The ACI/SL-2000 series duct smoke detectors will provide early detection of smoke and products of combustion present in the air moving through a duct in 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. Complete systems may be shut down in the event of smoke detection.
The ACI/SL-2000 will allow up to 30 detectors to be interconnected for some of the common functions including the use of a common test/reset function or to alarm when a single unit alarms. Up to 15 units and signaling devices may be interconnected to operate with a single alarm. The SL-2000 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 horns, strobes, remote status indicators, and test/reset key switches or pushbuttons.
The Ionization and Photoelectric detector heads are interchangeable. Air sampling is accomplished via two tubes that protrude into the duct. An exhaust tube with a standard length of 7" is supplied in the installation kit with the unit. 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 ACI/SL-2000 provides (2) sets of 10A Form "C" alarm contacts, along with (1) set of 10A form "C" trouble contacts for monitoring head removal and supply voltage failure. The green pilot and red alarm indicators provided on the front of the SM-501 signal the operating status of the device. The green pilot LED will be extinguished when the detector head is removed. A manual test/reset switch is located next to the LED indicators. All of these units come with a 2 year factory warranty. |
