Installation
Make sure to select a location complying with the advice in Location and positioning.
1 Remove the mounting bracket from the CO alarm by turning it counter-clockwise.
2 Taking care to avoid any electrical wiring, fix the mounting bracket to the ceiling or wall
using the supplied screws and plugs.
3 Fit the alarm to the bracket by turning it clockwise until is snaps into place. The red, yellow
and green LEDs blink in sequence to show that the unit is on.

Testing the connection
1 Wait 15 s. Press the test/hush button and
release it when the alarm sounds. The CO
alarm transmits a radio signal to the receiver.
2 The orange and red LEDs on the Visit receiver
blink alternately to show that the signal was
received. In addition, it starts to sound, flash or
vibrate depending on the receiver.
Note: The alarm will stop sounding after the
button is released and the Visit receiver will time
out in less than a minute.

Signal pattern
When the alarm detects over 43 ppm CO, the red LED blinks in accordance with the table. This
helps locate CO leaks as the alarm gives an indication straight away. This pre-alarm signal may
be triggered by CO coming from e.g. cooking with gas, car engines or nearby barbecues. This
is usually not a concern, unless the pre-alarm signal persists until the alarm sounds and the
CO source is unknown. Note that the alarm may sound if cigarette smoke is blown into it, or
aerosols are released nearby.
Depending on the cause of the alarm, the signal patterns are as follows:
CO level / fault
Alarm LED
> 43 ppm
1 red blink every 2 s
> 80 ppm
2 red blinks every 2 s
>150 ppm
4 red blinks every 2 s
Low battery
1 yellow blink / min
Faulty unit
2 yellow blinks / min
End of Life
3 yellow blinks / min
Note: When the low battery warning occurs for the first time, you have at least 30 days to replace the
unit. You can press the test/hush button to temporarily hush the low battery warning for 24 hours.
Using broadcast
If you want the alarm signal to be transmitted to all Visit receivers within radio range, you can
activate broadcast mode. This will override the radio key settings.
1 Remove the alarm from the bracket to access the radio button, see Overview.
2 Press the radio button three times in quick succession. The radio LED blinks three times in
blue to show that broadcast is activated.
