ceAlarmCutOff 1.3.6.1.4.1.9.9.138.1.2.4

If the management client writes a value of 'true' to this object, the agent stops signalling all external audible alarms under the control of the agent. Reading this object should always result in a value of 'false'. Observe that alarm cutoff does not have an effect on monitoring, history logging, generation of notifications, or syslog message generation. It also does not prevent the agent from signalling external audible alarms for alarms asserted after alarm-cutoff. This object emulates the 'alarm cut-off' mechanism typically installed in a central office (e.g., a big red button). Observe this object should neither affect external visual alarms under the control of the agent, nor should it affect the current state of alarms being asserted by the system.
