Fire Alarm System Addressable Fire Alarm System Addressable Detectors

Secutron's low profile addressable plug-in smoke and heat detectors with integral communications provide features that surpass conventional detectors.

Smoke Detectors

Photoelectric Smoke Detector

Provides a unique optical sensing chamber that senses smoke produced by a wide range of combustion sources.

Combined Smoke/Heat Detector

Adds dual electronic thermistors to the photoelectric detector to provide 135°F (57°C) fixed temperature thermal sensing.

Laser Type Smoke Detector

Intelligent, laser-based photoelectric smoke detector featuring extensive on-board signal processing capabilities designed to improve smoke response.

Duct Smoke Detector

The InnovairFlex DNR intelligent non-relay photoelectric duct smoke detector and DNRW watertight non-relay photoelectric duct smoke detector feature a pivoting housing that fits both square and rectangular footprints capable of mounting to a round or rectangular duct.

Heat Detectors

Fixed Temperature Heat Detector

Uses an innovative thermistor sensing circuit to produce 135°F fixed temperature detection in a low profile package

Fixed Hi Temperature Heat Detector

Provides 190°F (88°C) fixed temperature detection for high temperature applications.

Fixed + Rate-of-Rise Heat Detector

Provides both 135°F fixed and rate-of-rise thermal detection. These thermal detectors provide cost effective, intelligent property protection in a variety of applications.

Multi-Criteria Detector

Intelligent Multi-Criteria Sensor


  • CO results from incomplete combustion
  • Smoke particles by photo sensors
  • Temperature and rate of rise (ROR) via thermal measurements
  • Ambient light levels and flame signatures via IR readings
