Kele SL-2000 Series Quick Start Manual

DESCRIPTION
The SL-2000 Series Duct Smoke Detectors provide
early detection of smoke and combustion products pre-
sent in air moving through HVAC ducts. Air sampling is
accomplished by intake sampling tubes, which are
ordered separately. A standard length exhaust tube is
provided with each detector. These devices are 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.
OPERATION
The SL-2000 Series is designed to operate in duct
widths from 12.0" to 10.0' (30.5 cm to 3.05m) with an air
velocity from 100-4000 fpm (0.5-20.3 mps). The
SL-2000 Series will operate on any one of four input
voltages: 24 VAC, 24 VDC, 115 VAC, or 230 VAC. It
uses either a photoelectric or ionization smoke detector
head. Each detector contains two Form C and one Form
A alarm contact, which transfer in the event of smoke.
There is also one trouble contact, which supervises the
presence of input power and removal of the detector
head. A manual test/reset switch and visual indicators of
pilot and alarm are provided on the front of the detector.
Up to 30 SL-2000 Series units may be wired to use a
common test/reset function and to alarm simultaneously
when a single unit alarms.
