of once every two seconds. The display format of the LCD/VFD is shown in fig 1.4.1.

FIRE 01 Main Reception Area
ZONE 11 BREAK GLASS DEVICE 066 LOOP 01
When a fire alarm occurs, apart from all the other requirements of BS5839, the display
automatically identifies the device which triggered the alarm. The loop number, zone number,
device address and type of device are all displayed. After the word FIRE, the number 01 is
displayed to indicate that this is the first fire to be reported. Subsequent fires increment this
counter and also indicate in the top right hand section of the display the total number of alarms,
see fig 1.4.4. The display can be scrolled through the fires in the order in which they were
activated. The display format of the LCD/VFD for a single alarm is shown in fig 1.4.3.
