Newly employed alarm-LEDs enable the status display of the alarms in red, yellow and green. In case of an alarm, the central fire alarm system can react extremely quickly due to simultaneous information retrieval from all alarms or modules of a group and/or of a looped wiring system.

From the new alarm series Opal by Notifier, the short-circuit isolator is directly integrated into the fire alarm and can be controlled by the central fire alarm system. Although the diameter of the alarm chamber is now smaller in total, the new measuring chamber has a considerably higher volume. The reaction of the heat alarm can be set via the central fire alarm system at will to thermo-differential or thermo-maximal 58°C or 78°C.
