This list of terms is arranged in alphabetical order.
Abort Period: When an alarm is initiated, the internal built-in 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 built-in sounder and external siren blare out constantly and the control panel reports the
event by telephone or otherwise.
Silent alarm - the sirens remain silent, but the control panel reports the event by telephone or otherwise.
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 on the panel's keypad.
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.
Bypass: Bypassed zones are zones that are not armed when arming the system. Bypassing permits arming only part of
the system while allowing free movement of people within certain zones when the system is armed.
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. Businesses can use it to signal when
customers enter the premises or when personnel enter restricted areas.
Note: A 24-hour zone or a fire zone should not be designated 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 using the
chime ON/OFF button
and .LED
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 (e.g. 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 an “emergency 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”.
