The Flood Alarm is designed to detect a leak of 

water from washing machines, water pipes or un-

der-sink cabinets. It can also be used to detect 

flooded basements.
SAFETY INSTRUCTIONS:

The device comes with a 3V lithium battery. Batter-

ies are to be handled with care and battery pow-

ered devices should be kept out of reach of chil-

dren. Do not try to recharge or burn the batteries.
TECHNICAL INFORMATION:

linked within a house group is 32. 
Please note: These must be alarms from the CAV-

IUS Wireless Alarm Family.
The distance between interlinked alarms depends 

on the house layout and they should always be 

tested after installation. It is not advised to get 

more than 10m distance between two alarms.

1. HOW TO SET UP AND CONNECT ALARMS:
Open the flood alarm top cover by twisting counter 

clockwise. Remove the Test button / Lid to access 

the battery and the RF learn slide switch.

Start by pulling out the battery isolation strip as 

shown. 

Please note: The product label must not be re-

moved as it contains important information regard-

ing the product.
All alarms that need to be connected in the house 

should be put into ‘Learn Mode’ by sliding the 

switch on the top of the alarm to the ‘Learn mode’ 

position.

The red LED will light up to indicate that ‘Learn 

Mode’ has been selected. 

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 flashes. This alarm will 

become the master and will start sending out a 

specific house code to the other alarms.

As  the  other  alarms  receive  the  specific  house 

code, they will also flash the LED light.

When  the red LED light flashes on all alarms, they 

are connected and MUST BE SWITCHED OUT OF 

‘LEARN MODE’ and installed. 

Label the original “Learn” alarm in order to easily 

add new CAVIUS Wireless Family alarms to the 

system.

Remount the Test button / Lid. Close the flood 

alarm top cover by twisting  clockwise.
2. THE BEST AREAS TO INSTALL THE 

FLOOD ALARM:

• Install a flood alarm where it is hard to discover 

possible leaks.

• Install next to washing machine, dishwasher, 

uder-sink cabinet or in the cellar.

• Install in basements.
Place the alarm where it is reachable in order to 

test the battery.
3. AREAS WHERE NOT TO INSTALL FLOOD 

ALARMS:

• On the ceiling.
• On the wall (unless using accessory wall 

mounting base, see section 5).

• In rooms where temperature goes outside 

0°C to 40°C.

Place the alarm where it is reachable in order to 

test the battery.
4. PLACEMENT:
The flood alarm is designed to be placed on the 

floor near to possible leaks.

NOTE: If you place the flood alarm in places where 

a potential water leak / flood can rise higher than 

2cm, there is a risk of your flood alarm beeing dam-

aged. In these places we recommend wall mount-

ing base with probe.
5. ACCESSORY WALL MOUNTING BASE WITH 

PROBE:

NOTE: The wall mounting base with probe is an 

accessory  option  for  the  flood  alarm.  It  must  be 

purchased separately.
For installation in basements with risk of flooding 

or areas with difficult accessibility.
