4.4 ZONE INDICATORS
NOTE: In the following sections the following abbreviations are used to describe the
LED indications:
OFF = LED unlit.
SF = LED flashing slowly (every 2 seconds).
F = LED flashing (every half a second).
RF = LED flashing rapidly (10 times per second).
ON = LED on steady.
4.4.1 ZONE ALARM ("ALM") LED INDICATOR
A RED indicator per zone that is interpreted as:
(a) OFF For Alarm Zone; The normal, non-alarm state
For Ancillary Zone; The normal, non operated state.
(b) ON For Alarm Zone; Indicates the alarm condition has been acknowledged and if
the zone is non-latching that the alarm condition still exists.
For Ancillary Zone; Indicates that the Ancillary Control Zone has been
activated.
(c) F For Alarm Zone; Indicates a new, yet to be acknowledged, alarm has
developed or failure of self test e.g. unexpected alarm in the zone.
4.4.2 ZONE FAULT ("FLT") LED INDICATOR
An Amber indicator per zone that is interpreted as:
(a) OFF The normal state.
(b) ON Indicates a FAULT condition has developed in that zone.
For Alarm Zone; A detector line fault
For Ancillary Zone; An Ancillary Supervision fault.
(c) F Encountered during a SYSTEM TEST, to indicate that the particular zone
failed its test sequence, or detected an unexpected alarm or fault.
NOTE: For New Zealand mode FIPs, zone defects (faults) are always non-latching,
but the LED indicators are always latching. Thus, if the defect condition goes
away, the zone status will be normal, but the defect indicator will remain ON
until the zone is RESET.
