to the fire as follows:
 Common FIRE LED will turn on steady
 Assigned zone fire LED will illuminate
 Panel buzzer will sound continuously
 Fire condition to be reported to the LCD (time ordered buffer 100 entries deep)

The fire condition will be displayed on the LCD in the following format:
Zone with active Fire condition

ZONE FIRE XXX OF XXX DEVICE►
The LCD will display the zone in which the fire originated and can be scrolled through all zones in

The user can perform the following actions in response to a fire:
 The SILENCE/RESOUND key is used to silence any silence-able outputs that have been
activated in response to the fire condition. The ALARMS LED will be illuminate to indicate
that the sounders have been silenced and resound is available. The operation of the
SILENCE key will be logged. (This operation is only available at access level 2)

Device Alarm LED activation
Due to the limited current available from the analogue loop, the number of alarm LED’s allowed to be
illuminated simultaneously is limited to the first 10 devices in fire on each loop; after this limit is
reached any new devices in fire will not have its alarm LED illuminated until the original fires have
been cleared on that loop.
