The DiT's DD1 is a water point detector, featuring gold-plated probes and microchip technology for the highest level of water detection confidence. The DD1 can be operated from12-25 Volts AC or DC. Alarm and control signaling is provided with form “C” relay contacts.The DD1 can be connected to any of DiT’s monitoring systems to complete the monitoringpackage. The DD1 can also be used as a stand-alone controller for cooling or water flowshutdown.OPERATIONMonitoringThe DD1 can be used with any “contact-closure” monitoring panel. The “dry” contact pointsmay be wired normally open or normally closed, allowing wiring flexibility to handle mostinstallations. DD1-S contacts operate reverse of the DD1’s.ControlAir ConditioningThe DD1 relay contacts can be used to inhibit cooling when a high water level in a drainpan is detected. This will prevent water damage to the ceiling or flooring due to a cloggedcondensate drain.Water HeatersThe DD1 relay contacts can be used to close an electric solenoid when a water heater isdripping into an emergency drain pan. This will prevent serious water damage to the building should the emergency drain pan become clogged.MOUNTINGThe DD1 sensing-probe, clips to the drain pan using a galvanized mounting bracket. Thesensing probe is adjustable for maintaining the proper water level. The control module canbe mounted on any flat, smooth surface using the mounting holes in the module feet.
