Wired Doorbell Chimes
Wired Doorbells can be powered by batteries only, transformer only or either battery or transformer depending on the model. Transformers connect to the mains power supply and drop the voltage from 240v to 8, 12 or 24Volts a/c for safe operation. They all must be connected to a wired bell push button which can be illuminated for transformer operation, but cannot be illuminated for battery operation.
All wired units can be extended with wireless units if a Wired to Wireless extender/ convertor is connected into the wiring from the bell push button. All transformer powered models must operate between 8v - 12v ac and be supplied with 1 amp transformer. If 2 bells are operated on the same doorbell wiring system then the total current supplied will need to be 2 amp transformer. It is important that bell wire or equivalent is used that can handle 1 amp (do not use Cat 5 or telephone cable) - we supply 9m lengths (code 7200) on our website.
