The “Extinguishing agent flow” option lets you define the functionality of this
device. Here are the details.
When the extinguishing agent flow option is set to OFF, the panel enters the
extinguishing released state when the actuator output is activated. The panel
does not require confirmation of the flow to enter this state. The extinguishing
agent flow circuitry continues to operate for indication purposes. The panel will
not enter the release state when the extinguishing agent flow device is active
without first entering the extinguishing activation state (that is, when an
extinguishing event is detected).
When the extinguishing agent flow option is set to ON, the control panel can
enter the extinguishing released state from any state, once the extinguishing
agent flow device is activated. In extinguishing released state, the panel activates
all corresponding outputs, except for the actuator output.
Connecting a safety door fault monitoring device
The safety door fault monitoring input lets the panel monitor a door in the
extinguishing area. The monitored door becomes a
safety door
.
A safety door fault means that the door is in a position that will prevent the
release process, given the current operating mode of the panel. A safety door
fault prevents the panel from entering the extinguishing activation state (because
of life safety issues) and activating the actuator (to ensure property protection).
When the panel is in manual-only mode, the safety door must be open. A closed
door signal is interpreted as a fault.
When the panel is in manual-automatic mode, the safety door must be closed.
An open door signal is interpreted as a fault.
You can configure a delay before the panel interprets a safety door monitor
signal as a fault. This allows for momentary opening or closing of the door for
routine traffic. The delay is bypassed when the panel enters the extinguishing
activation or extinguishing released states.
By default, the control panel is configured for basic applications which do not use
this monitoring function. If your installation requires it, activate the function by
setting the “Safety door monitoring” option to ON, and specifying a “Safety door
fault delay” between 10 and 90 seconds.
Here are the operating details of the function.
When the panel is not in extinguishing activation or extinguishing released states:
• For manual-automatic mode, the panel reports a fault if the door is open and
the door fault delay expires
• For manual-only mode, the panel reports a fault if the door is closed and the
door fault delay expires
When the system is in extinguishing activation or extinguishing released states,
no matter which operating mode, the panel reports a fault if the door is open.
