6.0 System Overview
6.1 DS7400Xi Description
The DS7400Xi Control/Communicator is a fully integrated hardwire/
multiplex security/fire alarm system.
- It can support up to 128 input zones, 90 individual users, and
multiple output options.
- It can be partitioned into as many as eight separate systems,
thus allowing individual control and reports for each partition.
- Up to 15 keypads may be used to provide user interface with
the system, as well as programming access for the installer.
6.1.1 A/C Failure Report Delay
The A/C power loss report can be programmed to delay for up to
254 minutes (see address 0197). (The same delay would also apply
to the A/C restoral report.)
- If another report is sent during this delay period, the A/C fail
report will be sent along with this report.
- If the A/C power restores during this delay period, the A/C loss
report will not be sent.
- Programming address 0197 as FF causes the report to be sent
at a random interval of at least 15 minutes, but no more than 2
hours after the A/C failure occurs.
6.1.2 Entry/Exit Delay Cancel Zone Functions
Entry/Exit Delay Cancel 1 and Entry/Exit Delay Cancel 2 Zone Func-
tions cause the exit delay to expire as soon as the premises is va-
cated.
- If a zone is programmed as an Entry/Exit Delay Cancel zone,
and it is activated during the exit delay, the exit delay will expire
as soon as the zone has been restored.
- Entry/Exit Delay Cancel 1 follows entry delay 1.
- Entry/Exit Delay Cancel 2 follows entry delay 2.
- They are programmed at addresses 0001-0015.
6.1.3 General “Arm-Only” Authority by Partition
A general (level 2) authority can be programmed to have arm-only
authority by partition. This is done at addresses 0198 and 0199.
- Arm-only access by partition allows someone with a General
Authority to arm and/or bypass zones in a partition he can not
disarm.
- This level can still be used to arm, disarm, and bypass zones in
the other partitions that it has access to.
6.1.4 Input/Output Cross Matrixing
Input/Output Cross Matrixing allows Output Functions to follow the
status of specific input zones (zones 1 through 99 only).
- Outputs can be programmed to follow any combination of one
or two zones, open or closed, with the system armed or dis-
armed.
- If programmed to latch, the output will latch until a valid PIN is
entered at the keypad.
6.1.5 Multiplex Bus Outputs
The DS7400Xi supports up to 20 DS7465 Input/Output Modules.
- These modules are connected to the multiplex bus and provide
one input loop and one Form “C” output relay.
- The input loop operates the same as all other multiplex inputs.
- The output loop can be programmed to follow Output Func-
tions.
- Multiplex Bus outputs can be bypassed using the bypass func-
tion. If an output zone is bypassed while it is ON, it will turn
OFF. The bypass will not be removed when the system is armed
and then disarmed; it must be cancelled by entering the bypass
command again or by cancelling all bypasses.
Note: DS7465 Module outputs will not pulse, even if programmed
to do so.
6.1.6 Octal Relay Modules (DS7488)
The DS7400Xi can support two Octal Relay Modules.
- Each relay can be programmed to follow system-wide events
or Output Functions as described above.
6.1.7 Output Functions
Output Functions can be programmed to follow system events or to
follow one or two specific zones in a “cross-matrix” fashion (see
Input/Output Cross-Matrixing).
- These Output Functions can be programmed to control Octal
Relay outputs or Multiplex Bus outputs.
- Output Functions are programmed at addresses 1472 through
1516.
6.2 Zone
A Zone is an input to the DS7400Xi Control/Communicator.
- There are 8 hardwired zones on the main circuit board.
- Additional zones may be added by using the DS7433 (8 zone
expansion module), the DS7430 (multiplex loop module), and/
or other modules.
6.3 Zone Function
A Zone Function is the description of how a particular zone will be-
have (e.g. steady alarm output, bypassing allowed, alarm on short,
trouble on open, perimeter instant).
- Zone functions may be custom made, but 8 default zone func-
tions already exist.
- There are many possible zone functions, but only up to 15 dif-
ferent zone functions are allowed per control.
- Each zone must be programmed as a specific zone function.
Any number and combination of zones may be programmed as
particular zone functions.
7.0 Glossary
7.1 General Control Programming
• Normal Arming - [PIN] + [On]: If programmed, arms the entire
system while allowing entry delays for entry/exit zones.
• Perimeter Instant Arming - [PIN] + [No Entry] [Perimeter Only]:
If programmed, arms only the perimeter of the system and does
not allow entry delays for entry/exit zones.
• Perimeter Arming - [PIN] + [Perimeter Only]: If programmed,
arms only the perimeter of the system while allowing entry delays
for entry/exit zones.
• Custom Arming - [PIN] + [#] [4]: If programmed, allows custom
arming of the system and bypasses the zone functions specified
in data address 0183.
• Maximum Security Arming - [PIN] + [No Entry] [On]: If pro-
grammed, arms the entire system and does not allow an entry
delay for entry/exit zones.
• Closing Ring-Back: If programmed, the keypad sounders and
Bell will activate for 2 seconds after the system is armed and the
closing report is successfully sent. This requires Closing Ring-
Back and Closing Report to be programmed.
- If a closing report is not programmed, the control will test for a
dial tone when the system is armed. If the test passes, the sys-
