The REDARC HBA1224 Handbrake Alarm is designed for use in 12V or 24V automotive systems. It monitors the handbrake switch and the doorframe switch to provide both an audible and visual warning if the door is opened while the handbrake is not applied. Once triggered, the alarm latches on and stays active until the handbrake is applied — even if the door is closed again.

The HBA1224 improves vehicle safety in several important ways:

It reduces the risk of a vehicle being accidentally left unattended without the handbrake on.
When used with an external relay or horn, it can alert anyone in the general area that a vehicle has been left without its handbrake applied.

Hummingbird Electronics offer an optional external compact combination warning LED and buzzer which is well suited for use with REDARC's Handbrake Alarm. This accessory is available in both 12V and 24V variants.

Applications

Handbrake alarms are a mandatory health and safety installation on many mining site vehicles, providing critical protection against runaway vehicle incidents. The HBA1224 is equally suited to any commercial fleet, agricultural operation or work vehicle where handbrake safety is a priority.

Note: The doorframe switch referenced is the switch mounted in the doorframe that activates the cab light when the door is opened.

What triggers the HBA1224 handbrake alarm?

The alarm activates when the vehicle's door is opened (detected via the doorframe switch) while the handbrake has not been applied.

Will the alarm turn off if I close the door again?

No — once triggered, the alarm latches on and remains active until the handbrake is physically applied, regardless of whether the door is closed.

Can the alarm warn people outside the vehicle as well?

Yes — using the external output with a relay and horn, the alarm can alert anyone in the surrounding area that a vehicle has been left without its handbrake on.

Is a handbrake alarm mandatory in any industries?

Yes — handbrake alarms are a mandatory health and safety installation on many mining site vehicles and are commonly required across other industries with strict OHS obligations.
