PT102-3B 3 Button Push-to-Call Outdoor Phone

The Project Telecom PT102-3B 3 Button Push-to-Call Outdoor Phone is a robust, professional communications device engineered for reliable performance in demanding industrial, outdoor and public-access environments. With three push-to-call buttons, IP66-rated weatherproof protection, a sealed protective front cover, vandal-resistant construction and the option of Analogue, SIP or GSM / 4G connectivity, it provides dependable communication where standard telephone systems may not be suitable.

Ideal for deployment in factories, warehouses, transport networks, utility sites, rail infrastructure, ports, marine environments, tunnels, construction areas, car parks and public help points, the PT102-3B allows users to instantly connect to one of three pre-set destinations at the press of a button. This configuration enables organisations to assign dedicated contacts such as security teams, customer service, maintenance departments, control rooms or emergency response personnel.

Its rugged die-cast aluminium housing and weatherproof front door protect internal electronics from dust, moisture and harsh environmental conditions, ensuring consistent performance in exposed locations. The model is available in Yellow, Blue, Red and Grey finishes, allowing selection based on visibility requirements, safety standards or site design preferences.

Heavy-Duty Design for Industrial Environments

Built specifically for tough operational settings, the PT102-3B features a corrosion-resistant die-cast aluminium enclosure finished with a durable industrial epoxy powder coating.

This construction provides strong resistance to impact, vandalism, moisture, dust ingress and corrosion. Reinforced tamper-resistant fixings further enhance security, making the unit suitable for unsupervised and high-risk environments where reliability is essential.

Designed for continuous long-term use, the PT102-3B delivers dependable performance across industrial facilities, transport hubs, utilities, ports, construction sites and other harsh environments.

Three Button Push-to-Call Operation

Operation is simple and intuitive via three stainless-steel vandal-resistant push buttons, each programmed to dial a specific pre-set number automatically.

This three-point calling system allows organisations to centralise multiple communication routes into a single device, improving response efficiency and accessibility.

This makes the PT102-3B particularly effective in transport terminals, industrial sites and public-facing installations where rapid access to multiple services is required.

Flexible Connectivity Options

The PT102-3B is available in Analogue, SIP and GSM/4G variants, enabling integration with a wide range of communication infrastructures.

Analogue Version

The analogue model connects directly to PSTN and analogue PABX systems, offering a straightforward, line-powered solution with no additional network requirements.

SIP Version

The SIP variant supports SIP 2.0 (RFC3261) and integrates seamlessly with SIP PBX platforms, hosted VoIP systems and IP-based enterprise networks. Features include PoE support, dual SIP registration and web-based configuration for flexible deployment.

GSM / 4G Version

The GSM/4G model operates via mobile networks using a Micro SIM card, making it ideal for remote or infrastructure-limited locations. It also supports SMS-based configuration and remote status monitoring for simplified management.

Handsfree Voice Communication

Designed for fully handsfree operation, the PT102-3B delivers clear, reliable two-way voice communication without the need for a handset.

Its full duplex audio system supports natural conversation flow, while improving durability and reducing wear and tear associated with traditional handset-based designs. This makes it well suited for high-usage environments where reliability is critical.

IP66 Weatherproof Protection

The PT102-3B is enclosed in a sealed, weather-resistant housing with a protective front door, providing IP66-rated protection against dust and water ingress.

For installations requiring enhanced environmental protection, an IP67-rated version is available on request.

Designed for permanent outdoor use, the enclosure ensures continued operation in harsh and exposed environments, maintaining communications reliability throughout the year.

Accessibility & System Reliability

For improved accessibility, the PT102-3B can be fitted with an optional inductive coupler, enabling better compatibility with hearing aids while retaining simple handsfree operation.

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

The device also features non-volatile memory, ensuring programmed settings are retained during power interruptions. This helps maintain system reliability and reduces maintenance requirements over time.
