BRK Electronics 680MBX Mains 230V Ionisation Smoke Alarm with 9V Battery Backup
Finding a matching fire alarm unit is very hard because BRK stopped making the 600 series. However, a faulty alarm leaves your building unprotected and compromises your entire interlinked safety network.
Fortunately, we have sourced a small batch of genuine, brand-new, old stock (NOS) BRK 680MBX units. These alarms are pristine and completely unused. Furthermore, we ship them in their original factory boxes.
Why Buy New Old Stock (NOS) BRK 680MBX?
- No Extra Rewiring: First, this unit fits directly onto your current BRK twist-fit baseplate. Consequently, you do not need an electrician to change the ceiling mounting plate.
- Keep Your Network Safe: Second, this unit links seamlessly with your existing BRK smoke detectors. Thus, your entire home warning system stays fully uniform.
- Fast Fire Detection: Finally, the ionization sensor responds incredibly quickly to fast-flaming fires. For that reason, it provides critical early warnings when every single second counts.
Key Features & Technical Specs:
- Power Source: 230V AC mains hardwired fire alarm unit.
- Battery Backup: Standard 9V alkaline battery is inside the box. Note: We recommend a fresh battery due to storage age.
- Base Compatibility: Fits all existing BRK 600 series twist bases.
- Interlinking Capable: Connects easily with up to 12 compatible BRK units.
- Test Controls: Large front button handles regular function testing.
Please Note: BRK discontinued this line. For that reason, the original maker warranty may be expired. However, we fully guarantee that this unit works when it arrives.
