The Opal addressable beam detector is an intelligent reflector type linear optical beam smoke detector designed to operate with Notifier addressable fire alarm systems. It operates primarily on the principle of light obscuration utilising infra-red light.
The Infra-Red transmitter generates a beam of light towards a high efficiency reflector. The reflector returns the beam to the receiver where an analysis of the received signal is made. The change in the strength of the received signal is used to determine the alarm condition.
Opal beam detectors are combined transmitter/receiver units, which
can be directly connected to a Notifier Opal protocol addressable loop. The NFXI-BEAM-E is entirely loop powered without the need of a separate local power supply. The unique servo test feature of the NFXI-BEAM-TE requires 24Vdc @ 0.5A.
