Magnetic Door Hold Units
If magnetic door hold devices
are
required,
it
is
recommended that they are
connected as shown in the
upper right diagram. This is
suitable if it is convenient to
cable to the control panel.
An Input/Output module may
also
be
used
for
this
operation, in which case a
relay would not be required.
We recommend the use of
24V DC Magnetic Door Hold
units, in order to enable them
to operate from a power
supply with a battery standby.
This
ensures
normal
operation in the event of an
interruption to the power
supply.
For assistance in choosing a
suitable power supply unit,
standby
batteries,
and
Magnetic Door Hold units
please contact your supplier.
