DSC PG4926 433 MHz PowerG Photoelectric Wireless Smoke Detector

The DSC PG4926 is a supervised wireless photoelectric smoke detector engineered for the European 433 MHz PowerG ecosystem. Built on DSC's PowerG two-way wireless protocol, the PG4926 delivers robust, fully supervised life-safety detection suited for commercial and high-end residential installations where interference resilience, long-range RF communication, and continuous device health monitoring are mandatory. The detector generates both audible (built-in 85 dB buzzer) and visual alerts on smoke detection, while simultaneously reporting tamper events, low-battery conditions, and maintenance status back to the control panel. Battery life is rated at up to 8 years under typical use, dramatically reducing operational maintenance overhead. The PG4926 is CE listed and compliant with EN14604:2005/AC:2008, making it the correct variant for CE-regulated markets operating on the 433 MHz band.

Key features & benefits

• PowerG Two-Way Wireless Protocol — Operates on DSC's PowerG communication protocol, enabling fully supervised two-way communication with the control panel for continuous link verification and immediate fault reporting.
• Photoelectric Smoke Detection — Uses photoelectric sensing technology to detect smoke particles accurately, providing early warning of smoldering fires.
• Built-In 85 dB Alarm Buzzer — Integrated 85 dB sounder provides on-site audible alerting directly at the detector, ensuring occupants are warned even before central panel response.
• Comprehensive Supervisory Alerts — Reports smoke alarm events, alarm restores, tamper events (removal from mounting bracket), tamper restores, and low-battery conditions to the control panel, enabling proactive maintenance.
• Visible Link Quality Indication — On-board LED indicator displays wireless link quality at the device, simplifying installation placement and ongoing diagnostics without requiring additional test equipment.
• Extended 8-Year Battery Life — Powered by a single 3V CR123A (consumer) or CR17450 (industrial) lithium cell with up to 8 years of operational life under typical use, minimizing total cost of ownership.
• CE Listed – 433 MHz Band — The PG4926 variant is CE listed and compliant with EN14604:2005/AC:2008, purpose-built for 433 MHz CE-regulated markets across Europe and compatible regions.
• Fully Supervised Operation — Continuous supervision ensures any loss of communication, tamper, or device fault is immediately flagged at the panel, meeting stringent commercial life-safety requirements.
