This section includes answers to the features and ranges of products available, the compatibility with other products and other technical details like read ranges, voltages, etc.

Q: Which types of cards are compatible with XPR readers?
A: XPR readers are compatible with EM4002 cards.

Q: What is the operating voltage of XPR reader?
A: All readers operate at 12V DC, but Mini is available with two range of products, one operates at 5V DC and another operates at 12V DC.

Q: Can I use Mini reader with any other controller?
A: Yes, All the XPR readers are multi protocol and can be made compatible with most controllers. You can select a protocol among Wiegand26, Clock & Data and Codix.

Q: Can I install XPR controller outdoors?
A: Most of our products are IP65 and IP67 (International Protection ratings) and can be used outdoors in dusty and humid conditions.

Q: Do you have keypads with integrated proximity reader?
A: Yes, the DUO is a keypad with proximity reader and memory that supports 600 users. You can assign a double code or code + card for a User.

Q: How many doors can be controlled with O2LA system?
A: O2LA is 2 door access control system, but with extension unit EW control can be extended up to 64 doors. Each extension unit connects two doors and total of 31 EW's can be networked with O2LA. If you are using two readers for one door (Anti Pass Back mode) maximum of up to 32 doors can be controlled.

Q: Can the O2LA be synchronized with a Computer?
A: Yes,  PRO is access management software for O2LA system which allows synchronization with an compatible PC and provides the features like programming, online monitoring and report generation.

Q: Can I integrate Alarms with O2LA system?
A: Yes, O2LA provides two outputs for connecting alarms.

Q: Can I integrate a smoke detector / PIR sensor with O2LA?
A: Yes, O2LA provides one independent input connection facility to integrate other related security products like smoke detector/PIR sensor and provides a corresponding output to which you can connect an appropriate output device.

Q: What is CODIX?
A: CODIX is the proprietary protocol used in XPR products for communication between networked products.

Q: What is special about CODIX?
A: Communication over CODIX is bi-directional and uses only 3 wires – an advantage when distances are long.

Q: Where is CODIX used?
A: CODIX is used in XPR standalone controllers, when they need to be networked with slave readers. This feature increases security manifold as the controller is placed in a secure area and the slave reader becomes the user interface. Tampering with the slave unit involves no loss of security.

Q: What are “standalone” controllers?
A: Standalone controllers are products into which data can be entered, and which process the data and issues commands to open doors. In XPR range, standalone controllers can control from 1 to 4 doors independently. XPR has widened the ambit of “standalone” by introducing the CODIX bus, which enable slave units to be networked with the controllers, thereby greatly increasing flexibility and enhancing security.

Q: What is a slave unit?
A: A Slave unit does not have in-built intelligence. It merely reads a card, keyfob or a number entered on a keypad, decodes it, and passes the information to the controller. The controller makes the decision regarding grant or denial of access. It is not possible to control a door with only a slave unit – there must be a controller that stores information and makes decisions.

Q: What is the maximum distance between controller and slave unit?
A: Typically, the maximum distance is 100m. If slave readers are connected in parallel, the maximum distance will reduce.

Q: What does Mix-n-Match mean?
A: XPR products are unique in that they are designed with interior design in mind. As décor is never the same in two locations, XPR offers a wide variety of housing options. Options include metal, plastic and a range of colours. As electronics and housings are made to fit one another, it is possible to select the electronics according to security considerations and housings according to decoration considerations and mix-n-match the two.

Q: Can Proximity readers be fixed on metal surfaces?
A: In principle, they can be but reading distance will reduce. It is recommended that if a reader is to be fixed on a metal surface, the reader is isolated from the metal by an insulating plate – plastic or wood.

Q: How close together can readers be fixed?
A: The recommended minimum distance between two readers is 50 cm. This distance applies even to two readers fixed on either side of a door or wall. It applies to readers from two separate networks.

Q: Can a proximity reader read through glass?
A: Readers can certainly read through glass, wood or plastic commonly used for making doors and partitions. However, the total reading distance is unchanged. This means that if the total reading distance is 10 cm, a 4 cm wooden partition would leave an effective reading distance of 6 cm. The presence of metal hardware – locks, latches, screws, etc. can affect reading distance.

Q: What precautions should be taken when installing proximity readers?
A: Readers should not be installed close to sources of strong magnetic, electrical or electro-magnetic disturbances. Motors, power cables, computer monitors, TV receivers, RF devices, etc can adversely affect readers. Care should be taken to install readers and to lay cables away from such disturbances.

Q: What are the differences between MULTIX, ENTRIX and VISION ranges?
A: ENTRIX are a range of standalone controllers that work with the CODIX bus. VISION range comprise controllers that work with the international standard Wiegand 26 protocol. MULTIX are slave readers (proximity and keypad) that are truly multi-protocol, in that the protocol can be selected by the installer to suit the controller being used, even non-XPR ones.

Q: How is access to be gained with the VI200 when it has no keypad?
A: The VI200 is a pure controller. For inputting data, the VI200 has to be connected to keypads or proximity readers (MULTIX range) using the CODIX bus. The KPR9 is also a pure controller, with less features than the VI200.

Q: Can readers of other manufacturers be connected to XPR controllers?
A: Since the CODIX is proprietary to XPR, only XPR readers will work with CODIX. However, other readers can be used with XPR’s VISION range products provided they conform to the Wiegand 26 protocol.
