Grote 73250 backup alarm

The Grote 73250 backup alarm produces a tonal alert at 107 dB for vehicle safety. It operates on 12-24V DC systems with a current draw of .3 A. The blue glass/nylon housing measures 2 in length by 4 3/16 in width and height. A grommet mount and blunt-cut wires simplify installation.

Practical limits of 107 dB tonal output

The fixed tonal pattern meets SAE Type B requirements for medium-duty applications. Reverse-facing speaker direction projects sound toward the hazard zone behind the vehicle. Adjustable output levels allow tuning for specific site conditions. The IP rating is not applicable, so exposure to water or dust should be evaluated before mounting.

Replaces lower-output or non-adjustable alarms

This unit upgrades from alarms lacking selectable volume or SAE Type B compliance. The jump is worth it when regulations demand 107 dB output or when operators need quieter settings for confined work areas. It does not suit buyers who want multi-tone patterns or integrated lighting functions.

Questions about this item

Does the 73250 offer different output levels or just the single 107 dB tone?

The alarm features adjustable output levels so you can set the volume lower than the maximum 107 dB if required.

Will 107 dB be audible inside a loaded truck cab with the engine running?

At 107 dB the tonal signal is designed to meet SAE Type B requirements and cut through typical cab noise and diesel idle.

The blunt-cut wires connect to 12 V or 24 V systems — does the alarm auto-detect the voltage?

Yes, the unit operates on 12-24 V DC without any selector switch or jumper.
