Intelligent Detectors with Isolators VELOX addressable detectors employ optical and thermal detection technologies to sense fire conditions.
VELOX 40000 Series

VELOX addressable detectors employ optical and thermal detection technologies to sense fire conditions.

The 40910, 40920, and 40930 range of detectors come with inbuilt short circuit isolators and a bi-colour (red/green) LED for 360 visibility.

Combination of optical and thermal detection in a single detector head saves costs and spots both slow smoldering and high energy flaming fires.

Up to 240 devices can be connected on a single loop, which can extend to 2 km as per load calculations and cable selections.

The devices are powered from the same fire detection loop which connects the fire alarm control panel, sounders, beacons, manual call points, etc. Therefore, additional power supply sources are not required.

Various options of detection technology

The VELOX intelligent smoke detectors operates on the light scattering principle, which makes the detector an excellent choice for smoldering fires “thanks to the advanced algorithms in built on each detector head.”

The combination of Smoke Scattering with the centralized low inertia thermistor makes the Velox detector the best choice as a general detector to most types of fires, smoldering and fast burning fires.

The detector is equipped with 10 sensitivity levels allowing the detector to operate according to user desire.

The VELOX intelligent heat detectors operates on the centrally positioned thermal thermistor principle, which makes the detector an excellent choice to detect high energy emitting fires as well as low energy heat emitting fires that gradually increases with time, thanks for the advanced algorithms embedded in the detector head as well as the approved two sensitivity levels A1R which is Rate of Rise Detection of 58Cº as well as the Class B which is High Temperature of up to 78Cº.

Physical construction and assembly

The VELOX range of products is constructed from a high impact, elegant ABS white enclosure, and the patented

360º symmetrical smoke chamber allows the smoke to easily enter the chamber from all the directions. The chamber is complete with a patented Double Dust Trap “DDT” that protects the chamber from airborne contaminants thus reducing the problem of false alarms.

The detector is supplied with a continuous screen, where protecting the smoke chamber from small in- sects.

Commissioning is never easier

ATEIS wants to make it easy to the installer, no dip or rotary switches are required to address the detectors nor barcode scanners or other difficult methods of installation are needed. Automatic addressing is an added benefit to the many others of VELOX technology, were the fire alarm control panel addresses each device in a sequential manner, and make sure that no duplicate addresses are allowed. Furthermore when needed to assign an address in a non-sequential fashion, the manual programming via the VELOX detector programming tool is utilized.

VELOX magnetic test simulates the action of an alarm in the detector to drive the cause & effect and test the detector’s functions when testing an installation.

Adaptive Drift Compensation

The sophisticated algorithms inside each detector, provides decentralized intelligence to compensate the obscuration measurements in case of dust and other similar contaminates inside the chamber. The “ADC” technology keeps the detection threshold window uniform with fixed detection sensitivity, unlike other drift compensation methods in the market that reduces the detection threshold window allowing a change in sensitivity.
