Datasheet Optical/Thermo-velocity Smoke Detector 2.0
LRDFT — Detector multicriterio (optico of smoke + rate-of-rise thermal) linha 2.0 Long Range.
Description
About this model
The LRDFT is a multicriteria optical smoke and rate-of-rise thermal detector from the 2.0 Long Range line, designed to meet the latest requirements and specifications in fire prevention and firefighting.
Following guidelines adopted in European and American standards and in ISO 7240 itself, the use of detectors with more than one detection factor is becoming a prerequisite in the detection sector.
In the 2.0 Long Range line, the LRDFT provides more than 10 times the range of the previous line, allowing fewer repeaters and greater safety in signal propagation.

Fire Detector Multicriterio DC IP41 The Detectors Multicriterio of Smoke and rate-of-rise thermal (DFT and DEF) were designed with os requirements and specifications more recentes of the sector of prevention and firefighting. Por guidelines adopted in standards European, American and na propria ISO 7240 que governs a fabricacao of the equipment in territorio nacional, o uso of detectors with more of a factor of detection esta se becoming pre-requisito no sector of detection. Uma mudanca very important and que na linha 2.0 ou tambem chamada of Long Range, os DFTs and DEFs have a alcance estendido in more of 10 vezes ao alcance of the linha anterior, permitindo a uso with menor quantidade of repeateres and ainda with greater seguranca of propagacao of signal.
