The SL-2000-P series duct smoke detectors provide early detection of smoke and products of combustion present in the ducts of any commercial, industrial, or residential application. These devices are designed for the prevention of smoke re-circulation by the air handling systems, fans, and blowers. The SL-2000-P is designed and built to meet all local requirements, as well as the NFPA and ICC Standards regarding duct smoke detectors. Output terminals are provided for remote accessories such as horns, strobes, remote status indicators, and test/reset key switches or pushbuttons. The SL-2000-P uses a photoelectric head. Air sampling is accomplished via two tubes that protrude into the duct. An exhaust tube with a standard length of 7" is included in the installation kit. Once the duct size is determined, a sampling tube must be ordered. Three standard sizes including a 2.5', 5', and 10' lengths can be ordered and cut to the correct size of the duct. The SL-2000-P provides two sets of 10A Form "C" alarm contacts, along with one set of 10A form "C" trouble contacts for monitoring head removal and supply voltage failure.
