GENERAL DESCRIPTION
FLR100 and FL100 are the optical beam smoke detectors whose working principle is based on the
attenuation of the light intensity of an infrared light beam due to smoke.
The infrared light beam is transmitted by a transmitter unit (Tx) and received and properly processed by a
receiver unit (Rx).
More specifically, the receiver unit Rx processes an electrical signal proportional to the intensity of the
received light and notifies an alarm or fault condition if the signal falls below an alarm or fault threshold
continuously for a predefined amount of time.
FLR100 and FL100 can work in either one of the following configurations:
• transmitter/receiver unit FLR100 (Tx/Rx) + passive reflector
• transmitter unit FL100 (Tx) + receiver unit FL100 (Rx)
The former requires a single device FLR100, configured to work simultaneously as transmitter and receiver,
and a passive reflector whose purpose is to reflect towards the receiver the light beam sent by the
transmitter.
The latter involves two separate FL100 devices, one configured to work exclusively as transmitter and one
as receiver.
FLR100 and FL100 are equipped with three LED indicators and two 7-segment displays for notification of
several types of information. Also, there are a fault relay and two relays used to signal the pre-alarm and
alarm conditions.
FLR100 and FL100 can be connected to a conventional fire detection circuit for signalling any alarm
condition to the control panel.
CONTENTS OF THE PACKAGE
The package of the optical beam smoke detector contains the following items:
Optical beam smoke detector FLR100
• 1 transmitter/receiver unit
• 1 filter for alarm and fault condition verification
• 1 installation and user manual
• 4 plastic stoppers
• 1 rubber gasket
Optical beam smoke detector FL100
• 1 transmitter unit
• 1 receiver unit
• 1 filter for alarm and fault condition verification
• 1 installation and user manual
• 8 plastic stoppers
• 2 rubber gaskets
The transmitter unit differs from the receiver unit because on the optical section of the transmitter a lens is
mounted and is clearly visible.
Warning: since the device contains fragile optical parts, it is recommended to protect it from accidental
falls and hits.
