Modular car alarm CA-02 Fox 

1/2 

MHJ51103 

The CA-02 Fox car alarm is a simple modular car alarm. It is to be installed 

in the interior of cars with 12V and a negative ground.  

The alarm can be operated 

by

 

the

 

ignition key, a hidden switch or by the 

original remote control for central locking.  

The status of the car alarm is indicated by an 

LED indicator

.  

The built-in vibration detector has two levels of sensitivity and a digital 

filter which provides a high immunity to false alarms. It responds with either 
a warning or an alarm trigger or both. The warning mode causes a short siren 
chirp in the case of vibration detector activation. In alarm mode the alarm is 
triggered if a vibration is followed by another one within 15 sec. If both modes 
are activated then the first vibration will cause a short siren chirp and the other 
vibration (within 15 sec.) will trigger the alarm. 

A built-in current sensor will trigger the alarm if electrical equipment is 

switched ON while the CA-02 is armed. The current sensor will be activated 
10 minutes after arming. This prevents the cooling fan from triggering the 
alarm. The sensor can be disabled to allow the use of additional equipment 
(independent heating, fridge etc.) 

The functions of the inputs, the ignition key and the additional detectors 

depend on the settings used (see setting table below). The alarm is triggered if 
any of the alarm inputs is activated while the alarm is armed. The siren output is 
activated for 30 sec. A siren can also confirm arming/disarming by short chirps. 
A programmable output can control the immobilization relay or activate 
additional detectors while the car is armed. A VALET push button can be used 
for emergency disarming or for setting the optional alarm functions according to 
the individual customer’s needs.

Terminal board description 

 

Installation

 

 

GND

 

black 

– connect to the original grounding in the car.

 

ULK/AL3 white-blue

 – input to control the alarm by the original central 

locking. It reacts to connection or disconnection from ground (depending on 
setting). The input can be connected directly onto the wire of the servomotor or 
to the signal wire called “unlock” on the central locking unit. If the alarm is 
controlled by an ignition key (KEY) it will function as a delayed alarm input.

 

It is 

not suitable for connection the hood (bonnet) contact!   

LCK/AL2

 

white-black 

– input to control the alarm by the original central 

locking. It reacts to connection or disconnection from ground (depending on 
the setting). The input can be connected directly onto the wire of the 
servomotor or to the signal wire called “lock” on the central locking unit. If the 
alarm is controlled by an ignition key (KEY) it will function as an instant alarm 
input.

 

It is not suitable for connection the hood (bonnet) contact! 

DOOR

 

grey 

- door switch

 

input. It reacts to connection or disconnection from 

ground 

LED indicator black-white

 – install it on a visible spot on the dashboard.  

Connect the other end of this lead to GND. 

PGM 

Output blue-white 

- programmable output that can control the 

immobilization relay or activate additional detectors while the car is armed. The 
maximum load is 0.2A 

switching to GND

.  

The function of PGM depends on the setting of parameter 4 (see the 
setting table below): 

power supply for an additional detector – the output is activated 
when the alarm is armed 

immobilization relay activation - copies the status of the ignition 
key when the car alarm is disarmed. 

SIR

 

yellow 

– siren output (max. 1,2 A) 

switching to GND

+12V

 

red 

– connect directly to the battery. Check that the installation is done 

properly before powering up! Protected by a built-in fuse. 

BLK

 

yellow-white 

– this input is activated by +12V according to its setting to 

confirm locking/unlocking of the car by the original remote control, is activated 
by the confirmation signal from the turn lights (flashers) or it blocks the current 
sensor and the AL3 input.  

KEY

 

blue 

– input (+12V). Be sure, that there is +12V present while the key is 

on while starting the engine. 

AL1

 

white 

– an alarm input with an instant reaction. It reacts to connection or 

disconnection from ground.  

VALET green

 – a push button used for emergency disarming, memory 

reading and setting the selectable functions.  

NC

 – not used

 

The LED indicator 

 

The LED indicator shows the status of the car alarm: 

 

OFF

 

  

 

   - disarmed 

ON 

 

 

   - exit delay 

Regular slow flashing  

   

- armed 

Regular fast flashing    

   

- entry delay 

 

If you can hear three siren chirps while disarming, then an alarm had 

been triggered during the last arming. The cause of the alarm is signaled 
by the LED indicator while switching the ignition key on. The number of 
flashes indicates the alarm input: 

 

1   flash  

   - DOOR 

2   flashes – 

AL1 

3   flashes

 - 

current sensor

 

4   flashes 

vibration sensor

 

 

5   flashes

 – ignition key 

(not when the alarm is controlled by KEY)  

6   flashes

 – AL2 

7   flashes

 – AL3

 

(AL2, AL3 – not when the alarm is controlled by the central locking)

 

 

It is also possible to determine the cause of the last two alarms. With 

the ignition key on, press the VALET button the LED will flash repeatedly 
(10 times) indicating the cause of last alarm. If the VALET button is 
pressed once again during indication, the cause of the second-to last 
alarm will be indicated (10 times). You can stop indication by switching the 
ignition key off.  

 

 

Maintenance

 

 

The device does not require any special maintenance. We recommend 

you to check the function of the door, the hood switches and additional 
detectors regularly.  

 

Setting 

 

Some parameters can be changed in the setting mode according to the 

table below.   

To enter the setting mode:  

1.  Press and hold the VALET button, for between 4 to 6 seconds, and switch 

the ignition key on. Entering setting mode is confirmed by two siren chirps.  

2. Parameter status is indicated by the LED and can be changed by switching 

the ignition key off for less than 3 sec. 

3. To select the next parameter, briefly press the VALET button. Each setting 

parameter is confirmed by a corresponding number of siren chirps. 

4.  To exit setting mode without saving changes, switch the ignition key off for 

longer than 3 s (two siren chirps will be heard).  

5. To exit and save the changes go through all the parameters. A long siren 

chirp acts as confirmation. 

 

If parameter 15 is set to 

yes, 

then when programming is finished and the 

alarm has been disarmed for the first time the interval between the 
unlocking signal (ULK) and the flashing of the turn lights (BLK) is read by 
the car alarm. Further disarming will only be possible if the interval 
between the ULC and BLK signals is the same (tol/- 200ms). 

 

Warning!!!  If parameter 15 is set to 
yes and the turning lights are 
flashing when the car is armed, it 
will not be possible to disarm the 
alarm by remote central locking.
