Overview
The HB 12/24 has been desigined to work with both 12V/24V vehicles, acting on either a positive or negative
handbrake and door switches. If the door is opened with out the Handbrake applied a latched alarm (both
audiable and visual) will go off and cannot be reset until the Hand Brake has been engaged.
This aids the driver in reducing the incident of exiting the vehicle with out the Handbrake engaged.
Also provided there is a optional Auxillary Alarm feed that can be used to drive a relay to activate the vehicles
horn or similar external alarm device.

sound when the unit has successfully set up.

If there is no alarm then restart the Setup procedure from the start again.
