10.6 Multi-sensor fire detector FDOOT241-A9-Ex
Device for zone 0, 1 and 2 areas at risk of explosion
10.6.1 Functions
●
Functions according to the scattered light principle with two sensors, optical
forward and backward scattering
●
Opto-electronic measuring chamber which obstructs disruptive extraneous light
but provides excellent detection of both light and dark smoke particles
●
Two additional heat sensors increase the fire detector's immunity to deceptive
phenomena
●
Can be set as a multi-sensor smoke detector, smoke detector, or heat detector
by the software
●
Selectable detection behavior thanks to application-specific ASA parameter
sets
●
Multi-protocol: Collective / GMT (Cerberus / Siemens), SynoLINE300 and
FDnet-Ex
Observe national guidelines and regulations.
●
Fields of application:
– For early detection of flaming fires of solid and liquid substances as well as
of smoldering fires
– For early and reliable fire detection in an environment with deceptive
phenomena
– Can be used either addressed or collectively
Efficiency on-site
●
Exchange the detector with detector exchanger FDUD291 without resetting the
parameters
●
Exchange the detector with detector exchanger FDUD291 without a ladder at
heights up to 8 m
