extinguishant-
system button
Supervised. The STOP extinguishant-system button
should always be located near to the
protected area. This will allow any
persons present during the release of
extinguishant gas to stop the process
and evacuate the area unharmed. Up
to 20 devices can be connected to this
input.
PRESS Gas extinguishant
pressure switch.
Supervised. The pressure switch has two functions:
- Under normal operating conditions, it
monitors the pressure of the Gas
extinguishant. If the pressure drops
spontaneously below the pre-set value,
it will generate a fault signal.
- After an 'Extinction' command, it
confirms that the command has been
executed.

PRE-EXT Audible and Visual
signaling devices
Supervised The signaling devices activate as soon as
the detectors sense fire conditions that
require gas extinguishant intervention.
This will allow building occupants to
evacuate the building before the gas
extinguishant is released. The delay
between the activation of alarm signaling
devices and the release of the gas
extinguishant is customizable.
