Hi all. I know, it's a very old alarm. I am about to complete the sale of my house and want to change access code. The user codes are all unset, and when I set the system I can do it by just hitting the A key i.e. I don't need to enter the access code. I have the Engineer manual etc, but there's no mention of just hitting the A key. I'm assuming that the code we are using is actually the manager code. I see in the engineer manual that I can reset that to default, but am nervous of setting off the alarm. Can anyone help me with changing the access code? Are we using the manager code and can i set it to default?
Thanks in advance.
Thanks in advance.
