Micra25 aspirating smoke detector

Micra25 aspirating smoke detector

Laser smoke detector is used to detect fire quickly in the first moments and in sensitive and valuable places such as server rooms, clean rooms, control and monitoring centers, archiving important documents or places where the fire is growing fast. Relying on point detectors in these places can cause irreparable damage.

In these systems, the main panel sucks and samples the air inside the room 24 hours a day with its internal fan, and the pipes that are connected to it, and then it is analyzed by ultra-sensitive laser detectors. If smoke particles are detected. In the air of the room, the panel informs the relevant authorities

The laser technology embedded in this equipment is able to distinguish between smoke and annoying particles such as dust. This feature greatly reduces the number of false alarms and also enables real fire alarms as quickly as possible. A feature that makes this system suitable for very sensitive applications

Laser smoke suction detectors are about 100 times more sensitive than spot detectors, and these detectors can detect smoke before it can be seen by the human eye.

Kidde AirSense UK is one of the most well-known manufacturers of laser smoke suction detectors

The equipment of this company is supplied with the approval of the British laboratory
