The panel will not allow the threshold to be raised above the measuring range for the sensor,
however the commissioning engineer should always test the detector and prove that the system is
giving proper fire protection.
5.5.3.3 Restoring Sensitivity Defaults
•
Each time the panel performs an "auto learn", it will check to see if a different type of detector has been
installed to the device type information stored in memory.
•
If so, the panel will automatically restore the pre-alarm and fire alarm settings back to the standard defaults.
•
All detector settings will be returned to default if an "Auto Learn" is performed with the sensors
disconnected.
5.5.3.4 Device Actions
•
The action taken by both smoke and temperature detectors is fixed to always give pre-alarms and fires.
•
Most other devices can have their alarm action re-defined as required.
•
This ability to change the alarm action is signified on the display by the option "Action" appearing on the
device menu when the change key is pressed. Press 6 to select the action option and the display will show
the current action assigned to the input device.
For example a call-point (pull
station) will normally show:
If the action shown is not correct for the application, press the "Change" key. Each time the "Change" key is
pressed the action will cycle through the available options. The available actions are:
Action
Fault warning
Zone Fire
Bomb Alert
Non-latching
Sprinkler Supervisory
Group Disable
not used
•
Press the Yes key once the desired option is shown.
The display will then revert to the normal device display, but will in addition show in the bottom right corner
the alarm action of the input.
For example:
The display can also be placed in this "action display" mode at any time by pressing the "6" key when viewing
any device.
5.5.3.5 Groups / Group Disablements
•
The group assignment / group disablement function allows a range of detectors and input devices to be
disabled remotely from the panel using a single input device. The initiating input device can be any loop-
input circuit, call point or peripheral input circuit.

Description
Closing the input produces a "warning" message on the display. The common
"fault" LED and the corresponding zone fault LED will also illuminate.
Closing the input puts the designated zone into fire. "True" Break Glass Call
Points / Pull Stations should ALWAYS be set to this option.
Creates a "bomb alert" from the designated zone. All NACs / relay outputs will
react according to their programming for this zone.
Allows an input device to create a temporary system event that is cleared
when the input is restored to its normal condition. This option is not normally
used on fire systems. Contact applications department for further information
before using this option.
Assigns an input to a Sprinkler Supervisory function. When the input is
closed, the FACP will light the Sprinkler Supervisory LED, sound the internal
buzzer and display an appropriate warning message on the LCD display.
Allows an input device to disable a group of detectors remotely from the
panel.
Allows an input device to be turned off. Any action or state change at the
input will be ignored.
