House Alarms FAQ

Summary of House Alarms

House alarms require minimal electricity to run. On average, a burglar alarm uses around 7-8 watts of power and consumes about 60-70 kWh of electricity per year. The power consumption may vary depending on the specific model and its features.

ADT alarm systems typically use a 12 to 24 volt transformer rated for 40VA, which is equivalent to 40 watts. The transformer can deliver this power continuously. Multiplying it by the number of hours in a month will give you an estimate of the maximum kWh used by the alarm panel.

Most home security systems use a battery that provides 12V and 4-8 amp-hours of power.

If there is a power outage, most alarm systems are equipped with backup batteries that automatically kick in to ensure continuous operation.

There are some disadvantages to consider when it comes to house alarms. They can be stolen or easily disconnected, especially wireless systems. Wired alarm systems require cutting into walls for installation and are susceptible to power outages.
