Wired Doorbell Charger ENTAC EDB-AC-44 — AC plug-in receiver with wireless IP44 battery transmitter (CR2032), 220–240V, range up to 150 m, white

ENTAC EDB-AC-44 is a compact wired doorbell system composed of an AC plug-in receiver and a battery-powered wireless transmitter rated IP44. The receiver plugs into a 220–240 V mains socket and provides audible notification when the wireless transmitter is activated. The transmitter is powered by a single CR2032 coin cell and transmits to the receiver with a maximum line-of-sight range of up to 150 m. The housing is white and compact (70.8 × 70.8 × 39 mm), designed for residential and light commercial entry notification.

Advantages

The system combines mains-powered receiving unit reliability with a low-maintenance battery transmitter, providing continuous power at the receiver and minimal upkeep for the push-button device. Its IP44 rating gives protection against splashing water and solid objects over 1 mm, allowing safe outdoor placement of the transmitter under common weather conditions. The compact dimensions and neutral white finish enable discreet installation at entrances without occupying significant space.

Suitable for

• Homes and apartments where a plug-in receiver is required
• Small offices and shops for visitor notification
• Porch or sheltered outdoor entrances where IP44 protection is sufficient
• Locations requiring a wireless transmitter due to difficulty routing wiring

How to use

Plug the receiver into a standard 220–240 V mains outlet within range of the entrance where the transmitter will be installed. Insert a new CR2032 battery into the wireless transmitter following the polarity markings. Mount the transmitter at the desired entrance point, preferably under a small canopy or sheltered area to optimize protection while preserving the IP44 rating. Press the transmitter button to test pairing and sound output; consult the included manual for pairing steps or tone selection if multiple tones are available.

Usage recommendations

Place the receiver in an unobstructed mains outlet indoors to maximise signal reception. Replace the CR2032 battery annually or when the transmitter response weakens. Avoid direct exposure of the transmitter to heavy rain despite its IP44 rating; mount it under eaves or a small shelter for longer service life.
