Addressable Aspiring Systems
The addressable aspirating smoke detection system works by using multiple air sampling points located around your premises, with each point pulling air back through via a network of piping. The air is then sampled through the aspiring smoke detector and analysed. If smoke is detected, this information is relayed to the control panel and an alarm is triggered, giving you the precise location and allowing you to act quickly and effectively.
- Can be deployed in a wide range of different applications.
- Multi-port addressability.
- Unparalleled connectivity and expansion opportunities.
- Field upgradability.
Warehouse (Industrial) Systems
The VESDA Laser Industrial Aspirating Smoke Detector is ideal for use in industrial applications and harsh environments, supporting everything from warehouses to mines, and even livestock/animal facilities. The VLI detector combines a fail-safe Intelligent Filter (patent pending) with an advanced clean-air barrier for optics protection, enabling absolute detection and a long detection chamber life, without the need for re-calibration.
- Can be applied to an enormous number of situations.
- Suitable for Class 1 Division 2 applications- Groups A,B,C, & D.
- Up to 2000 m2.
- Five relays (fire, fault, and 3 configurable).
Gas Detection Systems
Invisible hazards can originate from the release of combustible gases/vapours. VESDA ECO (Ex) uses an existing VESDA pipe network to actively sample air for the presence of these flammable gas/vapours (alcohols), protecting life safety and property whilst ensuring business continuity. This product must be used in conjunction with an existing VESDA but is suitable for use in almost every environment.
- Does not require major retrofitting as it leverages existing systems.
- Provides non-intrusive detection.
- Approved for Class 1 Div 2 applications.
- Enables centralised monitoring and communication with building systems for real-time awareness.
Elevator Shaft Protection
VESDA ASDs work by actively drawing air through sampling holes in a network of pipes that are installed along the elevator shaft and in the elevator machine room. The sampling pipe is connected to a detector with a powerful aspirator that draws the air into a detection chamber to analyse for the presence of smoke.
- Can be connected to a building management system via an existing fire alarm control panel or operate independently to provide alarm information.
- Placed outside the machine room and in shafts to ensure the detector is always accessible for testing and maintenance.
- The sampling holes are typically located at the top of the elevator shaft. In tall buildings, the pipe runs down the shaft vertically to ensure sampling at multiple levels.
Servicing & Maintenance
To maintain a VESDA at optimal performance levels, building owners are advised to schedule regular maintenance and servicing visits through a dedicated provider. The frequency of this servicing will depend on the application. For example, factories or settings with high vehicular traffic will require more frequent servicing since they commonly have higher levels of smoke and pollution.
At Chris Lewis, we can support you with all your VESDA maintenance and servicing needs. From filter replacements to remote work, our expert technicians are highly qualified in the repair of air sampling systems, having worked on a variety of solutions in a variety of buildings.
