If the power goes out will my alarm system still work?

Yes. If the power goes out, your system reverts to a rechargeable backup battery. When the power turns back on the battery recharges itself. Depending on the system, all batteries must be changed every 3 to 5 years. Check with a Security & Cellular Plus specialist as we now offer an extended warranty program on battery replacements for the term of your alarm contract! Never have to worry about changing batteries again.
