DUCT SMOKE DETECTOR

True Duct Smoke Detector
The TDD True Duct Smoke Detector provides an auto or manual reset relay output on detection of smoke, with a user adjustable threshold.

An analogue output can transmit smoke and service alarms to a BEMS system.

The TDD is a single stand alone unit as an Intelligent True Duct Smoke Detector.

The TDD is purpose built for duct installations to withstand, and take account of that specific environment.

• Sensing smoke directly in the duct without help of built-in fan in the detector - no use of sampling tubes

• Automatic compensation for dust and dirt ensuring constant sensitivity -   no false alarm

• Damped or undamped output

• Analogue output for service diagnostics

• LED barograph display as option

• Simple to clean and does not need to be removed from the duct work when cleaning is required
