Wisualarm products offer superior safety with Split-Spectrum Sensor Technology

Madison Express distributes a complete range of Wisualarm products, including high quality smoke alarms by Dahua, featuring Split-Spectrum Technology. This technology was created to produce a higher quality product, with fewer false alarms. It works by using two LED’s instead of one, as well as the Photocell catcher sensor. The system can differentiate between vapor, dust and smoke particles, which can therefore reduce the nuisance, stress and distraction of an alarm sounding unnecessarily.

What is Split-Spectrum Technology?

The internal chamber in every smoke alarm has an LED (Light Emitting Diode) and a Photocell catcher. Photocell catcher is a sensor which measures the amount of particles entering the chamber. When the catcher senses a quantity of particles reaching above a critical measure, the alarm will turn on the warning siren and a warning light. These particles may not be smoke. The sensor can mistake dust or steam for smoke, which can cause a false alarm.

Major benefit of Split-Spectrum Technology in Wisualarm smoke alarm products, is it’s ability to differentiate between smoke, vapor and dust, achieving a high degree of accuracy to minimise false alarms. Split Spectrum Technology works by using a red as well as a blue LED and a Photocell catcher sensor. By combining the data of particles detected under both LED’s, the system can differentiate between vapor, dust and smoke particles, reducing the number of false alarms, therefore reducing the nuisance and stress of an unnecessary scare.
