The 452T is a versatile unit that can meet door loc k and other unique installation needs. It can be used as a door loc k pulse
generator to convert a positive or negative latching input to door lock and unlock pulses. The 452T can provide either 200mA
(-) or 200mA (+) pulses for door locks, making it possible to control any relay driven factory lock system without any additional
parts. Common applications include adding door locks to a unit that has a ground-when-armed output, or generating pulses
for ignition controlled door locks.
The 452T can also generate two separate pulses from a single pulse input.Some newer vehicles require two pulses to unlock
the doors such as: newer Nissan vehicles, Infiniti vehicles, and Volkswagen vehicles.
452T
RED
(+) 12V constant power input: Connect this wire to a fused source of constant (+) 12V.
BLACK
(-) chassis ground: Connect this wire to a paint free surf ace on the vehicle chassis.
ORANGE
(-) activation input: If the 452T is being used to generate lock and unlock pulses, connect this wire to the ground-
when-armed output of the secur ity system. If the 452T is being used to create a doub le (-) pulse, connect the ORANGE
wire to the (-) unlock output from the secur ity system.
VIOLET
(+) activation input: If the 452T is being used to generate lock and unlock pulses for ignition controlled door locks,
connect this wire to a source of (+) 12V s witched ignition in the v ehicle. If the 452T is being used to create a doub le (+)
pulse, connect the VIOLET wire to the (+) unlock output from the security system.
IMPORTANT: The ORANGE and VIOLET inputs cannot be used at the same time. Damage to the module will result.
