SBX IP 320 Features & Operation Guide
Alarm
The system can be programmed to recognize the status of an external contact from a relay (open
or closed). When activated, the System will signal programmed Stations with a single tone
repeated per 1-min. interval or a continuous tone. This capability is commonly employed to
provide remote alarm signals. When used as an alarm, the assigned Stations receive the
programmed signal. To stop the signal, the alarm should be deactivated (reset) from a Station
assigned to receive the alarm signal.
Operation
Upon detecting the Alarm contact, the system sends the appropriate alarm signal to assigned
stations.
To terminate the alarm signal while the line is in an idle state:
1. Dial 565; a confirmation tone sounds.
2. The alarm signal will be terminated at all assigned stations.
Conditions
• An external contact should be connected to the alarm input.
• The alarm contacts should be dry (no voltage/current source connected).
• SLT cannot receive alarm signals.
• Alarm Reset can be programmed on a flexible button.
