Air Products & Controls SL-2000P Photoelectric Duct Smoke Detector X13790908010 with 3-Wire Harness for HVAC Smoke Detection Systems

Air Products & Controls SL-2000P Photoelectric Duct Smoke Detector X13790908010

Condition: Appears used; shows prior handling/use and should be treated as a previously installed surplus unit. Includes smoke detector assembly and 3-wire harness as shown. Mounting hardware, sampling tube, exhaust tube, remote accessories, and any additional installation parts are not included unless pictured.

This Air Products & Controls SL-2000P is a photoelectric duct smoke detector intended for early detection of smoke and combustion products moving through HVAC duct systems. The SL-2000-P is part of the SL-2000 Series and is identified by the manufacturer as a 4-wire, universal-voltage photoelectric duct detector used in commercial, industrial, and residential HVAC applications. The series is designed for use in supply and/or return ducts and is commonly applied to shut down fans, signal alarms, or interface with building automation and fire/life-safety systems when smoke is detected.

Detailed Description

This listing is for a used Air Products & Controls SL-2000P duct smoke detector, marked X13790908010, with an included 3-wire harness. The SL-2000 Series uses a photoelectric sensing method in this “P” version and is designed to monitor air moving through HVAC ducts rather than open-area room conditions. Manufacturer documentation describes the series as suitable for air velocities from 100 to 4,000 feet per minute, and notes installer-friendly features such as tool-less testing with the cover in place and simplified maintenance access.

The SL-2000 family is described in product literature as a universal-voltage duct detector with support for 24 VAC/VDC or 115/230 VAC operation, depending on configuration and wiring. Product references also describe relay outputs and remote accessory support for items such as horns, strobes, remote indicators, and test/reset controls. Because this unit is used surplus and only the pictured harness is included, buyers should verify voltage requirements, accessory compatibility, sensor head condition, and completeness before installation.
