User`s manual
The extension (“E”) that is sent for any of the preceding is a number
1-15 (written in hex, 1-F) that is determined by the sensor/zone
number (1-16 for hardwire, and 81-112). (This extension is used as a
tool for point identification of multiple sensors and is discussed further
in Appendix B.)
The easiest way to see how the extension number occurs is to look at
the table on the right (or the example chart in Appendix B). Math-
ematically, the extension is the remainder left when dividing the
sensor/zone number by 15 (except that the remainder “0” is replaced
by 15 [“F” in hex]).
With this method and the default settings, an Entry/Exit alarm on
hardwire zone 12 would give
“1”
and
“C”
for the
“R”
and
“E”
of the
report (Report Code 1 for Entry/Exit, extension C because it is in
sensor/zone 12). The defaults (see
Fn#513)
are designed so that all
may be used and unique identification will still be provided. If you
find a need to change defaults, Appendix B discusses how to change
the defaults to provide additional sensing/reporting of any specific
type, while maintaining all, or most, of the unique reporting ability.
R
Code = 8 is a System Trouble. These are the extension codes that specify which trouble:
Extension E is:
0 for RF module
4 for Phone Line Failure
B for RF Sensor Supervision
1 for CCU Low Battery
5 for AC Power Failure
C for Fire Trouble
2 for Suspend Operation
7 for Hardware Trouble
E for RF Sensor Low Battery
3 for Over-current Protection Failure
R
Code =
9
is
a Sensor/Zone Bypass restore report. The Extension is the number of the zone, just as for
code 0.
Group bypass is indicated by separate bypass reports for each sensor/zone.
R
Code =
R
is an opening report, and the Extension indicates the User number (the number 1 through 15
given to users when an access code is assigned). Users 1 through 9 and 11 (B) through 15 (F) will be
represented by their numbers. User 10 and the keyswitch and RF keypad will be represented by a
“0”
or “A”
depending upon the type of receiver.
R
Code = C is a Closing report, with the User identified in the same way as for Code B.
R
Code =
D
is a Cancel report, with the User identified in the same way as for Code B.
R
Code = F is a System Trouble Restoral. Its extensions are identical to
R
Code 8 except that they represent
a
restoral
instead of a trouble.
R
Code = F is for Other Reports. An extension of 1 is an Automatic Test
report.
2 is a Manual Test report
4 is a History Buffer Full* report
3 is an Alarm Restore report
*
History Buffer Full is sent when there is room for 4 more items, and when totally full.
