Product Overview

The 511C is a white conventional photoelectric direct-wire Smoke Detector with drift compensation and features a low profile and self-diagnostics. The 500 series two-wire detector meets NFPA 72 field sensitivity requirements without the need for external meters. It continually monitors its own sensitivity and operational status and provides a visual indication if it drifts out of the sensitivity range or fails internal diagnostics. Drift compensation allows the detector to automatically adjust its sensitivity over time as it becomes dirty, increasing the time between cleaning and the life of the detector. The patented field replaceable optical chamber simplifies cleaning. Normal sensing occurs every 9 seconds. This rate doubles when a signal exceeding the alarm threshold value is sensed. Two additional successive signals above the threshold level will initiate an alarm.
  • Built-in drift compensation
  • Field-replaceable optical chamber
  • Small, low-profile design
  • 18 to 12AWG Field wire size
