This option provides a record of the most recent alarm activation. The Trace option records the details of the setting and unsetting of the sys- tem immediately before and after the alarm activation and the first 5 events occurring during the alarm activation. This information is main- tained in the trace until the next alarm activation. On entering the op- tion pressing the A and B keys steps through each of the 7 trace entries.

Pressing the # key while viewing the Trace option displays additional information about certain events — user events reveal the keypad, user level and current group; alarm events reveal the zone descriptor if pro- grammed.

The currentt display trace can be printed out by pressing the key; pressing the esc key aborts the print-out.

This function allows the programmed times in each of the timers to be viewed and switched on and off as required. Use the A and B keys to scroll through each of the programmed times.

NOTE: The programmed times cannot be modified using this option.

2=Holidays

This function allows up to 10 holiday periods to be allocated. A Start and End date is entered for each holiday period using the 1=Modify Dates option. On selecting this option, the Start and End dates for holiday period 01are displayed. If no dates have been entered for this period, then the display will show **/**. To program the Start date, press the ent key; the date display changes to >DD/MM< ; enter a valid 4 digit number and press the ent key to accept the selection. The year is not required, only the day and month.

Press the # key to move to the End date and follow the procedure for programming the Start date.

To remove a programmed date, press the * key. The date display re- turns to **/**.
