Anti-Theft - Perimeter The anti-theft perimeter protection feature is controlled by the front electronic module (FEM), the rear electronic module (REM), and the driver door module (DDM). The alarm can be armed using:

• the LOCK button in the remote keyless entry (RKE) transmitter to the DDM, which sends a message through the standard corporate protocol (SCP) communications network to the FEM.
• the driver or passenger door lock switch if the corresponding door is open when LOCK is actuated.
• the key in the driver door lock cylinder.
• the RKE keypad by pressing 7/8 and 9/0 simultaneously.

The FEM and REM then monitor all features, which activate the alarm in the event of an unauthorized entry.
The luggage compartment lid lock cylinder does not disarm the vehicle's perimeter alarm. The luggage compartment alarm can be temporarily inhibited through the luggage compartment lid disarm switch, located in the luggage compartment lock cylinder or by opening the lugguage compartment with the RKE transmitter or the RKE keypad. Once the luggage compartment lid closes, the perimeter alarm system immediately starts monitoring the luggage compartment. The perimeter alarm can only be disarmed:

• by unlocking the vehicle using the RKE transmitter.
• by unlocking the vehicle using the driver door lock cylinder switch.
• by cycling to RUN a valid programmed key in the ignition switch.
• by entering the correct vehicle unlock code on the RKE keypad.

Additionally, an ignition switch tamper circuit and a signal hardwire line from the FEM to the REM are monitored.
If any of the above features receive any activation once the alarm is armed, the alarm activates the visual and audible alerts. ......

If you do not get a better answer than this on this web-site, recommend you call a Mazda dealer and ask them the answer.
God bless your efforts.

well all doors has to be closed before you hear chirp noise,if you leave one door open the alarm activate noise wont sound all doors has to be closed.

its the door switches they are sticking and telling the car door is open. open and close both doors a few times and make sure they are closed good and try again to make sure it is setting properly you will know cause the care dome light will go and it will emit a short honk when activated!! =) mine just did the same thing

Try this first before buying a new battery or replacing with a new aftermarker alarm. (1) Make sure all doors are closed completely and locked (2) On the drivers door, use your key to turn LOCK then UNLOCK, Open the door and close then repeat again (3) Proceed to Sliding door and turn UNLOCK - you should hear all doors unlock and you've completed the factory reset. Open driver door and turn ignition, your vehicle should now start.

go to profile activate silent mode in the settings alarm mode vibrating

Is your perhaps alarm in "valet mode"? I've got a Checkmate on my Honda, and I can turn valet mode on/off by putting the key to Accessory, then pushing the black button under the left of the steering wheel. The alarm chirps when you switch the mode.

Well as I see from the owner manual for this device the sub is active one and my opinion is that electric is your problem.The power of the sub and main unit must be on the same phase otherwise you'll hear brrrrr or frequency of your main unit power supply on the sub.Thats why sound changes when you open or close the door.Take one power distribution cord (get power for bought devices from the same place) and connect main unit and the sub on it and then try.I hope that this will help you

that because the internal fan is hiting the ice or has bad bushings you can hear the noise just with the door close because when you open the door there is a switch the one turns off the internal fan so when you close the door it turn on the fan again if you wants to hear that with the door open just open the door and push the botton swich with your fingers and you'll hear the noise
