Key Features of "Push to Talk"
"Push to talk" (PTT) requires users to press the PTT button to activate the microphone to transmit their voice. This feature manages clear communication by:
- Preventing overlapping conversations
- One-way communication: Only one person can speak at a time
- Clarity in noisy settings: Avoids confusion in loud environments
- Controls the communication flow
PTT is an effective method for clear, controlled two-way communication in intercom systems, particularly beneficial for business customers operating in noisy environments.
Key Features of "Push to Override"
"Push to Override" (PTO) allows users to temporarily take control of the communication channel by pressing the blue button overriding normal settings. This feature is useful when the system is in hands-free or automatic mode.
By pressing the Blue "push to override" button,
- The operator controls the interaction between the parties.
- Bypasses automatic settings to guarantee clear communication even in challenging ambient noise surroundings
- A very effective tool to override the visitor's mic, thereby giving uninterrupted speech to the operator
- Provides manual control over the intercom's audio system
PTO is an effective method for managing the controlled two-way communication in our window intercom systems, and particularly beneficial for business customers operating in noisy environments.

Talk all day with Rechargeable Lithium-ion battery
On an overnight charge, the internal rechargeable Lithium-ion battery provides 8-10hours of duty time.* Many customers prefer the battery version because there is
no cable or conduit to obstruct the window.

A jack on the Staff side of the unit for connecting
the battery charger, which requires a standard 110v wall outlet nearby.
*duty time = assumes 30% talk time, 70% idle time
Easy, less than 1 hour installation.

Where it's deployed

Analog vs Digital Connections
HavenTech analog window intercoms do not require internet access, Wi-Fi, cloud service, LAN connection, or remote login. They are built for direct, local voice communication through secure service windows and glass barriers.
That matters because this intercom does not add another network-connected device for IT or security teams to manage. No IP address. No remote access path. No internet-based firmware risk. No patch cycle for the intercom itself.
For buyers, specifiers, and procurement teams, this is practical forethought: clear communication without unnecessary network exposure. You have done your due diligence. Deliberately offline. No network. Lower cyber exposure.
