A home alarm system can help to provide a sense of security and protect your home from theft and fire. A master code is used by the home security alarm installer and each one is usually unique to its installer. The master code is a four-digit code used to arm and disarm the system, as well as for programming additional access codes and changing other features. The master code is kept by the installation company in the event that it is needed in the future. You should also write down your master code in a safe place just in case you need to access it.

Press 8-1500 or 8-1550 on the keypad to enter programming mode. If the system does not beep, the panel needs a hard reset to clear all of the previously programmed codes.

Disconnect all power to do a hard reset of the system. This will reset all of the previously programmed codes, including the master code.

Leave all of the power disconnected for at least ten seconds.

Turn the power back on after 10 seconds. Once the system has been reset, all of the default values will be restored. The master code will also be reset to 1234.

Press 1234 and enter. This will allow you to enter the programming mode under the reset master installer code. Once you have done this, you may reprogram the codes as necessary.
