Functioning
The receiver is switched on after a current pulse caused by pressing any momentary (bell) button connected to the relay. After the next pulse, the receiver will be switched off. The relay does not have a “memory” of the contact position, which means in the event of a power failure and its subsequent return, the relay contact will be set to “off”. This prevents the controlled receivers from being switched on automatically without supervision after a prolonged power failure.
Attention!
BIS-411 1R1Z can’t work with backlit buttons.
The maximum total backlight current of all connected buttons must not exceed 5 mA.
Power table
The above data are indicative and will depend to a large extent on the design of a specific receiver (especially for LED bulbs, energy saving lamps, electronic transformers and pulse power supplies), switching frequency and working conditions.
Tips
Illuminated buttons
If too many illuminated buttons are connected, the lighting may switch on spontaneously or switch on permanently Maximum load current The contact current given in the technical data is the maximum value and may be subject to restrictions – more information. If the information provided indicates that the relay in the device is insufficient, it is recommended to use an external switching element (e.g. contactor) adapted to switch large surge currents. State memory The relay does not have a “memory” of the contact position. This means that after the power supply is switched on, the relay contact will always remain in the off state.
