Check any alarms that may be set. Lok at the system clock, and any timing applications. Check your anitvirus for schedualed times for scaning.
Good luck

Why would the alarm stop making sound.


Is their an on board fuse on the control panel. Also what you could do to troubleshoot is disconnect the siren red wire ad touch it to a 12vdc terminal on the panel. Make sure you are not touching it to a 120ac terminal. Are you talking the keypad makes no noice or the siren does not work?

I need to switch off my car alarm


Hi
You car is now of an age where by the ni.cads in the alarm have failed an are causing a current drawn when the car is turned off..the alarm sees this current draw as a theft so the alarm sounds.
Either replace alarm siren assy (fitted with new ni.cads) or remove the siren (or just unplug it).

Beret 2 way 5000m alarm siren problem.


These Alarms are so very fickle. If the Alarm lasted a year, then you are out of warranty and I have removed more than my fair share of Alarm's. As the Vehicle owner, you need to realize that your problem is quite common and you should be grateful it has not complete immobilized your bike. My Recommendation is... Remove it and return it to Stock or spend the money and get a higher quality alarm with a great reputation. Don't truck the Install Shop, they get tied to one brand, find the Alarm that meets YOUR NEEDS...

The systems is working fine and no indications or warnings on the panels, but you can hear the siren at a low sound at all times. All the zones are working according to the panel and alarm monitoring...


The siren should not receive any power when in idle mode (non alarmed state). If you hear any noise, it receives some kind of low voltage. Is it powered straight from the panel or with external power supply and aux. relay? In any way - use a volt meter and measure across the sirens power terminals. If you have any voltage present check the source.

My alarm is testing multiple times a day


Check that the battery is installed the right way around. Most smoke alarms can only be tested manually (by pushing the button). If you are hearing a single beep every 50 or 60 seconds then this is the low battery indicator and this will sound if the battery is inserted the wrong way around. If the siren is actually sounding continually then your smoke alarm might be clogged with dust or other foreign matter. All smoke alarms should be replaced every 5 to 7 years as the components in them only have a limited life span.

The alarm doesn't sound when the alarm is tripped


This can be caused by either a blown siren power fuse on the motherboard or a blown voice coil in your siren. It would be best to have someone with an electronic background check this with a volt/ohm meter. If voltage is present at the siren during an alarm but there isn't any sound then you will need to replace the siren. On the other hand if no voltage is measured then you need to find and replace the fuse that sends voltage out from the motherboard to the siren.

2002 Saab 9.5 Griffin 3L Turbo. Alarm comes on, for no reason?


Your alarm siren is the problem. You can replace the siren or have the Saab dealer program your car NOT to use it and remove it. When you turn off the ignition your SID will not display anything, unless the key in the ON or START position.

Volvo s80 alarm


Have the codes read out for the vehicle. It is likely that the siren for the alarm is causing the false alarm. If the siren is bad, there will be a code set in the central electrical module. (CEM)
