Usage Features
- Mounting: The module is designed for standard DIN rail mounting. It can be mounted in dedicated DIN cabinets or on generic DIN rail mounting strip. Proper clearance around all sides of the device is required for adequate air flow. The module should be installed in an electrical room, communication equipment room, secure cabinet, or an accessible area of the ceiling.
- Position the DIN rail module with the labeling in the correct orientation.
- Hook the mounting tabs (opposite the tab clip) under the edge of the DIN rail.
- Push the DIN rail module against the mount until the tab clips over the rail.
- Removal:
- Insert a flat blade screwdriver into the hole in the module tab clip.
- Lever the tab outwards and rotate the unit off the DIN rail mount.
- Grounding: Proper grounding is essential for safety and to prevent damage from elevated voltages. The module requires a single-point earth ground connection. A minimum 14AWG solid copper wire (or thicker, in accordance with local authorities) should 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. 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.
- DC Power & Encrypted Module Network: The expander uses encrypted RS-485 communications. Both module and network power are supplied by the N+ and N- terminals. The 12V N+ and N- communication input must be supplied from only one point. Connections from more than one 12V supply may cause failure or damage. A 330 ohm EOL (End of Line) resistor must be inserted between the NA and NB terminals of the first and last modules on the RS-485 network.
- Door Access Control: The reader expander provides access control functionality without the requirement for additional hardware. It supports Belden 9842 or equivalent, and 24 AWG twisted pair with characteristic impedance of 120ohm for RS-485. For Wiegand, it supports 22 AWG alpha 5196, 5198, 18 AWG alpha 5386, 5388.
- Wiring Precautions: The card reader must be connected to the module port using a shielded cable. The shield must only be connected at one end of the cable in the metallic enclosure (frame grounded). Do not connect the cable shield to an AUX+, 0V or V- connection on the module. Do not connect the cable shield to any shielded for isolated communication. The reader and cable shield wires must be joined at the reader pigtail splice. Do not join the shield and black wires at the reading device. Do not terminate the reader shield wire inside the reader.
- Reader and Cable Shield Wires: These must be joined at the reader pigtail splice for all MIFARE capable ICT card readers. Older readers which are internally grounded and third-party readers do not require the shield wires to be joined.
- RS-485 Reader Locations:
- Entry: Green and orange wires not connected.
- Exit: Green and orange wires connected together.
- Wiegand Reader Connection: The module supports standard Wiegand reader connection with single LED and dual LED operation. Dual LED operation allows the signaling of both LEDs independently using the LED control lines, and is ideal to show the status of alarm or other integrated signals. Readers must also be programmed to operate in dual LED mode.
- Multiple Wiegand Reader Connection: In multiple reader mode, the secondary reader has all connections wired to the same port as the primary card reader, with the DATA 1 connection wired to the opposite reader connection DATA 1 input. The reader that is multiplexed into the alternate reader port will operate as the exit reader, and the normal reader connection operates as the entry reader.
- Magnetic Reader Connection: The reader expander allows the connection of standard magnetic track 2 format cards and provision is made in the software for a large number of formats. Formats include BIN number for ATM access control and first 4, 5 and 6 card numbers. Magnetic card readers are typically operated by 5 volts. Before connecting the magnetic card reader to the reader expander, ensure that the supply voltage is correct and if required insert the inline 5 volt regulator.
- Door Contact Connection: The module allows the connection of up to 4 contacts for monitoring and controlling access control doors. Each input can be used for either the door function that is automatically assigned or as a normal input on the system. The following example shows the connection of a normally closed door position monitoring contact to monitor the open, closed, forced and alarm conditions of the door.
- Door Lock Connection: The reader expander provides two lock output relays that can be used to switch electric locks. When using a door with an entry and exit reader on separate reader ports, the lock output should be connected to LOCK 1, and enable the Swap Lock LED Display option for the second reader input to allow the reader LEDs to display the correct status. The 1N4007 diode shown in the diagram is supplied with the reader expander and must be installed at the electric strike terminals.
- Inputs: The reader expander can monitor the state of up to 8 inputs. These inputs can be connected to a variety of EOL monitored dry contact devices such as magnetic switches and PIR motion detectors. Devices connected to the inputs can be installed to a maximum distance of 300m (1000ft) from the module when using 22 AWG wire. Each input may be individually configured for normally opened and normally closed configurations with or without EOL resistors for tamper and short condition monitoring.
- Magnetic contacts shall be listed to UL 634 to comply with UL installation standards and ULC/ORD-C634 to comply with ULC installation standards.
- Motion detectors and temperature sensors shall be listed to UL 639 to comply with UL installation standards and ULC-S306 to comply with ULC installation standards.
- The reader expander has been evaluated for UL 294 and CAN/ULC-S319 standalone access control.
- When using an input with the EOL resistor configuration, the controller generates an alarm condition when the state of an input changes between open and closed and generates a tamper alarm condition when a wire fault (short circuit) or a cut wire (tampered) in the line occurs.
- When using the EOL resistor configuration, the EOL resistor option must be enabled in the input programming so that the tamper and short states can be monitored.
- Trouble Inputs: Each reader expander can monitor up to 16 trouble inputs used to report trouble conditions such as module communications problems. Trouble inputs are used to monitor the module status and in most cases are not physically connected to an external input.
- Door Trouble Inputs: In addition to the trouble inputs of the module itself, the reader expander can also monitor trouble inputs associated with connected doors. These are used for monitoring and reporting door troubles such as door forced and duress conditions.
- Outputs: The reader expander has 8 programmable outputs. These outputs are used to activate bell sirens, lighting circuits, door locks, relay accessory products and other automation points.
- Lock Outputs (1 and 2): Relays are provided on outputs 1 and 2. These are used for the Lock 1 (Output 1 RD001:01) and Lock 2 (Output 2 RD001:02) functions and are used to control electric door strikes and other lock control devices. The relay outputs can switch to a maximum capacity of 7A. Exceeding this amount will damage the output.
- Standard Outputs (3 To 8): Outputs 3, 4, 5, 6, 7 and 8 on the reader expander are open collector outputs and switch to a ground connection. These outputs have a default pre-programmed function as detailed in the table and are used to control the indicator and audible outputs on the attached reading device. These functions may be disabled by programming the appropriate setting in the reader expander configuration.
- Beeper Outputs (5 and 8): The beeper outputs 5 and 8 on the reader expander provide diagnostic information to the end user and installer when a card is presented and access is denied or the unit is operating offline.
- Address Configuration: The module address is configured via programming and will require knowledge of the module serial number. The serial number can be found on the identification sticker on the product. Refer to the Protege system controller installation manual for address programming details. The controller has a set limit on the number of modules of each type that it can support. When adding and configuring modules always refer to the Maximum Module Addresses table in the controller installation manual.
