Example of Retry Count: 
An acknowledgment of the heartbeat was not 
received within 10 sec. The control panel sends the 
next Heartbeat Poll after the first 10-sec ACK wait 
period expires. If the central station does not 
acknowledge this Heartbeat Poll, the control panel 
continues to re-send. When the resend count is 
reached, the control panel declares this path as failed 
(and generates the Comm Trouble ## Event). The 
control panel continues to re-send the Heartbeat Poll 
at the original poll rate time until it receives an 
acknowledgment, even after declaring a Comm 
Trouble.  
When the control panel receives acknowledgment 
from the central station, the control panel returns to 
the normal Poll Rate (which, in this example, is 120 
sec). 
If more than one SDI Path is used, the control panel 
handles them on a successive basis. For example, if 
acknowledgment from SDI Path 1 is not received 
within 10 sec (using the previous example), the 
control panel moves to SDI Path 2 to send its 
Heartbeat Poll (and subsequently waits for the ack) 
before returning to SDI Path 1 to re-send its 
heartbeat. 
 
If Heartbeat Polls are enabled to send by 
an SDI path, and the Path # Ack Wait 
time is exceeded, a COMM TRBL SDI ## 
event occurs. When this condition occurs, 
all events routed to this path go 
immediately to the backup path 
destination. 
Entries are made in one-sec increments. 
 
 
5 min = 300 sec 
1 hour = 3600 sec 
12 hours = 43,200 sec 
18 hours = 64,800 sec 
Path # Ack Wait 
Default: 
13 
Selection: 
5 sec to 65535 sec 
5 to 65535 
The control panel waits this amount 
of time to receive an 
acknowledgment from the central 
station. 
Determines how long the control panel waits for an 
acknowledgment from the central station after a 
Heartbeat Poll or an actual event was transmitted. 
This prompt is applicable to SDI transmitted events 
and Heartbeat Polls. Entries are made in one-sec 
increments. 
 
 
Path # Retry Count 
Default: 
Selection: 
0 to 255 
COMM FAIL RG# SDI ### Events 
are not generated. 
1 to 255 
COMM FAIL RG# SDI ### Events 
are generated after resending 
Heatbeat Poll the number of times 
selected for a given SDI path. 
Determines how many times the control panel 
resends the Heartbeat Poll before declaring a path 
failure and generating a COMM FAIL RG# SDI ### 
(RG # = 1 to 4, SDI ### = 88 for Path 1, 89 for Path 
2, 90 for Path 3, 91 for Path 4) Event. 
If using IP Addresses as the 
communication means for UL 864 
Commercial Fire applications, program 
this parameter as necessary. 
The default settings meet or exceed the 
UL specifications. 
5.5.1 
Ant-Replay Security Feature 
The Anti-Replay feature is always enabled in the 
control panel and must be supported by the central 
station receiver. 
Anti-replay is a strategy that counters “replay” 
attacks. This feature prevents a malicious attack that 
substitutes a control panel or another network 
interface module (NIM) from delivering counterfeit 
events over a network in place of events sent by the 
actual control panel. A replay attack occurs when 
someone records a message sent over the network 
by Device A, and replays this message at a later time 
while pretending to be Device A. 
5.6 SDI 
RPS/Enhanced 
Communications Configuration 
This section provides the necessary prompts for 
configuring the SDI-Network Interface Module (NIM) 
when using it for SDI RPS or SDI enhanced 
communication applications. 
 
Supervise SDI 88 
Default: 
No 
Selection: 
Yes or No 
Yes 
Supervise the network interface 
module (NIM) at SDI address 88. 
No 
Do not supervise the network 
interface module (NIM) at SDI 
address 88.
