Purpose
Electronic bistable pulse relay BIS-411B allows switching on or off
the lighting or other device from several different points by paral-
lel connected, momentary (bell) control switches.
A push button on the housing enables direct control of the cir-
cuit without the need to trigger external buttons.
Functioning
The receiver is switched on after a current pulse caused by pres-
sing 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. The button on the housing performs
exactly the same function as the external button connected to
the terminals of the device.
