Datasheet Optical/Thermo-velocity Smoke Detector 2.0 (Between Linings)
LRDFE — Detector multicriterio (optico of smoke + rate-of-rise thermal) versao between ceilings.
Description
About this model
The LRDFE is a multicriteria optical smoke and rate-of-rise thermal detector from the 2.0 Long Range line, developed for detection between ceilings, installed between the slab and the suspended ceiling.
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 LRDFE provides more than 10 times the range of the previous line, allowing fewer repeaters and greater safety in signal propagation for between-ceiling applications.

Fire Detector Multicriterio Entre Forros DC IP41 Versao between ceilings of the Detectors Multicriterio of Smoke and rate-of-rise thermal (DFT/DEF), designed for installation in spaces entre slab and dropped ceiling. Mesma tecnologia of the linha 2.0 (Long Range) with alcance estendido in more of 10 vezes ao of the linha anterior, permitindo uso with menor quantidade of repeateres and greater seguranca of propagacao of the signal. Combina detection optical of smoke with sensor rate-of-rise thermal, serving os requirements and specifications more recentes of the ISO 7240 and of the standards European and American of detection multicriterio.
