Access Authorization (User Type 3.6)

Menu Option 48 allows access to be authorized for engineers for system programming and for managers in order to add/delete/change all user codes.

1 = Engineer

The engineer code is assigned programmed as dual by default. This prevents the engineer from accessing engineer mode unless authorized to do so by a valid code. To gain access to the engineer menu a type 3.6 user must enter their code, and enable the EngineerAccess option. This provides a five minute period during which a single entry of the engineer code provides access to engineering mode without causing a tamper alarm. Once the engineer mode has been accessed, there is no time limit on the access period.

If the Engineer Mode option has not been enabled, or the code is not entered within the five minute period, then the Engineer code is invalid and has no effect.

If the PIN is programmed without the #, the Engineer Access option does not require to be enabled to allow the engineer to gain access to engineer mode. The engineer code requires to be entered twice. The first entry activates a tamper alarm which is cancelled by the second entry.

NOTE: Dual entry of the engineer code in a system requiring user authorization does not give access to engineer mode.

2 = Manager

This option allows type 3.6 manager codes to be enabled for user code adding/deleting/changing. This option can only be enabled by the au- thorization code. However, this option is not used by default. Manager codes are always authorized. It can be enabled, if required, to comply with standards in certain regions. An authorization code must be as- signed in Menu 42 Codes, before the function is enabled.
