WARNING
Prior to carrying out any work ensure local regulations and site procedures are
followed. Never attempt to open the detector or enclosure base when flammable
gas is present. Ensure that the associated control panel is inhibited so as to
prevent false alarms.

4.1 Operation panel

The Xgard Bright operation panel comprises an OLED screen, a three-colour status
LED and two magnetically operated Hall Effect switches. The screen displays white
characters on a black background and can be viewed clearly even in bright sunlight.
Reversed white screen saver will be activated in normal detection condition if there is no
activity for a long time.

4.2 Screen Indications

When the Xgard Bright is powered up, the unit will perform internal diagnostic checks
whilst the display will show a Crowcon logo. This procedure will be displayed for about
45 seconds followed by displaying a warming up status for about 120 seconds.
