Overview
The Fike TWINFLEXpro² 505-0002 is an intelligent two‑wire fire alarm control panel (2‑zone) engineered for use with Fike Twinflex multipoint detectors and compatible Twinflex devices. It supports mixed device and sounder wiring on a single screened 2‑core cable per zone and includes an integral power supply and comprehensive event logging.

• Two‑wire TwinflexPro² architecture—devices and sounders on the same pair of wires.
• 2 zones (505-0002 model); other variants available in 4 and 8 zones.
• Up to 32 devices per zone (subject to device loading units).
• Distinguishes detector alarms (smoke/heat) from manual call point activations; checkpoint (alarm confirmation) functionality for dwelling/communal zoning.
• 4×20 character LCD and keypad; 500‑event log for history and diagnostics.
• Onboard monitored sounder circuits and monitored/volt‑free relay outputs; programmable inputs/outputs for peripheral integration.
• Complies with EN54‑2 and EN54‑4 (see Fike datasheet for full approvals and compliance details).

Typical uses
Ideal for small commercial, residential communal areas and light industrial premises where a cost‑effective two‑zone intelligent two‑wire system is required. Suitable for installers and contractors seeking a conventional/non‑addressable two‑wire solution using Fike Twinflex detectors.

Installation & safety
Requires two 12 V, 3.3 Ah standby batteries. Install, configure and commission only by a competent person in accordance with the official Fike installation manual and local regulations (eg BS 5839 where applicable). Refer to the Fike datasheet for terminal wiring, zone cable requirements and full electrical ratings.
