Model LCD-240/1G

General Description

The LCD-240 was designed for use on a fire alarm system printer port. The
unit displays the same information the would be printed on a printer. When em­bedded in a Graphic Map, the LCD-240/G provides complete annunciation
without using LEDs or lamps.

Each alarm initiating device will be shown on the graphic map, along with its
corresponding address. When an alarm occurs, the unit will display the alarm
addresses, and a descriptive message. The address shown on the LCD dis­play is then correlated to the device location on the map.

Ordering Information

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.

Graphic sizes are shown below, according to model number. 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.

Please complete the annunciator Order Form and send with drawing. If Order Form is not available, indicate how annuncia­tor will be activated and list any specifications required.
