The DET-2R-IO is a radio-operated device that provides one wired zone input (typically used as a water leak detector) and one wired output. Enabling wireless transmissions to a wider intruder alarm system, the versatile device features Scantronic Secure Radio (SSR); SSR is an advanced, bidirectional, encrypted radio system which accelerates response times and enables quick status reports, granting homeowners peace of mind. When used as a flood sensor, the DET-2R-IO can be programmed to set a warning on detecting water or on becoming dry.
