Fire detection solutions
Warehouses & other large volume buildings
Warehouses, aircraft hangars, superstores and other large volume storage facilities all present smoke detection problems, including:
- High ceilings mean that smoke stratifies below ceiling level, never reaching detectors installed there.
- High airflow through open delivery doors dilutes smoke, so a traditional smoke detector may not alarm until a fire is quite large.
- Maintenance access to ceiling-mounted detectors is difficult.
- Point-type detectors often false alarm due to dust.
- Building movement and stock placement can cause beam detectors to false alarm.
- Using point-type detectors to cover such large areas can be expensive due to the large number of them required.
A VESDA air sampling smoke detection system overcomes these problems:
- The network of pipes that draw air back to the VESDA detector can be placed where the smoke is most likely to go, ensuring early detection.
- Actively drawing air samples back to the detector counteracts smoke dilution.
- The detector can be placed at ground level so maintenance is easy.
- A built-in filtration system prevents false alarms due to dust or fumes and building movement doesn’t affect a VESDA detector.
- A single VESDA smoke detector can protect an area up to 20,000 sq. ft 2000 m2, making them a cost-effective solution for large volume buildings.
Refrigerated storage
Early detection of a fire in a cold store is critical if food stuffs or pharmaceuticals are not to be contaminated by smoke. Whilst a fire in a cold store might seem unlikely because of the freezing temperatures, electrical components, maintenance activities and arson are all possible sources of fire. Smoke can also enter a cold store from the ceiling space or from external sources. A VESDA very early warning smoke detection system is ideal for harsh environment of a cold store because:
- The VESDA detector can be positioned outside of the refrigerated area. This ensures it is unaffected by the internal sub-zero temperatures and easy to maintain. Only the air sampling pipe network is inside the cold store where it actively collects air samples that are returned to the detector.
- The filtration system and advanced learning capabilities of the VESDA detectors eliminates nuisance alarms due to condensation clouds
- A VESDA system can be designed to specifically suit a facility’s individual layout of freezers, chillers, coolers and loading bays, ceiling void space, plant/maintenance areas and facility monitoring areas. This ensures very early warning no matter where the fire starts.
- FM Global has approved the use of VESDA detectors to activate suppression systems in a cold store. This means that separate heat-activated detectors are not required, a considerable saving for Cold Store owners.
Security solutions
The ADPRO range of video security products can secure multiple geographically-spread warehouses and logistics points from a central location, allowing:
- Confirmation of the arrival/departure and contents of goods deliveries with tamper-proof video evidence
- Video detection of damaged vehicles and goods before they reach their destination
- Verification of drivers, vehicles and their cargo. This ensures that the right truck delivers the right cargo to the right destination.
- Access control, with video identification of drivers and 2-way audio communication between a gate call point and the central monitoring station
- Protection of the perimeter of a site, with passive infrared (PIR) cameras detecting intruders and triggering the automatic transmission of video images to a central monitoring station to assess and respond.
- Virtual guard tours, using CCTV to check that everything at an unsecured drop-lot is OK. This can include monitoring lone workers at isolated facilities.
- Confirmation of the cause of an alarm before sending someone to respond. This reduces the cost of patrolling security guards.
- Interfacing with control systems to do things like turn off lights, open gates or control machinery.
