Available AHS License options are:
SG-CPM5-250KAHS
AHS table expansion to 250,000. This license is included when the SG-SYS5MEM4 is installed.
NOTE: Additional SG-CPM5-250KAHS licenses can be purchased to expand the AHS table in increments of 250,000 up to a maximum of
1,000,000 entries.
5.4 Automation
5.4.1 Automation input/output
Traditional automation communication is provided via port 1025 (default) on the Ethernet connection and/or the serial port. This port is a Sur-Gard stand-
ard output and provides Sur-Gard standard automation output. Each CPM can be expanded to 4 SG-TCP automation port connections through SG-
CPM5-AUTO license. The connection status of all automation ports is sent to the SG-System 5 Console and are monitored independently for con-
nection status.
5.4.2 Automation compatibility
Central station automation software packages support the SG-System 5 Sur-Gard interface. Refer to automation software specifications for com-
patibility.
Examples of supported automation software packages:
l
MAS
l
DICE
l
SIMS II
l
GENESYS
l
S.I.S.
l
IBS
l
MicroKey
l
Bold
NOTE: Automation connections are considered supplementary per UL864 Listing. Compatibility with the automation software in a system
used at a central station is intended to be handled under a separate UL1981 software and/or site certification evaluation.
5.4.3 Automation protocols
The SG-System 5 receiver sends ContactID and SIA to report signals to the central station computer via a TCP/IP and/or RS-232 serial port.
5.4.4 Acknowledgment of the signal
The SG-System 5 receiver requires an acknowledgment signal [ACK] (Hex 06) from the computer software within four seconds for each message sent.
Failure to receive the [ACK] results in retransmission of the signal. After the fourth attempt, the SG-System 5 indicates a communication failure on the
automation port. During a communication failure the SG-System 5 receiver stops transmitting except for the heartbeat. In case of communication failure
with the computer, each SG-DRL5-IP can store up to 2500 events in its internal memory and the SG-CPM5 can store 50 events for its own internal
events. Communication is resumed when the first heartbeat acknowledgment is received; all buffered information is then transmitted.
5.4.5 COM responses
When the SG-CPM5 sends an event to the computer, it checks for three responses: ACK, NAK or Unknown/No Response. An ACK indicates that the
computer automation received the event successfully. A NAK indicates the computer automation received the message but didn't understand it. The line
card attempts to send the message 26 times. If after the 26th attempt it receives a NAK from the computer automation, the SG-DRL5 generates an
internal communication error. The SG-CPM5 sends the internal communication error event to the printer and outputs the message to the printer in
ASCII, and attempts to move onto the next signal. Any other response from the computer automation, including no response, causes the SG-CPM5 to
attempt to resend the message up to four times. If after four attempts the SG-CPM5 does not receive a response or receives an unknown response, it
assumes nothing is connected, generates an alarm and falls to the next active automaton port or manual mode.
5.4.6 Automation absent
When the computer is not responding to transmissions, the SG-CPM5 generates a 'SG-Serialx fail' or 'SG-TCP/IPx Fail' trouble. When the trouble
occurs, the SG-CPM5 continues to attempt to send a heartbeat signal to the computer until it gets a response. The SG-System 5 receiver makes four
attempts, then waits for the next heartbeat period before making another four attempts. The typical heartbeat interval is 30 seconds.
