CHAPTER 3 INSTALLATION

This section describes the placement, mounting and electrical connectios required to install your alarm system. You need the following tools to complete the DIY installation:

Drill with assorted bits

Screwdrivers

  1. Mounting The Siren:
    1. Select a location under the hood for the siren. The location should be away from any sources of extreme heat and should let you install the siren point down to prevent the dust or moisture accumulation. For loudest operation, be sure the siren is located as unobstructed as possible.
    2. Place the siren at the chosen location, and use a pencil to mark the locations of the three mounting holes.
    3. Drill a 1/8 inch hole at the three locations marked in step(2). Be sure that you do not drill into a mechanical or electrical assembly.
    4. Secure the siren using the three self-tapping screws.
  2. Wiring Connection:

    There are nine lines (Named A-E) coming out of the rear cover of the Siren. They have to be connected in the proper way.

    1. Line A (Red)

      To be connected to the positive (+) terminal of the car battery via the fuse.

    2. Line  (Black)

      To be connected to the car body for grounding.

    3. Connector Ñ:

      To be connected to Harness Ñ after completion of wiring

      Cl (Blue):

      To be connected to positive terminal of the fan. If the fan goes to high, it disarms the system. When the fan returns to low, the system will automatically arm itself after the delayed time This line is optional and it's only useful for some European car which ignites the fan automatically when the car's engine is too hot. For other type of car, this line is not necessary to be connected. Most of chances are this line is not necessary to be connected.

      C2 (Yellow):

      To be connected to the external relay as a starter killer or an engine killer.

      Remark:
      1. The 3 lines of the external relay are to be installed as near as possible to the engine's start motor.
      2. For safety's sake, it is not recommended to connect C2 as an engine killer.
      3. The car's key switch includes the following slot positions: Lock, ACC, ON, START

      C3 (Orange):

      This is the positive trigger. You can optionally connect it to the positive door frame switch.

      C4 (Green):

      This line is the negative trigger. You can optionally connect it to the negative door frame switch and/or trunk pin switch, hood pin switch in parallel:

      Notes:

      You can use a voltmeter to determine the correct trigger type of your car doorframe switch. Please proceed as follows:

      1. Open the passenger-side door and locate the door frame switch.
      2. Connect the voltmeter between ground (the metal chassis ) and the frame switch.
      3. If the dome courtesy light is on, and the voltmeter reads zero volts, then the frame switch is a negative trigger type If the voltmeter reads +12 volts, then the frame switch is a positive trigger type.
    4. Wire Harness D

      You can optionally connect this wire to the LED socket and extend the wire to inside the car where it's easily seen from outside the car to have the warning away effect.

    5. Line E (Black)

      As the Receiving Antenna Wire, it is suggested to be left free.

    6. Grey Loop Wire

      When cut, the current sensing feature will be deactivated.

CHAPTER 4 OPERATION PROCEDURES

As soon as all the system components have been installed, you can start testing the system step by step as described in this chapter.

  1. Power On The System:

    Use the key switch to turn on the power of the alarm system (See Fig. 4.1) and a long chirp can be heard. Then the system is ready to use. Note that if the power lines are not connected properly, then turning on the "" '*ch will trigger the alarm immediately because the system sees it as a connection of the power.

  2. "ON/OFF" Testing:

    You can arm or disarm the System by pressing the "ON/OFF" button on the Remote Control Unit. Pressing this key will switch between ON and OFF alternately.

    1. Arms the System

      Before you arm the System, you have to close all the car doors, the hood/trunk and turn off the engine. When you press the "ON/OFF" button the first time you will hear a short bark from the Siren and the LED will light on, then the system enters into the "Armed State" right away. Now the System will guard your car against the intruders.

    2. Disarms the System:

      When you press the "ON/OFF " button again, you will hear a long bark. The LED will become off and the System will enter the "Disarmed State" immediately.

    When the System is sounding the siren, you can press the "ON'/OFF' button to stop the siren and disarm the system.

  3. "CAR FINDER" Testing:

    Press the "CAR FINDER" key once and you will hear siren sound for about 3 seconds so you can find your car easier. If you firmly press without releasing it, then you will hear a continuous sound.

    Note :

    The "CAR FINDER" key works no matter in the "Armed State" or in the "Disarmed State" and it will not alter the current state.

  4. Dome Light Switch Setting:

    You must set the dome light switch to "DOOR" position so that if any door is opened then the dome light will be lit on immediately and a sudden voltage drop on the main power system will thus be detected by the "Voltage Detector" of the System immediately.

  5. Vibration & Voltage Detection:

    1. By "Vibration Detection" Sensor

      If the car body or the glass is bumped or hit, it can be detected by "Vibration Detection" Sensor and the System will sound the siren for 30 seconds and then stop, but the system will still remain in the "Armed State".

      Note:

      The vibration sensitivity is adjustable by turning the sensor screw clockwise (more sensitive) or counter-clockwise (less sensitive).

    2. By "Voltage Drop Detection" Sensor

      When the door is opened, the dome light will be lit on if the dome lighr switch is set to "DOOR" position. When the trunk is opened, the trunk light (if any) will be lit on. In either situation, it will cause a voltage drop on the car's battery and will be detected by the "Voltage Detection" Sensor and the system will sound the siren ear-piercingly for 30 seconds.

  6. Positive/Negative Trigger Detection:

    Normally this refers to the door or pin switch trigger. When the door is opened, then it triggers the alarm immediately.

  7. LED:

    It lights on while the system is in the "Armed State" and becomes off while the system is in the "Disarmed State".

  8. Six-tone Siren:

    It is adjustable as long as you remove the cover first. The factory's original setting is pin 6 ON (Jumper is closed). You can set any configuration except the pne with all offs.

  9. Warnings On Using The Alarm System:

    If you have not used your'car for a long time, be sure to start your car engine at least once for every 20 days or less The purpose is to recharge and maintain the car's battery at a working level.

CHAPTER 5 BATTERY REPLACEMENT

5.1 For The Remote Control Unit
  1. When you find that the remote control distance of the Remote Control Unit becomes shorter, check the causes. If it is the problem of the battery, then the battery has to be replaced.
  2. Unscrew the back panel of the Remote Control Unit with cross point screwdriver.
  3. Replace the 12V alkaline battery according to the polarity requirements.
  4. Press the "ON/OFF" button and check if the "LED" lights on. If it doesn't, check if the polarity or the connection is OK.
  5. If the "LED" can light on for the button pressing, then recover the panel and screw it back.
5.2 For The Backup Siren

If the disconnection of the power line won't trigger the alarm, then the 9V battery may have to be changed as follows:

  1. Turn off the key switch.
  2. Unscrew the cover of the siren unit.
  3. Replace the 9V battery according to the polarity requirement.
  4. Turn on the key switch to see if it triggers the siren. If yes, then turn off the key switch, put back the cover and turn on the key switch again.
