  • Do I need a phone line to have an alarm?   No, but Cellular Monitoring is a higher monthly charge.


  • Can my VoIP phone line be used with my alarm?   In most cases transmissions do go through.  However, it is not supported by our panel manufacturer.  Therefore we recommend using a POTS line or our most reliable method-Cellular Monitoring.


  • What is “Cellular Monitoring”?   Basically, without a phone line for the alarm to communicate, National Alarm provides an extra piece of equipment that will allow transmissions to our central station via a cellular radio.  Think of it as a cell phone just for your alarm.


  •  What is a Central Station?   Central-stations use special phone lines, computers, software and trained staff to monitor their customers’ security and/or fire systems and call the appropriate authorities in the event an alarm signal is received.


  • Will my alarm work if the power is out?   Yes it will.  Our alarm systems are equipped with a battery back-up that will power your system for no more than 48 hours.  In most cases AC power is only out for a few hours.  Upon restoration of main power the battery will recharge.  Your battery will last an average of three years as long as it is not compromised.
