CA-340 modular car alarm 1/4 VAV50204

Car alarm CA-340 “Nestor” functions, controls

The CA-340 car alarm is intended for installation inside a vehicle with a 12 or 24V

power supply and negative ground. It is protected against the reversal of poles and

overvoltage, the activation inputs are protected against short circuit and voltage

induction.

Car alarm function overview

 A built-in shock detector with adjustable sensitivity controlled with a trimmer

inside the unit. Its activation can trigger a warning (1s siren chirp), trigger an

alarm or do both. If an alarm function is set, the unit uses a filter eliminating

accidental shocks (e.g. caused by a heavy vehicle passing by …). The alarm

is triggered only when the first shock is followed by another within 15 seconds.

If both the siren and the alarm are set, the first shock triggers a short siren

chirp and the second shock (within 15 s) triggers the alarm.

 A voltage drop detector registers sudden voltage drops caused by an

appliance which switches on when the alarm is armed (protection against a

mechanical breach of the central locking system). The detector is blocked for

20 minutes after arming (allows the radiator cooling fan to wind down). You

can also program it to remain switched off permanently if you use independent

appliances in the car (heater, refrigerator).

 The car alarm is equipped with several contact sensors, whose number

depends on how the alarm is connected (see below).

 Up to 8 JA-8x wireless detectors can be enrolled to the car alarm. These

can be used to detect motion inside the vehicle or the breaking of windows or

to guard the garage in which the vehicle is parked.

 A programmable output which can trigger the power supply to auxiliary

detectors (microwave, tilt) that are activated when the alarm is armed or it can

provide a signal for the controlling of a CR-11A (AUX) module.

 The immobiliser circuit can be used to immobilize the ignition, the fuel pump

or the ignition circuit. When the AUTOIMO function is active, the immobiliser is

activated automatically if the ignition key is switched off for more than 5

minutes. The AUTOIMO can be switched off by a remote control button.

 When an alarm is triggered, a siren is activated for 30s. When the alarm is

terminated in a regular way, the siren is switched off immediately.

 The siren can also be used for the acoustic confirmation of arming and

disarming (optional parameter). For other functions, see Acoustic signaling.

 When you leave your vehicle in a car servicing company for maintenance,

the AUTOIMO function and the acoustic signaling can easily be temporarily

disabled.

 Optical signaling of arming, disarming and alarms. The car alarm can

control the direction indicators (flashers) in three optional modes.

 Boot opening. When the alarm is armed, you can use a remote control to

open the car boot if its mechanism allows it. (The BLK output function must be

set to control the boot)

 PANIC is a function which allows triggering a siren with a remote control both

in an armed and an unarmed state (by pressing both buttons at the same

time). It can also help you find your vehicle quickly in a crowded car park.

 The car alarm is equipped with a Valet button for emergency disarming. The

button can also serve for the setting of optional parameters.

 The information concerning operating status of the alarm is signaled with an

LED.

 The car alarm settings and parameters can be changed easily using the

CA-340PRG wireless module connected to a computer.

Car alarm controls

The car alarm can be armed by locking the vehicle with the original remote

control or by pressing the

key on the RC-8x remote control (depending on the

means of connection).

Partial setting. When the setting key is pressed repeatedly during the exit

delay (20s after the alarm setting) the shock and voltage drop detectors and

wireless detectors guarding the inside of the vehicle are disabled. NOTE: this

function is not available when the car alarm is connected for controlling with the

original remote control without using a CAN-Bus (= AL1 input is set to confirm

arming and disarming)

The car alarm can be disarmed by unlocking the vehicle with the original

remote control or by pressing the key on the RC-8x remote control (depending

on the means of connection).

Rearming function If the car alarm is unarmed and no sensor is activated

within one minute (no one gets into the car), the alarm is armed again. If the alarm

controls the central locking system, the vehicle is locked simultaneously. This

function can be set by parameter 2 (REARM).

Boot opening. The car booth can be opened by pressing both remote control

buttons (the availability of this function depends on the means of installation).

Alarm

When armed, the car alarm checks the DOOR contact switches, INP1, INP2,

INP3 sensors where boot, bonnet or other detectors can be connected and

manipulation with the ignition key. It also reacts to the activation of the integrated

shock detector, voltage drop and enrolled wireless detectors. The wireless detectors

can be set to a 20s entrance delay (see the detector manual). If any of the alarm

sensors are activated in the period of guarding, a 30s alarm is triggered. When the

alarm has finished, the car alarm remains active.

 If the car alarm is controlled with original remote controls, the currently

active alarm can be terminated by unlocking the vehicle using the remote

control. The car alarm is concurrently disarmed.

 When the car alarm is controlled with an RC-8x remote control, pressing

the

keys can terminate the currently active alarm. Pressing the

key again disarms the alarm.

Emergency disarming – if the remote control gets lost or is faulty, the car

alarm can be disarmed by pressing the hidden Valet button as follows:

Open the car doors (triggers an alarm), switch on the ignition key and press the

Valet button. The emergency disarming can be disabled (parameter 4).

LED visual signaling

The LED indicates the alarm status as follows:

the LED is off - the car alarm is unarmed

permanently lit - exit delay in progress

regular short flashes - the car alarm is armed

rapid flashing - entrance delay in progress

regular short fading - AUTOIMO function activated

When the ignition key is switched on, the LED indicates the number of enrolled

RC-8x controllers.

Three alarm chirps during unarming indicate that there has been an alarm

since the last setting. When you turn on the ignition key, the LED then indicates

the cause of the alarm. The signaling is repeated 5 times. The number of flashes

indicates the sensor which triggered the alarm:

1 flash - the door sensor (DOOR) was activated

2 flashes - the INP1 sensor was activated

3 flashes - the INP2 sensor was activated

4 flashes - the INP3 sensor was activated

5 flashes – the voltage drop sensor (an appliance was switched on)

6 flashes – shock detector alarm

7 flashes – the ignition key was switched on in an armed state

1 to 8 fadings – wireless detector (according to the order in which it is enrolled)

The cause of the last two alarms can be viewed retroactively. If you press the

Valet button when the ignition key is on, the LED indicates the cause of the last

alarm 10 times successively. If you press the Valet button again during the

signaling, the cause of the previous alarm is also shown ten times. The indication

is terminated when the ignition key is switched off.

Acoustic signaling

Setting: 1 chirp * Partial arming: two quick chirps

Unarming: 2 chirps * Unarming after an alarm: 3 chirps

* can be disabled by setting partial acoustic signaling

Fault signaling:

 When armed, the car alarm tests the sensors for approx. 6s. If any of the

sensors is activated during this period of time (e.g. due to an improperly closed

door) it is signaled with 4 quick chirps. The alarm is armed but the sensor

which remained active is disconnected (it can react only when it is deactivated

again –the door is closed, etc.)

 If a CA-340 SIR wireless antenna is installed, then the activation of the engine

compartment switch is signaled with 5 quick chirps.

 If the alarm emits 6 quick chirps, it signals that the battery in one of the wireless

detectors is low. When the ignition key is switched on, it is possible to find out

which detector it is according to the fading of the LED (1 to 8 – pursuant to the

order in which the detectors are enrolled).

Temporary silent control and disabling of the

AUTOIMO

If it is necessary due to any reason (putting the vehicle in a car servicing

company for maintenance, holiday) the acoustic signaling and AUTOIMO

function can easily be temporarily disabled by switching off the ignition key

while holding the Valet button. It is confirmed with an acoustic signal. These

functions can be enabled again in the same way, on condition that they are

not disabled permanently in the settings.

Maintenance

The device does not require any special maintenance. We recommend regular

inspections of door and bonnet contact functioning, or possibly of the auxiliary

detectors. This inspection should be performed by a professional installer with

whom regular annual inspections should be arranged.
