Whether there is an DSC alarm system installed in your home or office, you will eventually confront false alarms or a faulty keypad. These will sound quite unbelievable in every sense, yet they can be very annoying and perhaps a bit frightening at times as well. Fortunately, we are here to assist you in understanding how to bring about repairs in some of the common problems that are experienced with DSC alarm systems.
1. False Alarms
The most common problem associated with DSC alarm systems is false alarms. The reasons for such alarming situations can be anything, like poor functioning of sensors, low battery, and so on. The solution to such a problem is to check all the batteries of your sensor and replace the batteries whenever required. Another solution would be changing the sensitivity settings of the alarm system to decrease chances of it going off falsely.
2. Keypad Malfunctions
When you're having trouble navigating the DSC alarm keypad, it becomes almost impossible to arm or disarm your system. The condition can be caused because of different things such as dirty keypad or loose connections. So, have your quick start-up on cleaning the keypad using a soft cloth with a little rubbing alcohol. If that's effective, the connection or the keypad may need to be repaired if the error still returns.
3. Communication Errors
If your DSC alarm system is having problems communicating with your monitoring service, you may be in a vulnerable state. This problem can be caused by, for example, a broken telephone line, a weak cellular signal, or a misfortune in the programming. To fix this problem, first, check a telephone line or a cellular signal. If everything looks good and working, you might have to reprogram your current alarm system or you can call for the monitoring service help.
4. Zone Sensor Failures
When you have one of your zone sensors not working properly, it might endanger the safety of your property by making it vulnerable to intruders or other threats. This concerns the failure of the sensor that might be produced by a range of things, such as lack of a charged battery, a sensor that is not correctly installed, and probable physical harm. To deal with this dilemma, you'll first have to check if the battery is low enough to be changed on the sensor and change it if needed. You can proceed further by the realignment of the sensors or winding up the damaged and substitutable sensors.
5. Sensor Calibration
Are you having problems with your DSC alarm sensors not detecting movement or the opening and closing of doors and windows? Most of the time, it is a result of calibration problems, which can really affect the whole alarm system and put your house at risk. You need to adjust the sensitivity settings of your sensors according to the manufacturer's instructions to solve these problems. Try subjecting your sensors to regular testing to ensure they are working correctly in detecting activity. If these sensor calibration problems persist, replacing the sensors for a new set would be an option to restore function to your alarm system.
In brief, the difficulties encountered by the DSC alarm are really headaches, but patient troubleshooting and a little bit of knowledge will help you sort the problems really fast and with ease. If you stick to the instructions given previously, you will surely have the satisfaction of the DSC alarm system working ideally as well as offering its function of security and peace.
