Car Alarm CA-10 „REX“

 installation 

manual 

 

The CA-10 is a compact remote controlled car alarm with a building block 

architecture. It can be easily extended with CR-11A modules to be tailored to 
particular installation requirements (central locking control, immobilization 
etc.). This remotely controlled car alarm can have a maximum of two addi-
tional RC-4x remote controllers added to the one provided. Remote control 
signals are protected by a hopping code and an Anti-scan feature. 

The CA-10 provides additional features for the ease and convenience of the 

user (dome light control, car locator feature, indication of alarm memory, 
rearm function, etc.).  

 

Installation

 

 

The installation  of the CA-10 Rex is not complicated. However, professional 

installation is highly recommended to ensure 100% functionality. 

The main unit of the car alarm should be installed in the engine or passenger  

compartment.  Disconnect the car battery before starting installation. No one  
should be inside a car equipped with airbags while the battery is being connected 
or disconnected. Refer to the car owners' manual before disconnecting the battery. 
If you drill a hole in the car, be sure to check the intended hole location  before 
drilling to prevent damage to the car. 

Screw the metal bracket of the main unit firmly to the car body. It is critical that 

the unit is firmly secured to assure proper function of the vibration sensor. Do not 
place the unit close to any  hot objects (exhaust pipe, radiator etc.).  

 

WIRING

 - route the wires of the car alarm along  with the pre-existing electrical 

harness of the car. Check each connection made to ensure that it is firm and 
properly insulated. Use only a real crimping tool to make needed connections:  

 

RED = power +12V

 - connect it to a direct line from the positive battery terminal  

 

BLACK = grounding

 - connect it to the original GND point in the car. 

 

BLUE = ignition key 

- to the ignition key switch (+12V when ignition is ON). 

 

GRAY = door switches input

 - is a negative alarm trigger input. Connect it to  

the door switch which should be installed on every door. This input also functions 
as the dome light control output (the max. load of the light is 10W).

 

 

 

WHITE = AL trigger input

 - is activated when connected to the ground (or 

when disconnected from the ground - selectable). The type of reaction (Alarm or 
Warning) can be selected for this input. An additional sensor can be connected 
to this wire (for example a hood switch etc.). 

 

GREEN = LED indicator

 - drill a 6.5mm (4/16") hole in the dashboard and 

install the LED with the attached plastic bracket. 

 

YELLOW = VALET switch

 - install it in a hidden location in the car  

After routing wires from the green LED & Valet, insert their ends, equipped 
with metal contacts, into the corresponding positions on  the main unit ‘s 
connector (see  color marks on the connector housing).     

A short gray wire going directly from the CA-10 unit is a remote control antenna. 

Location of this antenna effects remote control working range.

 

 

Testing of the installed car alarm

 

Complete and check all wiring before switching on the power. After switching 

on the power, check all basic functions of the car alarm (see operation). Fix new 
wires to the original wireharness of the car. 

This is the end of basic installation.  

 

Adding of a new remote control

 

There is one remote control in provided with the set. The car alarm can be 

operated with by  maximum of three RC-4x remote controllers. To add an 
additional remote control: 

  switch on the ignition key when the car alarm is disarmed and press the 

hidden VALET button five times, consecutively.   

  the siren will sound two signals and the alarm is now in  a learning mode 

  activate all remote controls (one by one, button 

)  that you want the car 

alarm to accept. 

  if you activate only one controller in the learning mode, you will be able to 

control the car alarm only with this one controller 

  to close the learning mode, switch off the ignition key  

 

Setting mode

 

Optional functions can be modified the following way:  

  press VALET button when the car alarm is disarmed and hold it pressed 

  after 5 seconds or more, switch on the ignition key. The siren will indicate open-

ing of  the setting mode, and you may now release the Vallet button. 

  now you are in row no. 1 of the following table. Setting of the parameters is 

indicated by the LED. Bold printed parameters are factory default settings.  

  settings can be changed by pressing a remote control button, Each short press-

ing will change the parameter (on - off - on - off - etc.).  

  to select next parameter (next row in the table), press the VALET button quickly. 

The number of beeps from the siren will correspond with the parameter number.  

  Pressing the VALET button on parameter no. 13 will store data to the memory 

and the setting mode will be exited (confirmed by a long signal from the siren).  

Note: If you switch the ignition key off before the setting mode is com-

pleted, the setting mode will be terminated and no changes will be stored. 
Removing power from the car alarm will not change stored data.
