17.6 Cross Zoning
Caution must be taken when cross zoning devices to ensure that the Cross Zone Time is long enough to allow an
intruder to trip both devices before it expires. A Cross Zone Time that is too short may allow an intruder to trip the
devices and have just a zone fault report sent to the central station.
When a Cross Zoned zone is tripped a FAULT report will be sent to the SCS-1 receiver. When two Cross Zoned zones
are tripped within the Cross Zone Time, both zones send to the receiver as ALARM signals. For example, if zones 1
and 2 are Cross Zoned zones, and only zone 1 is tripped, a FAULT report will be sent to the receiver for zone 1. If
zone 1 is tripped and zone 2 is tripped within the Cross Zone Time, an ALARM report is sent to the receiver for zone 1
and zone 2.
17.7 Events Manager
The Events Manager function allows you to delay sending certain reports to the central station receiver. Reports can
be kept in the panel's memory until overwritten by new activity or held until the memory buffer reaches 133 events.
When the buffer is filled, the panel automatically sends the stored reports to the central station receiver. Below is a
list of panel reports that can be delayed using the Events Manager option.
17.8 Modem Setup Information
When a report is to be sent, the panel first sends "+++ATH
c
r
(carriage return)", waits one second then sends the dial
string characters entered in
MODEM SETUP
. This is followed with a space and a "
c
r
." The modem must respond to
the panel with "CONNECT
c
r
".
If "CONNECT
c
r
" is properly received from the modem, the standard HST report/response sequences occur. After a
report is sent and acknowledged, or a report is sent and not acknowledged for a period of one minute, the panel
sends "+++ATH
c
r
" to the modem.
If no response is received from the modem after 60 seconds, the cycle is repeated. Any string other than
"CONNECT
c
r
" that is returned by the modem and ends with a "
c
r
" is ignored. After three cycles and no connection is
made, a
NETWORK TROUBLE
message is sent to the central station if
UL AA
is selected as
YES
.
If the Host channel fails to receive a proper acknowledgment within 60 seconds, the panel sends a
WARNING:
NETWORK TROUBLE
(S72) report on the
2ND LINE
. The next time a report is sent by the panel over the Host
channel, the panel sends a
NETWORK RESTORED
(S73) report over the
2ND LINE
.
