  • We are going out of town, who do we call?
    Notify the Post Alarm monitoring department with your name, address and codeword. Be sure to provide the operator with detailed information such as whether someone will be at the property, any temporary contact information for yourself or for those staying in your home, and dates for your departure and return.
  • I was notified of a scheduled power outage, what should we do?
    Notify the Post Alarm monitoring department with your name, address, codeword, dates, and times.
  • We have construction workers at the location, whom should we notify?
    Notify the Post Alarm monitoring department of daily activity with estimated work hours. Also indicate if you are authorizing the operator to place the system on test and if alarms during that time frame should be ignored. (Codeword must be available.)
  • Our company just terminated an employee, what should I do?
    Does the terminated employee know the codeword or have alarm code? If so, submit in writing the codeword change with authorizing signature. Also change the alarm code immediately.
  • I have a temporary house guest. Can this person have a temporary codeword?
    Yes. Please submit a request with your name, address and current codeword. Also give us the name of your house guest, the dates they will be staying at your house and the temporary codeword for your guest to use.
  • I received my permit number and/or renewal, should I notify Post Alarm Systems?
    Yes, call Post Alarm monitoring department with client name, address and codeword.
  • Why is my system beeping and how do I make it stop?
    During a power outage, some systems begin to beep when the AC 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, there may be 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, the backup battery begins to supply power to your 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 AC power.
  • Will my system still work when the power goes out?
    Yes, your alarm system will work for the life of the backup battery. Although the system will still work, it is a good idea to have a radio backup 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 at 626-446-7159 for more details on adding radio back-up to your system.
  • What are my options for paying my bill?
    You can go to our website and make a payment, or can you can call into our accounting department to make a one-time payment and/or to get your account set up on auto debit. We take Visa and MasterCard, or we can have it taken directly from your checking or savings account.
  • When is my bill due?
    We mail the bills one month in advance and they are due by the 1st of the following month.
