INSTALLATION GUIDE FOR:
KEYLESS ENTRY
CHANNEL CREATOR
WITH ADJUSTABLE TIMER
AS-9501a
Printed In Taiwan
Form No. 128-4808C
INTRODUCTION:
The AS-9501a is a transistorized controlled "Keyless Entry Channel Creator" with an adjustable timed output of 0.8 to 60
seconds. This versatile Keyless Controlled unit will allow the safe operation of any device that is connected to its output.
Some of the more popular circuits that may be connected to this unit are: Remote Start, Power window roll up, Power
sunroof close, etc. The unique feature of this unit is that a series of Remote Keyless Entry Inputs will provide an output, i.e..
Lock, unlock, lock within 4 seconds in a two step factory configuration. This is necessary to prevent the connected device
from accidently being activated by the in vehicle door lock switch. If this safety feature is not required or desired, than the
unit can be set to operate from a single input.

POSITIVE OR NEGATIVE LOCK INPUT SELECTION : DIP SWITCH # 1
This unit can be programmed to accept either positive or negative lock input signals. This allows for proper installation into
vehicles using 3 wire ground, 3 wire positive, and 5 wire alternating door lock systems.
DIP SWITCH #1: When this switch is selected to the on position, the unit will accept a positive trigger on the Orange Door
Lock input wire. When this switch is selected to the off position, this wire will accept a negative trigger input.
1 OR 2 WIRE UNLOCK INPUT SELECTION : DIP SWITCH # 2
This unit can be programmed for single step, 'one wire' unlock or two-step, 'two wire' unlock configuration.
Many OEM keyless entry systems use on-board door unlock relays, which usually results in the ability to unlock driver's door
only and then unlock all doors.
DIP SWITCH #2: When this switch is selected to the on position, the control circuit will operate in a two step, two wire
configuration. This is the controlled output operation mode. When this switch is selected to the off position, the control
circuit will operate in a single step, one wire configuration mode.
CONFIGURATION: Two Step Factory Keyless Entry upgrade with +12 volt door locks.
THIS INSTALLATION WILL REQUIRE THAT THE DIP SWITCHES BE SET TO 1 ON, 2 ON.
WIRING:
Red: +12 volt Battery Source. Connect this wire to a + 12 volt constant battery source.
Black: Chassis Ground. Connect this wire to a clean solid metal chassis ground source in the vehicle.
Orange: Connect this wire to the lock control wire found at the vehicle driver's door motor. This is the wire that gets +12
volts when the door lock button on the factory keyless entry remote is depressed.
Green: Connect this wire to the unlock control wire found at the drivers door motor. This is the wire that gets +12 volts when
the unlock button on the factory keyless entry remote transmitter is depressed the first time.
Blue: Connect this wire to the second unlock control wire found at any door but the driver's door. This is the wire that gets
+12 volts when the unlock button on the factory remote transmitter is depressed two times.
Note: This wire will not have +12 volts when the unlock button on the factory transmitter is depressed only one time.
Light Green Wire: This wire will provide a low current ground signal when the factory keyless entry transmitter buttons are
sequentially pressed in a Lock, Unlock, Lock pattern within 4 seconds. This wire will be connected to the trigger input of the
device you wish to control. This output is capable of 500 mA maximum current. If the device you are connecting this wire
to requires more than 500mA to operate, then a relay will be required. SEE FIG.# 1 for relay wiring configuration.
The duration of the ground signal on the Light Green Wire is fully adjustable from a minimum of 0.8 seconds (800ms), to a
maximum of 60 seconds. This adjustment is controlled by the potentiometer located through the side of the module's case.
Turning this adjustment clockwise will increase the output duration. Turning the adjustment counter clockwise will decrease
the output duration.
CAUTION: This unit's potentiometer is capable of 180° rotation. DO NOT overturn this adjuster or damage will occur.
Testing The Installation:
In this configuration, to test your installation, press the lock, unlock, then lock buttons on the factory transmitter within a 4
seconds time period. The accessory device should activate. Now enter the vehicle and press the in vehicle door lock switch
in the same sequential pattern and be certain that the accessory device does not respond.
