Can you explain the difference between an access code, a passcode and a personal identification code or number?

An access code is the sequence of numbers that you enter into a keypad to control your alarm system – such as arming, disarming or bypassing.  A passcode and a personal identification code are very much the same thing – a confidential sequence of numbers and/or alpha characters used to verify who you claim to be when your call our Signal Receiving Center.  Both access codes and personal identification codes should NOT be shared with anyone.
