Optical smoke detector.
The ADR-20R optical smoke detector is designed for detection of visible smoke at a start of a fire’s flameless stage. After exceeding the pre-set threshold value, the detector’s electronic system activates an optical alarm and switches over the output contact of the alarm relay. Connecting a contact into the detector line of the burglar alarm control panel may require using appropriate resistors: alarm and end-ofline (EOL) resistors specific for a given control panel.
The ADR-20R detector is intended to interoperate with detector lines of any burglar alarm system control panels.
