3. ENGLISH 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 e transmitter receiver unit FLR100 Tx Rx passive reflector e 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
