System Sensor’s i3 series accessories are for the company’s i3 series of photoelectric smoke detectors. The loop test/maintenance module provides visual indication when the detector requires cleaning. The sensitivity reader measures sensitivity using an IR signal and displays the information in terms of percent per foot obscuration. The reversing relay/synchronization module allows all i3 sounder detectors on the loop to sound when one alarms by reversing the polarity to the detector zone. The removal tool simplifies servicing of detectors by attaching to a standard extension pole or broom handle. The adapter bracket covers up unsightly rings and unfinished surfaces for retrofit installations. System Sensor
