tem will arm normally. If the test fails, the system will arm, but
will indicate a trouble condition.
- The DS7447 keypad will display “Communication Err” after [#]
[8] [7] is entered.
- This can also be used to perform a bell test on arming.
• Siren on Comm. Fail for Silent Zone: If programmed, a silent
zone will sound the alarm outputs if the zone is in an alarm condi-
tion and the system fails to communicate with the central station.
• Restore when Sounders Silence: If programmed, a zone sends
a restoral report and is ready to activate again only after the bur-
glary bell cut-off time expires or the bells are silenced.
- The zone can alarm multiple times per armed period.
• Restore when Zone Restores: If programmed, a zone sends a
restoral report and is ready to activate again as soon as it physi-
cally restores.
- This zone can alarm multiple times per armed period.
• Restore when System Disarms: If programmed, a zone sends
a restoral report when the system is disarmed.
- It can only alarm once per armed period.
• 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 trouble report will be
sent.
7.2 Zone Function Programming
• 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 DS7447 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 by-
passing (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 trou-
ble 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 panel,
this always remains as a Trouble on Open.
• Trouble on Short: This is a zone programmed to activate a trou-
ble 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 panel,
this always remains as a Trouble on Short.
• 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 (ad-
dress 0191). 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 iden-
tical to the Entry/Exit Delay #1 zone function except that it uses
entry delay time #2 (address 0192).
Note: If both entry delays have been activated, the control will
use the shorter entry delay.
• Interior Entry/Exit Follower: This is a zone programmed to be
ignored during an entry/exit delay and then become an interior
instant zone.
- If this zone is violated while the system is armed and no entry/
exit zones have been violated, it will activate an alarm.
- If this zone is violated after an entry/exit delay zone is violated,
it will follow that entry/exit delay time.
- This zone is bypassed by Perimeter Instant or Perimeter arm-
ing.
• Interior Home/Away: This is a zone programmed to become an
interior instant zone if the system is armed and an entry/exit delay
zone is violated during the exit delay time.
- If the system is armed and an entry/exit delay zone is not vio-
lated, this zone will be bypassed.
- This zone is bypassed by Perimeter Instant or Perimeter arm-
ing.
• Interior Instant: This is a zone programmed to activate an alarm
even during the entry/exit delay periods.
- It is bypassed by Perimeter Instant or Perimeter arming.
• Day Monitor: This is a zone programmed to be a perimeter in-
stant zone when the system is armed.
- When the system is disarmed, any violation of this zone will
activate the keypad sounders which will sound continuously until
a disarm command sequence is entered.
- The alarm outputs for this zone will not activate and there will
be no report for this zone when the system is disarmed.
• Keyswitch Input: This is a zone programmed to allow the sys-
tem to be armed or disarmed using a Normally Open momentary
keyswitch.
- Outputs for keyswitch LEDs and sounders are available using
the programmable outputs or the Octal relay outputs.
- An output is needed for each LED and sounder.
- A keyswitch will only control the partition that these zones are
assigned to unless programmed as a master, then they will
control all at once. See Program Address 0001, Data Digit 1.
- Keyswitches and keypads may be used in the same partition, if
desired.
• Fire Zone: This is a zone programmed to activate if the system is
armed or disarmed.
