Safety-Comm SC-350 Amplified Window Intercom System. The Versatile Choice.


( / )

Please select all options.

The SC-350 window intercom is your best choice if the window has limited interior depth for mounting the customer unit in the window hole. A roll-down door, fire shutters, mini-blinds, or other hindrances are factors to consider. The customer unit requires only 2 1/4" inches of depth for proper mounting. 

The SC-300 operator unit mounts to the counter at a convenient location of your choice. Ordering the SC-350 window intercom includes all the controls, power supply and completes the set.

This Window Intercom requires a hole in the glass window. If your window doesn't have a hole, we suggest the SC-300

**Key Features:**

1. **Crystal Clear Sound:** Experience exceptional audio clarity, enabling smooth conversations even in noisy surroundings.

2. **Advanced Noise Cancellation:** Minimize background noise for improved communication accuracy and privacy.

3. **Durable Construction:** Built to withstand the rigors of daily use, ensuring long-lasting performance and reliability.

4. **Easy Installation:** Simple to set up and operate, requiring no specialized tools or expertise.

Perfect Applications for HavenTech SC-350 Window Intercom
The SC-350 is the smart choice for installations in which a full-depth window intercom is impractical,
such as when mini-blinds or fire shutters are installed in the window frame. The base unit and remote units
are "hands free", and the base unit incorporates an 18” gooseneck mic to allow for conveniently positioning
the base unit when staff is using a computer.
