Redarc HBA1224 Owner's manual

  • Hello! I've reviewed the product details for the REDARC Handbrake Alarm series, including models HBA1224 and HBA1224-003 along with the HBAKIT-001 Mating Connector Kit. This document provides a comprehensive overview of the alarm's features, such as its ability to monitor handbrake and door switches, providing audible and visual warnings and controlling external warning devices. I'm ready to assist with any questions you have regarding its installation or functionality.
  • What voltage systems are the alarms compatible with?
    How does the alarm behave once it is triggered?
    Can the alarm control other warning devices?
    What is the purpose of the mating connector kit?

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.

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.

NOTE: A combination of the two wiring diagrams

door and positive handbrake switches (Install 3),
or positive door and negative handbrake switches
(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.
