Fireray 50R/100R

Reflective Infra-red Optical
Beam Smoke Detector


The Fireray 50R/100R optical beam smoke detector series provides economical and effective protection of large open spaces. It comprises of a single unit incorporating an infra-red (IR) transmitter and receiver, with a reflective prism. The system can be connected to a zone of a conventional fire alarm control panel, or interfaced to an analogue addressable system via an interface module. The Fireray 50R/100R offers three selectable 'Alarm Thresholds' settings of 25%, 35% and 50%, which can be chosen to suit the environment.

The Fireray 50R/100R optical beam smoke detector can monitor long-term degradation of beam signal strength caused by the build-up of dirt on its optical surfaces; this operates by regularly comparing the received infrared signal against a reference voltage.
