The Potter PAD300-4DB 4-Inch Addressable Detector Base provides a reliable mounting and electrical connection solution for compatible Potter addressable fire alarm detectors. Its compact, low-profile design supports professional fire alarm installations. In addition, the base features polarity-marked terminals and flexible mounting options for different electrical box configurations.
Four-Inch Addressable Detector Base
The Potter PAD300-4DB belongs to Potter’s PAD300 D-TECT family of addressable fire alarm accessories. It provides a secure mounting platform for compatible detector heads.
The four-inch design offers a compact installation footprint. Therefore, it works well in locations where a smaller detector base is preferred.
The base also provides the electrical connections needed between the detector and the signaling line circuit.
Compatible Potter Addressable Detectors
This mounting base supports compatible Potter PAD300 Series detectors. These include selected photoelectric smoke detectors, heat detectors, and combination sensing models.
For example, the PAD300-PD photoelectric smoke detector uses compatible PAD300 mounting bases. Other supported detector models may require specific configurations.
Therefore, installers should verify the exact detector model before selecting a mounting base.
The base itself does not detect smoke or heat. Instead, it supports the compatible detector head and provides the required circuit connections.
Polarity-Marked Wiring Terminals
The base includes screw-clamp terminals with polarity markings. These markings help technicians identify the correct wiring connections during installation.
In addition, duplicate terminals support incoming and outgoing Signaling Line Circuit wiring.
This arrangement allows installers to connect compatible SLC conductors without placing multiple wires under a single terminal.
As a result, the base supports organized wiring and convenient system maintenance.

Detector Locking Feature
The Potter PAD300-4DB includes a locking tab that can help prevent unauthorized detector removal.
Installers can activate this feature during installation. Once enabled, the locking mechanism secures the detector head to the base.
To remove the detector, technicians must use a small screwdriver to release the locking tab while turning the detector head.
Therefore, the locking feature provides additional protection in locations where unauthorized removal may be a concern.
Flexible Mounting Options
This detector base supports several common electrical box configurations.
Compatible mounting options include single-gang, double-gang, octagonal, and four-inch square electrical boxes.
The mounting design provides flexibility for new construction and replacement projects. Moreover, it allows technicians to use existing electrical boxes when the installation meets manufacturer requirements.
Fire Alarm Applications
The four-inch detector base supports compatible commercial and institutional fire alarm systems.
Typical applications include office buildings, schools, healthcare facilities, warehouses, hotels, retail properties, and industrial facilities.
In addition, the compact design makes it suitable for replacement projects involving compatible Potter addressable detectors.
Installation and Compatibility
Before installation, confirm the detector model, SLC wiring requirements, electrical box configuration, and control panel compatibility.
Also, verify the wire size and polarity markings before connecting the signaling line circuit.
Qualified fire alarm professionals should install and test the assembly. Furthermore, technicians should follow Potter installation instructions and applicable fire alarm codes.
Overall, this Potter detector mounting base provides a practical solution for compatible addressable fire alarm systems. Its compact design, flexible mounting options, secure locking feature, and convenient wiring terminals make it suitable for professional fire alarm installations.
