Carrier HK50ZT001 Sensor Module

The Carrier HK50ZT001 Sensor Module is a high-performance photoelectric duct smoke detector designed for heavy-duty commercial and industrial HVAC applications. Engineered for precision, this genuine OEM replacement part integrates seamlessly into larger air-handling systems to monitor ductwork for products of combustion. With an operational air velocity rating of 100 to 4,000 ft/min, this module ensures reliable smoke detection across a wide range of airflow conditions. It features a rugged aluminum housing that handles ambient temperatures from -20°F to 158°F, making it suitable for rooftops and mechanical rooms. The HVAC duct sensor serves as a critical safety component, providing the necessary signal to trigger system shutdown or interface with fire alarm control panels. For contractors, the Carrier HK50ZT001 offers straightforward field installation with a 4-wire RJ45 connection and includes a test magnet for quick verification of sensor response and alarm relay functionality.

• Universal Voltage Integration: Compatible with multiple power sources including 24 VAC, 120 VAC, and 240 VAC to suit various control circuits.
• Full Installation Kit: Includes necessary gaskets, exhaust tubes, and mounting hardware to ensure a proper airtight seal.
• Visual Diagnostic Indicators: Built-in LEDs provide instant status updates for Power, Alarm, Trouble, and Dirty sensor conditions.

Common Questions

Does the HK50ZT001 require a specific sampling tube?
Yes, this module is designed to work with a sampling tube (often sold separately depending on duct width) that extends into the airflow to draw air across the photoelectric sensor. Using the correct length ensures the pressure differential remains within the required 0.005 to 1.00 inches of water.

Can this sensor module be used for residential HVAC systems?
While technically possible if the duct requirements are met, the HK50ZT001 is primarily engineered for commercial HVAC maintenance and 4-wire industrial applications. It is most commonly found in Carrier 48HCFD and 50TCQD series units.

How do I perform a field test on this module?
The unit includes a test magnet that can be placed against the housing in the designated area to simulate a smoke condition, allowing the technician to verify that the internal relays trip and the HVAC system shuts down as intended.
