VISIT TRANSMITTERS
Visit CO alarm – electrochemical
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: 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 smoke alarm signal to be transmitted to all Visit receivers within radio range, you can activate broadcast
mode. This will override the radio key settings.
To activate broadcast, remove the CO alarm from the bracket to access the radio button, see Buttons and controls. Press the

radio button three times in quick succession. The radio LED blinks three times in blue to show that broadcast is activated.
Silencing (Hush)
 When the alarm sounds, after sensing CO, pressing the test/hush button will immediately stop the horn (the red LED
will continue to blink). If CO is still present, the horn will turn on again after about 4 minutes. The CO alarm can only be
silenced once during a CO incident. At levels > 150ppm CO the unit cannot be silenced.
Test and maintenance
Test the CO alarm and radio connection regularly, at least once per month. Always test it immediately after any holidays or
other extended periods of absence. Clean the outside case with a clean damp cloth. Avoid spraying air fresheners, hair spray,
paint or other aerosols near the CO alarm. Do not place air fresheners near the CO alarm. Do not paint over the CO alarm.

Changing the radio key
If your Visit system is activated for no reason, there is probably a nearby system that triggers yours. In order to avoid radio
interference, you need to change the radio key on all units. The procedure differs depending on your system setup.
Systems with different types of transmitters
Start by changing the radio key on all other transmitters in the system by moving any of the radio key switches, see the
corresponding user manual. Note: All transmitters must be set to the same radio key to operate as a group.
Step 1: Change the radio key on the BE1555 CO alarm
1 Remove the alarm from the bracket to access the radio button, see Buttons and controls. Press and hold the radio button
until the radio LED blinks slowly in blue. Release the button.
2 Press the test button on any other transmitter within 30 s to transmit the new radio key.
3
The radio LED on the alarm lights up in blue to show that the radio key has been changed.

Systems with only BE1555 CO alarms
Step 1: Change the radio key on the BE1555 CO alarms
Select one of the BE1555 CO alarms that will function as the master unit. The other alarms will function as slave units.
Remove the CO alarms from the brackets to access the radio button.
1 Press and hold the radio button on the master unit until the radio LED blinks slowly in blue. Press and hold the button
again to generate a new radio key. The radio LED will pulsate to confirm.
2
Press and hold the radio button on the slave unit until the radio LED blinks slowly in blue.
3 Press the test/hush button on the master unit and release it when the alarm sounds to transmit the new radio key.
4 The radio LED on the slave unit lights up in blue to show that the radio key has been changed. Repeat steps 2 - 4 to
change the radio key on an additional BE1555 CO alarm.
Steg 2: Change the radio key on the Visit receiver
1 Press and hold the test button on the receiver until the green and yellow Visit LEDs blink alternately. Release the button.
2
Within 30 s, press the test/hush button and release it when the alarm sounds to transmit the new radio key.
3 All Visit LEDs on the receiver blink 5 times to show that the radio key has been changed.
