PL-DSDP / DSD-P 1430009 Conventional Photoelectric use with SLR-24DH
The POTTER ELECTRIC DSD Series duct smoke detector provides early detection of smoke and products of combustion present in air moving through HVAC ducts in Commercial, Industrial and Residential applications. The DSD is designed to prevent the recirculation of smoke in areas by the air handling systems, fans and blowers. Complete systems may be shut down in the event of smoke detection. The POTTER ELECTRIC DSD-I and the DSDP operate on 115 VAC, 24 VAC and 24 VDC.
The DSD Series is designed and built to meet all local requirements, as well as the NFPA regulations regarding duct smoke detectors. Output terminals are provided for remote accessories such as a horn, strobe, remote status indicators and reset key switches or push buttons.
Air sampling is accomplished by two tubes which protrude into the duct. An exhaust tube of one standard length (7.5") is supplied in the installation kit with the smoke duct unit. Once the duct width has been determined the air intake sampling tubes must be ordered. Sampling tubes are supplied in three standard lengths 2.5 ft., 5 ft. and 10 ft. and cut to size to fit the duct. Mounting the duct smoke unit is accomplished by the use of a template and 4 sheet metal screws, which are provided. Mounting can be achieved without the removal of the clear cover which is secured by 4 capture screws.
The compact DSD contains 3 sets of alarm contacts, 1 set of form C contacts rated at 10 amps, 1 set of form A contacts rated at 10 amps, 1 set of form A contacts rated at 1 amp. There is also 1 set of form C 10 amp trouble contacts for monitoring detector head removal, and the failure of the input supply voltage.
The pilot and alarm visual indicators provided on the front of the DSD duct unit, signal the operating status of the device. A manual test/reset switch is located along side the visual indicators. This switch can be defeated by cutting a jumper on the PCB.
