Connect a signal tower to your network to deliver visual and/or audible notification of an alarm state to a wide area.

  1. Connect the signal tower to your network according to the manufacturer's directions.
  2. In Sites Manager on the Signal Towers tab, select Add.
  3. Complete the general configuration options:
    1. Description: Type a unique description of the signal tower.
    2. Model: Select the model number.
    3. IP address: Type the numerical IP address assigned to the tower.
    4. Port number: Choose a unique and available port number. The default port number for signal towers is 80.
  4. In Alarm Settings, select the alarm types you want to trigger signal tower alarmings.
    Use a signal tower to indicate the most critical alarm types, such as threshold and communication alarms.
  5. In Light Settings, select how to display visual alarms. Only the highest priority alarm condition will display at one time.
    • All segments: Use all available color bands to display highest priority alarm (for example, all bands will be red for a High priority alarm)

    • Priority position: Use two color bands to display a specific priority alarm, lowest priority at the bottom, highest priority at the top of the tower. If there is a High priority alarm, the top two bands display red; if there is only a Medium priority alarm, the two middle bands display orange; if there is only a Low priority alarm, the two bottom bands display yellow.

    • Priority position - inverted: It is important to consider the installed position of the signal tower - if it is hanging from the ceiling, the position of alarm colors may need to be top to bottom.

    Priority position bands can help those who are color-blind identify alarm priority.
  6. Configure the sound settings:
    • Sound/When alarms are acknowledged: Choose to enable tower sound, and whether to stop or continue tower sound signal after an alarm is acknowledged. By default, tower sound turns off only after all alarms are no longer present.
    • Alarm priorities:

      Select all of the alarm priorities that you want to initiate alarm sound on the signal tower. High alarms will always trigger an alarm sound when the sound setting is enabled.

    • Duration: Choose the length of time you want the alarm sound to be active, either a continuous loop of the selected sound pattern, or only activate sound for 5 seconds. After 5 seconds the sound will stop, but if the alarm condition still exists during the next system scan, the sound repeats for another 5 seconds.
    • Sound pattern: Select a sound pattern. To test the sounds, visit
  7. Test the connection and configuration settings. If the Test button remains disabled, check that the IP address and port settings are configured correctly.
