Fermax DUOX PLUS Basic Relay for F1/F2 Function Activation

Fermax F-3233 DUOX PLUS Basic Relay for Additional Functions

The Fermax F-3233 is a basic relay module for the DUOX PLUS two-wire door entry system, designed for common auxiliary functions such as secondary door opening, courtesy light activation or gate control. It connects at any point on the DUOX PLUS bus without additional wiring and can be activated by the F1 or F2 buttons on DUOX PLUS monitors and telephones, by door opening commands, or by calls from panels or guard units.

Configuration is straightforward using jumper JP1 to set the relay as a Block relay (activated only by devices within the assigned block) or a General Entrance relay (activated by all users in the installation). The activation trigger and relay timing (1-99 seconds) are also configurable. Factory defaults are set for the most common installation scenario — F1 activation with a 4-second relay time — so in many cases no programming is required.
