SUPERVISORY
The 3 event displays are formatted as
follows for a supervisory condition:
NN:MMM-DDD [custom message]
ACK
1 [time/date]
IN SUP
NN:MMM-DDD [custom message]
ACK
1 [device type]
IN SUP
ALARMS=0
SUPERVISORY=1
SECURITY=0
TROUBLES=0
SECURITY
The 3 event displays are formatted as
follows for a security condition:
NN:MMM-DDD [custom message] ACK
2 [time/date]
IN SEC
NN:MMM-DDD [custom message] ACK
2 [device type]
IN SEC
ALARMS=0
SUPERVISORY=0
SECURITY=2
TROUBLES=0
TROUBLE
The 3 event displays are formatted as
follows for a trouble condition:
NN:MMM-DDD [custom message] ACK
23 [trouble type]
IN TRB
NN:MMM-DDD [custom message] ACK
23 [time/date]
IN TRB
ALARMS=0
SUPERVISORY=0
SECURITY=0
TROUBLES=23
Leading zeros are not included in ad-
dresses and counts.
Additional data causes a three character
shift right, resulting in the loss of three
characters from the displayed message.
Additional data also causes a two character
shift to the right, resulting in the loss of two
characters of the device or trouble type.
The System queue totals are over 10,000
events. This expands the event number fields
to 5 digits from 3. The order of these events
is as follows:
• Queue priority (Alarm, Supervisory,
Security, Trouble ).
• Time and date of event (newest first).
• If the two previous items are identical,
the lower node number takes priority.
Global Keypad Operation
BLOCK ACK
Global block acknowledgment operates as
in a standalone MXL, but with global scope.
Events for the queue acknowledge System
wide (all nodes).
Pressing a global BLOCK ACK key results
in a broadcast XNET message to all nodes
to acknowledge all events in that queue.
Panels process the event just as if the key
press had occurred at one of its MKBs. A
success code (or error code) is sent to the
NODE that initiated the global acknowledge.
An acknowledgment message is displayed
and printed (and the appropriate LED is
updated) when the MXL determines all
events at that level have been acknowl-
edged (System wide). The time/date stamp
of an event is used to determine the true
state of the System.
LEDs are not updated unless all nodes
confirm the acknowledgment has been
successfully executed.
AUD SILENCE
This key is NOT a toggle as in a local
mode. If silenceable audibles are active
anywhere in the System, the LED flashes.
When the global AUD SILENCE key is
pressed with any/all audibles in the System
unsilenced, a global silence command is
issued. The command is processed in the
nodes as if a local audible silence had been
requested.
Command preprocessing is in place to
prevent silenceable audibles from getting
out of sync (some systems on, some
systems off) on a System basis. No
audibles will be silenced unless all can be
silenced. However, in cases where local
control is enabled, this may be unavoidable.
An error code (or success via a silence
event message) allows the global MKB to
keep up to date as to true System status. If
any panel reports an error, the display
status remains unchanged.
When the global AUD SILENCE key is
pressed with all audibles in the System
silenced, a global unsilence command is
issued. The command is processed in the
nodes as if a local audible unsilence had
