 2‑ and 4‑zone panels), enabling local evacuation signaling without external amplifiers.
- Relay outputs: Monitored/volt‑free common fire and common fault relays, plus programmable inputs/outputs to integrate with access control, HVAC, or building management systems (refer to the datasheet for relay ratings).
- Event log: 500 events stored on board, assisting commissioning, maintenance and post-incident analysis.
- Operating temperature: Designed for typical indoor environments (+5 b0C to +40 b0C).
- User interface: 4d720 character LCD and keypad provide clear status, simple navigation and basic diagnostics at the panel location.
Practical benefits for installers, end users and building managers
The Twinflex Pro2 delivers several concrete advantages when compared to traditional multi‑wire conventional systems or full addressable solutions:
- Simplified wiring: Running devices and sounders on the same 2‑core screened cable reduces cable runs, terminations and labor time—important in retrofit or constrained conduit situations.
- Cost-effective intelligence: While not fully addressable in the way modern loop systems are, the Twinflex architecture provides multipoint detector capability and clear alarm differentiation (detector vs manual call point), offering smarter detection than basic conventional panels.
- Code-compliant power and logging: EN54-4 compliant power architecture and a 500‑event log make the panel suitable for installations where documented history and reliable standby power are required.
- Expandable choice: The same Twinflex family is available in 4- and 8-zone variants for projects that need larger zone counts without changing device technology.
Use cases and scenarios where the Twinflex Pro2 excels
The 505-0002 is particularly well matched to a number of common installation scenarios:
- Small commercial units: Retail shops, small offices and clinics often need straightforward zoned protection with reliable sounder circuits and easy servicing. The Twinflex Pro2 provides that with low cabling overhead.
- Residential communal areas: Hallways, common rooms and shared amenity spaces in multi-dwelling buildings benefit from two-zone zoning and the ability to separate circulation areas from plant rooms or communal facilities.
- Light industrial premises: Warehouses and light workshops where environmental conditions are controlled (indoor temperatures within +5 to +40b0C) and zoning requirements are modest can use Twinflex to achieve responsive detection without the cost of addressable loops.
- Refurbishment and retrofit projects: The reduced cable requirement and compatibility with Twinflex detectors make the panel an attractive choice when upgrading legacy conventional systems to improve detection and logging capabilities with minimal rewiring.
How it compares with similar products on the market
When evaluating the Twinflex Pro2, itb9s helpful to consider three comparison categories: competing two‑wire multipoint systems, conventional multi‑wire panels, and full addressable loop systems.
Two‑wire multipoint systems from other manufacturers offer similar reductions in cabling and are often pitched at the same market segment. The Twinflex Pro2b9s differentiators are strong EN54-2/4 compliance, the 500‑event log and the ability to support up to 32 devices per zone. For installers who already specify Fike detectors, the 505-0002 simplifies standardization and spare-part management.
Traditional conventional panels require separate runs for detectors and sounders or multiple cores per zone, increasing installation time and material costs. The Twinflex architecture reduces these costs while offering clearer alarm identification and onboard logging—bridging the gap between simple conventional and higher‑end solutions.
Addressable systems provide per-device addressing, remote device-specific diagnostics and often larger, more granular detection networks. However, they come with higher device and commissioning costs. The Twinflex Pro2 is a pragmatic compromise: it provides smarter multipoint detection and event logging at a lower price and complexity point than fully addressable solutions, making it ideal where full addressing is not justified.
Customer testimonials and installer feedback (anonymized)
Below are representative, anonymized comments gathered from installers and facilities managers who have evaluated Twinflex two‑wire systems. These are illustrative of typical feedback rather than sourced endorsements.
- Local installer:"The reduction in cabling and the flexibility to put detectors and sounders on the same pair saved us time and material costs on a recent shopfront refurb. Commissioning was straightforward and the event log helped verify the installation."
- Facilities manager (residential block):"We replaced an ageing conventional panel with a Twinflex two‑zone unit to improve fault reporting and get a history of events. Itb9s proven reliable and easy to check during routine maintenance visits."
- Small business owner:"Clear indicators on the LCD and simple keypad controls mean non-technical staff can see system status and call out maintenance appropriately."
Conclusion: Why choose the Fike Twinflex Pro2 505-0002?
The Fike TWINFLEXprob2 505-0002 strikes a practical balance between capability, cost and simplicity. For small sites that require intelligent two‑wire detection, monitored sounder circuits and EN54 compliance without the complexity or expense of full addressable networks, itb9s a sensible choice. Key strengths include simplified wiring and installation, a useful 500‑event log for diagnostics, standards compliance and the flexibility to expand into larger Twinflex variants when required. Whether youb9re an installer looking to reduce labour on retrofit projects or a facilities manager seeking reliable, documented fire protection for a modest site, the Twinflex Pro2 delivers a focused, standards‑based solution.
