Changing the radio key
If your Visit receiver is activated for no apparent reason, there might be another Visit
system installed nearby that accidently triggers your system. To avoid the radio interfer-
ence you need to change the radio keys on all units in your system. Proceed as follows:
1 Move the desired radio key switches on the smoke alarm unit/s to the up=on
position, see Figure 8.
2 Pair all Visit receivers in your system to the smoke alarm unit (see the receiver user
manual for correct pairing procedure).
Please note
 All Visit products within the same
system must be set to the same
radio key in order to operate as a
group.
 By default, all Visit transmitters are
factory set to the same radio key,
channel 0 and all radio key switches
on the smoke alarms are set to the
O=Down position.
