UNIVERSAL EXPANDER
FOR CARD / CHIP READERS
INT-R
int-r_en 09/11
The INT-R expander interfaces with the INTEGRA and CA-64 alarm control panels, replacing
the previously offered CA-64 SR and CA-64 DR expanders. This manual applies to the
expander with electronics version 2.0 and firmware version 3.00 (or later).
1. Features
•
Support for two proximity card / DALLAS chip readers.
•
Support for WIEGAND 26 interface readers.
•
Capability to arm / disarm and clear alarm by using the readers.
•
Capability to implement access control function – control of a single door.
•
Relay to control the electromagnetic door lock.
•
Input for door status control.
•
Input for door unlocking with a button.
•
Capability to automatically unlock the door in case of fire alarm.
•
Additional NC type tamper input.
2. Installation and start-up
Disconnect power before making any electrical connections.
The expander is designed for indoor installation, in spaces with normal air humidity.
1. Secure the expander board in its enclosure.
2. Determine the expander operating mode (see: S
ELECTING THE EXPANDER
OPERATING
MODE
).
3. With the DIP-switches, set the appropriate expander address. To set an address, use the
switches 1-5. The address must be different from that in the other modules connected to
the expander bus. The address is the sum of numerical values set on the switches 1-5
(see Table 1).
Switch number
1 2 3 4 5
Numerical value
1 2 4 8 16
Table 1. Numerical values corresponding to the switches set to ON position (in the OFF
position, the value 0 is assigned to each switch)
4. Connect the CLK, DTA and COM terminals with wires to the appropriate terminals of the
control panel expander bus. To make a connection, it is recommended to use an
unscreened straight-through cable. When using the twisted-pair type of cable, the CLK
(clock) and DTA (data) signals must not be sent through one twisted pair. The wires must
be run in one cable. The cable length should not exceed 1000 m. If it exceeds 300
meters, it may be necessary to use several wires connected in parallel for each signal.
5. Connect readers to the respective terminals (see: C
ONNECTING THE READERS
).
6. Connect the door status control detector to the IN and COM terminals.
