Laser Smoke Detector senses the earliest particles of combustion. And that provides early warning of fire. Its high sensitivity is balanced with high stability to minimise false alarms. Like an ionization detector,Laser technology gives you fast response detection in high sensitivity applications such as clean rooms, telecommunications centers or computer rooms — areas where any damage is too much.Currently there are two smoke sensing technologies
in wide use: ionization and photoelectric. Both technologies have different strengths. Ionization detectors detect fast-flaming fires well — but are not so quick with slow-smoldering fires. On the other hand, photoelectric detectors detect slow-smoldering fires well — but are not so quick with fast-flaming fires.
How It Works?
The principles of laser detection are similar to those of photoelectric technology. In a photoelectric smoke detector, an LED emits light into a sensing chamber that is designed to keep out ambient light while allowing smoke to enter. Any particles of smoke (or dust) entering the chamber will scatter the light and trigger the photodiode sensor.
Pinnacle works on the same light-scattering principle, but with 100x greater sensitivity. This ultra-sensitivity is due to
the nature of the laser itself, which is literally amplified light (the word “laser” is an acronym for “Light Amplification
by Stimulated Emission of Radiation”). Using an extremely bright, controlled laser diode, the laser beam is transmitted through the chamber to a light trap which eliminates any reflection. If a particle of smoke (or dust) enters the chamber, light from the laser is scattered and the detector, using its patented algorithms, checks the nature of the scattered light to determine whether the source is dust or smoke. If a determination of smoke is made, the alarm is signaled.
Smoke particles, especially those by-products of an early fire, are extremely small, hence the need for the high
sensitivity of the laser.
- Sensitivity-Extremely high sensitivity with superior early warning performance.
- Stability-Algorithms for proven resistance to false alarms
- Versatility-One detector can be used for detection of fast-flaming and slow-smoldering fires.
- Pinpoint accuracy-Identifies the precise location of the fire, reducing time to extinguish it.
- Lower overall cost-Reduced cost in installation and maintenance.
