SENTINEL ALARM SYSTEM
FUNCTION: The Sentinel Alarm System is designed to be installed in an existing floor cleanout closure plug to notify the building maintenance staff or homeowner whenever there is a backup condition detected in the sewer line. The backup may occur due to a drainage system blockage, the system's inability to handle peak flow during a storm surge or backflow from the street sewer. The Sentinel Alarm System is activated by a pressure increase in the vertical portion of the sewer cleanout tee due to a backup condition.
 
REGULARLY FURNISHED:
