Type: Owner's manual

Redarc HBA1224 is a handbrake alarm that can be used in 12 V or 24 V automotive systems. It monitors the handbrake switch and the door frame switch to provide audible and visual warning if the door is opened while the handbrake is not applied. Once the alarm starts, it stays latched on until the handbrake is applied, even if the door is closed again. The HBA1224 has several features that make it a valuable safety device for any vehicle. These features include:

Reducing the risk of the vehicle being accidentally left unattended without the handbrake on
Controlling an optional additional warning device such as a siren or horn (with the use of a suitable relay) or a suitably rated piezoelectric buzzer or a strobe beacon

Reducing the risk of the vehicle being accidentally left unattended without the handbrake on
Controlling an optional additional warning device such as a siren or horn (with the use of a suitable relay) or a suitably rated piezoelectric buzzer or a strobe beacon

HBA1224‑003 KIT OPTIONS

Each item can be purchased individually (HBA1224‑003 and HBAKIT‑001) or as a combined kit

(HBA1224‑003‑KIT1). HBAKIT‑001 is required to interface with the HBA1224‑003 if the installation does not

already have a mating connector or a ready mating loom.

The HBA1224 / HBA1224‑003 handbrake alarm is

used in 12V or 24V automotive systems. It monitors

the handbrake switch and the door frame switch*

to provide audible and visual warning if the door is

opened while the handbrake is not applied. Once the

alarm starts, it stays latched on until the handbrake is

applied, even if the door is closed again.

The HBA Series improves vehicle safety by:

• Reducing the risk of the vehicle being accidentally

left unattended without the handbrake on.

• Controlling an optional additional warning device

such as a siren or horn (with the use of a suitable

relay) or a suitably rated piezoelectric buzzer or a

strobe beacon.

* The door frame switch is the switch mounted in the door frame

that switches on the cab light when the door is opened.

FEATURES

• External output for buzzer or relay

• Latching alarm function

• Ground and positive door frame switch inputs

• Ground and positive handbrake switch inputs

WIRING

• Refer to the wiring diagrams for details on wiring

the HBA1224/HBA1224‑003. Two options are

illustrated as a guide, depending on how the

vehicle handbrake switch is wired. Refer to the

table for other wiring conﬁgurations.

• If the vehicle has a positive door switch for the

dome light, the wire must be cut and a diode

must be added in order to prevent false alarms

from the manual dome switch. This diode must

be rated to supply dome light(s).

• The optional output (grey wire) can be used

to drive an additional load or relay, provided

that the current does not exceed 0.5 A. For

example, the additional load may be a suitably

rated piezoelectric buzzer or a strobe beacon,

conveniently placed to ensure that any warning

is detected by the driver. Note — some modern

resistor and diode protected relays draw more

than 0.5A.

• All unused wires should be taped over

(applicable to HBA1224).

• The Handbrake Negative input (Green wire)

has speciﬁc operating voltage requirements.

Care should be taken if other circuits, electronic

controls or power circuits are connected to

this input which may cause voltages other

than battery positive or negative. The following

speciﬁcation applies:

Handbrake On: Battery Negative ±2VDC

Handbrake Off: Battery Positive ±2VDC

CAUTION

• Care must be taken to avoid overloading

the outputs. The optional output is

rated at 0.5A max. In ground switched

applications, the outputs for the dome

light(s) and the dashboard light are 2A

max. If higher currents are required,

suitably rated relays must be added.

• The HBA1224 relies on the switches

operated by the handbrake and the

door. Each of these switches should be

functionally tested on a regular basis in

conjunction with the Handbrake Alarm to

ensure correct operation.

• The HBA1224 is a reminder only; it does

not monitor how ﬁrmly the handbrake is

applied. The operator must ensure the

handbrake is operated in a manner that

maintains

vehicle safety.

• Some full air brake and air/hydraulic

brake systems do not have a switch on

the handbrake lever itself. The handbrake

relay on the air valve should be used for

indication that the handbrake is applied on

these vehicles.

(Install 4). Refer to the table below.

** If relays are connected to HBA inputs or outputs they

must have diode suppressed coils.

*** The Grey wire is capable of 0.5A max. For loads

larger than 0.5A, this wire should be used to power a

suitably rated diode suppressed external relay.
