All alarms that need to be connected in the
house should be put into ‘Learn Mode’ by sliding
the switch on the back of the alarm to the ‘Learn
Mode’ position.
NORMAL MODE
LEARN MODE
The red LED will light up to indicate that ‘Learn
Mode’ has been selected.
Please note that when the alarms are placed
in ‘Learn Mode’ they can’t be inserted into the
mounting base.
Do not take out the battery during ‘Learn Mode’ as
this will interrupt the learn process.
Press and hold the test button at one alarm only,
until it beeps and the LED ashes. This alarm will
become the master and will start sending out a
specic house code to the other alarms.
As the other alarms receive the specic house
code, they will also ash the LED light.
When all alarms flash the red LED, they are
connected and can be switched out of ‘Learn
Mode’ and installed.

6. TEST FUNCTION:
After installation, and at least once per quarter,
test all of your alarms to ensure they are operating
correctly and are within range of each other.
It is recommended to check visually every week if
the LED ashes correctly (every 48sec.)
Press the test button on any alarm for 2 sweeps of
alarm signal 1 (--- --- ---) - Please refer to section
8. This will send out a test signal from the alarm; all
other connected alarms should receive the signal
within a short time. The alarms will emit a short
beep and the LED will ash every 8 seconds for
2 minutes.
NOTE: Test function also allows to send a depleted
RF signal to ensure an optimal operation in normal
conditions.
When the test signal is sent out, the alarms will
respond in two ways:
Smoke alarm signal: --- --- ---
Heat alarm signal: --- --- ---
Flood alarm signal: - - -
CO alarm low level signal: - - -
CO alarm high level signal: --- --- ---
Please note that only the originating alarm’s LED
will ash, so it can be identied.
9. PAUSE/HUSH FUNCTION:
If the heat alarms are to set into a false alarm
by cooking, replace, etc. they can be paused
for 10 minutes by pressing the test button on
the originating heat alarm only (indicated by the
ashing LED).
The reason of this is that it is necessary to locate
the source of the alarm before using the hush
function. This is to make sure that it is not a life
threatening situation.

To replace the battery, detach the heat alarm from
the mounting base by twisting counterclockwise.
Replace the battery respecting the polarities.
Attach the alarm in the mounting base by twisting
clockwise until it clicks, and test the alarm.
13. TROUBLE SHOOTING:
If you are experiencing false alarms with just general
cooking, you may have your heat alarm too close
to the cooking hobs and stove. Try reinstalling
slightly further away to alleviate any issues.
If the heat alarm does not work when the test button
is pushed, the probable cause is a faulty battery.
Check if the battery is worn out and replace it.
Always test the alarm after replacement of
battery.

7. NORMAL MODE:
In normal mode the LED will ash every 48 seconds
to show correct operation.
8. ALARM MODE:
When a rapid and constant change of temperature is detected, the heat alarm will go into ‘Alarm
Mode’. It will sound the alarm signal and the LED
will ash.
The heat alarm will also transmit the alarm signal
to the other connected alarms, which will also
sound the alarm signal after a short delay.
The CAVIUS Wireless Family have two different
alarm signals:
Alarm signal 1 (--- --- ---) is life threatening
alarms, like a smoke alarm.
Alarm signal 2 (- - -) is a non life threatening
alarm, like a ooding alarm:
FLOOD ALARM
SMART REMOTE
All CAVIUS interconnected alarms within the
can be added to the system as
they run on the same frequency and use the same
data protocol.This means that the wireless system
can consist of a combination of smoke, heat, ood
etc.
Place all alarms into ‘Learn Mode’ and repeat
section 1.
Always test connection to all devices by repeating
test function section 6 after adding devices.
11. LOW BATTERY SIGNAL:
Your product has a 5Y battery life.
When the battery is starting its end of life, a short
beep will sound out every 48 seconds for 30 days.
The alarm effected by the low battery will only
beep, no other connected alarms will sound.
It is safe to change batteries in the alarms without
going through the learn process again – they will
not forget the codes during the battery change
process.
