Artisan - 4950PMB 7 Day Bell Controller

Description

The model 4950PMB is an ideal bell controller for use in factories and schools. The 4950PMB permits programming the exact time that the bell is to ring. In addition, the 4950PMB permits programming the interval of the ring from 1 to 99 seconds. The external bell system can be programmed to sound up to 99 times per day. Once a daily pattern has been programmed, it will repeat every day of the week until reprogrammed. A major feature of the 4950PMB is the smart timepiece circuit that continues keeping correct time and day, even when the power fails for up to a week. This feature assures that the 4950PMB will not have to be reprogrammed after every power failure. The 4950PMB does not require any batteries to assure this feature.
