Description
The Potter PAD300-PD analog addressable smoke detector provides advanced fire detection optimized for commercial properties, health facilities, and multi-tenant residential networks. Equipped with an optical chamber, the device continually analyzes local air density to flag smoldering fires while using internal filtering algorithms to ignore typical household cooking smoke or steam. It interfaces with compatible Potter addressable fire panels by continually sharing real-time obscuration metrics over the 2-wire Signaling Line Circuit (SLC). To streamline commissioning, the rear of the device includes a mechanical 7-position DIP switch array for field addressing, removing any dependence on specialized programming wands. Built with a high-impact, eggshell white thermoplastic shell, the sensor features a rapid under-five-second polling cycle, an integrated magnetic testing strip, and a twist-lock interface that connects directly to the entire family of PAD300 series mounting bases.
Features
- Advanced Photoelectric Chamber: Specially tuned to target visible smoke particles from slow-smoldering fires while mitigating false triggers from environmental moisture or minor cooking vapors.
- Onboard Drift Compensation: Automatically realigns the detector’s baseline calibration over time as dust gathers, keeping system sensitivity consistent and reducing nuisance alarms.
- Proactive Maintenance Warnings: Communicates real-time contamination levels directly to the fire panel, signaling a dirty head alert so integrators can clean or service the unit before it faults.
- Hardware-Based Field Addressing: Employs an accessible rear-mounted DIP switch array that lets technicians set the unique binary SLC address (1–127) without a handheld programming tool.
- Integrated Insect Screening: Fitted with a protective internal screen surrounding the optical sensor array to stop bugs and floating debris from infiltrating the critical measurement chamber.
- Broad Base Compatibility: Twists securely onto any standard PAD300 series mounting layout, including standard 4-inch (PAD300-4DB), 6-inch (PAD300-6DB), isolator, relay, and
