Multi Smoke Heat Detector
Multi Smoke Heat Detector
Modern marine and industrial environments require fire detection systems that can respond reliably to both smoke and temperature variations. In areas where fire characteristics may change rapidly, combining multiple detection principles within a single device significantly improves safety. The Marine Multi (Smoke-Heat) Detector is designed to provide dependable early fire detection by simultaneously monitoring smoke and heat conditions in harsh operational environments.
Marine Multi Smoke Heat Detector
The Marine Multi (Smoke-Heat) Detector – NE-M-40814, developed by Nero Industries, is a point-type addressable fire detector designed and manufactured in compliance with TSE EN 54-5 and TSE EN 54-7 standards. It integrates smoke and heat detection within a single compact unit, ensuring reliable fire detection across a wide range of marine and industrial applications.
The smoke detection element operates based on the optical light scattering and transmission principle, while the heat detection function uses a temperature-sensitive thermistor. This dual-technology approach allows the detector to respond accurately to both rapid and gradual fire development scenarios.
Purpose of the Marine Multi Detector
The primary purpose of the Marine Multi (Smoke-Heat) Detector is to provide early and reliable fire detection in environments where fires may present as smoke, heat, or both.
By operating smoke and heat detection in parallel, the detector ensures:
-
Early alarm generation in smoke-producing fires
-
Reliable detection in smokeless fire scenarios through heat monitoring
-
Reduced risk of delayed response in critical areas
This makes the detector suitable for safety-critical marine and industrial installations.
Where to Use
The Marine Multi (Smoke-Heat) Detector is designed for use in:
-
Marine environments and vessels
-
Industrial facilities
-
General fire detection systems
-
Areas exposed to humidity, corrosion, and harsh environmental conditions
Its durable construction ensures long-term stability and reliable performance in demanding applications.
Detection Principle and Operation
The detector communicates digitally with the fire alarm control panel through an addressable interface. During normal operation, it consumes less than 7 mA, ensuring low power demand.
Once activated, the detector remains in alarm state until a reset command is issued from the fire alarm control panel. Visual status indication is provided via dual red LEDs:
-
Flashing periodically in standby mode
-
Steady illumination during alarm condition
The detector is designed for A1-class heat response according to EN 54-5, enabling detection even when smoke is not present.

What Does the Marine Multi Detector Do?
The Marine Multi (Smoke-Heat) Detector continuously monitors its environment for signs of fire by detecting both smoke particles and temperature changes. When either or both fire indicators exceed predefined thresholds, the detector triggers an alarm signal to the control panel, enabling rapid intervention and enhanced safety.
