SS-L

SS-L Laser Smoke Detector Description The Gamewell SmartScanTM SS-L Laser Detector provides a revolutionary advance in early warning smoke detection technology. The unique design of this detector, combined with enhanced algorithms in the Gamewell — control panels, allows smoke detection sensitivity that is 10 to 50 times higher than present photoelectric technology. Because of this high sensitivity, the SS-L can provide very early warning of slow smoldering fires. Its performance is comparable to present aspiration technology, at a substantially lower installed cost. 6714recs.jpg Features • Advanced laser light source and patented optical design. • Sleek low-profile housing (1.66"/ 42.164 mm height). • Sensitivity to 0.03%/foot. • Rotary DECADE address switches.

The SS-L uses an extremely bright laser diode, combined with special lens and mirror optics ( U.S. SS-L with SS-B6 base (top), B501 base (middle), patent pending), to achieve and RMK400 recessed mounting kit (bottom). a signal-to-noise ratio that is much higher than traditional photoelectric sensors. In addition, the tightly focused light beam, combined with algorithms, allow the system to differentiate between dust and smoke particles. Because of this differentiation, the SS-L can be set to extremely high sensitivity, yet can reject false signals caused by larger airborne particles such as dust, lint, and small insects (U.S. patents pending). Installation The SS-L plug-in detector uses a separate base to simplify installation, service, and maintenance. A special tool allows maintenance personnel to plug-in and remove detectors without using a ladder. Mount base on a box which is at least 1.5" (38.1 mm) deep. Suitable mounting base boxes include: • 4" (101.6 mm) square box. • 3-1/2" (88.9 mm) or 4" (101.6 mm) octagonal box. • Single-gang box (except relay or isolator base).

Wiring Diagram (standard base) SS-L Design The SS-L incorporates an extremely bright laser diode and integral lens that focuses the light beam to a very small volume near the receiving photo sensor. The light then passes into a light trap and is absorbed. The photo sensor is activated by a scattering of smoke particles in this small-volume light beam. In a typical photoelectric detector, the light beam is very wide and can reflect off the chamber walls into the photo sensor because dust accumulation changes the wall color from flat black to gray. With the SS-L, the concentrated light beam does not touch the walls, therefore it is much less susceptible to dust accumulation. Smoke scatters light in all directions and, in a typical photoelectric detector, only a small portion of that scattered light reaches the photo sensor itself. In the SS-L, a special mirror reflects and concentrates most of the scattered light into the photo sensor. See laser detail drawings on following page. Compared to smoke, airborne dust particles are very large and very sparse. Since a) they are in motion; b) the illuminated volume is very small; and c) the SS-L flashes the laser only every few seconds; then the occasional dust particle cannot remain in the light volume for more than one or two samples. This transient signal from dust is the key to the dust discrimination.
