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.
