Pinnacle features a patented smoke sensing chamber, designed
to amplify signals from smoke but diminish stray internal reflections.
By using a laser diode instead of a standard LED light source into the
sensing chamber, Pinnacle is able to achieve sensitivities from 0.02
percent-per-foot to 2 percent-per-foot obscuration.
The detectors’ extensive software processing includes multi-alert drift
compensation, internal self diagnostics, and superior transient signal
rejection algorithms to produce unprecedented stability at ultra high
sensitivities over the complete temperature range.
Because Pinnacle is base-compatible with all other 200 Series
detectors, system designers can seamlessly mix it with other
standard detection technologies thereby reducing overall cost.
Unlike other high-sensitivity detectors, Pinnacle:
• Can pinpoint identification of the fire location through addressability.
• Experiences no delay in response time due to smoke dilution or
smoke transportation time (as in aspirated systems).
• Offers complete supervision of wiring and detector.
Pinnacle is designed to protect valuable assets and operations where
systems must remain online at all times. Many sensitive areas cannot
tolerate even small amounts of smoke. Some ideal applications for
Pinnacle include:
• Telecommunications switching facilities
• Cellular telephone infrastructure
• Integrated circuit fabrication facilities
• Computer rooms
• Traffic control centers
• Clean rooms
