Product Information

In most cases, where the product is found to have a valid fault, the warranty permits complete replacement of the defective item free of charge.

unit simply plugs into a power socket and the terminated ends can then be screwed in place to provide power to your video doorbell. When I stripped some insulation from the four cores, two momentarily touched each other and there was a visible spark, so there was power although I can't now reproduce this. With a robust 12W capacity, this power supply can handle the demands of your Aqara Smart Video Doorbell G4 and many other compatible devices. Our selection includes wireless, wired, plug-in and battery doorbells from trusted brands like Byron, Honeywell and Swann. The mass and the screw have differing impacts, so making this thing work "properly" involved adjusting both the mass and the screw to get "perfect" behavior.Neighbors located in the UK can use the DIN Rail Transformer as a suitable transformer for the Video Doorbell Wired, which requires 18mm or 36mm module space in a suitable DIN Rail enclosure. The upshot is that you've created a "mechanical switching" inverter supply and the output of the transformer will be a useful AC voltage. Unless they are sold as kits, a doorbell will need a bell push button and bell wire as well - the bell wire must be good quality to prevent "voltage drop" at these low voltages (a symptom is that the doorbell will sound feeble). Low Voltage Power Supply, AC to DC Adapter, Constant Voltage for LED Strip Lights and Cabinet Lights, LED Bulbs, Ring Doorbell. Wired door bells can therefore be preferred if a system that draws more power is required, which would quickly run down battery operated alternatives.

I found a fat AC doorbell lying in my garage taking dust, and I want to use it as an additional acoustic signal for my DIY home alarm.

If the transformer is not within this power requirements, then it will not be compatible with the Doorbell Wired. I can't check the voltage at the chime because it was boxed in behind plasterboard last year as I thought we didn't need it.When you add the transformer, uncover the relay, turn out the lights, and you may see small sparks fly across the moving contacts.
