The TXC7130 is a conventional single-ended reflective beam smoke detector designed for wide-area protection in large interior spaces. It integrates both transmitter and receiver in one housing and uses a reflector panel to return the IR beam. The device is certified to standard EN 54-12 by LPCB. It features a built-in laser pointer for alignment, a digital display for beam strength monitoring, and selectable sensitivity ranges (for example 2.6 dB, 3.8 dB or 5.8 dB) and beam path spans from 8 m up to 100 m. It is especially suited to high-ceiling or open spaces like warehouses, exhibition halls, hotels, large storage areas, where conventional point detectors are less effective. Key Features: Single-ended reflective beam infrared detection for wide-area coverage (8–100 m span); Four selectable beam path ranges: 8-20 m, 20-40 m, 40-70 m, 70-100 m via encoder or DIP switches; Three sensitivity levels: 2.6 dB (high), 3.8 dB (medium), 5.8 dB (low) for tailored performance in specific conditions; Built-in laser pointer and digital guide display for easy alignment and setup; Auto-compensation algorithm: monitors and adjusts for contamination, aging of transmitter/receiver, movement, dust, to maintain sensitivity over time; Fire and fault relay outputs (e.g., NO/NC contacts, rated for ~2 A @ 30 V DC); Operating voltage: 20 – 28 V DC; typical current consumption: standby ~23 mA, alarm ~33 mA, commissioning ~56 mA; Certified to EN 54-12:2015 standard with LPCB certificate (Ref: 1330a-(cl-8)). Industrial Uses / Applications: Warehouses, high-bay storage areas; Exhibition halls, large open-plan retail spaces; Museums, hotel lobbies, leisure centres; Areas with high ceilings or difficult access for point detectors.
