1.8 ALARM CONTACTS INSTALLATION

The alarm inputs can be used to start recording or for recording rate adjustment. In addition, alarm
reactions such as camera display on the monitor, buzzer, e-mail and network alarm are available. The
alarm output relay can be switched if required. Alarm input response actions can be controlled according to
a flexible schedule.

1.9 RS-485 keyboard / PTZ Installation
All functions can be remote-controlled by the EKB-500 universal keyboard. Using the EEPbus protocol,
digital video recorders, keyboards and speed domes can be installed on one single RS-485 bus. One
system can comprise up to 8 keyboards.

1.9.1 General RS-485 bus installation

The EKB-500 keyboard uses a RS-485 simplex wiring; the signal is transferred via a single twisted pair line.
CAT5 network cable is recommended, UTP version (unshielded) is sufficient for normal applications. A
shielded cable should be used if the installed cables are expected to be highly susceptible to interference.
The number of devices installed in one bus is limited to 32, and the maximum cable length is 3,900 feet.
Both of these can be expanded using a signal distributor EverFocus Model EDA997A (see below).
