Who it fits
Good fit for
This chime suits homeowners replacing a broken mechanism in a traditional wired doorbell system. It works well if you want separate alerts for front and back doors. The compact size fits most standard wall spaces. You need an existing 16-volt transformer and a compatible cover to complete the look. It is ideal for those who prefer simple, reliable mechanical chimes over smart features.
Who should skip it
Skip this if you need a complete doorbell kit. This listing does not include the cover or the push-button. You must purchase those separately. It also lacks smart connectivity, so it will not send notifications to your phone. If your current transformer is not 16-volt, you will need to buy one separately. It is not suitable for wireless or battery-powered setups.
Verdict: The Newhouse Hardware CHIMEBASE2 is a practical, spec-driven replacement for standard wired doorbell mechanisms. It delivers two clear tones in a compact, compatible form factor.
Key specs for this chime
Melody Count: 2
This mechanism plays two distinct tones. You hear a classic two-note ding-dong for the front door. A separate dong sound triggers for a rear or side entry. This lets you identify which door is being used without looking at a screen. Smart doorbells often use app notifications instead. If you prefer audible cues, this dual-tone feature helps distinguish entries.
Receiver Power Source: 16-volt transformer
The chime requires a 16-volt transformer to operate. You must connect it to a compatible 16-volt/10 VA or 16-volt/15 VA unit. The transformer is not included. Standard wired doorbells use this voltage. Smart doorbells often need similar power but may have different requirements. Check your existing transformer before buying to ensure it matches these electrical specifications.
Size: 6.75” L x 4.75” W x 1.75” H
The base measures 6.75 inches long, 4.75 inches wide, and 1.75 inches deep. These dimensions allow it to fit most Nutone models. You should measure your old chime before purchasing. Replacement units must fit inside the existing housing. This physical size is critical for DIY swaps. It ensures the new mechanism sits securely without modifying the wall box or cover plate.
Trigger Type: Push button
This chime activates via a standard push-button doorbell. You press the button to trigger the sound. It works with traditional wired buttons. Smart doorbells also use push buttons but add video and audio features. This mechanism responds to the physical signal from the button. It does not include smart connectivity or app control on its own. It serves as the sound receiver for wired setups.
Build and physical layout
According to the listing, this unit is finished in black. The base itself measures 6.75 inches in length, 4.75 inches in width, and 1.75 inches in depth. These dimensions are critical if you are replacing an existing mechanism. You must measure your current chime before purchasing to ensure the new base fits inside the housing. The package includes the door chime base and mounting screws. It does not include the cover or the doorbell button. You will need to source a compatible cover separately if yours is missing or damaged. The brand notes it fits most Nutone models, including specific series like LA11, KA10, and L12. This broad compatibility suggests the internal mounting points align with standard industry designs. The black finish allows it to blend with dark trim or modern fixtures. Since the cover is sold separately, you can choose a style that matches your home’s exterior. The mechanism itself is designed to sit securely inside the chime box. The included screws provide a direct path for installation. You should verify the space inside your existing chime housing. The 1.75-inch depth is a standard profile for most residential doorbells. This design prioritizes function over form. The focus is on fitting into existing spaces rather than changing the external appearance. You handle the aesthetic choices through the cover selection. The base provides the core functionality. It connects to your doorbell transformer to power the two-tone sound. The physical layout is straightforward. It relies on standard mounting hardware. This makes it a practical choice for standard wired setups. You get a reliable mechanism that fits common frames. The black color is a neutral choice for most homes.
Setup and everyday use
Installation requires a 16-volt transformer, which is not included in the box. You must verify your existing transformer matches either 16-volt/10 VA or 16-volt/15 VA specifications. If your current unit does not meet these requirements, you will need to purchase a compatible transformer separately. The package includes the chime base and mounting screws, but it does not include a cover or the doorbell button itself. You can search for compatible covers separately if needed.
Before mounting, measure your old chime mechanism carefully. The base dimensions are 6.75 inches long, 4.75 inches wide, and 1.75 inches deep. This unit is designed to fit most Nutone models. If your existing hardware falls outside these dimensions or model compatibility, this replacement may not work for your setup.
Daily operation is straightforward. The mechanism responds to a standard push button trigger. When you press the front door button, you hear a classic two-note ding-dong sound. If you connect a separate button for a rear or side door, you can assign a distinct dong sound to that input. This allows you to identify which entrance is being used without looking at the camera or checking your phone. The system relies entirely on wired power, so consistent performance depends on a stable transformer connection. There are no battery replacements or wireless pairing steps involved in routine use.
Before You Buy This Chime
You need to verify several details before installing this unit. The listing states the box contains only the base and mounting screws. It does not include the cover or the doorbell button. You must source a compatible cover separately. Search for CHM3DCOVER to match this mechanism, or consider the CHM3D bundle if you need both parts. Physical dimensions are strict. Your existing housing must accommodate a base that is 6.75 inches long, 4.75 inches wide, and 1.75 inches deep. Measure your current space carefully. Electrical requirements are specific. You need a 16-volt transformer rated at either 10 VA or 15 VA. This device works with standard wired doorbells, not smart video doorbells directly. If you are building a full smart entry system, this chime serves as the audible component for your existing bell circuit. Ensure your transformer supports the load before connecting.
Check before you buy
- Measure your existing chime housing dimensions against 6.75 x 4.75 x 1.75 inches.
- Verify your transformer outputs 16 volts with 10 VA or 15 VA capacity.
- Confirm you need a separate cover since the base is sold alone.
- Check if your current doorbell button is compatible with the new mechanism.
- Ensure you are not connecting this directly to a smart video doorbell system.
