CHANNEL SETTINGS
The AlertMaster AL11 uses radio signals to communicate between
the console unit and all of its accessories. For the accessories
(Doorbell, Door Announcer) to activate the base unit, they all
have to be on the same “channel.” A “DIP switch” is used for
channel selection.
Your system and all the accessories have been preset in the factory
to a standard channel setting. Under normal operating conditions,
no adjustment is necessary.
If your system encounters interference and repeatedly activates
itself for no obvious reason, it may be triggered by a system nearby
in your neighborhood.
If the interference from another AlertMaster Notification System
or other wireless source is present, change channel switch settings
on all components.
1. Unplug AC cord and locate DIP switches on the back of the
AL11 base unit. Lift rubber cover to access the switch.
2. Open the battery compartment of the doorbell to access DIP
switches.
3. Change the switch position of each switch on both units using a
ballpoint pen to slide the switches to different settings. All settings
need to be identical for the system to work.
4. Unplug and change the switch settings on each of your other
accessories (Remote Receiver, Door Announcer, etc.) to match
the new channel setting of the AL11 base unit and doorbell.
5. Replace covers and return accessories to their proper place.
