Introduction to the Fike Twinflex I/O Module (802-0006) and its Key Features
The Fike Twinflex I/O Module (model 802-0006) is a compact, professionally built interface module designed to expand the capabilities of Twinflex addressable fire systems. Combining a monitored input with selectable end-of-line (EOL) supervision and two changeover (DPCO) relay outputs, this module provides a flexible way to connect ancillary equipment — such as plant shutdown circuits, door releases, ventilation controls, or auxiliary alarms — to a Twinflex zone. Supplied mounted in a standard double-gang back box for quick flush or surface installation, the unit is ideal for installers and system integrators who need a reliable, standard-compliant interface option.
- Key features include:Monitored input with selectable EOL supervision (3.3 k840; and 680 840; firing resistors).Two changeover (DPCO) relay outputs rated for mains or low-voltage loads (note: do not mix mains and low-voltage on the same unit outputs simultaneously).Onboard DIP switches to configure input/output mode, alarm behaviour and EOL settings.LED indicators to show Output Active and EOL/Input status for quick troubleshooting.EN54-18 declared performance and compatibility with Twinflex Pro and Twinflex V3 panels.
Detailed Description of Specifications and Benefits
The 802-0006 is engineered to balance compact form factor with the electrical and environmental specifications expected in professional fire detection systems. Below is a detailed, practical breakdown of its specifications and the benefits they provide.
- Model: 802-0006; product type: two-wire Twinflex I/O interface module.
- Mounting: supplied mounted in a standard double-gang back box (flush or surface) for rapid installation.
- Dimensions: 146 D7 87 D7 41 mm overall, with a back box depth of 32 mm — compact enough for most wall cavities and surface mounting locations.
- Flammability / IP: UL94-V2 / IP30, intended for indoor use in protected environments.
Benefits: the small footprint and standard back box mounting significantly reduce installation time and the need for bespoke enclosures. The UL94-V2 rating provides basic flame resistance appropriate for internal fire panel accessory hardware.
- Panel voltage: 25.5E2809335 V DC when connected to mains-powered panel; 20E2809326 V DC on battery-powered panels.
- Operating current (typical): quiescent approx. 0.207 mA, with EOL ON adding ~0.080 mA; active state typically ~22.715 mA.
- Max input cable length: 3 m (for monitored input connections).
- Relay rating: 30 V DC @ 2 A; 250 V AC (50/60 Hz) @ 2 A, with 3 A surge capacity.
- Fuses: two 3.15 A antisurge 20 mm ceramic fuses protect the outputs.
- EOL options: selectable 3.3 k840; and 680 840; firing resistors to support different peripheral devices and supervision philosophies.
- DLU / Zone loading: approximately 23 DLU (confirm exact loading with panel documentation during system design).
Benefits: low quiescent current helps preserve panel zone loading allowances and battery runtime. The selectable EOL values and onboard DIP switches let installers tailor supervision behaviour to site wiring and connected equipment. Relay ratings suit both common low-voltage control tasks and many mains switching actions (subject to correct wiring and separate isolation for high-voltage loads).
- Operating temperature range: B1E28090E280910 C2B0C to +50 C2B0C.
- Standards: EN54-18 declared performance (Declaration of Performance available).
Benefits: EN54-18 performance means the module fits into regulated installations where EN standards are required. The operating range covers the conditions typical inside plant rooms, lobbies, and other protected internal environments.
Use Cases and Scenarios Where the Module Excels
The Twinflex I/O Module (802-0006) is a versatile component that solves multiple real-world interface challenges in fire and life-safety installations. Typical use cases include:
- Plant shutdown on alarm:When a fire condition is detected, controlled shutdown of boilers, gas supplies, and other plant can be triggered via the module's relay outputs to reduce hazard and protect equipment.
- Controlled door release:Interface to electromagnetic door holders or release mechanisms to allow fire panels to command doors to close (or release) in specific alarm conditions.
- Ventilation and HVAC control:Switch fans, dampers or ventilation circuits to prevent smoke spread or to support smoke control strategies.
- Auxiliary alarm/control signalling:Drive external sirens, strobes, or relay-based control inputs on third-party equipment where monitored input and supervised behaviour are required.
- Monitoring third-party C/O contacts:The monitored input with EOL supervision enables the panel to detect open/short conditions or a trigger from an external device with supervised integrity.
Why it excels: the combination of a monitored input and two changeover relays in a small, mountable unit makes the 802-0006 a one-stop interface that reduces the number of separate components, saves wall space, and simplifies wiring and testing during commissioning.
Comparisons with Similar Products on the Market
When selecting an I/O interface module, installers commonly evaluate functionality, standards compliance, reliability, and ease of installation. The Twinflex 802-0006 stands out in these areas but it helps to understand how it compares to other options:
- Versus simple relay modules:Basic relay modules may offer only dry contacts without supervised inputs or EOL supervision. The 802-0006 adds monitored input capability and selectable EOL resistors, giving better fault detection and integration with addressable panels.
- Versus multi-relay or programmable I/O modules:High-end programmable I/O modules can offer many channels and logic functions but tend to be larger, more expensive, and require more configuration. The 802-0006 provides a focused, cost-effective solution for common tasks (two relays + one supervised input) and is simpler to commission.
- Versus proprietary modules for other panels:Compatibility matters: the 802-0006 is declared for Twinflex Pro and Twinflex V3 panels (not compatible with Twinflex SRP). If you are committed to Twinflex systems, using a module designed and declared for those panels simplifies compliance and support.
In summary, the 802-0006 offers a balanced mix of features and affordability. For low-to-medium complexity projects that need reliable supervised inputs and a couple of relay outputs, it often represents a better installer-friendly choice than either underspecified relay-only modules or overly complex expandable I/O hubs.
Customer Feedback and Installer Experience
While individual facility managers and installers will have different experiences, common feedback themes from professionals who choose supervised I/O modules like the 802-0006 include:
- "Installation was straightforward": installers appreciate the module being pre-mounted in a standard double-gang back box, which saves time on site.
- "Configuration is simple": onboard DIP switches for mode and EOL settings reduce the need to access programming menus during initial setup and troubleshooting.
- "Reliable operation": the module's low quiescent current and clear LED indicators help during commissioning and ongoing maintenance.
Note: These represent generalized installer observations typical of this class of module. For project-specific references, consult case studies or ask suppliers for installer references and documented installations.
