Blue Sea Systems Floyd Bell Turbo Series Alarm, 5-30V DC, Adjustable Volume, 1 in Panel Mount

Overview

The Blue Sea Systems 1070 is a Floyd Bell Turbo Series panel-mount audible alarm for 12V and 24V DC warning circuits. It runs on 5 to 30V DC, fits a 1 inch round panel aperture, and uses a pulsed alarm tone that reaches 103 dB at 30V DC.

This is the kind of alarm that makes sense when you want a clear audible warning at the helm, on a switch panel, or next to a monitoring display without giving up much panel space. The sound level is adjusted at the front bezel, so it is easier to set for an open helm, an enclosed cabin, or another location where background noise changes from boat to boat.

For fit and wiring, the important details are straightforward: it mounts through the panel with a threaded body and locking ring, and it connects with male quick connect terminals in a simple two-wire DC circuit. It works well anywhere a monitoring or control system needs a compact audible alert.

Key features

• Nominal 12V and 24V DC use with a 5 to 30V DC operating range
• Fits a 1 inch round panel cutout for compact installs at the helm or electrical panel
• Rotating front bezel adjusts alarm volume without removing the unit from the panel
• Male quick connect terminals keep wiring simple in a two-wire alarm circuit
• Pulsed tone around 2900 Hz at about 3 beeps per second for a clear warning sound
• Sound output reaches 103 dB at 30V DC and 85 dB at 5V DC
• Threaded body and locking ring hold the alarm securely in the panel

Compatibility and fit

This alarm works in Blue Sea Systems setups that need an external audible warning, including m-LVD units and the M2 monitoring range. It also fits other DC alarm circuits that switch or supply 5 to 30V DC and need a compact panel-mount sounder.

The 1 inch round cutout is the main fit check before ordering. That makes it an easy match for many helm dashboards, switch panels, and instrument panels where space is limited but the warning still needs to be heard clearly.

Installation and setup

Installation is through the front of the panel, then secured from behind with the attachment ring. The quick connect terminals help when access is tight or when the panel may need to come apart later for service.

Once mounted, the bezel can be turned to bring the alarm level up or down to suit the location. That is useful on boats where the same style of alarm may be used in different spaces with very different ambient noise.

Use on board

This is a practical choice for boats that use panel alarms for battery, bilge, tank, or other monitored DC conditions and want a warning that is easy to hear without adding a larger siren. It suits owners and installers looking for a compact alarm that fits common marine panel layouts and straightforward 12V or 24V electrical systems.
