Cisa Booster for Electric Locks

BOOSTER is an electronic circuit that allows the following functions to be added to the ElettriKa series locks: Voltage adaptor for voltages other than 12 Vac. BOOSTER guarantees proper operation also with voltages of 12 Vdc, 24 Vac, 24 Vdc. Reduced input for all those installations where there is a need to have loads with low current input (for example, interphones with a 250 mA input). Undersized power supply BOOSTER guarantees sufficient power supply to the lock. Electric hold open function by installing a switch parallel to the lock opening button, the lock can be kept in a continual operable state, i.e. 'Hold open' (only for ElettriKa).
