Smoke detection system

A major chemical treatment centre in Budapest is using a Fireray 5000 and 14 Fireray F50R reflective infrared beam smoke detectors as part of its fire protection system.

The system was designed and installed by Fire Fighting Enterprises' Hungarian distributor Elektrovill Biztonságtechnikai Zrt. The beam detectors are being used to cover large, open areas of the centre, as the wall-mounting and massive detection area per unit make them an efficient and effective option.

Each Fireray F50R unit can protect an area of up to 750m2 from a single wired installation point on a wall near the ceiling. The F50R hosts the IR beam transmitter and receiver in the same housing, with the beam being aimed at a prismatic reflector plate on the opposite wall to the unit.

Smoke entering the beam path causes interference and reduction in signal strength, resulting in an alarm signal when a preset threshold is reached.

In the treatment centre, detectors are situated in warehousing and storage areas, which have the type of open-plan architecture and high ceilings that make the most of the beam detectors' particular features.

Although not necessary in this instance, ATEXapproved Fireray models are also available for use in explosion-risk environments.
