Configuring Alarm Center Communications 163
Note:
Make sure that this number is sufficiently high. If the Alarm
Center is connected to another base station, if it is sending an email
over its modem, or if an APS is in use, the dial-up will fail and the
base station must retry. The more base stations using the same Alarm Center,
the more retries are needed. You can have up to 20 retries. If the base station
is connected to an APS, specify 20 retries and minimize mass dial-out attempts
by enabling dialling out on only two base stations for conditions that can be
guaranteed to affect all base stations (for example, AC mains failure).
9. In the Time between retries box, specify the length of time that the base
station will wait before trying again to connect to the Alarm Center.
10. In the Minimum interval box, specify the minimum time that must elapse
after the base station sends an alarm log or email message before it can send
another. Select a number and specify whether it is minutes or hours. Make
sure that the interval is large enough to prevent the base station keeping the
Alarm Center busy when other base stations are trying to contact it.
11. Click OK to confirm your changes and close the form.
12. Create suitable Task Manager tasks that instruct the base station to send the
alarm log or status message, using the action Send alarm log now .
Configuring Port Switch Commands and Responses
If the base station is connected via an APS, set up the port switch commands
and responses as follows.
1. In the Connect command box, enter a command in the format
^M/Cx^M, where:
^M instructs the APS to enter command mode.
/C requests a connection
x is the APS port that the site modem is connected to. This is usually the
highest port number available.
^M terminates the sequence.
2. In the Connect response box, leave the default value ‘1’. This is the
message that the APS uses to acknowledge the base station’s connect
command.
3. In the Disconnect command box, enter a command in the format
^Mxxx^M/X^M, where:
xxx is a sequence of three identical characters, for example, LLL. The APS
must be configured to recognise the same character for its disconnect
sequence and to require three sequential characters.
/X^M is the command mode exit instruction.
4. In the Disconnect response box, leave the default value ‘3’. This is the
message that the APS uses to acknowledge a disconnect command.
