This list of terms is arranged in alphabetical order.
Any term indicated by cursive (italic) letters within
the explanatory text can be looked up separately.
Abort Period:
When an alarm is initiated, the
internal sounder is activated first for a limited period
of time which is the abort period set by the installer. If
you cause an alarm accidentally, you can disarm the
system within the abort period before the real sirens
start and before the alarm is reported to the
remote
responders.
Alarm:
There are 2 kinds of alarm:
Loud alarm - both internal and external sirens blare
out constantly and the control panel reports the event
by telephone.
Silent alarm - the sirens remain silent, but the control
panel reports the event by telephone.
A state of alarm is caused by:
•
Motion detected by a
motion detector
•
Change of state detected by a
magnetic contact
detector
- a closed window or door is opened
•
Detection of smoke by a
smoke detector
•
Tampering
with any one of the detectors
•
Pressing the two emergency buttons simultaneously
(panic)
Arming:
Arming the alarm system is an action that
prepares it to sound an alarm if a zone is “violated”
by motion or by opening a door or window, as the
case may be. The control panel may be armed in
various modes (see
AWAY
,
HOME, INSTANT
and
LATCHKEY
).
AWAY:
This type of arming is used when the
protected site is vacated entirely. All zones,
interior
and
perimeter
alike, are protected.
Chime Zones:
Allow you to keep track of activity in
the protected area while the alarm system is in the
disarmed state. Whenever a chime zone is "opened",
the buzzer beeps twice. The buzzer doesn't beep,
however, upon closing the zone (return to normal).
Residences can use this feature to annunciate
visitors or look after children. Businesses can use it
to signal when customers enter the premises or
when personnel enter restricted areas.
Note:
Your installer will never designate a 24-hour
zone or a fire zone as a chime zone, because both
zone types actuate an alarm if disturbed while the
system is in the disarmed state.
Although one zone or more are designated as chime
zones, you can still enable or disable the chime
function.
Control Panel:
The control panel
is a cabinet that
incorporates the electronic circuitry and
microprocessor that control the alarm system. It
collects information from various sensors, processes
it and responds in various ways. It also includes the
user-interface - control keys, numerical keypad,
display, sounder and loudspeaker.
Disarming:
The opposite of arming - an action that
restores the control panel to the normal standby
state. In this state, only
fire and
24-hour zones
will
sound an alarm if violated, but a
“panic alarm
” may
also be initiated.
Disturbed Zone:
A zone in a state of alarm (this
may be caused by an open window or door or by
motion in the field of view of a motion detector). A
disturbed zone is considered “not secured”.
Forced Arming:
When any one of the system zones
is
disturbed
(open), the alarm system cannot be
armed. One way to solve this problem is to find and
eliminate the cause for zone disturbance (closing
doors and windows). Another way to deal with this is
to impose
forced arming
-
automatic de-activation of
zones that are still
disturbed
upon termination of the
exit delay. Bypassed zones will not be protected
throughout the arming period. Even if restored to
normal (closed), bypassed zones will remain
unprotected until the system is disarmed.
Permission to “force arm” is given or denied by the
installer while programming the system.
HOME:
This type of arming is used when people are
present within the protected site. A classic example
is night-time at home, when the family is about to
retire to bed. With HOME arming, perimeter zones
are protected but interior zones are not.
Consequently, motion within interior zones will be
ignored by the control panel, but disturbance of a
perimeter zone will cause an alarm.
Instant:
You can arm the system AWAY-INSTANT
or HOME-INSTANT, thereby canceling the entry
delay for all delay zones for the duration of one
arming period.
For example, you may arm the control panel in the
HOME-INSTANT mode and remain within the
protected area. Only perimeter protection is active,
and if you do not expect somebody to drop in while
the system is armed, alarm upon entry via the main
door is an advantage.
To disarm the system without causing an alarm, use
your control keypad (which is normally accessible
without disturbing a perimeter zone) or use a keyfob
transmitter.
