TNA TX7100 OPTICAL SMOKE HEAD FOR ADDRESSABLE FIRE ALARM SYSTEMS

Description

The TX7100 is an intelligent, addressable optical smoke detector designed for use in intelligent fire-alarm systems. It utilises a built-in micro-processor to analyse smoke signatures in real time and perform drift compensation automatically, ensuring reliable performance over time. 

The detector complies with the European standard EN54‑7 (2000 +A1:2002 +A2:2006) and is approved by the LPCB. It supports digital addressing (1-254) on an addressable loop and is compatible with the TX7004 intelligent fire-alarm control panels from the same manufacturer. 

Key Features

• EN54-7:2000 +A1:2002 +A2:2006 certified — CE/CPR & LPCB approved for optical smoke detection. 

• Wide voltage range: 24 V DC (16 V to 28 V) supply for loop compatibility.

• Low standby current (0.6 mA) / Alarm current (4 mA) — minimal load on addressable loop circuits. 

• Addressable range 1–254 using T&A protocol — flexible network configuration. 

• Smart linear drift compensation — maintains sensitivity by compensating for chamber contamination over time. 

• 360° visual LED indicator — full-circle status LED for easy visibility. 

• Removable sensing chamber — simplifies cleaning and reduces false alarms from dust/insects. 

• Memory capacity up to 10 events — supports forensic logging / diagnostics.
