UNIQUE FIRE MONITORING CAPABILITY WITH BEST DETECTION PERFORMANCE

Unsurpassed quality and reliability bring you peace of mind and lower cost of ownership

A blazing fire can have devastating consequences: risk to human life, damage to valuable infrastructure, and long down-times. A proper fire protection installation is made more complex when the area is affected by harsh environmental conditions. Industrial facilities frequently produce dirt, dust, humidity and corrosive atmospheres in the production, storage or transport of goods. Conventional sensor technology often fails and tends to produce false alarms. These technologies require periodic, time-consuming maintenance efforts.

AP Sensing’s unique linear heat detection solution reduces operational costs and offers maximum reliability even under severe conditions like:

Dirt, dust and corrosive atmospheres
High humidity and extreme temperature changes
Solvent vapors and radioactivity
ATEX classified areas (risk of dirt or gas explosions)

DISTRIBUTED TEMPERATURE SENSING

Our solution is thoroughly tested and certified (VdS, UL, FM, ATEX, IECEx, SIL) with the industry's fastest fire detection and lowest false alarm rate. Our Distributed Temperature Sensing (DTS) fiber-optic linear heat detection system detects fires precisely and can accurately track the size and direction of a spreading fire, regardless of air currents. No other fire detection system can withstand temperatures up to 1000 °C (1800 °F) without losing monitoring capabilities. With this unique feature, fire-fighting countermeasures can be used effectively during the fire event. Our solution includes certified, maintenance-free sensor cables with an expected lifespan of 30 years to fit your requirements.

SMARTVISION™

AP Sensing's SmartVision™ software show the alarm zones, operational status, and real time temperatures at a glance, controlled by an easy-to-use graphical interface. It seamlessly integrates many sensors into a single platform. Monitored facilities are mapped and color-coded to show the measured temperatures, alarm zones, fire locations, as well as fire size and spreading. Alarm zones can be individually defined for flexible alarm levels and types.

APPLICATIONS
