Keypad Bus Monitor
For Fire Protective systems, the Model 893A Module must be installed in the XR100/
XR500 or XR150/XR350/XR550 Series control panels to monitor the keypad bus and
sound an audible trouble alert whenever the keypad bus fails to operate. Refer to the
893A Module Installation Sheet (LT-0135).
The
Model 277 Buzzer may be installed as an audible trouble alert in place of the
Model 893A Module for XR150/XR350/XR550 Series control panels. Refer to the 277
Buzzer Module Installation Sheet (LT-1296).
Card Readers
When a proximity credential is presented to an internal or external reader, a beep
tone is heard and the Power and Armed LEDs blink. This provides both an audible and
visual acknowledgement of the credential read.
Internal Access Control Reader
The 7563/7563A and 7573/7573A keypads provide a built-in proximity card reader
designed to read DMP/HID 1300 Series proximity credentials.
Note:
For listed access control applications, the keypad must be installed within the
protected area.
External Access Control Reader
To accept Wiegand data input from other external card readers, connect a 12 VDC
external reader to the 7573/7573A keypad. Connect the Red and Black power wires
from the reader to the power wires from the panel. These connect in parallel with
the keypad power wires. Connect the Reader (Data 1) wire to the White wire on the
5-wire keypad harness. Connect the Reader (Data 0) wire to the Green/White wire on
the 5-wire keypad harness. See Figure 2.
