Detectoare de fum

1. Dx700 Detectors
700 Series Conventional Multi Detector w/ Relay Output & Auto
Reset Feature
DP721RTA
The DP721RTAis a multi-sensor detector (optical enhanced by
heat) with field exchangeable optical chamber and local relay
output facilities. This detector will automaticallyresetwhen the
fire alarm condition has been removed.The detector uses a
combination of detection criteria from both optical and heat
sensors to determine whether there is cause ofalarm in its
area.
700 Series detectors continuallymonitor their own sensitivityand
operational status.Once a day they perform a full diagnostic testthat
includes dynamicallytesting the sensing chamber and internal
electronics.

Siemens OH720 se foloseste la detectarea flacarilor cauzate de catre arderea materialelor lichide si solide, precum si focului
mocnit. Pentru detectarea sigura a incendiului in medii cu fenomene inselatoare. Functioneaza conform principiului dispersata
de lumina, cu un senzor optic de imprastiere inainte. Un senzor de caldura suplimentar mareste imunitatea detectorului de
fum impotriva alarmelor false. Comportament de detectare selectabil de catre diferite seturi de parametri. Baza trebuie
comandata separat.
