Outputs
The Power Supply has two 50mA outputs that can operate as either programmable outputs or as predefined
status outputs, depending on the network status of the module on the Protege system.
Online Mode
Upon successfully completing the initial registration with any Protege System Controller, the outputs of the
Power Supply operate in
Online Mode
. The module will then continue to operate in Online Mode until a firmware
update is carried out. While in Online Mode the 2 outputs function as
programmable outputs
and can be used
to activate bell sirens, lighting circuits, door locks, relay accessory products and other automation points.
Programmable Outputs
The 2 programmable Outputs each have a 50mA Solid State relay.

Warning:
Switching inductive loads that can produce high back EMF voltages or large voltage induced spikes
can cause the module to behave unexpectedly and should be avoided. A suitable isolation circuit must be
installed between the relay contacts of the module and the inductive load.
These outputs are rated for low power use only (50mA, 12V Max). Incorrect use may cause erroneous faults
or serious damage to the Power Supply and will VOID ALL WARRANTIES OR GUARANTEES.
Offline Mode
Until connection to a Protege System Controller is established, the outputs of the Power Supply operate in
Offline Mode
. While in Offline Mode the 2 outputs function as status outputs. In addition to the comprehensive
front panel diagnostic indicators, these status outputs offer additional information that can aid the installer in
diagnosing faults and conditions.
AC Fail Status Output
The AC Fail Status Output has a Solid State relay. The output relay contacts disconnect (Normally Open) when
AC power is removed and the unit remains running on backup battery power. Upon restoring AC power, the
output relay will revert back to its default state (Normally Closed).
