- It can be silenced (not reset) by entering a valid [PIN] + [Off].
- The display will indicate a Fire Alarm for this zone on all key-
pads in every partition.
- A fire reset command must be entered after silencing the alarm
to re-enable this zone.
- If this zone is programmed for trouble and the loop opens, the
DS7447 keypad will display “Fire Trouble” for this zone and the
keypad sounders will beep once every ten seconds.
- If the system is a combination fire and burglar alarm, the fire
alarm has priority over the burglar alarm.
• Fire Zone with Verification: This zone is identical to a Fire Zone
except that after the first alarm, it will perform a fire reset and then
wait up to two minutes for a second alarm.
- If a second alarm occurs within this two minute period, the sys-
tem will indicate a fire alarm.
- If there is no second alarm within this two minute period, the
control panel will reset back to its normal condition.
Note: Use of this control’s alarm verification feature is not per-
mitted for applications in the state of California.
• Water Flow Zone: This is a zone programmed to operate like a
Fire Zone, but is specifically intended for water flow switches.
- An optional retard timer can be programmed to compensate for
changes in water pressure. If the timer is used, the water flow
zone must be activated for the complete time period; an alarm
will be initiated at the end of the timer period.
- The maximum combined water flow delay of the control panel
and the device must not exceed two minutes.
Note: Any zone can be a water flow zone, but only zones 1
through 4 may be programmed as delayed water flow
zones.
• Supervisory Zone: This is a zone programmed to accommo-
date shut-off valves.
- It will indicate a supervisory condition at the keypads when ac-
tivated.
7.3 Zone Programming
• Single Zone Input: This is an individual zone such as the on-
board zones and multiplex contact zones.
• Multiple Zone Input: This is a zone connected to one of the 8-
Input Modules or to a Dual Zone Module.
- The inputs are programmed separately (see the separate Pro-
gramming Addresses Worksheet, P/N 29802).
- When using the Dual Zone Module, loop A is always pro-
grammed as an odd numbered program address (ending in 1,
3, 5, 7, or 9). Loop B is the even numbered program address
that follows loop A.
• DS7465: This is the input zone or the output relay on a DS7465.
The odd numbered zone is programmed for the input zone func-
tion and the even numbered zone is programmed for the output
function.
7.4 Output Programming
• Latch on Any Zone Alarm: This is an output programmed to ac-
tivate upon any zone alarm (including invisible zones) and will
latch until the system has been disarmed.
- If this output responds to a fire zone, it will remain latched until
the fire reset command is performed.
• ON during Entry Pre-Alert: This is an output programmed to
activate when an entry/exit zone is violated while the system is
armed.
- It will remain activated until the system is disarmed, or until the
entry delay time has expired.
• ON for 10 seconds after [PIN] + [System Reset] is entered: This
is an output programmed to activate for 10 seconds after the fire
reset command is entered at the keypad or if a Fire Zone with
Verification activates.
- This output is intended to be used to power 4-wire smoke de-
tectors or any other device that requires a power interruption to
reset an alarm condition.
Note: When Programmable Output 2 is programmed this way, it
will normally supply auxiliary power and will turn OFF for
10 seconds when the fire reset command is entered.
• ON when System is Armed: This is an output programmed to
activate when the system is armed.
- It will remain activated until the system is disarmed.
• Ground Start: This is an output programmed to activate for 3
seconds when the phone line is seized. It is intended for use with
ground start phone systems that require a momentary short to
ground to obtain a dial tone.
- Connect a separate 12 VDC, DPDT relay.
- Connect both relay contact commons to ground, and connect
the Normally Open of each contact to terminal positions 13 and
16 (one to terminal 13, the other to 16) of the DS7400Xi.
- This output follows all partitions regardless of how data digit 2
of the output programming address is programmed.
- Not intended for U. L. Listed systems. Not for use with phone
line monitors.
• System Status (ready to arm): This is an output programmed to
follow the Status LED of the keypad.
- It will activate when the system is ready to arm with no zones
violated.
• Zone Alarm: This is an output programmed to activate when a
zone is in an alarm condition.
- It will remain activated until the system is disarmed or the bell
cut-off time expires.
- This output is intended to activate alarm bells and sirens.
- This will not activate from Silent or Invisible Zones.
• Zone Alarm Delayed by 20 sec.: This is an output programmed
to wait 20 seconds after a zone enters an alarm condition to acti-
vate.
- It will remain activated until the system is disarmed or the bell
cut-off time expires.
- This output is intended to activate alarm bells and sirens, but
provides a delay to allow the user to silence the system before
it activates.
• Keypad Sounder Output: This is an output programmed to fol-
low the keypad sounder.
- It activates during the entry pre-alert and during any day moni-
tor alarm. It does not follow momentary keypad beeps such as
keystrokes, chimes, etc.
• Access Output: This is an output programmed to activate for 10
seconds when an access control PIN is entered at the keypad.
- Not U. L. Listed for Access Control (UL294).
