Overview
The illuminated warning signs provide a clear, visual and audible warning for a variety of applications.
Standard units are available to provide warning of a fire alarm or extinguishant release but the display may
be customised to show any text on several coloured backgrounds.
Warning signs have two levels of operation in which the top and bottom halves of the sign may be split to
show an initial warning and then additional text for a reinforced warning, or if required both halves can be
activated at once.
The two levels may be activated either by a common and two switched signals, or by the Serial 485 bus
from the Sigma XT control panel.
Up to 7 devices can be mixed along with status units and ancillary boards when utilising the serial bus. The
serial bus connected units require a 4 core connection comprising 24V DC supply and the communications
bus.
The signs are suitable for Fire, Extinguishant, Security and any other type of alarm system, and have a wide
operating voltage from 15 to 30 Volts DC making them suitable for a wide range of applications.
The use of high brightness, white LED indicators minimises power consumption and maximises reliability.
