Figure 29

Sent Alarm structure

In this figure, there is an input module that generates an alarm as a

sent. Therefore, the alarm is sent to the eKERNEL, and stored in

an alarm database (data table). Immediately after sending, the input

module withdraws the alarm, so the alarm condition is only present in

the database table, with a fixed reference to the device for which the

alarm message is meant. If the device acknowledges this alarm, the

alarm condition is removed from the database. The acknowledgment

from the device differs for each device type. If the device is an LRMS

(E2) DECT handset, and the alarm was sent as a normal message,

the acknowledgement is automatically generated at the moment

that the message arrives at the device. If the alarm message was

sent as an urgent message to an LRMS (E2) DECT handset, the

acknowledgement is received after the user presses the

accept or del

button on the handset. See Figure 32 "Acknowledge sequences for

Normal and Urgent messages using DECT handsets" (page 111).

• SET/RESET

An alarm can also be generated, based on a set command. This

command must always be followed by a reset from the same input

module, after the alarm condition is no longer active. Figure 30

"SET/RESET Alarm Structure" (page 110) illustrates the SET/REST

alarm structure.
