Both
entry
systems
only
offer
one
single
Doorstrike
control
port
for
one
entrance
door
or
gate.
The
Doorstrike
port
presents
a
relay
contact
closure,
which
together
with
a
power
transformer
makes
up
the
circuit
that
is
needed
to
energize
the
electric
Doorstrike
located
at
the
jamb
of
the
door.
For
a
door
entry
system
with
more
than
one
Doorstrike
control
port
(multiple
doors
and/or
gates
to
open), you will need
to
add
the
QX-3
module
to
your
package. This small module attaches to the Intercom Unit and delivers
4
individual strike ports (in addition to paging/music
interfacing),
distinctive
door
chime
with
your
door
chime
box
and
more. The
single-pair wires
from
each of your doorstrike devices need only be hooked up direct to
the
dedicated
strike ports on the
module,
no
separate
power
transformer
needed.
