What is a false alarm?
The City of Carrollton's Alarm Ordinance defines a false alarm as:
“An alarm notification to the Fire or Police Departments, when the responding personnel find no evidence of fire/EMS or unauthorized intrusion, attempted unauthorized intrusion, robbery, attempted robbery or an attempt to take a person hostage; and, the responding personnel arrived within 30 minutes of the notification.”
Why are false alarms a problem?
False alarms place an unnecessary burden on first responders, taking them away from real emergencies and can delay critical help. They also strain resources, increase costs, and impact public safety.
In Carrollton, repeated false alarms can result in fines, with charges increasing after multiple incidents.
By preventing false alarms, residents and businesses help avoid unnecessary fees, ensure emergency crews are available when they’re truly needed, and improve community safety.
What are causes false alarms?
Nearly 80% of false alarms are caused by user error. Other common causes include issues with alarm installation, maintenance, or equipment failure. Understanding these causes can help alarm owners reduce unnecessary activations.
Examples of False Alarm Triggers:
- User Mistakes: Entering the wrong code, forgetting to disarm the system, or not training others who use the alarm (like children, employees, or cleaners).
- Unlocked or Loose Doors and Windows: These can move and trigger sensors when the alarm is armed.
- Pets and Wildlife: Animals can trip motion detectors or activate glass break sensors.
- Objects or Conditions in the Environment: Drafts that move curtains or plants, helium balloons, or even items falling can cause false alarms.
- Improper Installation or Equipment Failure: Faulty wiring, low batteries, or outdated equipment can lead to unnecessary activations.
By addressing these common triggers, residents and businesses can prevent false alarms, avoid fines, and ensure emergency teams are ready to respond to real emergencies.
What do I do if I accidentally set off my alarm?
- First, don't panic. Carefully enter your disarm code to reset your system.
- Wait for your Alarm Company or central monitoring station to call, then provide them with your password or ID card number.
- Do not leave your home or business until you have talked with your monitoring station. Always have the monitoring station's number posted by your control panel. If the monitoring station does not call you, contact them to cancel the police dispatch.
- DO NOT call 911 to cancel alarm activations--you must call your monitoring station.
- You can arrange to have your alarm monitoring station call you or another designated person first before the police are called whenever your alarm is activated.
- If you are aware of a problem with the system, you can cancel the police dispatch.
Here are some easy tips you and your alarm company
can use to prevent false alarms:
- Before You Activate Your Alarm System:
- Are you and others who use the security system fully educated on its proper operation? This may include domestic/cleaning crews, children, neighbors, caretakers, employees and temporary staff.
- Make sure you securely close and lock all protected doors and windows.
- If you are leaving your home or business, make sure the door you leave by is closed tight.
- Keep pets, balloons, fans, heaters, etc. away from motion sensor areas.
- Know and rehearse the process to cancel an accidental alarm. Anyone with your key should know this process.
- Know how much time you have after you activate your system to leave and to disarm your system when you enter.
- At Home
Avoid objects that trigger your alarm:
- Unlocked, loose fitting, or open doors or windows. Always keep doors and windows locked when the alarm is in an "ON" mode to reduce the chance that friends, neighbors or customers enter and cause the alarm to activate.
- Unsupervised pets - If you have pets, take special care to purchase an alarm system that is
tolerant of pets. You may not want to purchase motion detectors if your pets have free run of the house when the alarm is on. Also, sometimes barking dogs can activate glass break detectors.
- Balloons that move and cause motion sensors to go off.
- DO NOT call 911 to cancel alarm activations; you must call your monitoring station.
- Drafts that move plants and curtains.
- At your Business
Watch for these pitfalls that may activate your alarm:
- Swinging doors or windows
- Banners or signs
- Mylar balloons
- Plants or curtains caught in drafts
- Stacked items, such as boxes, which may fall, setting off motion detectors
- Unsupervised guests
- Untrained employees
- Alarm equipment, such as motion sensors or overhead door magnets, being hit by forklifts
- Contact your alarm company:
- If you plan any home improvements or renovation projects, such as changing phone systems, the configuration of a room, adding a wall, rearranging cubicles, installing skylights or ceiling fans, or even fumigating.
- If you plan to change your alarm system batteries, which can cause an interruption to your system’s power supply.
- Also alert your alarm company if you acquire a pet or hire domestic help.
- Review with your alarm company what procedures they will follow if/when your alarm activates:
- Will they attempt to call more than one person on your contact list before requesting emergency dispatch?
- What criteria do they follow to determine when to notify the police?
- Request their procedures in writing.
- With people:
Enhance your alarm system’s potential:
- Train responders who have premise keys on complete system operation.
- Instruct domestic or repair persons that you have an alarm system and what to do in case they set off the alarm.
- Lock your doors using dead bolt locks.
- Recommendations:
- Have a maintenance contract with a licensed alarm company and have your alarm system checked every year.
- If you are apprehensive about using your system, call your alarm company.
