Talk through glass systems, also known as window intercoms or counter intercoms, are specialist communication solutions designed to provide clear, two-way audio across physical barriers such as security glass, screens, or partitions. These window intercom systems overcome the common problem of muffled voices and poor communication in service environments, ensuring staff and customers can converse naturally and effectively.
Our range includes complete talk through glass kits with different speaker and microphone configurations. Options feature surface-mounted or flush-mounted speakers with integrated microphones, as well as models with built-in counter induction loops that simultaneously support hearing aid users. Available in both black and grey finishes, these systems are compact, easy to install, and deliver high-clarity audio with volume control for both sides.
These commercial window intercoms are widely used in banks, post offices, pharmacies, ticket counters, reception desks, petrol station kiosks, secure entrances, and healthcare facilities. They are particularly valuable wherever safety glass or protective screens create a barrier between staff and the public, such as in retail, local government offices, and transport hubs.
By improving speech intelligibility and supporting accessibility through integrated induction loops, talk through glass systems enhance customer service while maintaining security. They are a simple yet highly effective way to boost both staff efficiency and user satisfaction.

It is a two-way window intercom so staff and customers can speak clearly through security glass, a hygiene screen or a partition. Microphones and speakers on each side, plus an amplifier, replace raised voices and muffled speech at a counter. This range of Contacta STS kits includes a hearing loop.
Typically installed in banks, post offices, pharmacies, ticket desks, receptions, petrol-station kiosks, secure entrances, healthcare counters, local-government windows and transport hubs — anywhere a protective screen sits between staff and the public.
STS-K003L uses flush-mounted customer speakers with an integral microphone (tidier, better in quieter spaces). STS-K002L uses surface-mounted / free-standing customer speakers (faster to fit, no cut-out in the fascia). STS-K001L is the fixed-position / bridge-bar kit. All three include a counter induction loop and are sold in black or grey.
Choose flush (K003) when the counter can be cut and you want a low-profile finish. Choose surface (K002) when you cannot cut the desk or need a same-day retrofit. Flush kits are generally better in low ambient noise; a busy ticket hall may need careful placement and volume setup on either type.
No. The system transfers speech electronically through the amplifier, so you do not rely on a voice hole in the glass. You still need space to mount the customer speaker/mic, the staff unit and the under-counter amplifier, and a route for the kit’s cables.
Every kit in this range includes a counter loop (coil about 55 × 51 cm) driven from the amplifier. Hearing-aid users switch to Telecoil (T) and hear the staff side in their aid. Correctly installed, the loop is intended to meet hearing-loop performance standards such as IEC 60118-4 / BS EN 60118-4. Display the hearing-loop sign supplied in the kit.
The loop coil supplied in the kit measures 55cm x 51cm.
A typical kit includes the customer speaker/mic, staff loudspeaker-microphone (semi-rigid stem, mute), STS-A31 amplifier, power supply, hearing-loop aerial, cables and fixings. The amplifier is a 12–14 V DC full-duplex unit that usually mounts under the staff counter. Warranty on the listed Contacta kits is 1 year.
The cables supplied in the kit are 3 metres long.
Only for the desk. Black (suffix -B) and grey (suffix -G) are the same system. Match the staff mic and customer units to the counter and screen so the intercom does not look like an afterthought.
