The Receiver extension monitors the connection
between Security Center and an alarm receiver by
listening for a heartbeat message. You can change the heartbeat timeout and enable or disable
heartbeat notifications.
Before you begin
If you enable heartbeat notifications, make sure that the receiver is configured to
send a heartbeat message. Each manufacturer refers to the heartbeat differently, it might
be known as the "polling timeout", "polling frequency", "watchdog timeout", or "heartbeat".
Refer to your manufacturer's documentation for details and instructions.
What you should know
- The heartbeat timeout applies to receivers from all manufacturers.
- When a receiver fails to send a heartbeat within the specified period, a Unit
lost event is triggered and the receiver goes offline (red) in Security Center.
- Heartbeat notifications are only reported for Bosch alarm receivers.
Turn on
heartbeat notifications when you first add a Bosch receiver to Security Center, when you are making changes on
the IP network, and when updating or reconfiguring receivers in the field. When
the receiver heartbeat notifications are ON, the event Receiver: Bosch internal
message - Acknowledge (Intrusion detection unit) is logged for each
heartbeat message received.
Tip: To find out when a receiver last communicated with Security Center, generate a Receiver
activities report for the custom event Receiver: Bosch internal message
- Acknowledge (Intrusion detection unit).
Procedure
To change the heartbeat timeout:
-
From the Config
Tool home page, open
the Intrusion detection task.
-
In the entity tree, select the alarm receiver.
-
Click the Properties tab.
-
In the Heartbeat timeout field, enter a period of time. The
default is 2 minutes.
Tip: To avoid false alarms, set the timeout to a value that exceeds the
heartbeat frequency set on the device. Also consider the time it takes for
messages to traverse your network. For example, if the device sends a heartbeat
every 30 seconds, set the Heartbeat timeout to 40 seconds
or more. If there are times when the traffic on your network peaks, make sure the
timeout is long enough to accommodate those busy periods.
-
Click Apply.
When the extension does not receive a heartbeat message from a receiver
after the timeout period is exceeded, the intrusion detection unit is displayed as
offline (red) in the Intrusion Manager role of Config
Tool. When the next heartbeat message
is received, the receiver is put back online.
To receive an event in response to a heartbeat message:
-
In the Notifications section, set the Receiver
heartbeat slider to ON.
-
Click Apply.
To silence the event in response to the heartbeat
messages:
-
In the Notifications section, set the Receiver
heartbeat slider to OFF.
-
Click Apply.
