Display modules provide real-time indication of the status of a VESDA detector. They have a 20 segment vertical bar graph display, a 2 digit numeric display, an audible sounder, clear alarm and fault indicators. They also have 4 push button keys to control the detector and the mode of the display.
The Display Module can be mounted into a detector unit, a remote mounting box or a 19in sub rack. Several displays can be configured to display information from a single detector in multiple locations.
There are various versions of the display module depending on the type of detector and the relay configuration required. The LaserSCANNER display has a fourth mode for the numerical display which shows the First Alarm Sector (FAS), this being the number of the sector (pipe) that has detected smoke. For the LaserCOMPACT the Fire 2 LED is omitted.
