Functioning
The receiver is switched on after a current pulse caused by pressing any momentary (bell) button connected to the relay. The receiver is turned off after the next impulse or utomatically
after the set off time. A longer pressing of the momentary button (lasting at least 2 seconds) turns on the relay permanently. The relay will be turned off only after pressing the momentary button again (or after a power failure).
Note!
BIS-410 24 V is not compatible with backlit buttons.
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.
