Description
Secutron's low profile addressable plug-in smoke and heat detectors with integral communications provide features that surpass conventional detectors. Sensitivity is continuously monitored and reported to the pane  where the desired detector sensitivity can be programmed. Point ID capability allows each detector’s address to be set with decade address switches, providing exact detector locations for selective maintenance when chamber contamination reaches an unacceptable level.

Model MRI-2251B photoelectric smoke detector provides a unique optical sensing chamber that senses smoke produced by a wide range of combustion
sources.

Model MRI-2251TB adds dual electronic thermistors to the MRI-2251B to provide 135°F (57°C) fixed temperature thermal sensing.

Model MRI-2251TMB is a multi-criteria photoelectric smoke detector with supplementary 135°F thermal sensing. It uses advanced on-board software to combine the signals from the photoelectric and thermal elements. This software creates a multicriteria detector capable of rejecting nuisance sources but still responding quickly to real fires. Additionally, this model also adjusts its sensitivity according to the local installed environment.

Model MRI-1251B ionization detector incorporates a unique single source, dual chamber design to respond quickly and dependably to a broad range of fires.

Model MRI-5251B uses an innovative thermistor sensing circuit to produce 135°F fixed temperature detection in a low profile package. These thermal
detectors provide cost effective, intelligent property protection in a variety of applications.

Model MRI-5251RB 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.

Model MRI-5251H provides 190°F (88°C) fixed temperature detection for high temperature applications
