  • I received my permit number and/or renewal, should I notify Post Alarm Systems?

  • Why is my system beeping and how do I make it stop?
    During a power outage, some systems begin to beep when the a.c. power is turned off or turned back on. If your system is beeping, it needs to be “Acknowledged” through the keypad. This may need to happen both when the power goes off and comes back on. Acknowledging the system is easy and can be done by you. The instructions for Acknowledging the System are in your user manual under Trouble Conditions. It will save you time if you are able to Acknowledge the System yourself as opposed to having our technical support walk you through the process over the phone. Our technical support receives many phone calls during power outages and although we try to help everyone quickly, you still may have a wait time. If you are not able to Acknowledge Your System we would be happy to walk you through the process over the phone. In-house technical support is available Monday through Friday 8 a.m. to 5 p.m. at 626-446-7159. If you need immediate assistance on the weekends or after normal business hours, we have on-call technicians who can assist you (please note that there is an additional fee for after hours service).
  • What happens to my system when there is a power outage?
    When the power goes out, your back up battery begins to supply the power to the system. Your system will also notify you at the keypad that there is a Trouble Condition. A Trouble Condition is just a warning. Our Central Station will receive the Trouble Condition signal and notify you of the loss of a.c. power.
  • Will my system still work when the power goes out?
    Yes, your alarm system will work for the life of the back up battery. Although the system will still work, it is a good idea to have a radio back-up device in case the phone line becomes damaged due to bad weather. Radio back-up is available through our company and can be added to most systems. It is standard on all new systems but may need to be added if your system is more than a couple of years old. Please call the Service Department 626-446-7159 for more details on adding radio back-up to your system.
