The N3000-DSP10 and N3000-DSP20 are slave displays and ideally suited for use as an HMI for automation systems, e.g. for integrated alarm, monitoring and control systems (IAMCS). They are used in conjunction with the master display N3000-DMP30/31 as an extension in duty alarm systems and alarm extension systems for accommodation and mess rooms. They signal alarms at a local level, have a role to play in the engineer call and indicate measurement values and channel statuses. The N3000-DSP20 display version is equipped with an additional fire alarm call box for connecting to an external, independent fire alarm system.
