The SB Series is a 6" polarized base with annunciator output featuring a current limiting resistor, and a blocking diode to enhance annunciator function. The SB Series Smoke Detector base is designed specifically for use with the Potter Smoke Detector Models IS-24, PS-24 and PS-24H.

These detectors will not sense fires which start where smoke does not reach the detector.
Fires on other building levels, within walls, on roofs , in chimneys, or on the other side of closed doors may not be detected.
Fires from explosions, improperly stored flammable liquids, escaping gas, arson or fires resulting from inadequate fire protection practices may not be detected.
Smoke detectors should be tested upon completion of installation and at least semi-annually thereafter, in accordance with the section of "Inspections, Tests, and Maintenance" in NFPA-72.
To Install the Detector: Insert the detector into the base, turn the detector clockwise until it locks, then tighten the vandal resistant allen screw
