TNA TX7110 INTELLIGENT ADDRESSABLE HEAT DETECTOR

Description

The TNA TX7110 is an intelligent addressable heat detector utilising both fixed-temperature and rate-of-rise sensing, ideal for environments where smoke detectors may not be reliable such as dusty or smoky areas. 
It features a microprocessor for signal analysis, onboard event memory, self-diagnostic capability and 360° visual indicator. The detector is rated to EN 54-5:2000 + A1:2002 and is LPCB approved. 
Suitable for intelligent fire alarm loops, it supports digital addressing (1–254) and is compatible with TNA’s addressable systems. 

Key Features

• EN 54-5:2000 + A1:2002 certified and LPCB approved. 

• Dual heat sensing mechanism (fixed-temperature + rate-of-rise) for optimized detection. 

• Digital addressing: 1 to 254 (TNA protocol) for easy loop integration. 

• Standby current ~0.6 mA, alarm current ~4 mA (24 V DC nominal). 

• Input voltage: 24 V DC (range 16 V to 28 V) for flexible supply. 

• 360° visual LED indicator for clear status visibility. 

• Ancillary remote indicator output for external LED/signalling.

• Operating temperature: -10 °C to +50 °C, humidity up to 95 % RH (non-condensing).

Industrial Uses / Applications

• Dusty or smoky environments where smoke detection is unreliable (warehouses, workshops)

• Areas requiring temperature-based fire detection (mechanical rooms, kitchens)

• Intelligent fire alarm loops in commercial or industrial buildings
