PRT-PSU-DIN-8A | Protege DIN Rail 8A Intelligent Power Supply | Installation Manual 4

Introduction
The Protege DIN Rail 8A Intelligent Power Supply provides 12VDC power suited to powering security, access
control or automation devices along with large numbers of Protege network powered modules, and allows for
simple and powerful monitoring of supply currents and voltages.
Flexible module network architecture allows large numbers of modules to be connected to the RS-485 module
network. Up to 250 modules can be connected to the Protege system in any combination to the network, over a
distance of up to 900M (3000ft). Further span can be achieved with the use of a network repeater module.
Locking a network prevents the removal, substitution or addition of modules to the module network effectively
preventing any tampering with the system.
The current features of the Power Supply include:
⦁Industry standard DIN Rail mounting
⦁Online and remote upgradeable firmware
⦁Secure encrypted RS-485 module communications

Installation Requirements
This equipment is to be installed in accordance with:
⦁The product installation instructions
⦁AS/NZS 2201.1 Intruder alarm systems
⦁The Local Authority Having Jurisdiction (AHJ)
PRT-PSU-DIN-8A | Protege DIN Rail 8A Intelligent Power Supply | Installation Manual 6

Grounding Requirements
An effectively grounded product is one that is intentionally connected to earth ground through a ground
connection or connections of sufficiently low impedance and having sufficient current-carrying capacity to
prevent elevated voltages which may result in undue hazard to connected equipment or to persons.
Grounding of the Protege system is done for three basic reasons:
1. Safety
2. Component protection
3. Noise reduction
Safety Grounding
The object of safety grounding is to ensure that all metalwork is at the same ground (or earth) potential.
Impedance between the Protege system and the building scheme ground must conform to the requirements of
national and local industrial safety regulations or electrical codes. These will vary based on country, type of
distribution system, and other factors. The integrity of all ground connections should be checked periodically.
General safety dictates that all metal parts are connected to earth with separate copper wire or wires of the
appropriate gauge.
Earth Ground Connection
The DIN Rail enclosure and the DIN Rail modules must be grounded to a suitable single-point earth ground
connection in the installation. A minimum 14AWG solid copper wire (or thicker, in accordance to local
authorities) shall be used from the Protege system's earth connection points.
The DIN Rail enclosure includes an earth ground single-point link connection via the metallic enclosure. This
single-point link is the Protege system's earth ground. All modules that have earth ground connections and that
are installed in the same enclosure shall be connected to this single point. A single-point earth ground
connection avoids the creation of ground loops in the system and provides a single reference point to earth
ground.

Mounting
Protege DIN Rail modules are designed to mount on standard DIN Rail either in dedicated DIN cabinets or on
generic DIN Rail mounting strip.
When installing a DIN Rail module, ensure that there is adequate clearance around all sides of the device and
that air flow to the vents of the unit is not restricted. It is recommended that you install the module in a location
that will facilitate easy access for wiring. It is also recommended that the module is installed in an electrical
room, communication equipment room, closet or in an accessible area of the ceiling.
1. Position the DIN Rail module in the correct orientation, with the writing on the face the right way up.
2. Hook the mounting tabs (opposite the tab clip) under the edge of the DIN rail.
3. Push the DIN Rail module against the mount until the tab clips over the rail.
Removal
A Protege DIN Rail module can be removed from the DIN Rail mount using the following steps:
1. Insert a flat blade screwdriver into the hole in the module tab clip.
2. Lever the tab outwards and rotate the unit off the DIN Rail mount.
Cabinet Tamper Switch
The enclosure tamper input notifies the monitoring station or remote computer that the enclosure has been
opened. The tamper input switch and steel bracket provided should be correctly mounted into the enclosure
and secured to the wall. The tamper input switch terminals are connected in series with the tamper input (TP)
and the V- terminal of the Power Supply (or any other system input designated and programmed as a 24HR
tamper alarm input). When the tamper input is triggered, Trouble Input AExxx:01 on the Power Supply will be
opened.

Modes of Operation
When using the sensor in momentary mode, it will be necessary to connect using a 4 core cable.
⦁The N.C. alarm contacts are non-latching.
⦁Upon alarm activation the alarm contacts will open circuit momentarily for a minimum time of 1 second
before automatically resetting.
⦁The LED will illuminate when the alarm contacts are open circuit in response to an input signal.
⦁LED Indication: During the sensitivity test procedure, indication of the green LED denotes alarm and relay
operation. Indication of the red LED denotes vibration detected (pulse) but insufficient to create alarm
conditions.
⦁Dual stage linear sensitivity: The detector permits the installer a greater threshold of sensitivity adjustment
by adjustment of the potentiometer through either a low level or high level adjustment.
⦁When DIP Switch 5 is in the On position the sensitivity potentiometer allows adjustment in the high
sensitivity area and when in the Off position allows adjustment in the low sensitivity area.
Installation Procedure
1. Select the intended position for installation, ideally positioned horizontally in the vertical center of the
enclosure, 50mm to the right of the large opening, ensuring the surface is clean and clear of any
irregularities.
2. Remove the sensor cover by unscrewing the single captive screw until the cover can easily be removed
from the base.
3. Carefully lift the printed circuit board from the base.
4. Position the base in the mounting position and mark the desired fixing holes (3.1mm drill).
5. If rear cable entry is required, cables should be threaded through the rear of the base.
6. Fix the base in position using M3 pan head machine screws to the captive nuts provided in the enclosure, or
with nuts and washers if located in an alternative position. Take care not to let the screw protrude further
than the nut height on the rear of the enclosure.
7. Carefully push the printed circuit board onto the base.
8. Make the electrical connections to the Shockgard SS-102, wired in series with the enclosure tamper switch
24Hr monitor.
9. If side cable entry is being used, remove the appropriate knockout from the cover and insert a grommet.
10. Setting up and adjustment: With the unit in momentary operation (See Modes of Operation: Dual stage
linear sensitivity above), use a terminal screwdriver to turn the sensitivity control fully clockwise to

Warning:
⦁Only attach standard lead acid batteries.
⦁Do not connect the battery wires or B+ and B- plugs of the Power Supply to any other ancillary device
(siren, lock or mag clamp etc).
⦁An incorrect connection may cause erroneous faults or serious damage to the Power Supply and will
VOID ALL WARRANTIES OR GUARANTEES.
The battery test procedure uses a special algorithm to prevent deep discharge and increase battery
endurance. A dynamic battery test is performed every ten minutes when mains power is present and a battery
condition alarm will be generated if the battery is either disconnected or shows poor capacity. Battery fault
conditions will activate the battery trouble input associated with the address assigned to the Power Supply.
In addition to the dynamic battery test procedure, the Power Supply performs a battery presence test every
60 seconds, which determines whether the presence of a backup battery is detected. Similarly, a battery
condition alarm will be generated and the battery trouble input associated with the address assigned to the
Power Supply will also be activated.
To comply with EN 50131-1 only one battery can be connected and monitored per system. If more capacity is
required a single larger battery must be used.
PRT-PSU-DIN-8A | Protege DIN Rail 8A Intelligent Power Supply | Installation Manual 14

Encrypted Module Network
The Power Supply incorporates encrypted RS-485 communications technology. Network power is supplied by
the N+ and N- terminals. Connection of the communications and network power should be performed according
to the diagram shown. It is important that the N+ network communications power be 12VDC supplied from an
independent battery backed power supply unit or a networked module capable of supplying the required
voltage to all devices on the RS-485 network.

Output Load Connection
The Power Supply provides two sets of 12VDC output terminals, V1+ and V2+.
Both V1+ and V2+ outputs are individually fused, with 6 terminals associated to each output and its individual
fuse.
A maximum current output of 6.0 Amps at 12VDC can be provided across each output at any one time.
However, if a single current output of 8.0 Amps is required, then both outputs need to be connected together in
parallel.
When any inductive load including electric locking devices is powered (directly or indirectly) by the Power
Supply, a reverse EMF protection diode must be placed across the positive (V1+ or V2+) and negative (V-)
terminals at the device.

programming, trouble input and output information is stored in and reported by the Analog Expander records
when programming via a Protege Keypad or Protege software.
PRT-PSU-DIN-8A | Protege DIN Rail 8A Intelligent Power Supply | Installation Manual 19

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).
