Alarm Indication Modules
A local alarm display is invaluable to alert staff within a clean room that critical parameters are out of limits. The stainless-steel plate and wipe clean surface allow installation in high classification areas, offering information right where it is needed. A bright red lamp indicates the presence of one or more parameters that are out of compliance within the local area. A sounder announces the arrival of a new alarm condition and continues to sound until silenced by pressing the ‘Mute’ button. This means that operators are made aware of potential problems at the earliest opportunity and can take appropriate action without leaving the clean room.
