Introduction
The Protege Module Network Repeater is designed to extend the network capabilities of the Protege system, an
advanced technology security product providing seamless and powerful integration of access control, intruder
detection and building automation.
The network repeater is added to the system via RS-485 or ethernet and provides optical isolation between up to
three branches of the module network, easing power requirements.
The current features of the network repeater include:
⦁3 isolated RS-485 connections
⦁10/100 ethernet
⦁RS-485 or ethernet network expansion
⦁Secure encrypted RS-485 module communications

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 with 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, secure cabinet, or in an accessible area of the ceiling.
1. Position the DIN rail module with the labeling in the correct orientation.
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.

Power Requirements
Powering the Network Repeater
For devices using hardware revision 010, COM1 is only used for supplying power to the network repeater when
connected via ethernet.
Power to the network repeater is supplied by the N+ and N- terminals on the COM1 port and is also used for the
onboard electronics and the ethernet connection.
When the network repeater is connected to the module network via ethernet, module power is supplied to the
COM1 port via a 12VDC independent battery backed power supply unit capable of supplying the required voltage.
This same power supply can be used to supply the COM1 module network spur as well, as long as the maximum
load of the power supply is not exceeded.

on Network
If the network repeater is inserted into an existing section of the module network the auxiliary outputs of a
controller can be used to supply other equipment.
Note that there is no onboard regulation or isolation for these outputs; they are a fused feed-through from the N+
N- input terminals.
When using these outputs to supply other devices, be sure not to exceed the rating of the internal fuses as
outlined in the Technical Specifications (see page24).
