Allow Swinger Shunts: If programmed, a zone can
only alarm or trouble up to three times per armed
period. After the third alarm or trouble, the zone will be
bypassed and a bypass report will be sent.
7.2.2 Zone Function Programming
Zone Function: A Zone Function is the description of
how a particular zone behaves(for example, steady
alarm output, bypassing allowed, alarm on short,
trouble on open, perimeter instant).
• There are many possible zone functions. Up to 30
different zone functions are allowed per control
panel.
• Zone functions may be custom made as needed.
• Each zone must be programmed as a specific zone
function. Any number and combination of zones
may be programmed as particular zone functions.
• Program zone functions at addresses 0001-0030.
Invisible Alarms: This is a zone programmed not to
have an alarm output or an alarm display at any keypad
when activated. An alarm signal will be sent, but the
DS7447E/DS7447V2 keypad display will read “Not
Ready” while this zone is violated.
• Invisible Alarm zones are recommended for holdup
alarms.
Silent Alarms: This is a zone programmed to activate
the visual display at the keypad, but not audible signals.
• If this zone is also an entry zone, an entry tone will
sound when this zone is activated.
Bypassing Allowed: This is a zone programmed to
allow bypassing (shunting). This is done using the
bypass command or the force-arming sequence.
Alarm on Short: This is a zone programmed to
activate an alarm when its loop is shorted.
Alarm on Open: This is a zone programmed to
activate an alarm when its loop is opened.
Trouble on Open: This is a zone programmed to
activate a trouble when its loop is opened and the
system is disarmed.
• If the system is armed, this zone will activate an
alarm if shorted or opened.
• For 24-hour zones, regardless of the arming state of
the control panel, this always remains as a Trouble
on Open.
Trouble on Short: This is a zone programmed to
activate a trouble when its loop is shorted and the
system is disarmed.
• If the system is armed, this zone will activate an
alarm if shorted or opened.
• For 24-hour zones, regardless of the arming state
of the control panel, this always remains as a
Trouble on Short.
Interior Delayed: This is a zone programmed to be
ignored during the entry/exit delay period. If it is
violated when the system is armed, it will activate a
delay for the programmed entry delay time. The
keypad pre-alert sounders will activate and the system
may be disarmed during this delay period. If the
system is not disarmed during this delay period, this
zone will activate an alarm. This zone is bypassed by
Perimeter Instant or Perimeter Armed.
Perimeter Instant: This is a zone programmed to
activate an alarm even during the entry/exit delay
period.
24-Hour: This is a zone programmed to activate when
its loop is faulted, even if the system is disarmed.
Entry/Exit Delay #1: This is a zone programmed to
be ignored during the entry/exit delay period.
• If it is violated while the system is armed, it will
activate a delay for the amount of time
programmed for entry delay time #1 (address
4028). The keypad pre-alert sounders will activate
and the system may be disarmed during this delay
period.
• If the system is not disarmed during the entry
period, this zone will activate an alarm.
Entry/Exit Delay #2: This is a zone programmed to
behave identical to the Entry/Exit Delay #1 zone
function except that it uses entry delay time #2
(address 4029).
If both entry delays have been activated,
the control panel will use the shorter entry
delay.
