APPENDIX C: Glossary
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 alarms:
Loud alarm - both internal sounder and external siren 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
).
Assigned:
Refers to zones.
Associated:
Refers to devices.
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 does not 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.
Communicators:
Refers to communication channel, for example, GSM.
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.
Default Settings:
Settings that are applicable to a specific device group.
Detector:
The device (apparatus) that sends an alarm, that communicates with the control panel (for example,
Next PG2 is a motion detector; SMD-426 PG2 is a smoke detector).
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.
