Panel Behaviour

Audible alarms, faults & warnings

In the event of a fire alarm the internal piezo sounder emits a loud rapid pulsing tone, and the external
sounder circuit is activated, together with the fire alarm relay (if it has not been re-programmed as a fault
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 60s and is most likely to occur when there is loss of the
230VAC supply or 230VAC Mains Loss condition lasting longer than 90s.

Panel Reset

A Panel Reset attempts to reset the detector circuits and clear the latched LED indications. All the panel
LEDs are lit during the 3 second reset period. Note that a standing fire alarm or fault condition will
immediately re-trigger the sounders following a Panel Reset.

LED Lamp and Mains Power Loss

Under normal circumstances the LED Lamp can be switched on for a self-timed period of 10 minutes, or
switched on permanently by means of the [Lamp] button. In the event of a 230VAC power-cut the LED
Lamp is automatically activated and self-timed for 60 minutes. The Lamp can be manually re-triggered for a
further 60 minute period by pressing the [Lamp] pushbutton. Note that in the interest of conserving battery
power it is not possible to switch the LED Lamp on permanently during a power-cut. Also, the blue backlight
is automatically disabled to conserve battery power.



Maintenance

Once installed the Noby-220iiiiR2 should provide many years reliable service. Routine testing and periodic
system maintenance should be undertaken by a competent person and in accordance with local statutory
regulations. With the exception of fuse replacement there are no user-serviceable parts inside the
enclosure. Although the standby battery is monitored for presence and capacity, it is nevertheless
recommended as a preventative measure to replace the battery at 4 year intervals.

In the event of a suspected fault with the control panel it is advised to disconnect the external loop wiring
and fit EOL resistors/capacitors directly at the control panel screw terminals. In this way it becomes possible
to determine whether the control panel itself or some other external factor is causing the fault.

The Noby-220iiiiR2 should be cleaned with a damp cloth. Avoid the use of detergents and solvents because
these could react with the inks and plastic parts of the facia. Ensure that water does not enter the enclosure.
