Door Chime ZAMEL Sundi GNT-921-CZN BIM-BAM 8V two-tone gong SUN10000484 black

Wired door chime ZAMEL Sundi GNT-921-CZN BIM-BAM 8V in black is a compact two-tone mechanical gong designed for low-voltage doorbell systems. The unit produces a clear BIM-BAM sound pattern at 8 V supply, intended for use at residential entrances or small commercial premises. Its unobtrusive black housing allows visible mounting on walls near entry points, and the device connects to standard low-voltage doorbell circuits for straightforward integration with existing wiring.

Advantages

The two-tone BIM-BAM mechanism provides audible differentiation that helps distinguish doorbell calls from other background sounds. The wired design ensures consistent power and reliable operation without the need for batteries. The compact enclosure in black offers discreet placement and straightforward surface mounting, while compatibility with common low-voltage doorbell wiring simplifies installation and maintenance.

Suitable for

• Residential front or back entrances
• Small offices, clinics, or retail counters
• Interior corridors where a wired door chime is preferred
• Replacement of existing low-voltage mechanical gongs

Key specifications

• Operating voltage: 8 V (low-voltage doorbell systems)
• Sound type: two-tone mechanical gong (BIM-BAM)
• Housing colour: black
• Mounting: surface mount for visible installation
• Connection: wired terminals for integration with low-voltage circuits

How to use

Connect the chime to an 8 V low-voltage doorbell transformer and the push-button circuit following the wiring diagram provided by the installer or technical documentation. Mount the unit on a flat vertical surface near the entrance at a height that provides good audibility throughout the intended area. After wiring and mounting, restore power and test by pressing the doorbell button; the chime should produce the BIM-BAM two-tone sequence. If the sound is weak or silent, verify wiring continuity and transformer output voltage.

Usage recommendations

For reliable performance, use with compatible 8 V low-voltage transformers and standard doorbell push-buttons. Avoid exposure to direct moisture; install under a sheltered area or inside a covered entryway. Periodically inspect wiring connections and mounting screws to ensure secure attachment and consistent sound output.
