Ack Required for Off-Normal,
Fault, and Normal

Requires a control module acknowledgement for each
message type. Normally not required.

TIP

To require operator acknowledgement for an Alarm

or Return-to-normal message (stored in the WebCTRL
database) change the acknowledgement settings on
WebCTRL's

Alarm > Enable/Disable

tab for an alarm

source or an alarm category.

Recipient List

Recipients

The first row in this list is the WebCTRL Server. Do not
delete this row. Click

if you want other BACnet

devices to receive alarms.

Recipient Description

Name that appears in the

Recipients

table.

Recipient Type

Use

Address

(static binding) only for third-party BACnet

device recipients that do not support dynamic binding.

Recipient Device Object
Identifier

Type the

Device Instance

from SiteBuilder (or from the

network administrator for third-party devices) in the

field.

Process Identifier

Change for third-party devices that use a BACnet Process
Identifier other than 1. WebCTRL processes alarms for
any 32-bit Process Identifier.

Issue Confirmed
Notifications

Select to have a device continue sending an alarm
message until it receives delivery confirmation from the
recipient.
