One or two door capable direct wired door chime works with either a doorbell transformer or batteries.

If you need a direct wired doorbell but don’t have a transformer, use this wired door chime with 4 x C batteries to power this chime.  (Also works with a transformer)

Please note, if you have a lighted push button, do not use batteries, use a transformer as the light will drain the battery.

• One or two door operation with different tones to distinguish which push button originates the tone
• AC operation for battery use, 4 x C sized alkaline batteries
• DC mode uses a 16 V transformer
