GRAPHIC ANNUNCIATOR

LD-2 (Shown Below)

General Description

Our Graphic Annunciator, the LD series,  is housed in a sturdy Brushed Aluminum frame and attached to its backbox with a vandal resistant “hidden” hinge. It is key-lockable to prevent unauthorized access.

Terminal strips, mounted inside the door, facilitate the wiring of Field Devices. Screw connectors are complete with captive wire protection and are automatically secured against loosening.

Each LD series annunciator can be customized to accommodate most any lamp driver module you can provide. It can accept anything from the LDM-32 by Notifier to the SIM-16 by Siemens and almost anything in-between. We interface your lamp driver module with our door though factory installed and wired circuit boards.

A Green LED will indicate that the annunciator is properly powered and in standby.  All units come standard with a lamp test, most commonly a push button switch. When activated, ALL system indicators should light as a demonstration that all internal circuits, wiring and LED’s are functioning properly.

*A drawing is required showing the actual graphic representation needed for your project. The exact location of the indicator points should be shown and identified by a legend. Mark the Annunciator location on the plans so that the artwork can be oriented properly with a “You Are Here” designation.

**The maximum area available for artwork is the outside dimension, less two inches. We will work from your blueline, copy, fax, sketch, email or CAD file. Please note: a full size, inked mylar, from your CAD drawing, will speed production.

 

Note: For Semi-flush mounting, add 3” to overall “W” and “H” dimensions. Consult the factory regarding custom sizes, products, options or special requirements.
