Normal Entry

Unsetting starts immediately when the FINAL door is opened or an ENTRY zone is activated. The sounder pulses slowly and the user must go directly to the keypad and enter a valid PIN, followed by A>, <B or ent. Users with group choice, will access the UNSET screen following PIN entry. This permits the user to unset specific groups. To return to the SET screen press ent.

Go directly to the keypad when entering the building. If the user strays into a protected area and activates a zone, an alarm will occur. The police may be called out and the system will have to be reset.

Slow Entry

Enter a valid PIN before the entry time expires. If the entry time expires before a valid PIN is entered, then an alarm will occur. The sounder begins to pulse quickly when 75% of the entry time has elapsed indicating time is running short.

Cancelling Alarms

To cancel an alarm, enter a valid PIN followed by ent at the keypad. The keypad displays details of the zone activated. When more than one zone is activated, details can be viewed using A > or < B. Press ent to return to the banner. Certain types of alarms, once cancelled, require a code with the appropriate reset authorisation to be entered. The system prompts for a valid reset code by displaying Manager Reset Re- quired or Engineer Reset Required on the keypad.

Manager Reset

Entering a manager type PIN followed by ent, resets the system following an alarm activation.

Engineer Reset

Certain types of alarm require an engineer to visit the site and, after investigation, reset the system. In such cases, the system cannot be reset until the engineer reset has been carried out.

Unsetting with the MAX Cards

If any of the groups assigned to the MAX are set, then swiping the MAX module with a card unsets the groups. Group choice and dual focus operation, where implemented will apply as per setting instruc- tions.
