Multi-sensor fire detector FDOOT241-A
Smoke detector FDO241
Heat detector FDT241
Building Technologies
Fire Safety
● Point detector with additional heat sensors
● Optional detector dust cap to protect the point detector during the
construction phase
Function
● Functions according to the scattered light principle with two sensors: Optical
forward and backward scattering
● Opto-electronic measuring chamber: Obstructs disruptive extraneous light
but can be relied upon to detect 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
Use
● 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 addressed

● Optional detector dust cap to protect the point detector during the
construction phase
Function
● Two heat sensors prevent the total failure of the thermal detection capacity
of in the event of a fault affecting a sensor.
● Measures the operating temperature and the temperature inside the
detector housing so that temperature rise can be detected.
● Selectable detection behavior thanks to application-specific ASA parameter
sets
Use
● For monitoring rooms in which rapid temperature rise is to be expected in
the event of a fire or if optical detection is difficult
● Can be used addressed
