Overview
The Fike TwinflexPro2 (505‑0004) is a compact, intelligent 2‑wire (Twinflex) 4‑zone fire alarm control panel designed for smaller commercial and residential installations. It supports a single screened 2‑core per zone for both detection and sounder circuits, reducing cable runs and installation cost.

• 4 onboard zones; supports up to 32 Twinflex devices per zone.
• Automatically distinguishes detector alarms (smoke/heat) from manual call‑point activations.
• 4×20 character LCD and keypad for local configuration and status indication.
• 500‑event log, programmable day/night modes, alarm confirmation and delay programming.
• Two monitored configurable sounder outputs, volt‑free fire and fault relays and monitored inputs.
• RS‑485 communications for up to 8 repeater panels.
• Integral EN54‑compliant power supply; requires 2 × 12V 3.2Ah batteries for standard standby (optional larger battery enclosures available).

Why choose this panel?
The Twinflex two‑wire architecture reduces installation time and materials by allowing detection and alarm circuits on a single screened 2‑core per zone. The panel is suited to small commercial sites, shops, offices and multi‑occupancy residential installations where a compact, standards‑referenced conventional panel is required.

Compliance & installation
Fike documentation references EN54 and CPR standards — consult the supplied datasheet/Declaration of Performance for full certification details. Installation, configuration and testing should be carried out by a competent fire alarm engineer in accordance with applicable UK standards (eg BS 5839 series) and local regulations.

Safety & battery
The unit requires two 12V 3.2Ah standby batteries (not supplied) for typical 72‑hour standby. For extended standby or larger systems, use the optional external battery enclosure. Ensure batteries are connected per the manufacturer instructions and replaced as recommended.
