Intelligent Duct Smoke Detector FX-PDD

Manufacture: kidde

Product code: FX-PDD

The Kidde FX-PDD Duct Smoke Detector ⭐
✅ is designed for easy installation and represents the perfect balance of practical design and advanced technology , The FX-PDD features a unique design that speeds installation and simplifies maintenance. Removable dust filters, conformally coated circuit boards, and optional water-resistant gaskets keep contaminants away components, ensuring years of trouble-free service. When cleaning is required, the assemblies come apart easily and snap back together in seconds.

Product information

- The duct smoke detector’s primary purpose is to provide early warning of an impending fire and shut down the HVAC unit in order to prevent smoke circulating throughout the building. The duct smoke detector is designed for use in duct applications where temperatures can exceed standard detector capabilities.

Standard Features

• Less than 2" deep for easy installation and applications where space is tight

• 32 to 120 °F (0 to 50 °C) operating range with 100 ft/min. to 4,000 ft/min air velocity rating assures reliability under harsh environmental conditions

• Status LEDs remain visible through clear assembly cover

• Cover monitor switch for added security

• Standard sampling tube spacing for easy drop-in migration other detectors

• Sampling tube can be installed with or without the cover in place and can be rotated in 45-degree increments to ensure proper alignment with duct airflow

• 15.2 to 19.95 Vdc operation

• Magnet-activated test switch

• One Form C auxiliary alarm relay for controlling ancillary equipment (e.g., HVAC controls)

• No special tools required for easy access to field connections

• Environmental compensation with differential sensing for reliable, stable, and drift-free sensitivity

• Wide 0.79% to 2.46% obscuration/ft. smoke sensitivity

• Identification of dirty or defective detectors

Application

- The FX-PDD duct detector is ideally suited to duct smoke detection applications where early indication of combustion is required within the confined space of ventilation ductwork. Its primary purpose is to provide early warning of an impending fire and to prevent smoke circulating throughout the building. It is typically used to detect smoke in the supply side of the HVAC system but can provide supervision of the return side as well.

- FX-PDD detectors continually sample air flow in the HVAC duct and initiate an alarm condition whenever smoke is detected. An alarm is activated when the quantity (percent obscuration) of combustion products in that air sample exceeds the detector’s sensitivity setting.
