BUS2 Relay (Ref.3247)
The BUS2 Relay makes potential free relays available in BUS2 systems, with various functional and activation modes
to be configured:
- relay activation using commands generated from the residential terminals and/or entry panels.
- external activation: using buttons, additional external switches, etc.
The BUS2 relay is installed in an intermediate point on the bus without the need for the additional wiring.
BUS INPUT: BUS2 Input Connector.

2 BUS OUTPUT: BUS2 Output Connector.

Potential FreeRelay Contacts (max 5A):
· C, NO, NC: Common, normally open, normally closed.
· +12: Auxiliary 12Vdc Voltage Output
· Led Relay ON: Active Relay Output Indicator Led
4 External Relay Control:
· ACT/EXT, GND: Relay Activation via External Contact. Activates the relay as a result of a short circuit
between ACT/EXT and GND terminals.
· ENAB/DISABLE, GND: Disable any action taken on the relay (as a result of an external command or
activation) during a short circuit between both terminals.
5 CONFIG: Configuration Dipswitches.
· DSW1 MODE: Configuration of Relay Operating Mode
· DSW2 COMMAND: Configuration of control mode (control commands, external activation)
See "BUS2 Relay Configuration" Section
6 PRG: Programming Button.
Led Relay ON: Relay Indicator Led in programming mode.
BUS2 addresses can be programmed on the BUS2 relay (from 1 to 1999) such that they will only respond to
activation commands from a device whose address corresponds to one of those programmed at an earlier position
on the relay.
See "BUS2 Relay Configuration" Section
7 Activation TIME Allows the relay's activation time be programmed (from 1 to 600 seconds) when it is configured
in the timed operating mode.
· SEC: Each press increases the activation time by 1 second.
· 10xSEC: Each press increases the activation time by 10 seconds.
See "BUS2 Relay Configuration" Section
8 TEST: Connector available to connect the "BUS2 Verifier", (see the BUS2 Verifier" section).
