Noby UK Noby-220 2-Zone - Manual (Page 2)

The Noby-220 is supplied as a fully functional fire alarm panel with comprehensive fault
monitoring to meet the requirements of the EN54 standard. The following programmable
disablement options are provided as a tool to assist the installer in fault finding, such as
compatibility issues with 3rd party detectors and sounders. The installer should be aware
that the permanent use of these disablement options may have a bearing on the overall
safety and approval status of the system. Any permanent setting of these options is
undertaken solely at the risk of the installer.
With the panel in normal quiescent standby state:
! Enter the 8 digit Engr Code - confirmed by the green Power LED flashing rapidly.
! Enter the appropriate Select key (see table below).
! The LEDs surrounding buttons 1 and 2 indicate the current option status.
! LEDs on = option set; LEDs off = option cleared (factory default).
! Toggle button or button as required
! Press to accept the currently displayed status OR
! Press to quit without updating the option status.

Panel Behaviour
Audible Alarms, Faults & Warnings
In the event of a fire alarm the internal piezo sounder emits a loud rapid pulsing tone, and
any externally connected sounders are also activated, together with the fire alarm relay.
All circuit and system faults are accompanied by a fault tone i.e. a double beep every 4
seconds.
A warning tone is signified by a double beep every 60 seconds. This is most likely to occur
when there is loss of mains supply or a power-cut lasting longer than 90 seconds.
Mute
All audible sounds can be muted by pressing the button.
System Reset
A System Reset resets the detector circuits and clears down the panel indications. All the
panel LEDs are lit during the 3 second reset period. Note that a standing fire or fault
condition will immediately re-trigger the alarm after a Reset.
Courtesy Light & Power-Cuts
Under normal circumstances the courtesy light can be switched on for a self-timed period
of 10 minutes, or switched on permanently by means of the User Access Code. In the
event of a power-cut the courtesy light self-timer is extended to a more useful 60 minutes,
and is automatically triggered on detection of mains power loss. At any time during a
power-cut the light can be manually re-triggered for a further 60 minute period. Note that
in the interest of conserving battery power it is not possible to turn the courtesy light on
permanently during a power-cut.
Backlight
The backlight is automatically disabled in the event of mains loss in order to save battery
power.

Troubleshooting
The green Power LED is not steady
Check that the mains supply is connected and switched on.
The Common Fault LED will not clear
Refer to the LED Indications to determine the cause of the fault.
The Common Fault indications are listed in order of priority.
Ooops, I accidentally connected the battery the wrong way round
We've all done it at some time or other ! Replace fuse F2 (T1.0A) and try again.
A detection device generates a fault instead of a fire
Some (older) detectors and call-points are not compatible with modern panels equipped
with short circuit fault monitoring. One remedy is to connect a resistor in series with each
affected detector head - any value in the region of 400 to 1000 ohms is suitable. Some
detector bases allow spare terminals for this purpose. Care must be exercised not to
inadvertently insert this resistor in series with the main cable run, as this will lead to other
erratic behaviour.
Another work-around is to set the programmable option Disable Detector S/C Fault
Monitoring - see Programmable Options. In this case all detector short circuits are
interpreted by the panel as a fire condition.
There's a persistent zone fault that can't be cleared
! Check all the detector heads are both present and securely located to their bases.
! Check base connections, paying particular attention to correct polarity.
! Check that the EOLC is fitted across the final detector.
! Check that the detector bases are of the schottky diode type.
! Programme the option to Disable Detector Head Removal Monitoring - if this clears
the fault then the problem is likely to be related to one or more bad detector
base/head connections. Note: setting this option also disables o/c monitoring and is
therefore not recommended as a permanent fix - the purpose of the option is to help
eliminate one possible cause of a fault.
! Failing the above suggestions, it's down to the systematic process of elimination ie.
relocate the EOLC to the first device and disconnect the remaining detectors, then
move onto the second device etc.. Repeat until the fault shows up.
There's a persistent sounder fault that can't be cleared
Check that the sounders are the polarised type and compatible with conventional fire
panel fault monitoring. Check the cable connections at each sounder for correct
polarity, and that the EOLR is connected across the final sounder.

Some functions are accessed by a simple one-touch key operation, whilst other
more safety critical functions are accessed via the User Access Code.
The acceptance of each key sequence is confirmed with an audible double click.
When entering the User Access Code, the green Power LED will flash rapidly for 5
seconds signifying that the panel is ready to accept the Function key.
