VESDA Aspirating Smoke Detection Systems

VESDA stands for Very Early Smoke Detection Apparatus. These aspirating smoke detection systems are used where early warning to a fire is fundamental. If servicing of a conventional system is problematic or aesthetics are a major consideration such as in luxury flats and houses or listed buildings, a VESDA system can be an ideal solution.

Automatic Opening Vents release smoke from residential corridors particularly in “Stay in place” scenarios. AOV systems can be integrated with a fire control panel for enhanced fire prevention.

Voice alarm systems are often installed in place of conventional sounders particularly where phased evacuation is a requirement.

DDA fire alarm systems are frequently combined with intercom systems to assist in the evacuation of disabled individuals in the event of a fire. These are often included as part of a nurse call system in assisted living environments, where a panic alarm can be used to allow patients to alert nursing staff for assistance in an emergency.
