CA-64 DR
ca64dr_en 07/08
The CA-64 DR expander for DALLAS chip readers is a device designed to interact with the
CA-64 and INTEGRA alarm control panels. It supports the DALLAS chip readers which
transfer data in the Touch Memory (DALLAS) standard. The expander can work
simultaneously with two heads of this type. Its function is to control the access to and operate
the electromagnetic door lock (or to control the operation of another device requiring the
access control). This manual is drawn up for the expander with firmware version 1.06 or later.
Note:
Using of all available in the module functions is possible only in case of interact with
control panels of INTEGRA.
