Aspirating Smoke Detection | Ultra-Sensitive Smoke Detection System VESDA
VESDA
Detects smoke at ultra-early stages with 10,000 times the sensitivity of a conventional smoke detector.
The ultra-sensitive smoke detection system "VESDA" detects extremely small amounts of smoke particles by analyzing air drawn from pipes through aspirating smoke detection (ASD), allowing for the very early detection of fire incidents. It boasts an ultra-high sensitivity that is 10,000 times greater than the operational concentration of typical smoke detectors (10%/m). By identifying fires early, it enables timely response and evacuation, protecting lives, equipment, and property from fire. It can detect even trace amounts of smoke that do not reach the ceiling, allowing for quicker responses than conventional smoke detectors and preventing the spread of fire. ■ Detects fires extremely early, buying time for response ■ High flexibility to accommodate any building shape ■ Integration with other systems: can connect to central monitoring systems and external PCs ■ Suitable for data centers receiving Tier 2 or higher facility standard evaluations ■ Ideal for fire prevention against battery abnormalities in power supply equipment and uninterruptible power supplies New product information: Additional accessory lineup - Remote module for remote monitoring - Can connect to the monitoring network of detectors - Compatible with 19-inch subracks

basic information
■Main Features - Wide detection range: 0.001% to 20.0%/m - Multiple alarm levels: Threshold can be set arbitrarily from 0.005% to 20.0% - Ultra-high sensitivity: 10,000 times more sensitive than the nominal operating concentration (10%/m) of conventional smoke detectors - No sensitivity calibration required: By adopting a two-stage filter, the interior of the chamber is kept clean at all times, eliminating the need for sensitivity calibration - Anti-false alarm measures: Flare detection technology using image processing (CMOS camera) and multiple photodiodes (light receiving parts) prevents false alarms caused by dust particles other than smoke, allowing for faster and more accurate detection of trace amounts of smoke at lower concentrations than before - Advanced network construction possible: Open protocol, SLIDING WINDOWS, ModBus, TCP/IP, and relay contacts are available - International standard certified product: Obtained various international standard certifications such as UL and FM Early fire detection / fire early detection / fire early detection system / early detection / early smoke detection / early smoke detection system / fire precursor / fire precursor detection / fire precursor detection system / fire precursor sensor / ultra-high sensitivity smoke / ultra-high sensitivity smoke detection / ultra-high sensitivity smoke detection system / ultra-high sensitivity smoke sensor / ultra-high sensitivity environmental monitoring

Line up（6）
| Model number | overview |
|---|---|
| VESDA-E VEP | VESDA-E VEP is the standard model of the VESDA-E series, capable of setting four alarms (alert, warning, fire 1, fire 2). It also comes standard with features that were previously optional, such as an Ethernet port. |
| VESDA-E VEU | VESDA-E VEU is a high-sensitivity and high-performance model compared to the VESDA-E VEP. Therefore, it can detect a wider area more quickly. |
| VESDA-E VEA | VESDA-E VEA consists of up to 40 microtubes, allowing for pinpoint air sampling to identify individual fire areas. It is particularly suitable for locations where identifying the source of a fire is especially difficult, such as inside electrical panels. |
| VESDA-E VES | VESDA-E VES is a product that can identify fire areas by selecting the pipe with the highest smoke concentration when smoke is detected. VES also allows for the setting of four alarms (alert, warning, fire 1, fire 2). |
| VESDA VLI | VESDA VLI is a durable industrial product designed to meet the needs of monitoring critical assets in harsh environments with high levels of dust and debris. It is utilized in mining sites, manufacturing sites, process facilities, oil plants, power plants, and water treatment facilities, thanks to its patented innovative technology. |
| VESDA VLF | VESDA VLF is a cost-effective ultra-sensitive smoke detection system designed for confined environments. The lineup includes the VLF-250 for small machine rooms and the VLF-500 for medium-sized machine rooms. |
