Advanced Wireless Flood Protection Powered by PowerG® Technology

The DSC® PG9985 PowerG® 915 MHz Wireless Flood Detector is a high-performance wireless water detection sensor designed to provide early warning protection against leaks, standing water, and flood conditions before costly property damage occurs. Built on industry-leading PowerG® encrypted wireless technology, the PG9985 delivers exceptional communication reliability, long wireless range, and secure two-way supervised operation for residential, commercial, industrial, and multi-site security applications.

Engineered for use with DSC PowerSeries Neo®, PowerSeries Pro®, IQ Panel 2 Plus®, IQ4®, and compatible Qolsys® systems, the PG9985 continuously monitors for water at ground level using a supervised 6-foot wired flood probe. When moisture is detected, the sensor immediately transmits an alarm signal to the control panel, allowing users to respond quickly before severe water damage, mold growth, or equipment loss occurs.

Ideal for installation near water heaters, sump pumps, washing machines, utility rooms, basements, HVAC systems, under sinks, data closets, vacation properties, yachts, and mechanical rooms, the PG9985 helps protect high-risk areas vulnerable to plumbing failures or unexpected flooding events.

The fully supervised PowerG® communication platform provides enhanced wireless reliability using frequency hopping spread spectrum technology, adaptive transmission power, and 128-bit AES encryption for secure anti-jamming communication. The detector also features a visible signal quality LED indicator that simplifies installation by helping technicians identify optimal mounting locations without repeated trips back to the control panel.

Unlike many standard flood sensors, the DSC PG9985 includes probe supervision functionality that alerts the system if the water probe becomes disconnected, ensuring continuous monitoring integrity. With up to 8 years of battery life under typical use, low battery reporting, and panel-based configuration, the PG9985 delivers dependable long-term operation with minimal maintenance requirements.

Whether protecting residential homes, commercial facilities, server rooms, vacation homes, retail locations, or critical infrastructure, the DSC® PG9985 provides trusted wireless flood detection designed to help minimize water-related damage and reduce costly downtime.
