by | Apr 22, 2022 | Blue Security Blog, Alarm Monitoring | 0 comments

We all know that when your home alarm sounds off in the early hours of the morning it is usually “go time” and you need to spring out of bed ready for anything! Similarly, everyone has, at one point, or another jumped out of bed only to confirm it was a false alarm and so appreciates the emotional roller-coaster and frustrations that we experience in these moments. Knowing what triggers your alarm unnecessarily is essential to ensuring it does not occur repeatedly. 

After all false alarms are a nuisance to you and come with costs and security implications for your service provider. 

To help you get started with combating false alarms here is a list of the 6 most common causes and steps you can take to resolve the issue from reoccurring. 

Power Failures and Loadshedding

There is a need for additional power supplies and bigger battery kits as we find loadshedding is pushing alarm systems’ battery backup capabilities beyond what they were originally designed to handle. It is important to note that a lead acid battery uses up to 50% of its rated capacity and the easiest way to overcome power supply issues for your home alarm system is to distribute the existing load evenly over multiple supplies as needed.

Old Equipment  

A general industry accepted lifespan of an alarm system is between five and seven years, depending on the environment. This, however, should never be taken as a strict rule. The pyroelectric sensor within a passive infrared detector, for example, starts degrading after about two years. This does not mean that the detector stops working, but that it may slowly become either more sensitive as it gets older, or less sensitive, and may be prone to false alarms, intermittent activations, or non-activations.  

Another example of a reduced lifespan is a system that is installed in an area that is prone to frequent lightning strikes in summer months. Constant exposure to static electricity caused by lightning can weaken the electronic components in a device, eventually leading to component failure.  

Building Renovations  

Your system was designed according to the original configuration of your home. False alarms may be caused by significant changes to that layout, even such interior changes as replacing window blinds with curtains, moving large furniture, and installation of fans or air conditioners.  

Pets and Wildlife

However, if you acquire a pet after installation, you may need to have your system modified so pets will not activate indoor motion detectors. Wildlife such as monkeys, rodents, birds, and feral cats may also affect the efficiency of your motion detectors.  

Moving Objects  

Ceiling fans, balloons, large plants, and objects that may fall are common causes of false alarms.  

Doors and Windows  

Be sure to close doors and windows securely, as they may trigger an alarm if blown open. Install appropriate locks to help protect them from wind, pets, or intruders in your home.  

Bugs, Pests or Dust on a Sensor Lens  

In Durban, geckos are a major source of false alarms when they crawl over motion sensors. New equipment includes mounting brackets that can reduce this problem. Alternatively, a mothball placed on top of the PIR will deter pests. Lenses should also be cleaned regularly.  

Malfunctioning Equipment  

Alarm activations for no apparent reason may be an indication of faulty equipment. If this is the case, it is important that an appropriately trained and qualified alarm technician is contracted to affect the repair 

Final Thoughts 

If you are among the many Durban residents experiencing problems and false signals with your alarm system, use the above points to attempt diagnosing the issues. If you would rather save time and money, contact our technical security specialists, and have a full site assessment of your current system.
