The Optical Smoke (KC2-SB4 or KC2-RB4 base required) <br /> Detector uses an advanced pho- <br /> toelectric sensing chamber to discriminate between smoke from a <br /> fire and nuisance smoke from non-fire sources before signaling an Pin 2: Positive IN I Positive OUT <br /> Alarm condition.

Aflashing green LED every 30 seconds indicates Normal con- <br /> dition.A Trouble condition is indicated by a flashing green LED every ®®®® EOL RESISTOR <br /> 5 seconds. A steady red LED indicates an Alarm condition. An5.1 K,0.5 W <br /> TBI,TB2,TB3 <br /> optional Remote LED Indicator is available for convenient viewing.
