2.2.4RS-485 interface

One Main Unit and up to 32 Relay Units can be connected by a RS-485 bus. The bus must be connected to pins 2 and 5 of the RS-485 socket.

For connector wiring, see Section A.5.3 RS-485 socket (unit rear), page 30.

NOTICE!

Keep polarity equal when connecting further units to the RS485 bus!

NOTICE!

Maximum RS485-bus length: 3’900 ft (1200 m).

Use only one twisted pair cable for the interconnection.

NOTICE!

The receiver units located at the two ends of the bus must be terminated with a 100 Ohm resistor. See Section 3.2.6 Connecting the RS-485, page 16 for more information about the jumper setting.

In this configuration, you always should connect the Main Unit first. The Relay Units must then be connected to the RS485-bus one by one, not at the same time.

Relay output

In the same connector, a potential free contact is available. It is a low current switching contact. The relay (potential free, switching power max. 48 V / 0.5 A) is activated at a call for help, call for assistance or fire alarm. This relay can be set as closing or switching contact (cycle of 10 seconds on / 10 seconds off). This feature can be used to drive a signal lamp for example.

For connector wiring, see Section A.5.3 RS-485 socket (unit rear), page 30.

For relay setting, see the user manual of the Main Unit.

2.2.5Antenna

The antenna is connected to the Relay Unit using the adapter supplied with the unit.

See Section 3.2.4 Installing the antenna, page 14.
