Connecting External Switches
Door/window sensors can be connected to either normally
open (close on alarm) or normally closed (open on alarm)
external switches. Wire multiple, normally closed switches
in series. Wire multiple, normally open switches in parallel.

Do not attempt to use the built-in reed switches and an
external switch on the same door/window sensor. For high
security installations, always remove both reed switches
when connecting an external switch to the sensor terminals.
