MBX IP Description / Operations & Programming Guide
Alarm Signal/Door Bell
The system can be configured to recognize the status of an external contact (normally open or
closed). The system will signal the assigned station when the contact activates. This capability
is commonly employed to provide remote Alarm or Door Bell signals to the user.
A station receives the Alarm Signal, either as a single tone burst repeated at 1-minute intervals
or a continuous tone. The Alarm Signal may be terminated at the User's phone by dialing the
Alarm Stop code, or pressing the {ALARM STOP} button if assigned. To rearm the Alarm
function, the alarm condition must be cleared and the Alarm signal terminated.
When used as a Door Bell, assigned stations receive an Alarm Signal each time the external
contact is activated; reset is not required.
CONDITIONS
- The Alarm contacts must be "dry", no voltage or current source connected.
- A station with LCD assigned to receive Alarm/Door Bell signals will show "ALARM" as
appropriate.
- If alarm is active during station busy, mute ring will be served to assigned station, and
then after conversation, when station go to idle, the alarm signal will be sent to
assigned station again.
- Assigned stations can be changed using Alarm Assign. (PGM121-Flex12)
- Only Stations assigned with Alarm ring can terminate the alarm signal.
- IP Phone and normal LKD Phone stations can be assigned as alarm stations.
- In signal mode, station will return alarm ringing again if an assigned station user does
not reset the alarm signal prior to the station returning to idle.
- When the alarm is ringing, the alarm signal must be reset so phone operation will be
fully functional (fixed or flex buttons do not operate and the user cannot hear the dial
tone during alarm ringing).
