Alarm Verification Facility. A means by which the c.i.e. re-samples
the smoke detector to confirm smoke is still present.
An operator action to record the indicated zone alarm has been seen,
for example, when handling AIF alarms.
This is the state of a point which is not in its "normal" or idle condition,
nor in fault. Examples are: a detector in alarm, a relay or LED turned
on, an input switch being closed.
The devices used to warn the occupants within the protected
premises of an alarm. These include sounders, hooters, sirens,
occupant warning systems with speech, and may also include visual
indicating devices such as beacons or strobe lights.
The Alarm List is the list of current alarm conditions. When the Alarm
List is shown (as in the Quick Reference at the front of this manual)
the fire brigade panel controls function in accordance with the
requirements of NZS 4512.
The transmission of an alarm condition to a remote monitoring centre
to summon the fire brigade.
The same transmission medium is often used to also transmit a fault
condition (Fault Routing) to the monitoring centre to summon a
service agent.
An in-situ detector test mode (sometimes called “Walk Test”), which
allows detectors to be alarm tested in their installed positions. The
zone is disabled and detector algorithms are bypassed to allow the
detector to go into alarm quickly. The detector is automatically reset
to allow the next detector in the zone to be tested.
This is the display shown without operator intervention, or when the
CANCEL key has been held or pressed a number of times to get
back to the top display. The MX1 may be showing normal, faults,
disables. The Alarm List is a special base display (but is not classified
as the Base Display in this manual).
Carbon Monoxide – a colourless poisonous gas that moves by
diffusion, emitted by smouldering fires.
Smoke detectors can become contaminated due to a buildup of dust,
dirt and other foreign particulates inside the sensing chamber. MX1
monitors the detector reading as it increases due to dirt buildup, and
compensates by shifting the alarm threshold to maintain a consistent
sensitivity to smoke. It signals a dirty state for the detector when this
reading indicates that the level of contamination is such that it can no
longer be compensated for.
From this point onward (until the detector is cleaned and replaced) it
is more sensitive to smoke and thus more likely to produce a
nuisance alarm.
Flat ribbon cables, usually internal to the c.i.e. cabinet.
An alarm condition that occurs without the presence of a fire.
The point is in a condition other than normal, for example fault,
disabled, active, etc.
A system condition where there is one or more points or zones that
are not normal. That is, a point or zone has a status other than
normal – for example, Fault, Alarm, Dirty, or Device Fail.
A configuration where a smoke detector alarm does not activate the
alarm devices and alarm routing. Only a warning local to the
originating detector is given.
