About this app

RS485 Fire Panel Monitor turns your Android device into a real-time monitoring station for RS485/ Modbus-connected fire alarm panels — no laptop or dedicated diagnostic hardware required. Connect via USB serial, scan your bus, and get a live, color-coded dashboard of every device on the network.

KEY FEATURES

Automatic device scanning — Sweep all 31 possible slave addresses on your RS485 bus and automatically detect connected panels by device signature. No manual configuration needed.
Multi-device support—Built-in support for FSA, GRP, and MLP fire panel device families, each with its own register map and status logic.
Adaptive dashboard layouts — Whether you have 1 device or 31, the app automatically switches to the right grid layout so every panel's status is visible at a glance.
Live register monitoring—zone status, device health, power source, relay/siren/hooter state, and more—is all polled continuously and color-coded (green/orange/red) for instant status recognition.
Editable device labels — Rename any detected slave with a custom, human-readable name so your team can identify panels by location, not just address number.
Detailed popup view — Tap any device for an expanded, full-screen view of its complete register set.
USB serial connection status — Always know whether you're connected to the bus, with automatic reconnect handling if the connection drops.
TV/remote-friendly navigation — Full D-pad and keyboard navigation support for use on Android TV or industrial touch-free installations.

WHO IT'S FOR

Built for fire alarm system installers, technicians, and facility maintenance teams who need a fast, portable way to verify panel health during commissioning, troubleshooting, or routine inspection — without pulling out a laptop.

HOW IT WORKS

Connect a USB-to-RS485 adapter to your Android device, launch the app, and open Settings to scan the bus. Detected devices are automatically added to your dashboard and polled continuously for live status. Configuration is saved locally, so your device list and settings persist between sessions.
