Product description
Detectomat Micra 25 is a laser aspirating smoke detector designed for early fire detection in sensitive or heavily contaminated environments. Smart adaptation to environmental conditions and dust separation technology help ensure reliable detection under changing conditions.
Key features
- Automatically adapts to environmental conditions using smart learning modes.
- Laser sensor technology and a smart algorithm support detection in challenging environments and adjustment of the alarm threshold.
- Helps prevent unwanted alarms caused by dust using the patented Dual Technology LDD 3D3 system.
- Automatic day/night mode adapts to environmental conditions at different times.
- The fast learning function automatically configures the system.
- Includes technology and an integrated dust filter to reduce the effects of dust and contamination.
- Connects to Loop 3000 via an IOM.
- Supports network connectivity for up to 127 participants via the RS 485 interface.
- Requires an external power supply; mounting base and recirculation pipe connection flange included.
