Frequently Asked Questions

How is a speak-thru system different from a window intercom system?

A speak-thru system (or voice port) is a passive, non-powered device that allows clear communication through bullet-resistant glass using specially designed openings. Intercom systems are active, powered devices that rely on microphones and speakers to transmit sound through barriers.

Do you recommend intercom systems for bulletproof transaction windows?

While intercoms can be useful in some high-noise or outdoor environments, we generally recommend passive voice transmission systems whenever possible. Intercoms require power, can introduce issues like crosstalk or static, and often need regular adjustments. Passive speak-thru systems offer a clearer, more reliable way to communicate with less maintenance and fewer complications.

What factors should I consider when choosing a window speak-thru system?

When selecting a speak-thru, consider where and how it will be used. Interior windows often work well with passive options like baffles, arched openings, or hole-and-backer systems, while electronic speaker systems are almost always the rule in exterior windows.

Window size, sound direction, and employee/customer positioning all affect clarity: larger windows may benefit from center-mounted ports instead of side baffles. You'll also want to match your speak-thru to the bullet-resistance level of the glass (per UL 752) and ensure the design supports both your security and aesthetic goals.

What other accessories can be added to a bulletproof transaction window?

In addition to speak-thru systems, bulletproof transaction windows can be customized with a range of functional accessories. This includes currency trays for secure cash exchange, package passers for larger items, and locking or non-locking transaction drawers. TSS can tailor these components to your daily operations and seamlessly integrate them into your window system.
