On the alarm, what does the yellow triangle mean?
A yellow triangle light on the DSC alarm indicates that there is a problem that has to be resolved. A trouble light can indicate a variety of issues that are generally denoted by an error code.
The zone lights will turn on and a fault code relating to the specific issue will appear on the display screen if you press [*] on the keypad. To figure out what the difficulty code indicates and how to resolve it, consult the table above. The triangle light goes off after you clear the fault code.
DSC alarm is not arming
The DSC alarm system is secured once it is armed. If your system is not arming, it usually means there is a power outage. During a power loss, the DSC alarm system contains a backup battery to keep it armed. Your security and smoke detection will be jeopardized if the equipment are not armed. To get your alarm system properly armed, follow the troubleshooting methods below.
Dead or low battery
If the system refuses to operate, the battery may be low or entirely dead. Check the batteries in the control panel, keypad, and sensors, and replace them if required, to guarantee that your alarm system enters into arming mode appropriately.
Tripped circuit breaker
Check for tripped breakers if your home has electricity but the alarm system is not activated. Power surges and outages can sometimes trip the circuit breaker, preventing the system from getting power. The batteries do not recharge while the system is not receiving electricity. Check the circuit breaker and manually turn it off and on to see whether it’s tripped.
A step-down transformer is also included in the DSC alarm systems, which connect into an alternating current outlet. The transformer is most likely failing if there is AC power and the batteries are also operating but the system isn’t arming. First, double-check that the transformer is properly inserted into the power socket. Then, by removing and reinserting the other end with a single plug, double-check that it is securely put into the central alarm unit. Replace the transformer if the problem persists.
DSC alarm is not beeping when the door opens
DSC alarm system should beep every time you open or close a door or window with a sensor. However, on rare occasions, the door will not chime when you open the door. Follow the troubleshooting steps below to get your Chime function working again.
Toggle the Chime feature
Check to ensure the chime function is enabled. Turn it on by pressing and holding the Chime button on the keypad for 2 seconds. You can also press [*]. Finally, test the door and if it should beep three times if the chime is on. If it is off, the system will produce a long tone.
Check the sensors
Confirm the door sensor is activated. To test this, turn off your alarm system and check if the sensor was recently triggered. Ensure the sensor is programmed to switch off the main power supply automatically after some time. If it has, you should disconnect the sensor battery, reattach it, and set the current time and date.
Confirm power failure
Check for power to the system. During a power outage, the system usually works on the backup battery. But if the battery is completely dead, the alarm system won’t work. Check the circuit breaker and reset any tripped switches. Then check the batteries on the sensors and keypad and replace them if necessary.
Test the door contacts
Check the door to ensure the contacts are not loose or damaged. When the sensor contact is damaged or disconnected, the alarm system will not notify you in case of an intruder. If they are, set the system to bypass the zone where the door is and then reconnect the contacts or replace them. When replacing the contacts, make sure to use a replacement door sensor and magnet compatible with your current system, or the control panel will not recognize it.
DSC alarm is not communicating
When the DSC alarm system is triggered, it links directly to the phone line, allowing it to communicate with the monitoring department about a break-in, fire, or other safety threats.
Phone line repair work can usually create a communication failure by disrupting the link with the alarm system. A severed phone line, a change in phone service, a phone malfunction, or a change in phone service provider are the most likely causes. Here’s how to fix the communication problem:
- Check that the phone line to the system’s control panel is securely connected. After that, double-check both ends by firmly removing and rejoining the connection. Then, test it to make sure it’s operating properly.
- The system is not configured to transmit test signals if the monitoring station does not receive the test message. For an onsite service call, you must contact DSC support.
- A frozen cellular unit might potentially be the cause of communication failure. This may be fixed by restarting your DSC alarm system. Then, to determine if the problem has been resolved, do a communications test. You’ll need to make a service call if the communications test fails.
DSC alarm battery is not charging
The alarm system battery delivers backup power to run the system during power loss. The DSC alarm system uses 12-Volt batteries that typically last between 3-5 years. When the battery has fully discharged, a trouble light code ‘7’ or ‘low batt’ will appear on display. Try replacing the battery, and if the problem persists and you have an older system, you should consider replacing the system.
How do I know if my DSC keypad is not working?
A dead keypad will not beep or have lights on it, indicating a problem with the power supply to the keypad. Try the troubleshooting steps below to get your alarm keypad working:
- Reset your alarm system to factory default to clear out minor bugs that could be affecting your system. After the reset, reprogram the system.
- Confirm the keypad is receiving power by removing the battery from the back of the battery cover. Wear ear defenders in case the alarm is triggered. The keypad will produce two beeps.
- Make sure the batteries are correctly in position by checking the polarity.
- Check the transformer plugged into a working AC outlet. Test the outlet by unplugging it and connecting another electrical device. If the device doesn’t power up, check the circuit breaker and reset any tripped breakers.
- If the keypad problem continues, you should call a DSC technician to fix the issue.
DSC alarm panel is not responding/working
The principal controller of the alarm security system is the alarm control panel. It’s a computer that armed and disarms security systems, connects with all components, sounds the alarm, and alerts the security monitoring station when there’s a security breach. A malfunctioning control panel may display zone problems, making it impossible to set the alarm. Below are the most common alarm panel malfunctions and fixes.
The backup battery must be recharged using AC power. If there is a protracted power outage, the security system will be disabled until the power is restored. Replace the dead battery with a charged battery to get your panel operating again. The battery will most likely cease recharging after four years and will need to be replaced.
When the sensors detect movement, they alert the panel, which sounds an alarm and sends a message to the monitoring station. The pins in the sensors might sometimes clog or loosen, preventing the alarm from being activated. The remedy is to locate the malfunctioning sensor and correctly install or replace it before testing it. To avoid this problem, you should maintain the sensors on a regular basis.
Loose wire connections
Loose connections can cause the alarm system to fail in several ways. The wires or cables connect the components to the main power supply, and if they are loose or damaged, the panel will not work correctly. Inspect all the connections in the system and ensure they are firm and secure. Wires can also become frayed or corroded and will require replacement. Check all the screws are tightly fitted and replace any missing screws.
Here is how to DSC Alarm Trouble Light Reset.
Pull down the panel that covers the keypad on your alarm system. After this, simply enter your 4-digit master code, wait 2 seconds, and then enter it again.
Hold down the reset button for 2 seconds. This button is often situated on the keypad’s bottom right side. To disable the alarm, hold it down for at least 2 seconds. The lights on the alarm will change from red to green to indicate that the alarm has been reset.
Press “*72” if the alarm is still ringing. Enter the code “*72” into the keypad. This resets the smoke sensors, causing the alarm to cease sounding if it is still ringing. Once you’ve input the code, hit the “Enter” button on your keypad.
How to find the Master code for my DSC alarm
