Redundant class-A loop integrity monitoring and self-healing
The addressable loops of the Draco panel can be connected in stubs (class B) or looped (class A) topologies.
When more than 32 initiating devices are connected to the loop, class A topology shall be used and JBE-
2150 isolators shall be installed in the loop to limit the consequences of a short circuit in the loop.
Wiring topologies in class A provide a redundant connection with loop devices. This is the topology with the
highest robustness to wiring faults.
Output group activation:
In response to fire alarm events, up to 400 output groups can be activated with or without programmed
delays. The Draco panel meets the optional requirements regarding outputs to:
-
Fire alarm devices (outputs assigned to group 001-SND)
-
Fire alarm routing equipment (outputs assigned to group 002-FR).
These two output groups implement the corresponding EN 54-2 requirements regarding programming,
supervision and indication. The remaining 398 groups are freely programmable.
Dependency on more than one alarm signal (type C coincidence detection)
Thanks to the advanced programming menu, the activation of outputs can be linked to the reception of more
than one alarm. In this configuration the panel indicates alarm normally, but the activation of outputs is
inhibited until a second alarm signal is received from another initiating device. Confirmatory signals may
come from detectors or manual call points in the same or another zone.
Day/Night modes of operation
The day/night schedule allows adjusting the fire detection settings to the activity of the building. At the
scheduled times, the fire panel can activate or deactivate delays and change the sensitivity of each detector
independently. The scheduled activation and deactivation of delays is compatible with a manual activation
or deactivation.
Three sensitivity profiles (Day, Night and Special) can be programmed and assigned to the weekly time
periods. This allows selecting the most convenient sensitivity for each detector in each moment of the week.
