that door.
3. Connect 14 gauge wire from trailer running lights circuit to terminal block.
NOTE: The control unit is able to handle up to 15 amp loads.
4. Connect 14 gauge wire from positive side of trailer brake to brake output terminal
Note: The 12 Volt automotive battery must be grounded to trailer chassis.
5. Mount brake safety toggle switch. Both terminals on the brake safety toggle switch connect to two
terminals marked T/SW on the terminal block in the control box.
5a. If the brake safety toggle switch is left in the on position before towing siren will sound upon brake compression.
IMPORTANT: The brake safety toggle switch must be turned off before trailer is to be towed. This switch is used to prevent
accidental trailer brake activation while towing.
NOTE: If this switch is not installed, the alarm brake feature will not work.
6. Connect siren (red wire) to control module terminal block, connect (black wire) to trailer ground.
7. Connect 12 gauge wire from negative battery terminal to control module terminal block marked GND.
8. Connect 12 gauge wire from positive battery terminal to control terminal block 12V.
8a. Improper wiring of 12V positive or negative wire will damage unit.
9. “AUX” terminal: To be used for optional devices. This terminal is switched on/off upon arming and disarming process. It supplies
12V+. It will only handle up to 100 mA.
Testing
Close ALL doors and press the button or turn the key switch if you have the optional keypad refer to keypad instructions.
1. Trailer lights should flash once.
2. Alarm in now armed.
3. Open side door
a. Running lights are flashing.
b. Siren is sounding.
c. Brakes are engaged.
d. Optional Pager will sound.
e. Optional cellular dialer will send message.
f. Press button once or turn the key switch to disarm alarm.
g. Trailer lights will flash twice.
Repeat above sequence to test all doors.
The alarm will go off for 1 minute (siren will sound, lights will flash, brakes will lock.) If at the end of the minute if it still sees a trigger
it will continue for another minute and then go into nuisance prevention.
4. Accelerometer
The alarm circuit uses an accelerometer integrated circuit that allows the alarm to sense motion no matter how it is mounted.
When the alarm is armed, the trailer's position is saved in memory so that if the trailer is moved the alarm will be triggered.
Accelerometer Sensitivity
The sensitivity of the accelerometer may be reduced by removing jumper from P2 position. The accelerometer comes pre-
programmed in the most sensitive position.
