The TR-7 is a universal trigger output module that has various user

programmable features combined into one unit. The user programmable

features are stored in non volatile memory. When triggered, the TR-7

can turn on the outputs as a pulsed, latched or a timed output. There

are two inputs, the GREEN wire is a positive input that senses voltages

as low as 0.8 volts and the BROWN wire is a negative input, both are

tied together internally which is, essentially, ONE trigger input.

There are 3 separate outputs, the BLUE wire is a positive 12 volt

output which has a maximum current rating of 2 amps. The WHITE

and ORANGE wires are negative outputs which have a maximum of

current rating of 150 milliamps. The timed output is user adjustable and

can be programmed up to 4 minutes and 15 seconds. What makes the

TR-7 unique is that it does not use a potentiometer to adjust the timer. The timer is set by programming TR-7 minutes and seconds with

a number. The time saved is accurate to the second +7% - 8%.

#1: Low voltage trigger. Supplies a 12 volt remote output for an aftermarket

ampliﬁer when used with a stock head unit that does not have a remote

output. Use the TR-7 to supply a 12 volt output from a 5 volt remote

source, like from Ford radios. Use on some vehicles that have a

negative antenna output and convert to a positive output.

#2: Alpine video bypass. This will automatically bypass Alpine’s ﬂip out monitor

video procedure. WARNING! It is dangerous (and illegal in most

states) for the driver to watch the TV/Video monitor while driving

the vehicle. The driver may be distracted from looking ahead and

an accident could occur. Install the TR-7 only in RV and Marine

applications where there is no parking/hand brake to interface to.

Do not install the TR-7 where the driver may be able to view the

monitor when driving.

#3: Latch and unlatch output from a pulsed input. Turn on headlights, neon

lights or radio from an alarm with a momentary output or from a

momentary switch.

#4: Double pulse output. Pulses outputs twice when trigger from a constant or

pulsed signal. Use for alarm applications where the unlock wire needs 2

pulses to unlock all doors.

#5: Closed loop circuit. Good for monitoring trailers on hitches by triggering an

aftermarket alarm if the trailer is disconnected from the vehicles hitch.

Also monitors stereo equipment in vehicles.

#6: Pulse extender/Delayed turnoff. Upon a constant or pulsed trigger, the

TR-7 will turn on the outputs. As soon as the trigger is disconnected,

turned off or at the end of a pulse, the timer will count up to the number

of seconds recorded, at which time the outputs will turn off. Good for

turning on headlights at night for convenience. Extend alarms output

from 1 second to 3 seconds for Mercedes vacuum door locks. (rev.2)

#7: Horn honking output. On older, aftermarket alarms, it may have been

difﬁcult to disarm the alarm with the RF remote when the horn was

honking. This will give you a 2 second delay between honks, allowing

you to disarm the alarm. Unique horn honking to distinguish your

vehicle from others. Program between 1 and 5 honks before the 2

second delay.

OFF-ON

Programming switch must be turned off

after the TR-7 is programmed!

#8: Linear Actuator Controller. Open/close ampliﬁer racks from a momentary

source like from a alarm’s negative output. Sequence is : Start, Stop,

Reverse, Stop.

#9: Door lock Pulse generator. Good for automatically locking and unlocking

door locks when ignition is turned on and off.

#10: Channel Splitter. Split 1 channel from an alarm to 2 outputs. Both outputs

are user programmable for pulse, latched or timed output.

#11: Pulses to constant output. Counts a number of user programmable

pulses within a user programmed time to turn on the outputs. Good for

triggering Vehicle tracking devices that need a constant trigger but the

factory alarm only has a pulsed output when triggered like ﬂashing lights

or horn honking. Keeps factory alarm from triggering Vehicle tracking

device when arming or disarming.

#12: 3 timers in 1. Upon a constant trigger, all 3 outputs are user programmable

to delay before turning on outputs or turning on instantly then delay

before turning off outputs. Good for situations where you need more

than 1 timer but on a different timer period, without having multiple

modules.

#13: Pulses to latch/unlatch outputs. Upon a number of pulses within a user

programmable time, the outputs will latch. Upon a number of pulses

within a user programmable time the second time, the outputs will

unlatch. You may program how many pulses to latch and unlatch. Use to

turn on aftermarket driving lights by using existing parking light switch.

#14: Pulses to pulse output. Upon number of pulses within a user programmable

time, the outputs will pulse. Example, if you programmed to see 4

pulses, for every 4 pulses the TR-7 sees within a 5 second time period,

the outputs will pulse once.

#15: Pulses to timed output. Upon a number of pulses within 5 seconds, the

outputs will turn on and delay for the amount of programmed time, then

the outputs will turn off.

#16: Latching outputs #2. Good for turning on 2 sets of driving lights with one

momentary switch. 1st pulse will latch one wire. 2nd pulse will unlatch

ﬁrst wire and latch second wire. 3rd pulse will latch both wires. 4th pulse

turns off both wires.

The basic descriptions below are the features that can be done with the TR-7. Each feature is assigned a Feature#. Please make note of which Feature# you are

going to use. Other unique projects/installs can also be derived from the TR-7, so PAC leaves it to the installer’s imagination to experiment with these features.

#9: Connect the GREEN wire to a true ignition wire of the vehicle. Connect the WHITE

wire to the lock relay and the ORANGE to the unlock relay. When the ignition is turned

on, the WHITE wire will pulse once after a 5 second delay. When the ignition is turned

off, the ORANGE wire will pulse once. The ORANGE wire is user programmable not

to pulse when the trigger is disconnected.

#10: Connect the BROWN wire to the alarm’s negative output. Connect the WHITE wire

to the ﬁrst device being controlled and the ORANGE wire to the second device being

controlled. Use relays if the devices draw more than 150 milliamps. After a single

pulse from the alarm within 3 seconds, the WHITE wire will activate. After two pulses

within 3 seconds, the ORANGE wire will activate. Each wire is user programmable

for a pulse, latch or a timed output. Please note that if any one of the two wires are

programmed for a timer output, the TR-7 will not respond until the timer is ﬁnished.

#11: Connect the GREEN or BROWN wire to the factory alarm’s ﬂashing light or horn

output. Connect the BLUE or WHITE wire to the vehicle tracking device trigger input.

You can program the amount of pulses the TR-7 sees within a user programmable

number of seconds to trigger the vehicle tracking device. Example; if the factory alarm

ﬂashes or honks the horn a maximum of 2 times when arming or disarming, then you

may program the TR-7 to see a minimum of 4 pulses within a 5 second period to

trigger the TR-7 which will turn on the BLUE and WHITE wire. As long as the pulses

continue, the TR-7 BLUE or WHITE wire will stay on.

#12: Connect the BROWN or GREEN wire to a source that stays constant when turned

on. Connect the BLUE, WHITE and ORANGE wire to the devices being controlled.

Both outputs are user programmable to delay before turning on the outputs or

programmable to turn on outputs instantly, then delaying before turning off. You do

not need to use all the outputs, but during programming you do need to program all

features and timers before you can automatically exit programming.

#13: Connect the GREEN or BROWN wire to a momentary or pulsed source. Connect the

BLUE or WHITE wire to a device being controlled. Upon seeing a number of pulses

within a number of seconds the ﬁrst time, the outputs will latch. After seeing a number

of pulses within a number of seconds the second time, the outputs will unlatch. You

may program how many pulses the TR-7 needs to see to latch and unlatch the

outputs. turn on and off your parking lights 4 times within 5 seconds to turn Example;

on aftermarket lights. Turn on and off 3 times within 5 seconds to turn the aftermarket

lights off.

#14: Connect the GREEN or BROWN wire to a pulsed output source. Connect the BLUE or

WHITE wire to a device being controlled. Upon seeing a user programmable number

of pulses within a user programmable number of seconds, the BLUE and WHITE

outputs will pulse once. Example, if you programmed the TR-7 to see 4 pulses within

7 seconds, then for every 4 pulses the TR-7 sees within 7 seconds, the outputs will

pulse once.

#15: Connect the GREEN or BROWN wire to a pulsed output source. Connect the BLUE

or WHITE wire to a device being controlled. Upon a user programmable number

of pulses the TR-7 sees within 5 (non adjustable) seconds, the BLUE and WHITE

outputs will turn on and delay for a user programmable time, then the outputs will turn

off.

#16: Connect the BROWN or GREEN wire to a momentary source. Connect the BLUE or

WHITE wire to the device being controlled. On the ﬁrst pulse the TR-7 receives, the

WHITE wire will latch on. On the second pulse the WHITE wire will unlatch and the

ORANGE wire will latch on. On the third pulse, the WHITE and ORANGE wires will

latch on. On the fourth pulse both the WHITE and ORANGE wire will turn off.

#1: On a constant trigger, both the BLUE and WHITE wire will activate after a one second

delay. If you are using the TR-7 to turn on an ampliﬁer, you can connect the GREEN

wire to any (+) speaker wire lead and the BLUE wire to the ampliﬁer’s remote input.

If you need to invert a negative to a positive output, connect the BROWN wire to the

source and the BLUE wire to the device that needs to see a positive signal to activate.

The BLUE wire can connect directly to 1 to 4 devices that have a remote trigger input.

If the total current draw of the devices exceed 2 amps, use a relay to supply 12 volts

at a higher current.

#2: This will automatically bypass Alpine’s video procedure. After programming (detailed

programming on page 3), connect the GREEN wire to the Alpine’s remote wire, the

BLUE wire to the Alpine’s foot brake input wire, the WHITE wire to the Alpine’s parking

brake input wire. In this conﬁguration, relays are not needed. Do not connect any other

sources to the WHITE or BLUE wires of the TR-7. Connect the RED wire to vehicle’s

accessory 12v. Note: This feature is factory set. Keep switch to off position and

wire according to above. No programming is neccessary unless changed.

WARNING! It is dangerous (and illegal in most states) for the driver to watch the TV/Video

monitor while driving the vehicle. The driver may be distracted from looking ahead and an

accident could occur. Install the TR-7 only in RV and Marine applications where there is no

parking/hand brake to interface to. Do not install the TR-7 where the driver may be able to

view the monitor when driving.

#3: Connect the BROWN or GREEN wire to a momentary source, like from a switch or

alarm’s output. When triggered, the BLUE and WHITE wire will turn on and stay on.

When triggered a second time, the BLUE and WHITE wires will turn off. Use the BLUE

or WHITE wire to activate a relay to turn on lights, neon, or any other source that

draws high current.

#4: Connect the BROWN wire to the alarm’s unlock output and connect the BLUE wire or

WHITE wire to the unlock wire of the vehicle that needs to see 2 pulses to unlock all

doors.

#5: Extend the BROWN wire and connect to the chassis of the trailer or the back of stereo

in such a way that the BROWN wire must be cut or disconnected from the chassis, if

a theft is in progress. The BROWN wire must be connected to a good chassis source

so that it will not false trigger. Connect the BLUE or WHITE wire to an alarm or other

alarming device trigger input. You may program a delayed time before the outputs will

turn on when the BROWN wire is disconnect from the chassis.

#6: Connect the BROWN or GREEN wire to a pulsed or constant source. Connect the

BLUE or WHITE wire to the device that you want to activate for a time period. You may

program a delayed off time. The delay will not start until the end of the pulse or when

the constant trigger is off.

#7: Connect the BROWN or GREEN wire to the siren output of the alarm. Connect the

BLUE or WHITE wire to a relay that will supply a positive or negative output to the horn

wire. When triggered, the TR-7 will delay 2 seconds before honking the horn.

#8: Although this is not a full Linear Actuator Controller (does not have a brake wire),

the TR-7 will brake correctly when used with limit switches. If wired according to the

diagram on the diagram page, the linear actuator will function and work correctly.

Connect the BROWN or GREEN wire to a momentary source. When pulsed the ﬁrst

time the WHITE wire will latch on, then 1.5

seconds later the BLUE wire will latch on

(this will allow time for the limit switches to turn off) . On a second pulse both the BLUE

and WHITE wire will turn off. On a 3rd pulse the ORANGE wire will latch on, then 1

second later the BLUE wire will latch on.
