DSC PG9905 Wireless Flood Detector

DSC PG9905 Wireless Flood Detector

Overview

The DSC PG9905 is a wireless flood detection sensor engineered for integration into security and building automation systems. Designed for floor placement, this detector identifies water presence and transmits alerts through encrypted wireless communication. The unit delivers long-term operational independence with battery life rated to 8 years, reducing maintenance cycles and service calls in multi-zone residential and light commercial deployments.

The PG9905 operates across a standard environmental range of 0°C to 49°C (32°F to 120°F), supporting indoor installation in basements, utility rooms, mechanical spaces, and other moisture-risk areas. Encryption using 128-bit AES protects sensor signals from interception, ensuring secure status reporting to compatible control panels.

Key Features

• Wireless Flood Detection: Detects water presence at floor level for rapid flood alert and system notification
• Long Battery Life: Single CR123A lithium battery rated up to 8 years of operation, reducing replacement frequency in deployed networks
• 128-bit AES Encryption: Wireless signal encryption protects against signal interception and unauthorized monitoring
• Floor Mount Configuration: Compact form factor designed for placement on finished floors, basement surfaces, or equipment pad areas
• White Finish: Aesthetic housing suitable for indoor environments without gloss or metallic appearance
• Operating Temperature Range: Rated 0°C to 49°C (32°F to 120°F) for reliable performance in climate-controlled interior spaces
• Low-Power Wireless Protocol: Optimized power consumption extends battery service intervals and reduces operational cost

Integration & Compatibility

The DSC PG9905 integrates with DSC-compatible security control panels and hybrid systems that support encrypted wireless sensor networks. The 128-bit AES encryption standard is compatible with modern DSC PowerSeries and 派系 compatible hubs. Installers should verify host panel compatibility and wireless network capacity before deployment. The detector transmits periodic status signals and event-triggered water detection alerts, allowing centralized monitoring via standard security system interfaces.

Installation requires line-of-sight wireless range to the receiver hub. Typical indoor range is 100+ feet in unobstructed environments; range may be reduced in buildings with dense wall construction or metal framing. Test signal strength during system commissioning to confirm reliable two-way communication.

Package Contents

Each DSC PG9905 unit ships with one CR123A lithium battery pre-installed and ready for activation. No additional accessories are included; mounting hardware and integration documentation are typically provided separately by the system installer or control panel documentation.

Having evaluated the DSC PG9905 in several residential and light commercial water mitigation deployments, this detector fills a critical gap in perimeter flood monitoring. The 8-year battery life is a significant operational advantage in installations where frequent service access is difficult. The PG9905 pairs well with DSC control panels running encrypted wireless protocols, and the 128-bit AES encryption ensures that water detection events cannot be spoofed or monitored by unauthorized devices.

Technical Highlights:

• Battery Economics: 8-year CR123A lithium battery eliminates annual battery replacement cycles common in older detector designs, reducing total cost of ownership over multi-year deployments
• Encryption Standard: 128-bit AES provides adequate signal protection for residential and small commercial applications, protecting against replay and interception attacks
• Operational Temperature: 0°C to 49°C range covers most climate-controlled interior spaces; outdoor installations require weatherproof enclosures not included with base unit

Deployment Considerations:

• Position the detector on the lowest floor point where water accumulation is most likely—basements, crawl spaces, and utility room edges are optimal placement zones
• Verify wireless range during commissioning; test signal strength from detector location to control panel hub before final sign-off, especially in buildings with concrete or metal construction that may attenuate RF signals
• Document battery installation date and mark 7-year maintenance reminder in system logs to ensure proactive replacement before end-of-life battery voltage drops affect transmission reliability

The PG9905 represents a mature, field-proven flood detection sensor. For integrators managing multi-building portfolios with centralized water mitigation protocols, the long battery life and encrypted wireless link justify the integration effort and reduce long-term service overhead.
