The Honeywell Sensepoint Plus, Sensepoint Pro, Series 3000 XPIS, and Sensepoint XCD Duct Mounting Kit is designed for the installation of gas detectors in duct systems. This kit facilitates the detection of flammable gases, carbon monoxide, hydrogen sulphide, and hydrogen within ducts, providing a crucial safety measure in environments where these gases may accumulate. The kit is supplied pre-assembled with a sample part-duct, allowing users to familiarize themselves with the components and assembly process before installation in a target duct.
Function Description:
The primary function of this kit is to enable the secure and effective mounting of compatible gas detectors within square or rectangular cross-section ducts. By positioning the detector directly within the duct, the system can continuously monitor the air flowing through for the presence of specific hazardous gases. The design ensures that the detector's sensor is exposed to the duct's airflow, allowing for timely detection and response to gas leaks or accumulations. The kit is specifically tailored for applications where interior access to the duct is not feasible, allowing for installation from the exterior only.
Important Technical Specifications:
- Compatibility: Designed for use with Sensepoint Plus, Sensepoint Pro, Series 3000 XPIS, and Sensepoint XCD gas detectors. Specific part numbers for the kit vary based on the detector model (e.g., 'SPPPDM' for Sensepoint Plus/Pro, 'S3KDMK' for Series 3000 XPIS, 'SPXCDDMK' for Sensepoint XCD).
- Duct Type: Suitable for square or rectangular cross-section ducts.
- Duct Wall Thickness: Maximum duct wall thickness of 1 mm (0.04 inches). This specification is critical for ensuring proper fit and secure mounting of the kit components.
- Calibration Flow Rate: A gas detector calibrated at 0.3 l/m in static air will read high at elevated flow rates in duct applications. This is a "fail-safe" effect, making the detector more sensitive under these conditions. For "bump" test purposes, an elevated flow rate of 5 l/m should be used when air flow in the duct exceeds 1500 ft/min.
- Hole Requirements: Installation requires drilling a 100 mm diameter hole and four 10 mm equidistant holes in the target duct wall. The provided part-duct can serve as a template for these holes.
- Link Pipe: A 5 mm ID link pipe is used to connect the sensor retainer port to the gas inlet port on the underside of the mounting plate.
- Securing Mechanisms: The kit utilizes knurled nuts to secure the gasket retaining plate to the plate fixings, and four M6 hex head screws to firmly secure the detector mounting plate to the duct assembly.
Usage Features:
- Exterior-Only Installation: The installation procedure is specifically designed for scenarios where interior access to the duct is not possible, allowing all components to be assembled and mounted from the exterior. This simplifies installation in many industrial and commercial settings.
- Template Use: The sample part-duct included in the kit can be used as a template for drilling the necessary holes in the target duct, ensuring accurate placement and fit.
- Component Assembly: The kit involves three main assembly parts: assembling duct components, assembling detector components, and mounting the detector assembly to the duct assembly. This modular approach streamlines the installation process.
- "Bump" Test Port: The external inlet to the duct-mounted unit can be used for "bump" tests, providing a quick way to verify the unit's functionality and reactivity to gas without disassembling the unit.
- Calibration Flexibility: Detectors can be calibrated in "still" air at 0.3 l/m either via the duct mounting kit inlet (in situ) or by removing the unit from the duct and using a calibration cup. This flexibility allows users to choose the most convenient method for their specific setup.
- Clear Component Identification: The installation guide provides detailed diagrams and numbered components, making it easy to identify and correctly assemble each part of the kit.
Maintenance Features:
- Calibration Procedures: The manual refers to specific detector manuals (SPPLMAN, SPPRMAN, S3KMAN, SPXCDHMANEN) for detailed calibration procedures. Regular calibration is essential to maintain the accuracy and reliability of the gas detection system.
- Component Removal for Maintenance: The design allows for the detector unit to be removed from the duct for calibration or maintenance, if preferred, by detaching it from the mounting plate.
- Sensor Retainer: The sensor retainer is a key component that holds the sensor in place and connects it to the gas inlet. Its design facilitates secure attachment and potential removal for sensor-related maintenance.
- External Gas Inlet Port: The external gas inlet port on the top of the mounting plate can be capped off when not in use, protecting it from environmental contaminants. This port is useful for maintenance activities such as "bump" testing or calibration.
- Documentation Reference: The installation guide emphasizes referring to the respective detector manuals for electrical installation, operating, and maintenance instructions, ensuring that users have access to comprehensive information for long-term care of the system.
- Pre-assembled Kit: The kit comes pre-assembled, which helps in understanding the final configuration and simplifies the initial setup, potentially reducing errors during installation and subsequent maintenance.
