Project Telecom PT102-4B GSM / 4G Push-to-Call Outdoor Phone - Blue

 The Project Telecom PT102-4B GSM / 4G Push-to-Call Outdoor Phone is a professional-grade wireless communications solution designed for dependable operation in harsh industrial, outdoor and public-access environments. Featuring four push-to-call buttons, a weatherproof protective front door, IP66 weatherproof protection, vandal-resistant construction and GSM / 4G cellular connectivity, the PT102-4B delivers reliable communications where fixed telephone lines or network infrastructure may be unavailable or impractical.

Designed for factories, warehouses, transport infrastructure, utility sites, rail networks, ports, marine environments, tunnels, construction projects, car parks and public assistance points, the PT102-4B enables users to connect with one of four independently programmed contacts at the press of a button. The four-button configuration provides maximum operational flexibility, allowing dedicated contacts for security, customer assistance, maintenance teams, control rooms, site management or emergency support services.

Its corrosion-resistant die-cast aluminium housing and weather-sealed protective front door safeguard internal components from dust, moisture and harsh weather conditions, ensuring dependable operation in demanding environments.

Heavy-Duty Construction for Harsh Environments

Engineered specifically for industrial and public-access applications, the PT102-4B features a corrosion-resistant die-cast aluminium enclosure finished with an industrial epoxy powder coating.

The heavy-duty construction offers outstanding resistance to weather, corrosion, dust, moisture, impact and vandalism. Tamper-resistant mounting bars and fixings further enhance security, making the PT102-4B suitable for exposed locations where dependable communications are essential.

Designed for years of continuous service, the telephone is ideally suited to factories, transport infrastructure, utility facilities, ports, marine environments, construction sites and other demanding applications.

Four Button Push-to-Call Operation

The PT102-4B offers simple operation through four vandal-resistant stainless-steel push-to-call buttons. Users simply press the required button to automatically call one of four independently programmed contacts without manual dialling.

The four-button configuration allows organisations to provide direct access to multiple departments or services from a single communications point.

Typical applications include - Security, Customer Assistance, Maintenance, Control Rooms, Technical Support and Site Management.

This flexibility makes the PT102-4B ideal for transport infrastructure, industrial communications, public assistance points, customer service locations and critical communications applications.

GSM / 4G Mobile Connectivity

The PT102-4B GSM / 4G version is designed for installations where traditional telephone lines or network infrastructure are unavailable, impractical or prohibitively expensive.

Operating over GSM and 4G mobile networks, the telephone provides a reliable communications solution for remote locations, temporary sites and outdoor environments without requiring fixed-line infrastructure.

The telephone accepts a Micro SIM card and supports remote programming via SMS, allowing straightforward installation, configuration and maintenance. Remote status reporting also enables efficient monitoring of deployed units.

This makes the PT102-4B particularly suitable for construction sites, remote utility installations, highways, rail infrastructure, car parks, public help points, renewable energy sites and temporary works.

Handsfree Communication

Designed as a fully handsfree communication device, the PT102-4B provides clear, natural two-way voice communication without requiring a handset.

Its handsfree operation improves reliability by eliminating handset-related wear whilst reducing ongoing maintenance in busy industrial, transport and public-access environments.

IP66 Weatherproof Protection

The PT102-4B is housed within a robust weatherproof enclosure featuring a weather-sealed protective front door, providing IP66-rated protection against dust ingress, rain, moisture and water exposure.

For applications requiring increased environmental protection, an IP67 version is available on request.

Designed for year-round outdoor deployment, the enclosure helps maintain reliable communications in exposed industrial and public-access environments.

Accessibility & User Safety Features

Where hearing aid compatibility is required, an optional inductive coupler can be supplied. This optional feature improves accessibility whilst maintaining the telephone's straightforward handsfree operation.

*Note - Hearing aid symbol shown in product images for illustrative purposes only. Inductive coupler available on request at an additional cost.

The PT102-4B also incorporates non-volatile memory, ensuring programmed settings are retained during power interruptions to minimise maintenance and maintain reliable long-term operation.
