 The Dei 520T BackUp battery provides added security to your car or truck or motorcycle by keeping the securty system active and alive even if your power source battery in your vehicle is disconnected by an intruder.  This backup battery is intended only to power the security system's control module and should not be used to power accessories that may have a large current draw.  All alarm accessories should be powered directly from the vehicle's battery.  Connect the backup battery as shown in the diagram.

RED WIRE (+) Constant 12V input.  Connect this wire to a fused source of constant 12 volts.  This can be either the main power source feed at the ignition switch or the (+) terminal at the battery.

BLACK WIRE(--) Chassis ground input.  Connect this wire to the vehicle chassis.  Use factory bolt if possible.

BLUE WIRE(--) Trigger output.  Connect this wire to the (--)instant trigger input of the sucurity system.  This wire will send a (--)signal if the vehicle's battery is disconnected, triggering the security system.

GRAY WIRE(+) 12V  Output.  Connect this wire to the (+) constant power 12V input wire on the alarm control module main harness.  DO NOT connect to the 12V in the vehicle.  This wire supplies power to the security system.

IMPORTANT!!!...This out is only capable of providing enough current to power-up the control module.  Any additional accessories or external relays must be powered by the vehicle's battery.  Always follow the guidelins when installing the 520T BackUp Battery.

1.  Due to electrical current limits, do not use the security systems on-board parking light relay for remote start applications.  Most DEI systems have an on-board light flash output polarity jumper that should be moved to the negative position to activate the after-market or factory out-board parking light relay.  For other manufacturer's alarms that have on-board relays, use an out-board relay for parking light flash.

2.  Do not use the 520T Backup Battery to support the parking light flash during remote start applications, as most parking light systems will require at least 5 amps of continous draw which exceeds the current output of the 520LT Backup Battry.

3.  Use the 520T to backup only the CPU of any security or convience system.  All other load use including power door locks, horn honk,  window automation, lighting systems, remote start systems, etc., should have their own fused power lead to a constant power wire designed for the required load.  All of the above optional devices exceed the current output capacity of the 520T Backup Battery.
