When
Safety
Matters
The Combo 64 is an advanced safety device aimed to simplify, control
and warn a driver in case of a problem.
It utilises the latest digital, micro controller technology to ensure
reliability and performance.
It allows for automatic control of preset devices inside the cabin of a
vehicle.
Utilising six inputs and four outputs, the Combo 64 can automatically
warn a driver that the hand brake is not on, can turn on DRL’s as a
preset function, turn beacons on and has many more applications.

Connection
The Combo 64 is an advanced safety device aimed to simplify control, and to warn the
operatorshould a safety parameter be breached.
It utilises the latest digital micro-controller technology to ensure reliability and
performance.
These instructions are intended for use by an authorised installer.
Modifications, manipulations or improper repairs can affect the operability and safety.
There are two connection options shown in the wiring diagrams below. In the typical
connection, Output 4 Common should be connected to ground, if the accessory requires
negative switching.
The Alternative Connection shows the wiring required if the accessory running
through Output 4requires positive switching.

Operation Overview
Mount the Combo 64 in a dry safe, secure place away from the heat and humidity.
If possible,select an inconspicuous area that will not be routinely accessed.
Make sure the device is kept clear of moving parts or debris.
Also ensure the device is safe from moisture or liquids.
Please ensure you read this complete manual as fitting instructions and testing
procedures areincorporated throughout.
General Input 1 and General Input 2 are momentary inputs, briefly connect the input to
battery + or battery negative (depending on the DIP switch setting) to toggle on and off
General Output 1 and General Output 2 respectively.
If General Input DIP switch is enabled (ON), releasing the Park Brake will switch OFF
General Output 1 and General Output 2.
The Door Switch and Park Brake switches are set to Low Active (by Default) but can be
configured either way. If Door Switch is active (Open) while Park Brake is NOT active
(OFF), the on board buzzer will immediately sound for 5s before alarm (Output 4) is
activated. Applying the Park Brake will disable BOTH buzzer and alarm immediately.
Once the door is opened, the alarms latch on unless the park Brake is applied. It is good
practice to apply the park brake BEFORE opening the door.
If Daytime Running Light is set to be controlled by Battery Voltage sensing, Day Time
Running Light (Output 3) is turned ON with a delay of 5s once the engine is running and
the Alternator is charging. If either the Head Light or Park Light is turned ON the DRL’s
are turned OFF immediately. The DRL’s are also turned off with a delay of 20s once the
battery voltage falls below the pre set threshold setting.
If Daytime Running Light is set to be controlled by Ignition Switch, Daytime Running
Light (Output 3) is turned ON with a delay of 5s once the Ignition Switch is turned ON. If
Head Light is turned ON the DRL are turned OFF immediately. The DRL is turned OFF with
a delay of 20s once the Ignition Switch is turned OFF.
Note: Disconnect Battery before doing any connection.

Testing Procedure Park Brake Alarm
1. Disconnect Battery before doing any connection.
2. Connect Park Brake switch to Combo 64 Park Brake input.*
3. Connect Door Switch to Combo 64 Door Switch input.
4. Ensure that the polarity of BOTH switch(s), and set the DIP switch setting accordingly.
5. Connect the Battery to the Combo 64.
6. Ensure that the vehicle will not move when the Park Brake is released. Ensure the Park
Brake is ON and the driver door is closed.
7. Release the Park Brake, no alarm should be heard.
8. Open driver door, alarm should be heard. Wait 5 seconds to see if the (optional)
external alarm is activated.
9. Close driver door, alarm(s) should still be heard.
10. Apply Park Brake, both alarm(s) should stop.
* In case Park Brake Indicator on the dash board lights up after connecting the Park Brake Switch
to the Combo 64 Input, installer should install a separate Park Brake Switch for connecting to
